| 13 | * @description |
| 14 | * |
| 15 | * The `ngAnimate` module provides support for JavaScript, CSS3 transition and CSS3 keyframe animation hooks within existing core and custom directives. |
| 16 | * |
| 17 | * <div doc-module-components="ngAnimate"></div> |
| 18 | * |
| 19 | * # Usage |
| 20 | * |
| 21 | * To see animations in action, all that is required is to define the appropriate CSS classes |
| 22 | * or to register a JavaScript animation via the myModule.animation() function. The directives that support animation automatically are: |
| 23 | * `ngRepeat`, `ngInclude`, `ngIf`, `ngSwitch`, `ngShow`, `ngHide`, `ngView` and `ngClass`. Custom directives can take advantage of animation |
| 24 | * by using the `$animate` service. |
| 25 | * |
| 26 | * Below is a more detailed breakdown of the supported animation events provided by pre-existing ng directives: |
| 27 | * |
| 28 | * | Directive | Supported Animations | |
| 29 | * |----------------------------------------------------------------------------------------------------------|--------------------------------------------------------------------------| |
| 30 | * | {@link ng.directive:ngRepeat#animations ngRepeat} | enter, leave and move | |
| 31 | * | {@link ngRoute.directive:ngView#animations ngView} | enter and leave | |
| 32 | * | {@link ng.directive:ngInclude#animations ngInclude} | enter and leave | |
| 33 | * | {@link ng.directive:ngSwitch#animations ngSwitch} | enter and leave | |
| 34 | * | {@link ng.directive:ngIf#animations ngIf} | enter and leave | |
| 35 | * | {@link ng.directive:ngClass#animations ngClass} | add and remove (the CSS class(es) present) | |
| 36 | * | {@link ng.directive:ngShow#animations ngShow} & {@link ng.directive:ngHide#animations ngHide} | add and remove (the ng-hide class value) | |
| 37 | * | {@link ng.directive:form#animation-hooks form} & {@link ng.directive:ngModel#animation-hooks ngModel} | add and remove (dirty, pristine, valid, invalid & all other validations) | |
| 38 | * | {@link module:ngMessages#animations ngMessages} | add and remove (ng-active & ng-inactive) | |
| 39 | * | {@link module:ngMessages#animations ngMessage} | enter and leave | |
| 40 | * |
| 41 | * You can find out more information about animations upon visiting each directive page. |
| 42 | * |
| 43 | * Below is an example of how to apply animations to a directive that supports animation hooks: |
| 44 | * |
| 45 | * ```html |
| 46 | * <style type="text/css"> |
| 47 | * .slide.ng-enter, .slide.ng-leave { |
| 48 | * -webkit-transition:0.5s linear all; |
| 49 | * transition:0.5s linear all; |
| 50 | * } |
| 51 | * |
| 52 | * .slide.ng-enter { } /* starting animations for enter */ |
| 53 | * .slide.ng-enter.ng-enter-active { } /* terminal animations for enter */ |
| 54 | * .slide.ng-leave { } /* starting animations for leave */ |
| 55 | * .slide.ng-leave.ng-leave-active { } /* terminal animations for leave */ |
| 56 | * </style> |
| 57 | * |
| 58 | * <!-- |
| 59 | * the animate service will automatically add .ng-enter and .ng-leave to the element |
| 60 | * to trigger the CSS transition/animations |
| 61 | * --> |
| 62 | * <ANY class="slide" ng-include="..."></ANY> |
| 63 | * ``` |
| 64 | * |
| 65 | * Keep in mind that, by default, if an animation is running, any child elements cannot be animated |
| 66 | * until the parent element's animation has completed. This blocking feature can be overridden by |
| 67 | * placing the `ng-animate-children` attribute on a parent container tag. |
| 68 | * |
| 69 | * ```html |
| 70 | * <div class="slide-animation" ng-if="on" ng-animate-children> |
| 71 | * <div class="fade-animation" ng-if="on"> |
| 72 | * <div class="explode-animation" ng-if="on"> |
| 73 | * ... |
| 74 | * </div> |
| 75 | * </div> |
| 76 | * </div> |
| 77 | * ``` |
| 78 | * |
| 79 | * When the `on` expression value changes and an animation is triggered then each of the elements within |
| 80 | * will all animate without the block being applied to child elements. |
| 81 | * |
| 82 | * ## Are animations run when the application starts? |
| 83 | * No they are not. When an application is bootstrapped Angular will disable animations from running to avoid |
| 84 | * a frenzy of animations from being triggered as soon as the browser has rendered the screen. For this to work, |
| 85 | * Angular will wait for two digest cycles until enabling animations. From there on, any animation-triggering |
| 86 | * layout changes in the application will trigger animations as normal. |
| 87 | * |
