This blocking feature can be overridden by + * placing the `ng-animate-children` attribute on a parent container tag. + * + * ```html + * <div class="slide-animation" ng-if="on" ng-animate-children> + * <div class="fade-animation" ng-if="on"> + * <div class="explode-animation" ng-if="on"> + * ... + * </div> + * </div> + * </div> + * ``` + * + * When the `on` expression value changes and an animation is triggered then each of the elements within + * will all animate without the block being applied to child elements. + * + * ## Are animations run when the application starts? + * No they are not. When an application is bootstrapped Angular will disable animations from running to avoid + * a frenzy of animations from being triggered as soon as the browser has rendered the screen. For this to work, + * Angular will wait for two digest cycles until enabling animations. From there on, any animation-triggering + * layout changes in the application will trigger animations as normal. + * + * In addition, upon bootstrap, if the routing system or any directives or load remote data (via $http) then Angular + * will automatically extend the wait time to enable animations once **all** of the outbound HTTP requests + * are complete. + * + * <h2>CSS-defined Animations</h2> + * The animate service will automatically apply two CSS classes to the animated element and these two CSS classes + * are designed to contain the start and end CSS styling. Both CSS transitions and keyframe animations are supported + * and can be used to play along with this naming structure. + * + * The following code below demonstrates how to perform animations using **CSS transitions** with Angular: + * + * ```html + * <style type="text/css"> + * /* + * The animate class is apart of the element and the ng-enter class + * is attached to the element once the enter animation event is triggered + * */ + * .reveal-animation.ng-enter { + * -webkit-transition: 1s linear all; /* Safari/Chrome */ + * transition: 1s linear all; /* All other modern browsers and IE10+ */ + * + * /* The animation preparation code */ + * opacity: 0; + * } + * + * /* + * Keep in mind that you want to combine both CSS + * classes together to avoid any CSS-specificity + * conflicts + * */ + * .reveal-animation.ng-enter.ng-enter-active { + * /* The animation code itself */ + * opacity: 1; + * } + * </style> + * + * <div class="view-container"> + * <div ng-view class="reveal-animation"></div> + * </div> + * ``` + * + * The following code below demonstrates how to perform animations using **CSS animations** with Angular: + * + * ```html + * <style type="text/css"> + * .reveal-animation.ng-enter { + * -webkit-animation: enter_sequence 1s linear; /* Safari/Chrome */ + * animation: enter_sequence 1s linear; /* IE10+ and Future Browsers */ + * } + * @-webkit-keyframes enter_sequence { + * from { opacity:0; } + * to { opacity:1; } + * } + * @keyframes enter_sequence { + * from { opacity:0; } + * to { opacity:1; } + * } + * </style> + * + * <div class="view-container"> + * <div ng-view class="reveal-animation"></div> + * </div> + * ``` + * + * Both CSS3 animations and transitions can be used together and the animate service will figure out the correct duration and delay timing. + * + * Upon DOM mutation, the event class is added first (something like `ng-enter`), then the browser prepares itself to add + * the active class (in this case `ng-enter-active`) which then triggers the animation. The animation module will automatically + * detect the CSS code to determine when the animation ends. Once the animation is over then both CSS classes will be + * removed from the DOM. If a browser does not support CSS transitions or CSS animations then the animation will start and end + * immediately resulting in a DOM element that is at its final state. This final state is when the DOM element + * has no CSS transition/animation classes applied to it. + * + * ### Structural transition animations + * + * Structural transitions (such as enter, leave and move) will always apply a `0s none` transition + * value to force the browser into rendering the styles defined in the setup (.ng-enter, .ng-leave + * or .ng-move) class. This means that any active transition animations operating on the element + * will be cut off to make way for the enter, leave or move animation. + * + * ### Class-based transition animations + * + * Class-based transitions refer to transition animations that are triggered when a CSS class is + * added to or removed from the element (via `$animate.addClass`, `$animate.removeClass`, + * `$animate.setClass`, or by directives such as `ngClass`, `ngModel` and `form`). + * They are different when compared to structural