This getter should be used only on elements that contain a directive which starts a new isolate + * scope.

The attributes are: + * + * #### `multiElement` + * When this property is set to true, the HTML compiler will collect DOM nodes between + * nodes with the attributes `directive-name-start` and `directive-name-end`, and group them + * together as the directive elements. It is recomended that this feature be used on directives + * which are not strictly behavioural (such as {@link api/ng.directive:ngClick ngClick}), and which + * do not manipulate or replace child nodes (such as {@link api/ng.directive:ngInclude ngInclude}). + * + * #### `priority` + * When there are multiple directives defined on a single DOM element, sometimes it + * is necessary to specify the order in which the directives are applied. The `priority` is used + * to sort the directives before their `compile` functions get called. Priority is defined as a + * number. Directives with greater numerical `priority` are compiled first. Pre-link functions + * are also run in priority order, but post-link functions are run in reverse order. The order + * of directives with the same priority is undefined. The default priority is `0`. + * + * #### `terminal` + * If set to true then the current `priority` will be the last set of directives + * which will execute (any directives at the current priority will still execute + * as the order of execution on same `priority` is undefined). + * + * #### `scope` + * **If set to `true`,** then a new scope will be created for this directive. If multiple directives on the + * same element request a new scope, only one new scope is created. The new scope rule does not + * apply for the root of the template since the root of the template always gets a new scope. + * + * **If set to `{}` (object hash),** then a new "isolate" scope is created. The 'isolate' scope differs from + * normal scope in that it does not prototypically inherit from the parent scope. This is useful + * when creating reusable components, which should not accidentally read or modify data in the + * parent scope. + * + * The 'isolate' scope takes an object hash which defines a set of local scope properties + * derived from the parent scope. These local properties are useful for aliasing values for + * templates. Locals definition is a hash of local scope property to its source: + * + * * `@` or `@attr` - bind a local scope property to the value of DOM attribute. The result is + * always a string since DOM attributes are strings. If no `attr` name is specified then the + * attribute name is assumed to be the same as the local name. + * Given `<widget my-attr="hello {{name}}">` and widget definition + * of `scope: { localName:'@myAttr' }`, then widget scope property `localName` will reflect + * the interpolated value of `hello {{name}}`. As the `name` attribute changes so will the + * `localName` property on the widget scope. The `name` is read from the parent scope (not + * component scope). + * + * * `=` or `=attr` - set up bi-directional binding between a local scope property and the + * parent scope property of name defined via the value of the `attr` attribute. If no `attr` + * name is specified then the attribute name is assumed to be the same as the local name. + * Given `<widget my-attr="parentModel">` and widget definition of + * `scope: { localModel:'=myAttr' }`, then widget scope property `localModel` will reflect the + * value of `parentModel` on the parent scope. Any changes to `parentModel` will be reflected + * in `localModel` and any changes in `localModel` will reflect in `parentModel`. If the parent + * scope property doesn't exist, it will throw a NON_ASSIGNABLE_MODEL_EXPRESSION exception. You + * can avoid this behavior using `=?` or `=?attr` in order to flag the property as optional. + * + * * `&` or `&attr` - provides a way to execute an expression in the context of the parent scope. + * If no `attr` name is specified then the attribute name is assumed to be the same as the + * local name. Given `<widget my-attr="count = count + value">` and widget definition of + * `scope: { localFn:'&myAttr' }`, then isolate scope property `localFn` will point to + * a function wrapper for the `count = count + value` expression. Often it's desirable to + * pass data from the isolated scope via an expression to the parent scope, this can be + * done by passing a map of local variable names and values into the expression wrapper fn. + * For example, if the expression is `increment(amount)` then we can specify the amount value + * by calling the `localFn` as `localFn({amount: 22})`. + * + * + * #### `bindToController` + * When an isolate scope is used for a component (see above), and `controllerAs` is used, `bindToController` will + * allow a component to have its properties bound to the controller, rather than to scope. When the controller + * is instantiated, the initial values of the isolate scope bindings are already available. + * + * #### `controller` + * Controller constructor function. The controller is instantiated before the + * pre-linking phase and it is shared with other directives (see + * `require` attribute). This allows the directives to communicate with each other and augment + * each other's behavior. The controller is injectable (and supports bracket notation) with the following locals: + * + * * `$scope` - Current scope associated with the element + * * `$element` - Current element + * * `$attrs` - Current attributes object for the element + * * `$transclude` - A transclude linking function pre-bound to the correct transclusion scope: + * `function([scope], cloneLinkingFn, futureParentElement)`. + * * `scope`: optional argument to override the scope. + * * `cloneLinkingFn`: optional argument to create clones of the original transcluded content. + * * `futureParentElement`: + * * defines the parent to which the `cloneLinkingFn` will add the cloned elements. + * * default: `$element.parent()` resp. `$element` for `transclude:'element'` resp. `transclude:true`. + * * only needed for transcludes that are allowed to contain non html elements (e.g. SVG elements) + * and when the `cloneLinkinFn` is passed, + * as those elements need to created and cloned in a special way when they are defined outside their + * usual containers (e.g. like `<svg>`). + * * See also the `directive.templateNamespace` property. + * + * + * #### `require` + * Require another directive and inject its controller as the fourth argument to the linking function. The + * `require` takes a string name (or array of strings) of the directive(s) to pass in. If an array is used, the + * injected argument will be an array in corresponding order. If no such directive can be + * found, or if the directive does not have a controller, then an error is raised. The name can be prefixed with: + * + * * (no prefix) - Locate the required controller on the current element. Throw an error if not found. + * * `?` - Attempt to locate the required controller or pass `null` to the `link` fn if not found. + * * `^` - Locate the required controller by searching the element and its parents. Throw an error if not found. + * * `?^` - Attempt to locate the required controller by searching the element and its parents or pass + * `null` to the `link` fn if not found. + * + * + * #### `controllerAs` + * Controller alias at the directive scope. An alias for the controller so it + * can be referenced at the directive template. The directive needs to define a scope for this + * configuration to be used. Useful in the case when directive is used as component. + * + * + * #### `restrict` + * String of subset of `EACM` which restricts the directive to a specific directive + * declaration style. If omitted, the defaults (elements and attributes) are used. + * + * * `E` - Element name (default): `<my-directive></my-directive>` + * * `A` - Attribute (default): `<div my-directive="exp"></div>` + * * `C` - Class: `<div class="my-directive: exp;"></div>` + * * `M` - Comment: `<!-- directive: my-directive exp -->` + * + * + * #### `templateNamespace` + * String representing the document type used by the markup in the template. + * AngularJS needs this information as those elements need to be created and cloned + * in a special way when they are defined outside their usual containers like `<svg>` and `<math>`. + * + * * `html` - All root nodes in the template are HTML. Root nodes may also be + * top-level elements such as `<svg>` or `<math>`. + * * `svg` - The root nodes in the template are SVG elements (excluding `<math>`). + * * `math` - The root nodes in the template are MathML elements (excluding `<svg>`). + * + * If no `templateNamespace` is specified, then the namespace is considered to be `html`. + * + * #### `template` + * HTML markup that may: + * * Replace the contents of the directive's element (default). + * * Replace the directive's element itself (if `replace` is true - DEPRECATED). + * * Wrap the contents of the directive's element (if `transclude` is true). + * + * Value may be: + * + * * A string. For example `<div red-on-hover>{{delete_str}}</div>`. + * * A function which takes two arguments `tElement` and `tAttrs` (described in the `compile` + * function api below) and returns a string value. + * + * + * #### `templateUrl` + * This is similar to `template` but the template is loaded from the specified URL, asynchronously. + * + * Because template loading is asynchronous the compiler will suspend compilation of directives on that element + * for later when the template has been resolved. In the meantime it will continue to compile and link + * sibling and parent elements as though this element had not contained any directives. + * + * The compiler does not suspend the entire compilation to wait for templates to be loaded because this + * would result in the whole app "stalling" until all templates are loaded asynchronously - even in the + * case when only one deeply nested directive has `templateUrl`. + * + * Template loading is asynchronous even if the template has been preloaded into the {@link $templateCache} + * + * You can specify `templateUrl` as a string representing the URL or as a function which takes two + * arguments `tElement` and `tAttrs` (described in the `compile` function api below) and returns + * a string value representing the url. In either case, the template URL is passed through {@link + * api/ng.