| 88 | * In addition, upon bootstrap, if the routing system or any directives or load remote data (via $http) then Angular |
| 89 | * will automatically extend the wait time to enable animations once **all** of the outbound HTTP requests |
| 90 | * are complete. |
| 91 | * |
| 92 | * ## CSS-defined Animations |
| 93 | * The animate service will automatically apply two CSS classes to the animated element and these two CSS classes |
| 94 | * are designed to contain the start and end CSS styling. Both CSS transitions and keyframe animations are supported |
| 95 | * and can be used to play along with this naming structure. |
| 96 | * |
| 97 | * The following code below demonstrates how to perform animations using **CSS transitions** with Angular: |
| 98 | * |
| 99 | * ```html |
| 100 | * <style type="text/css"> |
| 101 | * /* |
| 102 | * The animate class is apart of the element and the ng-enter class |
| 103 | * is attached to the element once the enter animation event is triggered |
| 104 | * */ |
| 105 | * .reveal-animation.ng-enter { |
| 106 | * -webkit-transition: 1s linear all; /* Safari/Chrome */ |
| 107 | * transition: 1s linear all; /* All other modern browsers and IE10+ */ |
| 108 | * |
| 109 | * /* The animation preparation code */ |
| 110 | * opacity: 0; |
| 111 | * } |
| 112 | * |
| 113 | * /* |
| 114 | * Keep in mind that you want to combine both CSS |
| 115 | * classes together to avoid any CSS-specificity |
| 116 | * conflicts |
| 117 | * */ |
| 118 | * .reveal-animation.ng-enter.ng-enter-active { |
| 119 | * /* The animation code itself */ |
| 120 | * opacity: 1; |
| 121 | * } |
| 122 | * </style> |
| 123 | * |
| 124 | * <div class="view-container"> |
| 125 | * <div ng-view class="reveal-animation"></div> |
| 126 | * </div> |
| 127 | * ``` |
| 128 | * |
| 129 | * The following code below demonstrates how to perform animations using **CSS animations** with Angular: |
| 130 | * |
| 131 | * ```html |
| 132 | * <style type="text/css"> |
| 133 | * .reveal-animation.ng-enter { |
| 134 | * -webkit-animation: enter_sequence 1s linear; /* Safari/Chrome */ |
| 135 | * animation: enter_sequence 1s linear; /* IE10+ and Future Browsers */ |
| 136 | * } |
| 137 | * @-webkit-keyframes enter_sequence { |
| 138 | * from { opacity:0; } |
| 139 | * to { opacity:1; } |
| 140 | * } |
| 141 | * @keyframes enter_sequence { |
| 142 | * from { opacity:0; } |
| 143 | * to { opacity:1; } |
| 144 | * } |
| 145 | * </style> |
| 146 | * |
| 147 | * <div class="view-container"> |
| 148 | * <div ng-view class="reveal-animation"></div> |
| 149 | * </div> |
| 150 | * ``` |
| 151 | * |
| 152 | * Both CSS3 animations and transitions can be used together and the animate service will figure out the correct duration and delay timing. |
| 153 | * |
| 154 | * Upon DOM mutation, the event class is added first (something like `ng-enter`), then the browser prepares itself to add |
| 155 | * the active class (in this case `ng-enter-active`) which then triggers the animation. The animation module will automatically |
| 156 | * detect the CSS code to determine when the animation ends. Once the animation is over then both CSS classes will be |
| 157 | * removed from the DOM. If a browser does not support CSS transitions or CSS animations then the animation will start and end |
| 158 | * immediately resulting in a DOM element that is at its final state. This final state is when the DOM element |
| 159 | * has no CSS transition/animation classes applied to it. |
| 160 | * |
| 161 | * ### Structural transition animations |
| 162 | * |
| 163 | * Structural transitions (such as enter, leave and move) will always apply a `0s none` transition |
| 164 | * value to force the browser into rendering the styles defined in the setup (.ng-enter, .ng-leave |
| 165 | * or .ng-move) class. This means that any active transition animations operating on the element |
| 166 | * will be cut off to make way for the enter, leave or move animation. |
| 167 | * |
| 168 | * ### Class-based transition animations |
| 169 | * |
| 170 | * Class-based transitions refer to transition animations that are triggered when a CSS class is |
| 171 | * added to or removed from the element (via `$animate.addClass`, `$animate.removeClass`, |
| 172 | * `$animate.setClass`, or by directives such as `ngClass`, `ngModel` and `form`). |
| 173 | * They are different when compared to structural animations since they **do not cancel existing |
| 174 | * animations** nor do they **block successive transitions** from rendering on the same element. |
| 175 | * This distinction allows for **multiple class-based transitions** to be performed on the same element. |