animations since they **do not cancel existing + * animations** nor do they **block successive transitions** from rendering on the same element. + * This distinction allows for **multiple class-based transitions** to be performed on the same element. + * + * In addition to ngAnimate supporting the default (natural) functionality of class-based transition + * animations, ngAnimate also decorates the element with starting and ending CSS classes to aid the + * developer in further styling the element throughout the transition animation. Earlier versions + * of ngAnimate may have caused natural CSS transitions to break and not render properly due to + * $animate temporarily blocking transitions using `0s none` in order to allow the setup CSS class + * (the `-add` or `-remove` class) to be applied without triggering an animation. However, as of + * **version 1.3**, this workaround has been removed with ngAnimate and all non-ngAnimate CSS + * class transitions are compatible with ngAnimate. + * + * There is, however, one special case when dealing with class-based transitions in ngAnimate. + * When rendering class-based transitions that make use of the setup and active CSS classes + * (e.g. `.fade-add` and `.fade-add-active` for when `.fade` is added) be sure to define + * the transition value **on the active CSS class** and not the setup class. + * + * ```css + * .fade-add { + * /* remember to place a 0s transition here + * to ensure that the styles are applied instantly + * even if the element already has a transition style */ + * transition:0s linear all; + * + * /* starting CSS styles */ + * opacity:1; + * } + * .fade-add.fade-add-active { + * /* this will be the length of the animation */ + * transition:1s linear all; + * opacity:0; + * } + * ``` + * + * The setup CSS class (in this case `.fade-add`) also has a transition style property, however, it + * has a duration of zero. This may not be required, however, incase the browser is unable to render + * the styling present in this CSS class instantly then it could be that the browser is attempting + * to perform an unnecessary transition. + * + * This workaround, however, does not apply to standard class-based transitions that are rendered + * when a CSS class containing a transition is applied to an element: + * + * ```css + * .fade { + * /* this works as expected */ + * transition:1s linear all; + * opacity:0; + * } + * ``` + * + * Please keep this in mind when coding the CSS markup that will be used within class-based transitions. + * Also, try not to mix the two class-based animation flavors together since the CSS code may become + * overly complex. + * + * ### CSS Staggering Animations + * A Staggering animation is a collection of animations that are issued with a slight delay in between each successive operation resulting in a + * curtain-like effect. The ngAnimate module, as of 1.2.0, supports staggering animations and the stagger effect can be + * performed by creating a **ng-EVENT-stagger** CSS class and attaching that class to the base CSS class used for + * the animation. The style property expected within the stagger class can either be a **transition-delay** or an + * **animation-delay** property (or both if your animation contains both transitions and keyframe animations). + * + * ```css + * .my-animation.ng-enter { + * /* standard transition code */ + * -webkit-transition: 1s linear all; + * transition: 1s linear all; + * opacity:0; + * } + * .my-animation.ng-enter-stagger { + * /* this will have a 100ms delay between each successive leave animation */ + * -webkit-transition-delay: 0.1s; + * transition-delay: 0.1s; + * + * /* in case the stagger doesn't work then these two values + * must be set to 0 to avoid an accidental CSS inheritance */ + * -webkit-transition-duration: 0s; + * transition-duration: 0s; + * } + * .my-animation.ng-enter.ng-enter-active { + * /* standard transition styles */ + * opacity:1; + * } + * ``` + * + * Staggering animations work by default in ngRepeat (so long as the CSS class is defined). Outside of ngRepeat, to use staggering animations + * on your own, they can be triggered by firing multiple calls to the same event on $animate. However, the restrictions surrounding this + * are that each of the elements must have the same CSS className value as well as the same parent element. A stagger operation + * will also be reset if more than 10ms has passed after the last animation has been fired. + * + * The following code will issue the **ng-leave-stagger** event on the element provided: + * + * ```js + * var kids = parent.children(); + * + * $animate.leave(kids[0]); //stagger index=0 + * $animate.leave(kids[1]); //stagger index=1 + * $animate.leave(kids[2]); //stagger index=2 + * $animate.leave(kids[3]); //stagger index=3 + * $animate.leave(kids[4]); //stagger index=4 + * + * $timeout(function() { + * //stagger has reset itself + * $animate.leave(kids[5]); //stagger index=0 + * $animate.leave(kids[6]); //stagger index=1 + * }, 100, false); + * ``` + * + * Stagger animations are currently only supported within CSS-defined animations. + * + * ## JavaScript-defined Animations + * In the event that you do not want to use CSS3 transitions or CSS3 animations or if you wish to offer animations on browsers that do not + * yet support CSS transitions/animations, then you can make use of JavaScript animations defined inside of your AngularJS module. + * + * ```js + * //!annotate="YourApp" Your AngularJS Module|Replace this or ngModule with the module that you used to define your application. + * var ngModule = angular.module('YourApp', ['ngAnimate']); + * ngModule.animation('.my-crazy-animation', function() { + * return { + * enter: function(element, done) { + * //run the animation here and call done when the animation is complete + * return function(cancelled) { + * //this (optional) function will be called when the animation + * //completes or when the animation is cancelled (the cancelled + * //flag will be set to true if cancelled). + * }; + * }, + * leave: function(element, done) { }, + * move: function(element, done) { }, + * + * //animation that can be triggered before the class is added + * beforeAddClass: function(element, className, done) { }, + * + * //animation that can be triggered after the class is added + * addClass: function(element, className, done) { }, + * + * //animation that can be triggered before the class is removed + * beforeRemoveClass: function(element, className, done) { }, + * + * //animation that can be triggered after the class is removed + * removeClass: function(element, className, done) { } + * }; + * }); + * ``` + * + * JavaScript-defined animations are created with a CSS-like class selector and a collection of events which are set to run + * a javascript callback function. When an animation is triggered, $animate will look for a matching animation which fits + * the element's CSS class attribute value and then run the matching animation event function (if found). + * In other words, if the CSS classes present on the animated element match any of the JavaScript animations then the callback function will + * be executed. It should be also noted that only simple, single class selectors are allowed (compound class selectors are not supported). + * + * Within a JavaScript animation, an object containing various event callback animation functions is expected to be returned. + * As explained above, these callbacks are triggered based on the animation event. Therefore if an enter animation is run, + * and the JavaScript animation is found, then the enter callback will handle that animation (in addition to the CSS keyframe animation + * or transition code that is defined via a stylesheet). + * + */ + +angular.module('ngAnimate', ['ng']) + + /** + * @ngdoc provider + * @name $animateProvider + * @description + * + * The `$animateProvider` allows developers to register JavaScript animation event handlers directly inside of a module. + * When an animation is triggered, the $animate service will query the $animate service to find any animations that match + * the provided name value. + * + * Requires the {@link ngAnimate `ngAnimate`} module to be installed. + * + * Please visit the {@link ngAnimate `ngAnimate`} module overview page learn more about how to use animations in your application. + * + */ + .directive('ngAnimateChildren', function() { + var NG_ANIMATE_CHILDREN = '$$ngAnimateChildren'; + return function(scope, element, attrs) { + var val = attrs.ngAnimateChildren; + if (angular.isString(val) && val.length === 0) { //empty attribute + element.data(NG_ANIMATE_CHILDREN, true); + } else { + scope.$watch(val, function(value) { + element.data(NG_ANIMATE_CHILDREN, !!value); + }); + } + }; + }) + + //this private service is only used within CSS-enabled animations + //IE8 + IE9 do not support rAF natively, but that is fine since they + //also don't support transitions and keyframes which means that the code + //below will never be used by the two browsers. + .factory('$$animateReflow', ['$$rAF', '$document', function($$rAF, $document) { + var bod = $document[0].body; + return function(fn) { + //the returned function acts as the cancellation function + return $$rAF(function() { + //the line below will force the browser to perform a repaint + //so that all the animated elements within the animation frame + //will be properly updated and drawn on screen.