$sce#getTrustedResourceUrl $sce.getTrustedResourceUrl}. + * + * + * #### `replace` ([*DEPRECATED*!], will be removed in next major release - i.e. v2.0) + * specify what the template should replace. Defaults to `false`. + * + * * `true` - the template will replace the directive's element. + * * `false` - the template will replace the contents of the directive's element. + * + * The replacement process migrates all of the attributes / classes from the old element to the new + * one. See the {@link guide/directive#creating-custom-directives_creating-directives_template-expanding-directive + * Directives Guide} for an example. + * + * There are very few scenarios where element replacement is required for the application function, + * the main one being reusable custom components that are used within SVG contexts + * (because SVG doesn't work with custom elements in the DOM tree). + * + * #### `transclude` + * compile the content of the element and make it available to the directive. + * Typically used with {@link ng.directive:ngTransclude + * ngTransclude}. The advantage of transclusion is that the linking function receives a + * transclusion function which is pre-bound to the correct scope. In a typical setup the widget + * creates an `isolate` scope, but the transclusion is not a child, but a sibling of the `isolate` + * scope. This makes it possible for the widget to have private state, and the transclusion to + * be bound to the parent (pre-`isolate`) scope. + * + * * `true` - transclude the content of the directive. + * * `'element'` - transclude the whole element including any directives defined at lower priority. + * + * <div class="alert alert-warning"> + * **Note:** When testing an element transclude directive you must not place the directive at the root of the + * DOM fragment that is being compiled. See {@link guide/unit-testing#testing-transclusion-directives + * Testing Transclusion Directives}. + * </div> + * + * #### `compile` + * + * ```js + * function compile(tElement, tAttrs, transclude) { ... } + * ``` + * + * The compile function deals with transforming the template DOM. Since most directives do not do + * template transformation, it is not used often. The compile function takes the following arguments: + * + * * `tElement` - template element - The element where the directive has been declared. It is + * safe to do template transformation on the element and child elements only. + * + * * `tAttrs` - template attributes - Normalized list of attributes declared on this element shared + * between all directive compile functions. + * + * * `transclude` - [*DEPRECATED*!] A transclude linking function: `function(scope, cloneLinkingFn)` + * + * <div class="alert alert-warning"> + * **Note:** The template instance and the link instance may be different objects if the template has + * been cloned. For this reason it is **not** safe to do anything other than DOM transformations that + * apply to all cloned DOM nodes within the compile function. Specifically, DOM listener registration + * should be done in a linking function rather than in a compile function. + * </div> + + * <div class="alert alert-warning"> + * **Note:** The compile function cannot handle directives that recursively use themselves in their + * own templates or compile functions. Compiling these directives results in an infinite loop and a + * stack overflow errors. + * + * This can be avoided by manually using $compile in the postLink function to imperatively compile + * a directive's template instead of relying on automatic template compilation via `template` or + * `templateUrl` declaration or manual compilation inside the compile function. + * </div> + * + * <div class="alert alert-error"> + * **Note:** The `transclude` function that is passed to the compile function is deprecated, as it + * e.g. does not know about the right outer scope. Please use the transclude function that is passed + * to the link function instead. + * </div> + + * A compile function can have a return value which can be either a function or an object. + * + * * returning a (post-link) function - is equivalent to registering the linking function via the + * `link` property of the config object when the compile function is empty. + * + * * returning an object with function(s) registered via `pre` and `post` properties - allows you to + * control when a linking function should be called during the linking phase. See info about + * pre-linking and post-linking functions below. + * + * + * #### `link` + * This property is used only if the `compile` property is not defined. + * + * ```js + * function link(scope, iElement, iAttrs, controller, transcludeFn) { ... } + * ``` + * + * The link function is responsible for registering DOM listeners as well as updating the DOM. It is + * executed after the template has been cloned. This is where most of the directive logic will be + * put. + * + * * `scope` - {@link ng.$rootScope.Scope Scope} - The scope to be used by the + * directive for registering {@link ng.$rootScope.Scope#$watch watches}. + * + * * `iElement` - instance element - The element where the directive is to be used. It is safe to + * manipulate the children of the element only in `postLink` function since the children have + * already been linked. + * + * * `iAttrs` - instance attributes - Normalized list of attributes declared on this element shared + * between all directive linking functions. + * + * * `controller` - a controller instance - A controller instance if at least one directive on the + * element defines a controller. The controller is shared among all the directives, which allows + * the directives to use the controllers as a communication channel. + * + * * `transcludeFn` - A transclude linking function pre-bound to the correct transclusion scope. + * This is the same as the `$transclude` + * parameter of directive controllers, see there for details. + * `function([scope], cloneLinkingFn, futureParentElement)`. + * + * #### Pre-linking function + * + * Executed before the child elements are linked. Not safe to do DOM transformation since the + * compiler linking function will fail to locate the correct elements for linking. + * + * #### Post-linking function + * + * Executed after the child elements are linked. + * + * Note that child elements that contain `templateUrl` directives will not have been compiled + * and linked since they are waiting for their template to load asynchronously and their own + * compilation and linking has been suspended until that occurs. + * + * It is safe to do DOM transformation in the post-linking function on elements that are not waiting + * for their async templates to be resolved. + * + * <a name="Attributes"></a> + * ### Attributes + * + * The {@link ng.$compile.directive.Attributes Attributes} object - passed as a parameter in the + * `link()` or `compile()` functions. It has a variety of uses. + * + * accessing *Normalized attribute names:* + * Directives like 'ngBind' can be expressed in many ways: 'ng:bind', `data-ng-bind`, or 'x-ng-bind'. + * the attributes object allows for normalized access to + * the attributes. + * + * * *Directive inter-communication:* All directives share the same instance of the attributes + * object which allows the directives to use the attributes object as inter directive + * communication. + * + * * *Supports interpolation:* Interpolation attributes are assigned to the attribute object + * allowing other directives to read the interpolated value. + * + * * *Observing interpolated attributes:* Use `$observe` to observe the value changes of attributes + * that contain interpolation (e.g. `src="{{bar}}"`). Not only is this very efficient but it's also + * the only way to easily get the actual value because during the linking phase the interpolation + * hasn't been evaluated yet and so the value is at this time set to `undefined`. + * + * ```js + * function linkingFn(scope, elm, attrs, ctrl) { + * // get the attribute value + * console.log(attrs.ngModel); + * + * // change the attribute + * attrs.$set('ngModel', 'new value'); + * + * // observe changes to interpolated attribute + * attrs.$observe('ngModel', function(value) { + * console.log('ngModel has changed value to ' + value); + * }); + * } + * ``` + * + * Below is an example using `$compileProvider`. + * + * <div class="alert alert-warning"> + * **Note**: Typically directives are registered with `module.directive`.

Where: + * + * * `scope` - A {@link ng.$rootScope.Scope Scope} to bind to. + * * `cloneAttachFn` - If `cloneAttachFn` is provided, then the link function will clone the + * `template` and call the `cloneAttachFn` function allowing the caller to attach the + * cloned elements to the DOM document at the appropriate place. The `cloneAttachFn` is + * called as: <br> `cloneAttachFn(clonedElement, scope)` where: + * + * * `clonedElement` - is a clone of the original `element` passed into the compiler. + * * `scope` - is the current scope with which the linking function is working with. + * + * Calling the linking function returns the element of the template.