| 176 | * |
| 177 | * In addition to ngAnimate supporting the default (natural) functionality of class-based transition |
| 178 | * animations, ngAnimate also decorates the element with starting and ending CSS classes to aid the |
| 179 | * developer in further styling the element throughout the transition animation. Earlier versions |
| 180 | * of ngAnimate may have caused natural CSS transitions to break and not render properly due to |
| 181 | * $animate temporarily blocking transitions using `0s none` in order to allow the setup CSS class |
| 182 | * (the `-add` or `-remove` class) to be applied without triggering an animation. However, as of |
| 183 | * **version 1.3**, this workaround has been removed with ngAnimate and all non-ngAnimate CSS |
| 184 | * class transitions are compatible with ngAnimate. |
| 185 | * |
| 186 | * There is, however, one special case when dealing with class-based transitions in ngAnimate. |
| 187 | * When rendering class-based transitions that make use of the setup and active CSS classes |
| 188 | * (e.g. `.fade-add` and `.fade-add-active` for when `.fade` is added) be sure to define |
| 189 | * the transition value **on the active CSS class** and not the setup class. |
| 190 | * |
| 191 | * ```css |
| 192 | * .fade-add { |
| 193 | * /* remember to place a 0s transition here |
| 194 | * to ensure that the styles are applied instantly |
| 195 | * even if the element already has a transition style */ |
| 196 | * transition:0s linear all; |
| 197 | * |
| 198 | * /* starting CSS styles */ |
| 199 | * opacity:1; |
| 200 | * } |
| 201 | * .fade-add.fade-add-active { |
| 202 | * /* this will be the length of the animation */ |
| 203 | * transition:1s linear all; |
| 204 | * opacity:0; |
| 205 | * } |
| 206 | * ``` |
| 207 | * |
| 208 | * The setup CSS class (in this case `.fade-add`) also has a transition style property, however, it |
| 209 | * has a duration of zero. This may not be required, however, incase the browser is unable to render |
| 210 | * the styling present in this CSS class instantly then it could be that the browser is attempting |
| 211 | * to perform an unnecessary transition. |
| 212 | * |
| 213 | * This workaround, however, does not apply to standard class-based transitions that are rendered |
| 214 | * when a CSS class containing a transition is applied to an element: |
| 215 | * |
| 216 | * ```css |
| 217 | * /* this works as expected */ |
| 218 | * .fade { |
| 219 | * transition:1s linear all; |
| 220 | * opacity:0; |
| 221 | * } |
| 222 | * ``` |
| 223 | * |
| 224 | * Please keep this in mind when coding the CSS markup that will be used within class-based transitions. |
| 225 | * Also, try not to mix the two class-based animation flavors together since the CSS code may become |
| 226 | * overly complex. |
| 227 | * |
| 228 | * |
| 229 | * ### Preventing Collisions With Third Party Libraries |
| 230 | * |
| 231 | * Some third-party frameworks place animation duration defaults across many element or className |
| 232 | * selectors in order to make their code small and reuseable. This can lead to issues with ngAnimate, which |
| 233 | * is expecting actual animations on these elements and has to wait for their completion. |
| 234 | * |
| 235 | * You can prevent this unwanted behavior by using a prefix on all your animation classes: |
| 236 | * |
| 237 | * ```css |
| 238 | * /* prefixed with animate- */ |
| 239 | * .animate-fade-add.animate-fade-add-active { |
| 240 | * transition:1s linear all; |
| 241 | * opacity:0; |
| 242 | * } |
| 243 | * ``` |
| 244 | * |
| 245 | * You then configure `$animate` to enforce this prefix: |
| 246 | * |
| 247 | * ```js |
| 248 | * $animateProvider.classNameFilter(/animate-/); |
| 249 | * ``` |
| 250 | * </div> |
| 251 | * |
| 252 | * ### CSS Staggering Animations |
| 253 | * A Staggering animation is a collection of animations that are issued with a slight delay in between each successive operation resulting in a |
| 254 | * curtain-like effect. The ngAnimate module (versions >=1.2) supports staggering animations and the stagger effect can be |
| 255 | * performed by creating a **ng-EVENT-stagger** CSS class and attaching that class to the base CSS class used for |
| 256 | * the animation. The style property expected within the stagger class can either be a **transition-delay** or an |
| 257 | * **animation-delay** property (or both if your animation contains both transitions and keyframe animations). |
| 258 | * |
| 259 | * ```css |
| 260 | * .my-animation.ng-enter { |