While for simple usage patterns this doesn't matter much, for advanced usage + * it is important to familiarize yourself with these APIs and the guarantees they provide. + * + * + * ## General usage + * The `$http` service is a function which takes a single argument — a configuration object — + * that is used to generate an HTTP request and returns a {@link ng.$q promise} + * with two $http specific methods: `success` and `error`. + * + * ```js + * $http({method: 'GET', url: '/someUrl'}). + * success(function(data, status, headers, config) { + * // this callback will be called asynchronously + * // when the response is available + * }). + * error(function(data, status, headers, config) { + * // called asynchronously if an error occurs + * // or server returns response with an error status. + * }); + * ``` + * + * Since the returned value of calling the $http function is a `promise`, you can also use + * the `then` method to register callbacks, and these callbacks will receive a single argument – + * an object representing the response. See the API signature and type info below for more + * details. + * + * A response status code between 200 and 299 is considered a success status and + * will result in the success callback being called. Note that if the response is a redirect, + * XMLHttpRequest will transparently follow it, meaning that the error callback will not be + * called for such responses. + * + * ## Writing Unit Tests that use $http + * When unit testing (using {@link ngMock ngMock}), it is necessary to call + * {@link ngMock.$httpBackend#flush $httpBackend.flush()} to flush each pending + * request using trained responses. + * + * ``` + * $httpBackend.expectGET(...); + * $http.get(...); + * $httpBackend.flush(); + * ``` + * + * ## Shortcut methods + * + * Shortcut methods are also available. All shortcut methods require passing in the URL, and + * request data must be passed in for POST/PUT requests. + * + * ```js + * $http.get('/someUrl').success(successCallback); + * $http.post('/someUrl', data).success(successCallback); + * ``` + * + * Complete list of shortcut methods: + * + * - {@link ng.$http#get $http.get} + * - {@link ng.$http#head $http.head} + * - {@link ng.$http#post $http.post} + * - {@link ng.$http#put $http.put} + * - {@link ng.$http#delete $http.delete} + * - {@link ng.$http#jsonp $http.jsonp} + * - {@link ng.$http#patch $http.patch} + * + * + * ## Setting HTTP Headers + * + * The $http service will automatically add certain HTTP headers to all requests. These defaults + * can be fully configured by accessing the `$httpProvider.defaults.headers` configuration + * object, which currently contains this default configuration: + * + * - `$httpProvider.defaults.headers.common` (headers that are common for all requests): + * - `Accept: application/json, text/plain, * / *` + * - `$httpProvider.defaults.headers.post`: (header defaults for POST requests) + * - `Content-Type: application/json` + * - `$httpProvider.defaults.headers.put` (header defaults for PUT requests) + * - `Content-Type: application/json` + * + * To add or overwrite these defaults, simply add or remove a property from these configuration + * objects. To add headers for an HTTP method other than POST or PUT, simply add a new object + * with the lowercased HTTP method name as the key, e.g. + * `$httpProvider.defaults.headers.get = { 'My-Header' : 'value' }. + * + * The defaults can also be set at runtime via the `$http.defaults` object in the same + * fashion. For example: + * + * ``` + * module.run(function($http) { + * $http.defaults.headers.common.Authorization = 'Basic YmVlcDpib29w' + * }); + * ``` + * + * In addition, you can supply a `headers` property in the config object passed when + * calling `$http(config)`, which overrides the defaults without changing them globally. + * + * + * ## Transforming Requests and Responses + * + * Both requests and responses can be transformed using transformation functions: `transformRequest` + * and `transformResponse`. These properties can be a single function that returns + * the transformed value (`{function(data, headersGetter)`) or an array of such transformation functions, + * which allows you to `push` or `unshift` a new transformation function into the transformation chain. + * + * ### Default Transformations + * + * The `$httpProvider` provider and `$http` service expose `defaults.transformRequest` and + * `defaults.transformResponse` properties. If a request does not provide its own transformations + * then these will be applied. + * + * You can augment or replace the default transformations by modifying these properties by adding to or + * replacing the array. + * + * Angular provides the following default transformations: + * + * Request transformations (`$httpProvider.defaults.transformRequest` and `$http.defaults.transformRequest`): + * + * - If the `data` property of the request configuration object contains an object, serialize it + * into JSON format. + * + * Response transformations (`$httpProvider.defaults.transformResponse` and `$http.defaults.transformResponse`): + * + * - If XSRF prefix is detected, strip it (see Security Considerations section below). + * - If JSON response is detected, deserialize it using a JSON parser. + * + * + * ### Overriding the Default Transformations Per Request + * + * If you wish override the request/response transformations only for a single request then provide + * `transformRequest` and/or `transformResponse` properties on the configuration object passed + * into `$http`. + * + * Note that if you provide these properties on the config object the default transformations will be + * overwritten. If you wish to augment the default transformations then you must include them in your + * local transformation array. + * + * The following code demonstrates adding a new response transformation to be run after the default response + * transformations have been run. + * + * ```js + * function appendTransform(defaults, transform) { + * + * // We can't guarantee that the default transformation is an array + * defaults = angular.isArray(defaults) ? defaults : [defaults]; + * + * // Append the new transformation to the defaults + * return defaults.concat(transform); + * } + * + * $http({ + * url: '...', + * method: 'GET', + * transformResponse: appendTransform($http.defaults.transformResponse, function(value) { + * return doTransform(value); + * }) + * }); + * ``` + * + * + * ## Caching + * + * To enable caching, set the request configuration `cache` property to `true` (to use default + * cache) or to a custom cache object (built with {@link ng.$cacheFactory `$cacheFactory`}). + * When the cache is enabled, `$http` stores the response from the server in the specified + * cache. The next time the same request is made, the response is served from the cache without + * sending a request to the server. + * + * Note that even if the response is served from cache, delivery of the data is asynchronous in + * the same way that real requests are. + * + * If there are multiple GET requests for the same URL that should be cached using the same + * cache, but the cache is not populated yet, only one request to the server will be made and + * the remaining requests will be fulfilled using the response from the first request. + * + * You can change the default cache to a new object (built with + * {@link ng.$cacheFactory `$cacheFactory`}) by updating the + * {@link ng.$http#properties_defaults `$http.defaults.cache`} property. All requests who set + * their `cache` property to `true` will now use this cache object. + * + * If you set the default cache to `false` then only requests that specify their own custom + * cache object will be cached. + * + * ## Interceptors + * + * Before you start creating interceptors, be sure to understand the + * {@link ng.$q $q and deferred/promise APIs}. + * + * For purposes of global error handling, authentication, or any kind of synchronous or + * asynchronous pre-processing of request or postprocessing of responses, it is desirable to be + * able to intercept requests before they are handed to the server and + * responses before they are handed over to the application code that + * initiated these requests. The interceptors leverage the {@link ng.$q + * promise APIs} to fulfill this need for both synchronous and asynchronous pre-processing. + * + * The interceptors are service factories that are registered with the `$httpProvider` by + * adding them to the `$httpProvider.interceptors` array. The factory is called and + * injected with dependencies (if specified) and returns the interceptor. + * + * There are two kinds of interceptors (and two kinds of rejection interceptors): + * + * * `request`: interceptors get called with a http `config` object. The function is free to + * modify the `config` object or create a new one. The function needs to return the `config` + * object directly, or a promise containing the `config` or a new `config` object. + * * `requestError`: interceptor gets called when a previous interceptor threw an error or + * resolved with a rejection. + * * `response`: interceptors get called with http `response` object. The function is free to + * modify the `response` object or create a new one. The function needs to return the `response` + * object directly, or as a promise containing the `response` or a new `response` object. + * * `responseError`: interceptor gets called when a previous interceptor threw an error or + * resolved with a rejection. + * + * + * ```js + * // register the interceptor as a service + * $provide.factory('myHttpInterceptor', function($q, dependency1, dependency2) { + * return { + * // optional method + * 'request': function(config) { + * // do something on success + * return config; + * }, + * + * // optional method + * 'requestError': function(rejection) { + * // do something on error + * if (canRecover(rejection)) { + * return responseOrNewPromise + * } + * return $q.reject(rejection); + * }, + * + * + * + * // optional method + * 'response': function(response) { + * // do something on success + * return response; + * }, + * + * // optional method + * 'responseError': function(rejection) { + * // do something on error + * if (canRecover(rejection)) { + * return responseOrNewPromise + * } + * return $q.reject(rejection); + * } + * }; + * }); + * + * $httpProvider.interceptors.push('myHttpInterceptor'); + * + * + * // alternatively, register the interceptor via an anonymous factory + * $httpProvider.interceptors.push(function($q, dependency1, dependency2) { + * return { + * 'request': function(config) { + * // same as above + * }, + * + * 'response': function(response) { + * // same as above + * } + * }; + * }); + * ``` + * + * ## Security Considerations + * + * When designing web applications, consider security threats from: + * + * - [JSON vulnerability](http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx) + * - [XSRF](http://en.wikipedia.org/wiki/Cross-site_request_forgery) + * + * Both server and the client must cooperate in order to eliminate these threats. Angular comes + * pre-configured with strategies that address these issues, but for this to work backend server + * cooperation is required. + * + * ### JSON Vulnerability Protection + * + * A [JSON vulnerability](http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx) + * allows third party website to turn your JSON resource URL into + * [JSONP](http://en.wikipedia.org/wiki/JSONP) request under some conditions. To + * counter this your server can prefix all JSON requests with following string `")]}',\n"`. + * Angular will automatically strip the prefix before processing it as JSON. + * + * For example if your server needs to return: + * ```js + * ['one','two'] + * ``` + * + * which is vulnerable to attack, your server can return: + * ```js + * )]}', + * ['one','two'] + * ``` + * + * Angular will strip the prefix, before processing the JSON. + * + * + * ### Cross Site Request Forgery (XSRF) Protection + * + * [XSRF](http://en.wikipedia.org/wiki/Cross-site_request_forgery) is a technique by which + * an unauthorized site can gain your user's private data. Angular provides a mechanism + * to counter XSRF. When performing XHR requests, the $http service reads a token from a cookie + * (by default, `XSRF-TOKEN`) and sets it as an HTTP header (`X-XSRF-TOKEN`). Since only + * JavaScript that runs on your domain could read the cookie, your server can be assured that + * the XHR came from JavaScript running on your domain. The header will not be set for + * cross-domain requests. + * + * To take advantage of this, your server needs to set a token in a JavaScript readable session + * cookie called `XSRF-TOKEN` on the first HTTP GET request. On subsequent XHR requests the + * server can verify that the cookie matches `X-XSRF-TOKEN` HTTP header, and therefore be sure + * that only JavaScript running on your domain could have sent the request. The token must be + * unique for each user and must be verifiable by the server (to prevent the JavaScript from + * making up its own tokens). We recommend that the token is a digest of your site's + * authentication cookie with a [salt](https://en.wikipedia.org/wiki/Salt_(cryptography)) + * for added security. + * + * The name of the headers can be specified using the xsrfHeaderName and xsrfCookieName + * properties of either $httpProvider.defaults at config-time, $http.defaults at run-time, + * or the per-request config object. + * + * + * @param {object} config Object describing the request to be made and how it should be + * processed. The object has following properties: + * + * - **method** – `{string}` – HTTP method (e.g. 'GET', 'POST', etc) + * - **url** – `{string}` – Absolute or relative URL of the resource that is being requested. + * - **params** – `{Object.<string|Object>}` – Map of strings or objects which will be turned + * to `?key1=value1&key2=value2` after the url. If the value is not a string, it will be + * JSONified. + * - **data** – `{string|Object}` – Data to be sent as the request message data. + * - **headers** – `{Object}` – Map of strings or functions which return strings representing + * HTTP headers to send to the server. If the return value of a function is null, the + * header will not be sent. + * - **xsrfHeaderName** – `{string}` – Name of HTTP header to populate with the XSRF token. + * - **xsrfCookieName** – `{string}` – Name of cookie containing the XSRF token. + * - **transformRequest** – + * `{function(data, headersGetter)|Array.<function(data, headersGetter)>}` – + * transform function or an array of such functions. The transform function takes the http + * request body and headers and returns its transformed (typically serialized) version. + * See {@link #overriding-the-default-transformations-per-request Overriding the Default Transformations} + * - **transformResponse** – + * `{function(data, headersGetter)|Array.<function(data, headersGetter)>}` – + * transform function or an array of such functions. The transform function takes the http + * response body and headers and returns its transformed (typically deserialized) version. + * See {@link #overriding-the-default-transformations-per-request Overriding the Default Transformations} + * - **cache** – `{boolean|Cache}` – If true, a default $http cache will be used to cache the + * GET request, otherwise if a cache instance built with + * {@link ng.$cacheFactory $cacheFactory}, this cache will be used for + * caching. + * - **timeout** – `{number|Promise}` – timeout in milliseconds, or {@link ng.$q promise} + * that should abort the request when resolved. + * - **withCredentials** - `{boolean}` - whether to set the `withCredentials` flag on the + * XHR object. See [requests with credentials](https://developer.mozilla.org/docs/Web/HTTP/Access_control_CORS#Requests_with_credentials) + * for more information. + * - **responseType** - `{string}` - see + * [requestType](https://developer.mozilla.org/en-US/docs/DOM/XMLHttpRequest#responseType). + * + * @returns {HttpPromise} Returns a {@link ng.$q promise} object with the + * standard `then` method and two http specific methods: `success` and `error`. The `then` + * method takes two arguments a success and an error callback which will be called with a + * response object. The `success` and `error` methods take a single argument - a function that + * will be called when the request succeeds or fails respectively. The arguments passed into + * these functions are destructured representation of the response object passed into the + * `then` method. The response object has these properties: + * + * - **data** – `{string|Object}` – The response body transformed with the transform + * functions. + * - **status** – `{number}` – HTTP status code of the response. + * - **headers** – `{function([headerName])}` – Header getter function. + * - **config** – `{Object}` – The configuration object that was used to generate the request. + * - **statusText** – `{string}` – HTTP status text of the response. + * + * @property {Array.<Object>} pendingRequests Array of config objects for currently pending + * requests.

This is similar to the native Promise implementation from ES6 Harmony, + * see [MDN](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise). + * + * While the constructor-style use is supported, not all of the supporting methods from ES6 Harmony promises are + * available yet. + * + * It can be used like so: + * + * ```js + * return $q(function(resolve, reject) { + * // perform some asynchronous operation, resolve or reject the promise when appropriate. + * setInterval(function() { + * if (pollStatus > 0) { + * resolve(polledValue); + * } else if (pollStatus < 0) { + * reject(polledValue); + * } else { + * pollStatus = pollAgain(function(value) { + * polledValue = value; + * }); + * } + * }, 10000); + * }). + * then(function(value) { + * // handle success + * }, function(reason) { + * // handle failure + * }); + * ``` + * + * Note: progress/notify callbacks are not currently supported via the ES6-style interface. + * + * However, the more traditional CommonJS-style usage is still available, and documented below. + * + * [The CommonJS Promise proposal](http://wiki.commonjs.org/wiki/Promises) describes a promise as an + * interface for interacting with an object that represents the result of an action that is + * performed asynchronously, and may or may not be finished at any given point in time. + * + * From the perspective of dealing with error handling, deferred and promise APIs are to + * asynchronous programming what `try`, `catch` and `throw` keywords are to synchronous programming. + * + * ```js + * // for the purpose of this example let's assume that variables `$q`, `scope` and `okToGreet` + * // are available in the current lexical scope (they could have been injected or passed in). + * + * function asyncGreet(name) { + * var deferred = $q.defer(); + * + * setTimeout(function() { + * deferred.notify('About to greet ' + name + '.'); + * + * if (okToGreet(name)) { + * deferred.resolve('Hello, ' + name + '!'); + * } else { + * deferred.reject('Greeting ' + name + ' is not allowed.'); + * } + * }, 1000); + * + * return deferred.promise; + * } + * + * var promise = asyncGreet('Robin Hood'); + * promise.then(function(greeting) { + * alert('Success: ' + greeting); + * }, function(reason) { + * alert('Failed: ' + reason); + * }, function(update) { + * alert('Got notification: ' + update); + * }); + * ``` + * + * At first it might not be obvious why this extra complexity is worth the trouble. The payoff + * comes in the way of guarantees that promise and deferred APIs make, see + * https://github.com/kriskowal/uncommonjs/blob/master/promises/specification.md. + * + * Additionally the promise api allows for composition that is very hard to do with the + * traditional callback ([CPS](http://en.wikipedia.org/wiki/Continuation-passing_style)) approach. + * For more on this please see the [Q documentation](https://github.com/kriskowal/q) especially the + * section on serial or parallel joining of promises. + * + * # The Deferred API + * + * A new instance of deferred is constructed by calling `$q.defer()`. + * + * The purpose of the deferred object is to expose the associated Promise instance as well as APIs + * that can be used for signaling the successful or unsuccessful completion, as well as the status + * of the task. + * + * **Methods** + * + * - `resolve(value)` – resolves the derived promise with the `value`. If the value is a rejection + * constructed via `$q.reject`, the promise will be rejected instead. + * - `reject(reason)` – rejects the derived promise with the `reason`. This is equivalent to + * resolving it with a rejection constructed via `$q.reject`. + * - `notify(value)` - provides updates on the status of the promise's execution. This may be called + * multiple times before the promise is either resolved or rejected. + * + * **Properties** + * + * - promise – `{Promise}` – promise object associated with this deferred. + * + * + * # The Promise API + * + * A new promise instance is created when a deferred instance is created and can be retrieved by + * calling `deferred.promise`. + * + * The purpose of the promise object is to allow for interested parties to get access to the result + * of the deferred task when it completes. + * + * **Methods** + * + * - `then(successCallback, errorCallback, notifyCallback)` – regardless of when the promise was or + * will be resolved or rejected, `then` calls one of the success or error callbacks asynchronously + * as soon as the result is available. The callbacks are called with a single argument: the result + * or rejection reason. Additionally, the notify callback may be called zero or more times to + * provide a progress indication, before the promise is resolved or rejected. + * + * This method *returns a new promise* which is resolved or rejected via the return value of the + * `successCallback`, `errorCallback`. It also notifies via the return value of the + * `notifyCallback` method. The promise cannot be resolved or rejected from the notifyCallback + * method. + * + * - `catch(errorCallback)` – shorthand for `promise.then(null, errorCallback)` + * + * - `finally(callback)` – allows you to observe either the fulfillment or rejection of a promise, + * but to do so without modifying the final value. This is useful to release resources or do some + * clean-up that needs to be done whether the promise was rejected or resolved. See the [full + * specification](https://github.com/kriskowal/q/wiki/API-Reference#promisefinallycallback) for + * more information. + * + * Because `finally` is a reserved word in JavaScript and reserved keywords are not supported as + * property names by ES3, you'll need to invoke the method like `promise['finally'](callback)` to + * make your code IE8 and Android 2.x compatible. + * + * # Chaining promises + * + * Because calling the `then` method of a promise returns a new derived promise, it is easily + * possible to create a chain of promises: + * + * ```js + * promiseB = promiseA.then(function(result) { + * return result + 1; + * }); + * + * // promiseB will be resolved immediately after promiseA is resolved and its value + * // will be the result of promiseA incremented by 1 + * ``` + * + * It is possible to create chains of any length and since a promise can be resolved with another + * promise (which will defer its resolution further), it is possible to pause/defer resolution of + * the promises at any point in the chain. This makes it possible to implement powerful APIs like + * $http's response interceptors. + * + * + * # Differences between Kris Kowal's Q and $q + * + * There are two main differences: + * + * - $q is integrated with the {@link ng.$rootScope.Scope} Scope model observation + * mechanism in angular, which means faster propagation of resolution or rejection into your + * models and avoiding unnecessary browser repaints, which would result in flickering UI. + * - Q has many more features than $q, but that comes at a cost of bytes. $q is tiny, but contains + * all the important functionality needed for common async tasks. + * + * # Testing + * + * ```js + * it('should simulate promise', inject(function($q, $rootScope) { + * var deferred = $q.defer(); + * var promise = deferred.promise; + * var resolvedValue; + * + * promise.then(function(value) { resolvedValue = value; }); + * expect(resolvedValue).toBeUndefined(); + * + * // Simulate resolving of promise + * deferred.resolve(123); + * // Note that the 'then' function does not get called synchronously. + * // This is because we want the promise API to always be async, whether or not + * // it got called synchronously or asynchronously. + * expect(resolvedValue).toBeUndefined(); + * + * // Propagate promise resolution to 'then' functions using $apply(). + * $rootScope.$apply(); + * expect(resolvedValue).toEqual(123); + * })); + * ``` + * + * @param {function(function, function)} resolver Function which is responsible for resolving or + * rejecting the newly created promise.