| 261 | * /* standard transition code */ |
| 262 | * -webkit-transition: 1s linear all; |
| 263 | * transition: 1s linear all; |
| 264 | * opacity:0; |
| 265 | * } |
| 266 | * .my-animation.ng-enter-stagger { |
| 267 | * /* this will have a 100ms delay between each successive leave animation */ |
| 268 | * -webkit-transition-delay: 0.1s; |
| 269 | * transition-delay: 0.1s; |
| 270 | * |
| 271 | * /* in case the stagger doesn't work then these two values |
| 272 | * must be set to 0 to avoid an accidental CSS inheritance */ |
| 273 | * -webkit-transition-duration: 0s; |
| 274 | * transition-duration: 0s; |
| 275 | * } |
| 276 | * .my-animation.ng-enter.ng-enter-active { |
| 277 | * /* standard transition styles */ |
| 278 | * opacity:1; |
| 279 | * } |
| 280 | * ``` |
| 281 | * |
| 282 | * Staggering animations work by default in ngRepeat (so long as the CSS class is defined). Outside of ngRepeat, to use staggering animations |
| 283 | * on your own, they can be triggered by firing multiple calls to the same event on $animate. However, the restrictions surrounding this |
| 284 | * are that each of the elements must have the same CSS className value as well as the same parent element. A stagger operation |
| 285 | * will also be reset if more than 10ms has passed after the last animation has been fired. |
| 286 | * |
| 287 | * The following code will issue the **ng-leave-stagger** event on the element provided: |
| 288 | * |
| 289 | * ```js |
| 290 | * var kids = parent.children(); |
| 291 | * |
| 292 | * $animate.leave(kids[0]); //stagger index=0 |
| 293 | * $animate.leave(kids[1]); //stagger index=1 |
| 294 | * $animate.leave(kids[2]); //stagger index=2 |
| 295 | * $animate.leave(kids[3]); //stagger index=3 |
| 296 | * $animate.leave(kids[4]); //stagger index=4 |
| 297 | * |
| 298 | * $timeout(function() { |
| 299 | * //stagger has reset itself |
| 300 | * $animate.leave(kids[5]); //stagger index=0 |
| 301 | * $animate.leave(kids[6]); //stagger index=1 |
| 302 | * }, 100, false); |
| 303 | * ``` |
| 304 | * |
| 305 | * Stagger animations are currently only supported within CSS-defined animations. |
| 306 | * |
| 307 | * ## JavaScript-defined Animations |
| 308 | * 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 |
| 309 | * yet support CSS transitions/animations, then you can make use of JavaScript animations defined inside of your AngularJS module. |
| 310 | * |
| 311 | * ```js |
| 312 | * //!annotate="YourApp" Your AngularJS Module|Replace this or ngModule with the module that you used to define your application. |
| 313 | * var ngModule = angular.module('YourApp', ['ngAnimate']); |
| 314 | * ngModule.animation('.my-crazy-animation', function() { |
| 315 | * return { |
| 316 | * enter: function(element, done) { |
| 317 | * //run the animation here and call done when the animation is complete |
| 318 | * return function(cancelled) { |
| 319 | * //this (optional) function will be called when the animation |
| 320 | * //completes or when the animation is cancelled (the cancelled |
| 321 | * //flag will be set to true if cancelled). |
| 322 | * }; |
| 323 | * }, |
| 324 | * leave: function(element, done) { }, |
| 325 | * move: function(element, done) { }, |
| 326 | * |
| 327 | * //animation that can be triggered before the class is added |
| 328 | * beforeAddClass: function(element, className, done) { }, |
| 329 | * |
| 330 | * //animation that can be triggered after the class is added |
| 331 | * addClass: function(element, className, done) { }, |
| 332 | * |
| 333 | * //animation that can be triggered before the class is removed |
| 334 | * beforeRemoveClass: function(element, className, done) { }, |
| 335 | * |
| 336 | * //animation that can be triggered after the class is removed |
| 337 | * removeClass: function(element, className, done) { } |
| 338 | * }; |
| 339 | * }); |
| 340 | * ``` |
| 341 | * |
| 342 | * JavaScript-defined animations are created with a CSS-like class selector and a collection of events which are set to run |
| 343 | * a javascript callback function. When an animation is triggered, $animate will look for a matching animation which fits |
| 344 | * the element's CSS class attribute value and then run the matching animation event function (if found). |
| 345 | * In other words, if the CSS classes present on the animated element match any of the JavaScript animations then the callback function will |
| 346 | * be executed. It should be also noted that only simple, single class selectors are allowed (compound class selectors are not supported). |
| 347 | * |