One example of + * such a context is binding arbitrary html controlled by the user via `ng-bind-html`. We refer + * to these contexts as privileged or SCE contexts. + * + * As of version 1.2, Angular ships with SCE enabled by default. + * + * Note: When enabled (the default), IE8 in quirks mode is not supported. In this mode, IE8 allows + * one to execute arbitrary javascript by the use of the expression() syntax. Refer + * <http://blogs.msdn.com/b/ie/archive/2008/10/16/ending-expressions.aspx> to learn more about them. + * You can ensure your document is in standards mode and not quirks mode by adding `<!doctype html>` + * to the top of your HTML document. + * + * SCE assists in writing code in way that (a) is secure by default and (b) makes auditing for + * security vulnerabilities such as XSS, clickjacking, etc. a lot easier. + * + * Here's an example of a binding in a privileged context: + * + * ``` + * <input ng-model="userHtml"> + * <div ng-bind-html="userHtml"></div> + * ``` + * + * Notice that `ng-bind-html` is bound to `userHtml` controlled by the user. With SCE + * disabled, this application allows the user to render arbitrary HTML into the DIV. + * In a more realistic example, one may be rendering user comments, blog articles, etc. via + * bindings. (HTML is just one example of a context where rendering user controlled input creates + * security vulnerabilities.) + * + * For the case of HTML, you might use a library, either on the client side, or on the server side, + * to sanitize unsafe HTML before binding to the value and rendering it in the document. + * + * How would you ensure that every place that used these types of bindings was bound to a value that + * was sanitized by your library (or returned as safe for rendering by your server?) How can you + * ensure that you didn't accidentally delete the line that sanitized the value, or renamed some + * properties/fields and forgot to update the binding to the sanitized value? + * + * To be secure by default, you want to ensure that any such bindings are disallowed unless you can + * determine that something explicitly says it's safe to use a value for binding in that + * context. You can then audit your code (a simple grep would do) to ensure that this is only done + * for those values that you can easily tell are safe - because they were received from your server, + * sanitized by your library, etc. You can organize your codebase to help with this - perhaps + * allowing only the files in a specific directory to do this. Ensuring that the internal API + * exposed by that code doesn't markup arbitrary values as safe then becomes a more manageable task. + * + * In the case of AngularJS' SCE service, one uses {@link ng.$sce#trustAs $sce.trustAs} + * (and shorthand methods such as {@link ng.$sce#trustAsHtml $sce.trustAsHtml}, etc.) to + * obtain values that will be accepted by SCE / privileged contexts. + * + * + * ## How does it work? + * + * In privileged contexts, directives and code will bind to the result of {@link ng.$sce#getTrusted + * $sce.getTrusted(context, value)} rather than to the value directly. Directives use {@link + * ng.$sce#parse $sce.parseAs} rather than `$parse` to watch attribute bindings, which performs the + * {@link ng.$sce#getTrusted $sce.getTrusted} behind the scenes on non-constant literals. + * + * As an example, {@link ng.directive:ngBindHtml ngBindHtml} uses {@link + * ng.$sce#parseAsHtml $sce.parseAsHtml(binding expression)}. Here's the actual code (slightly + * simplified): + * + * ``` + * var ngBindHtmlDirective = ['$sce', function($sce) { + * return function(scope, element, attr) { + * scope.$watch($sce.parseAsHtml(attr.ngBindHtml), function(value) { + * element.html(value || ''); + * }); + * }; + * }]; + * ``` + * + * ## Impact on loading templates + * + * This applies both to the {@link ng.directive:ngInclude `ng-include`} directive as well as + * `templateUrl`'s specified by {@link guide/directive directives}. + * + * By default, Angular only loads templates from the same domain and protocol as the application + * document. This is done by calling {@link ng.$sce#getTrustedResourceUrl + * $sce.getTrustedResourceUrl} on the template URL. To load templates from other domains and/or + * protocols, you may either either {@link ng.$sceDelegateProvider#resourceUrlWhitelist whitelist + * them} or {@link ng.$sce#trustAsResourceUrl wrap it} into a trusted value. + * + * *Please note*: + * The browser's + * [Same Origin Policy](https://code.google.com/p/browsersec/wiki/Part2#Same-origin_policy_for_XMLHttpRequest) + * and [Cross-Origin Resource Sharing (CORS)](http://www.w3.org/TR/cors/) + * policy apply in addition to this and may further restrict whether the template is successfully + * loaded. This means that without the right CORS policy, loading templates from a different domain + * won't work on all browsers. Also, loading templates from `file://` URL does not work on some + * browsers. + * + * ## This feels like too much overhead + * + * It's important to remember that SCE only applies to interpolation expressions. + * + * If your expressions are constant literals, they're automatically trusted and you don't need to + * call `$sce.trustAs` on them (remember to include the `ngSanitize` module) (e.g. + * `<div ng-bind-html="'<b>implicitly trusted</b>'"></div>`) just works. + * + * Additionally, `a[href]` and `img[src]` automatically sanitize their URLs and do not pass them + * through {@link ng.$sce#getTrusted $sce.getTrusted}. SCE doesn't play a role here. + * + * The included {@link ng.$sceDelegate $sceDelegate} comes with sane defaults to allow you to load + * templates in `ng-include` from your application's domain without having to even know about SCE. + * It blocks loading templates from other domains or loading templates over http from an https + * served document. You can change these by setting your own custom {@link + * ng.$sceDelegateProvider#resourceUrlWhitelist whitelists} and {@link + * ng.$sceDelegateProvider#resourceUrlBlacklist blacklists} for matching such URLs. + * + * This significantly reduces the overhead. It is far easier to pay the small overhead and have an + * application that's secure and can be audited to verify that with much more ease than bolting + * security onto an application later. + * + * <a name="contexts"></a> + * ## What trusted context types are supported? + * + * | Context | Notes | + * |---------------------|----------------| + * | `$sce.HTML` | For HTML that's safe to source into the application. The {@link ng.directive:ngBindHtml ngBindHtml} directive uses this context for bindings. If an unsafe value is encountered and the {@link ngSanitize $sanitize} module is present this will sanitize the value instead of throwing an error. | + * | `$sce.CSS` | For CSS that's safe to source into the application. Currently unused. Feel free to use it in your own directives. | + * | `$sce.URL` | For URLs that are safe to follow as links. Currently unused (`<a href=` and `<img src=` sanitize their urls and don't constitute an SCE context. | + * | `$sce.RESOURCE_URL` | For URLs that are not only safe to follow as links, but whose contents are also safe to include in your application. Examples include `ng-include`, `src` / `ngSrc` bindings for tags other than `IMG` (e.g. `IFRAME`, `OBJECT`, etc.) <br><br>Note that `$sce.RESOURCE_URL` makes a stronger statement about the URL than `$sce.URL` does and therefore contexts requiring values trusted for `$sce.RESOURCE_URL` can be used anywhere that values trusted for `$sce.URL` are required. | + * | `$sce.JS` | For JavaScript that is safe to execute in your application's context. Currently unused. Feel free to use it in your own directives. | + * + * ## Format of items in {@link ng.$sceDelegateProvider#resourceUrlWhitelist resourceUrlWhitelist}/{@link ng.$sceDelegateProvider#resourceUrlBlacklist Blacklist} <a name="resourceUrlPatternItem"></a> + * + * Each element in these arrays must be one of the following: + * + * - **'self'** + * - The special **string**, `'self'`, can be used to match against all URLs of the **same + * domain** as the application document using the **same protocol**. + * - **String** (except the special value `'self'`) + * - The string is matched against the full *normalized / absolute URL* of the resource + * being tested (substring matches are not good enough.) + * - There are exactly **two wildcard sequences** - `*` and `**`. All other characters + * match themselves. + * - `*`: matches zero or more occurrences of any character other than one of the following 6 + * characters: '`:`', '`/`', '`.`', '`?`', '`&`' and ';'. It's a useful wildcard for use + * in a whitelist. + * - `**`: matches zero or more occurrences of *any* character. As such, it's not + * not appropriate to use in for a scheme, domain, etc. as it would match too much. (e.g. + * http://**.example.com/ would match http://evil.com/?ignore=.example.com/ and that might + * not have been the intention.) Its usage at the very end of the path is ok. (e.g. + * http://foo.example.com/templates/**). + * - **RegExp** (*see caveat below*) + * - *Caveat*: While regular expressions are powerful and offer great flexibility, their syntax + * (and all the inevitable escaping) makes them *harder to maintain*. It's easy to + * accidentally introduce a bug when one updates a complex expression (imho, all regexes should + * have good test coverage.). For instance, the use of `.` in the regex is correct only in a + * small number of cases. A `.` character in the regex used when matching the scheme or a + * subdomain could be matched against a `:` or literal `.` that was likely not intended. It + * is highly recommended to use the string patterns and only fall back to regular expressions + * if they as a last resort. + * - The regular expression must be an instance of RegExp (i.e. not a string.) It is + * matched against the **entire** *normalized / absolute URL* of the resource being tested + * (even when the RegExp did not have the `^` and `$` codes.) In addition, any flags + * present on the RegExp (such as multiline, global, ignoreCase) are ignored. + * - If you are generating your JavaScript from some other templating engine (not + * recommended, e.g. in issue [#4006](https://github.com/angular/angular.js/issues/4006)), + * remember to escape your regular expression (and be aware that you might need more than + * one level of escaping depending on your templating engine and the way you interpolated + * the value.) Do make use of your platform's escaping mechanism as it might be good + * enough before coding your own. e.g. Ruby has + * [Regexp.escape(str)](http://www.ruby-doc.org/core-2.0.0/Regexp.html#method-c-escape) + * and Python has [re.escape](http://docs.python.org/library/re.html#re.escape). + * Javascript lacks a similar built in function for escaping. Take a look at Google + * Closure library's [goog.string.regExpEscape(s)]( + * http://docs.closure-library.googlecode.com/git/closure_goog_string_string.js.source.html#line962). + * + * Refer {@link ng.$sceDelegateProvider $sceDelegateProvider} for an example. + * + * ## Show me an example using SCE. + * + * <example module="mySceApp" deps="angular-sanitize.js"> + * <file name="index.html"> + * <div ng-controller="AppController as myCtrl"> + * <i ng-bind-html="myCtrl.explicitlyTrustedHtml" id="explicitlyTrustedHtml"></i><br><br> + * <b>User comments</b><br> + * By default, HTML that isn't explicitly trusted (e.g. Alice's comment) is sanitized when + * $sanitize is available.

Normalizing means that a relative + * URL will be resolved into an absolute URL in the context of the application document. + * Parsing means that the anchor node's host, hostname, protocol, port, pathname and related + * properties are all populated to reflect the normalized URL. This approach has wide + * compatibility - Safari 1+, Mozilla 1+, Opera 7+,e etc. See + * http://www.aptana.com/reference/html/api/HTMLAnchorElement.html + * + * Implementation Notes for IE + * --------------------------- + * IE >= 8 and <= 10 normalizes the URL when assigned to the anchor node similar to the other + * browsers. However, the parsed components will not be set if the URL assigned did not specify + * them. (e.g. if you assign a.href = "foo", then a.protocol, a.host, etc. will be empty.) We + * work around that by performing the parsing in a 2nd step by taking a previously normalized + * URL (e.g. by assigning to a.href) and assigning it a.href again. This correctly populates the + * properties such as protocol, hostname, port, etc. + * + * IE7 does not normalize the URL when assigned to an anchor node. (Apparently, it does, if one + * uses the inner HTML approach to assign the URL as part of an HTML snippet - + * http://stackoverflow.com/a/472729) However, setting img[src] does normalize the URL. + * Unfortunately, setting img[src] to something like "javascript:foo" on IE throws an exception. + * Since the primary usage for normalizing URLs is to sanitize such URLs, we can't use that + * method and IE < 8 is unsupported. + * + * References: + * http://developer.mozilla.org/en-US/docs/Web/API/HTMLAnchorElement + * http://www.aptana.com/reference/html/api/HTMLAnchorElement.html + * http://url.spec.whatwg.org/#urlutils + * https://github.com/angular/angular.js/pull/2902 + * http://james.padolsey.com/javascript/parsing-urls-with-the-dom/ + * + * @kind function + * @param {string} url The URL to be parsed. + * @description Normalizes and parses a URL. + * @returns {object} Returns the normalized URL as a dictionary. + * + * | member name | Description | + * |---------------|----------------| + * | href | A normalized version of the provided URL if it was not an absolute URL | + * | protocol | The protocol including the trailing colon | + * | host | The host and port (if the port is non-default) of the normalizedUrl | + * | search | The search params, minus the question mark | + * | hash | The hash string, minus the hash symbol + * | hostname | The hostname + * | port | The port, without ":" + * | pathname | The pathname, beginning with "/" + * + */ +function urlResolve(url, base) { + var href = url; + + if (msie) { + // Normalize before parse.

This means that the outer form is valid when all of the child + * forms are valid as well. However, browsers do not allow nesting of `<form>` elements, so + * Angular provides the {@link ng.directive:ngForm `ngForm`} directive which behaves identically to + * `<form>` but can be nested. This allows you to have nested forms, which is very useful when + * using Angular validation directives in forms that are dynamically generated using the + * {@link ng.directive:ngRepeat `ngRepeat`} directive. Since you cannot dynamically generate the `name` + * attribute of input elements using interpolation, you have to wrap each set of repeated inputs in an + * `ngForm` directive and nest these in an outer `form` element. + * + * + * # CSS classes + * - `ng-valid` is set if the form is valid. + * - `ng-invalid` is set if the form is invalid. + * - `ng-pristine` is set if the form is pristine. + * - `ng-dirty` is set if the form is dirty. + * - `ng-submitted` is set if the form was submitted. + * + * Keep in mind that ngAnimate can detect each of these classes when added and removed. + * + * + * # Submitting a form and preventing the default action + * + * Since the role of forms in client-side Angular applications is different than in classical + * roundtrip apps, it is desirable for the browser not to translate the form submission into a full + * page reload that sends the data to the server. Instead some javascript logic should be triggered + * to handle the form submission in an application-specific way. + * + * For this reason, Angular prevents the default action (form submission to the server) unless the + * `<form>` element has an `action` attribute specified. + * + * You can use one of the following two ways to specify what javascript method should be called when + * a form is submitted: + * + * - {@link ng.directive:ngSubmit ngSubmit} directive on the form element + * - {@link ng.directive:ngClick ngClick} directive on the first + * button or input field of type submit (input[type=submit]) + * + * To prevent double execution of the handler, use only one of the {@link ng.directive:ngSubmit ngSubmit} + * or {@link ng.directive:ngClick ngClick} directives. + * This is because of the following form submission rules in the HTML specification: + * + * - If a form has only one input field then hitting enter in this field triggers form submit + * (`ngSubmit`) + * - if a form has 2+ input fields and no buttons or input[type=submit] then hitting enter + * doesn't trigger submit + * - if a form has one or more input fields and one or more buttons or input[type=submit] then + * hitting enter in any of the input fields will trigger the click handler on the *first* button or + * input[type=submit] (`ngClick`) *and* a submit handler on the enclosing form (`ngSubmit`) + * + * Any pending `ngModelOptions` changes will take place immediately when an enclosing form is + * submitted. Note that `ngClick` events will occur before the model is updated. Use `ngSubmit` + * to have access to the updated model. + * + * ## Animation Hooks + * + * Animations in ngForm are triggered when any of the associated CSS classes are added and removed. + * These classes are: `.ng-pristine`, `.ng-dirty`, `.ng-invalid` and `.ng-valid` as well as any + * other validations that are performed within the form. Animations in ngForm are similar to how + * they work in ngClass and animations can be hooked into using CSS transitions, keyframes as well + * as JS animations. + * + * The following example shows a simple way to utilize CSS transitions to style a form element + * that has been rendered as invalid after it has been validated: + * + * <pre> + * //be sure to include ngAnimate as a module to hook into more + * //advanced animations + * .my-form { + * transition:0.5s linear all; + * background: white; + * } + * .my-form.ng-invalid { + * background: red; + * color:white; + * } + * </pre> + * + * @example + <example deps="angular-animate.js" animations="true" fixBase="true" module="formExample"> + <file name="index.html"> + <script> + angular.module('formExample', []) + .controller('FormController', ['$scope', function($scope) { + $scope.userType = 'guest'; + }]); + </script> + <style> + .my-form { + -webkit-transition:all linear 0.5s; + transition:all linear 0.5s; + background: transparent; + } + .my-form.ng-invalid { + background: red; + } + </style> + <form name="myForm" ng-controller="FormController" class="my-form"> + userType: <input name="input" ng-model="userType" required> + <span class="error" ng-show="myForm.input.$error.required">Required!</span><br> + <tt>userType = {{userType}}</tt><br> + <tt>myForm.input.$valid = {{myForm.input.$valid}}</tt><br> + <tt>myForm.input.$error = {{myForm.input.$error}}</tt><br> + <tt>myForm.$valid = {{myForm.$valid}}</tt><br> + <tt>myForm.$error.required = {{!!myForm.$error.required}}</tt><br> + </form> + </file> + <file name="protractor.js" type="protractor"> + it('should initialize to model', function() { + var userType = element(by.binding('userType')); + var valid = element(by.binding('myForm.input.$valid')); + + expect(userType.getText()).toContain('guest'); + expect(valid.getText()).toContain('true'); + }); + + it('should be invalid if empty', function() { + var userType = element(by.binding('userType')); + var valid = element(by.binding('myForm.input.$valid')); + var userInput = element(by.model('userType')); + + userInput.clear(); + userInput.sendKeys(''); + + expect(userType.getText()).toEqual('userType ='); + expect(valid.getText()).toContain('false'); + }); + </file> + </example> + * + * @param {string=} name Name of the form.

This means that if you update the model you + * should also invoke {@link ngModel.NgModelController `$rollbackViewValue`} on the relevant input field in + * order to make sure it is synchronized with the model and that any debounced action is canceled. + * + * The easiest way to reference the control's {@link ngModel.NgModelController `$rollbackViewValue`} + * method is by making sure the input is placed inside a form that has a `name` attribute. This is + * important because `form` controllers are published to the related scope under the name in their + * `name` attribute. + * + * Any pending changes will take place immediately when an enclosing form is submitted via the + * `submit` event. Note that `ngClick` events will occur before the model is updated. Use `ngSubmit` + * to have access to the updated model. + * + * @param {Object} ngModelOptions options to apply to the current model. Valid keys are: + * - `updateOn`: string specifying which event should be the input bound to. You can set several + * events using an space delimited list. There is a special event called `default` that + * matches the default events belonging of the control. + * - `debounce`: integer value which contains the debounce model update value in milliseconds. A + * value of 0 triggers an immediate update. If an object is supplied instead, you can specify a + * custom value for each event. For example: + * `ng-model-options="{ updateOn: 'default blur', debounce: {'default': 500, 'blur': 0} }"` + * - `allowInvalid`: boolean value which indicates that the model can be set with values that did + * not validate correctly instead of the default behavior of setting the model to undefined. + * - `getterSetter`: boolean value which determines whether or not to treat functions bound to + `ngModel` as getters/setters. + * - `timezone`: Defines the timezone to be used to read/write the `Date` instance in the model for + * `<input type="date">`, `<input type="time">`, ... . Right now, the only supported value is `'UTC'`, + * otherwise the default timezone of the browser will be used. + * + * @example + + The following example shows how to override immediate updates.

A common mistake is to declare the controller + * again using `ng-controller` in the template itself.

Adding, removing, clearing, and + * greeting are methods declared on the controller (see source tab). These methods can + * easily be called from the angular markup. Any changes to the data are automatically reflected + * in the View without the need for a manual update. + * + * Two different declaration styles are included below: + * + * * one binds methods and properties directly onto the controller using `this`: + * `ng-controller="SettingsController1 as settings"` + * * one injects `$scope` into the controller: + * `ng-controller="SettingsController2"` + * + * The second option is more common in the Angular community, and is generally used in boilerplates + * and in this guide. However, there are advantages to binding properties directly to the controller + * and avoiding scope. + * + * * Using `controller as` makes it obvious which controller you are accessing in the template when + * multiple controllers apply to an element. + * * If you are writing your controllers as classes you have easier access to the properties and + * methods, which will appear on the scope, from inside the controller code. + * * Since there is always a `.` in the bindings, you don't have to worry about prototypal + * inheritance masking primitives. + * + * This example demonstrates the `controller as` syntax. + * + * <example name="ngControllerAs" module="controllerAsExample"> + * <file name="index.html"> + * <div id="ctrl-as-exmpl" ng-controller="SettingsController1 as settings"> + * Name: <input type="text" ng-model="settings.name"/> + * [ <a href="" ng-click="settings.greet()">greet</a> ]<br/> + * Contact: + * <ul> + * <li ng-repeat="contact in settings.contacts"> + * <select ng-model="contact.type"> + * <option>phone</option> + * <option>email</option> + * </select> + * <input type="text" ng-model="contact.value"/> + * [ <a href="" ng-click="settings.clearContact(contact)">clear</a> + * | <a href="" ng-click="settings.removeContact(contact)">X</a> ] + * </li> + * <li>[ <a href="" ng-click="settings.addContact()">add</a> ]</li> + * </ul> + * </div> + * </file> + * <file name="app.js"> + * angular.module('controllerAsExample', []) + * .controller('SettingsController1', SettingsController1);

If the expression assigned to `ngIf` evaluates to a false + * value then the element is removed from the DOM, otherwise a clone of the + * element is reinserted into the DOM. + * + * `ngIf` differs from `ngShow` and `ngHide` in that `ngIf` completely removes and recreates the + * element in the DOM rather than changing its visibility via the `display` css property. A common + * case when this difference is significant is when using css selectors that rely on an element's + * position within the DOM, such as the `:first-child` or `:last-child` pseudo-classes. + * + * Note that when an element is removed using `ngIf` its scope is destroyed and a new scope + * is created when the element is restored. The scope created within `ngIf` inherits from + * its parent scope using + * [prototypal inheritance](https://github.com/angular/angular.js/wiki/The-Nuances-of-Scope-Prototypal-Inheritance). + * An important implication of this is if `ngModel` is used within `ngIf` to bind to + * a javascript primitive defined in the parent scope. In this case any modifications made to the + * variable within the child scope will override (hide) the value in the parent scope. + * + * Also, `ngIf` recreates elements using their compiled state. An example of this behavior + * is if an element's class attribute is directly modified after it's compiled, using something like + * jQuery's `.addClass()` method, and the element is later removed. When `ngIf` recreates the element + * the added class will be lost because the original compiled state is used to regenerate the element. + * + * Additionally, you can provide animations via the `ngAnimate` module to animate the `enter` + * and `leave` effects. + * + * @animations + * enter - happens just after the ngIf contents change and a new DOM element is created and injected into the ngIf container + * leave - happens just before the ngIf contents are removed from the DOM + * + * @element ANY + * @scope + * @priority 600 + * @param {expression} ngIf If the {@link guide/expression expression} is falsy then + * the element is removed from the DOM tree.

You configure ngPluralize directive + * by specifying the mappings between + * [plural categories](http://unicode.org/repos/cldr-tmp/trunk/diff/supplemental/language_plural_rules.html) + * and the strings to be displayed. + * + * # Plural categories and explicit number rules + * There are two + * [plural categories](http://unicode.org/repos/cldr-tmp/trunk/diff/supplemental/language_plural_rules.html) + * in Angular's default en-US locale: "one" and "other". + * + * While a plural category may match many numbers (for example, in en-US locale, "other" can match + * any number that is not 1), an explicit number rule can only match one number. For example, the + * explicit number rule for "3" matches the number 3. There are examples of plural categories + * and explicit number rules throughout the rest of this documentation. + * + * # Configuring ngPluralize + * You configure ngPluralize by providing 2 attributes: `count` and `when`. + * You can also provide an optional attribute, `offset`. + * + * The value of the `count` attribute can be either a string or an {@link guide/expression + * Angular expression}; these are evaluated on the current scope for its bound value. + * + * The `when` attribute specifies the mappings between plural categories and the actual + * string to be displayed. The value of the attribute should be a JSON object. + * + * The following example shows how to configure ngPluralize: + * + * ```html + * <ng-pluralize count="personCount" + when="{'0': 'Nobody is viewing.', + * 'one': '1 person is viewing.', + * 'other': '{} people are viewing.'}"> + * </ng-pluralize> + *``` + * + * In the example, `"0: Nobody is viewing."` is an explicit number rule. If you did not + * specify this rule, 0 would be matched to the "other" category and "0 people are viewing" + * would be shown instead of "Nobody is viewing". You can specify an explicit number rule for + * other numbers, for example 12, so that instead of showing "12 people are viewing", you can + * show "a dozen people are viewing". + * + * You can use a set of closed braces (`{}`) as a placeholder for the number that you want substituted + * into pluralized strings. In the previous example, Angular will replace `{}` with + * <span ng-non-bindable>`{{personCount}}`</span>. The closed braces `{}` is a placeholder + * for <span ng-non-bindable>{{numberExpression}}</span>. + * + * # Configuring ngPluralize with offset + * The `offset` attribute allows further customization of pluralized text, which can result in + * a better user experience. For example, instead of the message "4 people are viewing this document", + * you might display "John, Kate and 2 others are viewing this document". + * The offset attribute allows you to offset a number by any desired value. + * Let's take a look at an example: + * + * ```html + * <ng-pluralize count="personCount" offset=2 + * when="{'0': 'Nobody is viewing.', + * '1': '{{person1}} is viewing.', + * '2': '{{person1}} and {{person2}} are viewing.', + * 'one': '{{person1}}, {{person2}} and one other person are viewing.', + * 'other': '{{person1}}, {{person2}} and {} other people are viewing.'}"> + * </ng-pluralize> + * ``` + * + * Notice that we are still using two plural categories(one, other), but we added + * three explicit number rules 0, 1 and 2. + * When one person, perhaps John, views the document, "John is viewing" will be shown. + * When three people view the document, no explicit number rule is found, so + * an offset of 2 is taken off 3, and Angular uses 1 to decide the plural category. + * In this case, plural category 'one' is matched and "John, Mary and one other person are viewing" + * is shown. + * + * Note that when you specify offsets, you must provide explicit number rules for + * numbers from 0 up to and including the offset. If you use an offset of 3, for example, + * you must provide explicit number rules for 0, 1, 2 and 3. You must also provide plural strings for + * plural categories "one" and "other". + * + * @param {string|expression} count The variable to be bound to. + * @param {string} when The mapping between plural category to its corresponding strings. + * @param {number=} offset Offset to deduct from the total number. + * + * @example + <example module="pluralizeExample"> + <file name="index.html"> + <script> + angular.module('pluralizeExample', []) + .controller('ExampleController', ['$scope', function($scope) { + $scope.person1 = 'Igor'; + $scope.person2 = 'Misko'; + $scope.personCount = 1; + }]); + </script> + <div ng-controller="ExampleController"> + Person 1:<input type="text" ng-model="person1" value="Igor" /><br/> + Person 2:<input type="text" ng-model="person2" value="Misko" /><br/> + Number of People:<input type="text" ng-model="personCount" value="1" /><br/> + + <!--- Example with simple pluralization rules for en locale ---> + Without Offset: + <ng-pluralize count="personCount" + when="{'0': 'Nobody is viewing.', + 'one': '1 person is viewing.', + 'other': '{} people are viewing.'}"> + </ng-pluralize><br> + + <!--- Example with offset ---> + With Offset(2): + <ng-pluralize count="personCount" offset=2 + when="{'0': 'Nobody is viewing.', + '1': '{{person1}} is viewing.', + '2': '{{person1}} and {{person2}} are viewing.', + 'one': '{{person1}}, {{person2}} and one other person are viewing.', + 'other': '{{person1}}, {{person2}} and {} other people are viewing.'}"> + </ng-pluralize> + </div> + </file> + <file name="protractor.js" type="protractor"> + it('should show correct pluralized string', function() { + var withoutOffset = element.all(by.css('ng-pluralize')).get(0); + var withOffset = element.all(by.css('ng-pluralize')).get(1); + var countInput = element(by.model('personCount')); + + expect(withoutOffset.getText()).toEqual('1 person is viewing.'); + expect(withOffset.getText()).toEqual('Igor is viewing.'); + + countInput.clear(); + countInput.sendKeys('0'); + + expect(withoutOffset.getText()).toEqual('Nobody is viewing.'); + expect(withOffset.getText()).toEqual('Nobody is viewing.'); + + countInput.clear(); + countInput.sendKeys('2'); + + expect(withoutOffset.getText()).toEqual('2 people are viewing.'); + expect(withOffset.getText()).toEqual('Igor and Misko are viewing.'); + + countInput.clear(); + countInput.sendKeys('3'); + + expect(withoutOffset.getText()).toEqual('3 people are viewing.'); + expect(withOffset.getText()).toEqual('Igor, Misko and one other person are viewing.'); + + countInput.clear(); + countInput.sendKeys('4'); + + expect(withoutOffset.getText()).toEqual('4 people are viewing.'); + expect(withOffset.getText()).toEqual('Igor, Misko and 2 other people are viewing.'); + }); + it('should show data-bound names', function() { + var withOffset = element.all(by.css('ng-pluralize')).get(1); + var personCount = element(by.model('personCount')); + var person1 = element(by.model('person1')); + var person2 = element(by.model('person2')); + personCount.clear(); + personCount.sendKeys('4'); + person1.clear(); + person1.sendKeys('Di'); + person2.clear(); + person2.sendKeys('Vojta'); + expect(withOffset.getText()).toEqual('Di, Vojta and 2 other people are viewing.'); + }); + </file> + </example> + */ +var ngPluralizeDirective = ['$locale', '$interpolate', function($locale, $interpolate) { + var BRACE = /{}/g; + return { + restrict: 'EA', + link: function(scope, element, attr) { + var numberExp = attr.count, + whenExp = attr.$attr.when && element.attr(attr.$attr.when), // we have {{}} in attrs + offset = attr.offset || 0, + whens = scope.$eval(whenExp) || {}, + whensExpFns = {}, + startSymbol = $interpolate.startSymbol(), + endSymbol = $interpolate.endSymbol(), + isWhen = /^when(Minus)?(.+)$/; + + forEach(attr, function(expression, attributeName) { + if (isWhen.test(attributeName)) { + whens[lowercase(attributeName.replace('when', '').replace('Minus', '-'))] = + element.attr(attr.$attr[attributeName]); + } + }); + forEach(whens, function(expression, key) { + whensExpFns[key] = + $interpolate(expression.replace(BRACE, startSymbol + numberExp + '-' + + offset + endSymbol)); + }); + + scope.$watch(function ngPluralizeWatch() { + var value = parseFloat(scope.$eval(numberExp)); + + if (!isNaN(value)) { + //if explicit number rule such as 1, 2, 3... is defined, just use it.

These + * formats are currently supported: + * + * * `variable in expression` – where variable is the user defined loop variable and `expression` + * is a scope expression giving the collection to enumerate. + * + * For example: `album in artist.albums`. + * + * * `(key, value) in expression` – where `key` and `value` can be any user defined identifiers, + * and `expression` is the scope expression giving the collection to enumerate. + * + * For example: `(name, age) in {'adam':10, 'amalie':12}`. + * + * * `variable in expression track by tracking_expression` – You can also provide an optional tracking function + * which can be used to associate the objects in the collection with the DOM elements. If no tracking function + * is specified the ng-repeat associates elements by identity in the collection. It is an error to have + * more than one tracking function to resolve to the same key. (This would mean that two distinct objects are + * mapped to the same DOM element, which is not possible.) Filters should be applied to the expression, + * before specifying a tracking expression. + * + * For example: `item in items` is equivalent to `item in items track by $id(item)`. This implies that the DOM elements + * will be associated by item identity in the array. + * + * * `variable in expression as alias_expression` – You can also provide an optional alias expression which will then store the + * intermediate results of the repeater after the filters have been applied. Typically this is used to render a special message + * when a filter is active on the repeater, but the filtered result set is empty. + * + * For example: `item in items | filter:x as results` will store the fragment of the repeated items as `results`, but only after + * the items have been processed through the filter. + * + * For example: `item in items track by $id(item)`. A built in `$id()` function can be used to assign a unique + * `$$hashKey` property to each item in the array.

Moving the same object in array would move the DOM + * element in the same way in the DOM. + * + * For example: `item in items track by item.id` is a typical pattern when the items come from the database. In this + * case the object identity does not matter. Two objects are considered equivalent as long as their `id` + * property is same. + * + * For example: `item in items | filter:searchText track by item.id` is a pattern that might be used to apply a filter + * to items in conjunction with a tracking expression. + * + * @example + * This example initializes the scope to a list of names and + * then uses `ngRepeat` to display every person: + <example module="ngAnimate" deps="angular-animate.js" animations="true"> + <file name="index.html"> + <div ng-init="friends = [ + {name:'John', age:25, gender:'boy'}, + {name:'Jessie', age:30, gender:'girl'}, + {name:'Johanna', age:28, gender:'girl'}, + {name:'Joy', age:15, gender:'girl'}, + {name:'Mary', age:28, gender:'girl'}, + {name:'Peter', age:95, gender:'boy'}, + {name:'Sebastian', age:50, gender:'boy'}, + {name:'Erika', age:27, gender:'girl'}, + {name:'Patrick', age:40, gender:'boy'}, + {name:'Samantha', age:60, gender:'girl'} + ]"> + I have {{friends.length}} friends.