| 348 | * Within a JavaScript animation, an object containing various event callback animation functions is expected to be returned. |
| 349 | * As explained above, these callbacks are triggered based on the animation event. Therefore if an enter animation is run, |
| 350 | * and the JavaScript animation is found, then the enter callback will handle that animation (in addition to the CSS keyframe animation |
| 351 | * or transition code that is defined via a stylesheet). |
| 352 | * |
| 353 | * |
| 354 | * ### Applying Directive-specific Styles to an Animation |
| 355 | * In some cases a directive or service may want to provide `$animate` with extra details that the animation will |
| 356 | * include into its animation. Let's say for example we wanted to render an animation that animates an element |
| 357 | * towards the mouse coordinates as to where the user clicked last. By collecting the X/Y coordinates of the click |
| 358 | * (via the event parameter) we can set the `top` and `left` styles into an object and pass that into our function |
| 359 | * call to `$animate.addClass`. |
| 360 | * |
| 361 | * ```js |
| 362 | * canvas.on('click', function(e) { |
| 363 | * $animate.addClass(element, 'on', { |
| 364 | * to: { |
| 365 | * left : e.client.x + 'px', |
| 366 | * top : e.client.y + 'px' |
| 367 | * } |
| 368 | * }): |
| 369 | * }); |
| 370 | * ``` |
| 371 | * |
| 372 | * Now when the animation runs, and a transition or keyframe animation is picked up, then the animation itself will |
| 373 | * also include and transition the styling of the `left` and `top` properties into its running animation. If we want |
| 374 | * to provide some starting animation values then we can do so by placing the starting animations styles into an object |
| 375 | * called `from` in the same object as the `to` animations. |
| 376 | * |
| 377 | * ```js |
| 378 | * canvas.on('click', function(e) { |
| 379 | * $animate.addClass(element, 'on', { |
| 380 | * from: { |
| 381 | * position: 'absolute', |
| 382 | * left: '0px', |
| 383 | * top: '0px' |
| 384 | * }, |
| 385 | * to: { |
| 386 | * left : e.client.x + 'px', |
| 387 | * top : e.client.y + 'px' |
| 388 | * } |
| 389 | * }): |
| 390 | * }); |
| 391 | * ``` |
| 392 | * |
| 393 | * Once the animation is complete or cancelled then the union of both the before and after styles are applied to the |
| 394 | * element. If `ngAnimate` is not present then the styles will be applied immediately. |
| 395 | * |

| 796 | /** |
| 797 | * @ngdoc service |
| 798 | * @name $animate |
| 799 | * @kind object |
| 800 | * |
| 801 | * @description |
| 802 | * The `$animate` service provides animation detection support while performing DOM operations (enter, leave and move) as well as during addClass and removeClass operations. |
| 803 | * When any of these operations are run, the $animate service |
| 804 | * will examine any JavaScript-defined animations (which are defined by using the $animateProvider provider object) |
| 805 | * as well as any CSS-defined animations against the CSS classes present on the element once the DOM operation is run. |
| 806 | * |
| 807 | * The `$animate` service is used behind the scenes with pre-existing directives and animation with these directives |
| 808 | * will work out of the box without any extra configuration. |
| 809 | * |
| 810 | * Requires the {@link ngAnimate `ngAnimate`} module to be installed. |
| 811 | * |
| 812 | * Please visit the {@link ngAnimate `ngAnimate`} module overview page learn more about how to use animations in your application. |
| 813 | * ## Callback Promises |
| 814 | * With AngularJS 1.3, each of the animation methods, on the `$animate` service, return a promise when called. The |
| 815 | * promise itself is then resolved once the animation has completed itself, has been cancelled or has been |
| 816 | * skipped due to animations being disabled. (Note that even if the animation is cancelled it will still |
| 817 | * call the resolve function of the animation.) |
| 818 | * |
| 819 | * ```js |
| 820 | * $animate.enter(element, container).then(function() { |
| 821 | * //...this is called once the animation is complete... |
| 822 | * }); |
| 823 | * ``` |
| 824 | * |
| 825 | * Also note that, due to the nature of the callback promise, if any Angular-specific code (like changing the scope, |
| 826 | * location of the page, etc...) is executed within the callback promise then be sure to wrap the code using |
| 827 | * `$scope.$apply(...)`; |
| 828 | * |
| 829 | * ```js |
| 830 | * $animate.leave(element).then(function() { |
| 831 | * $scope.$apply(function() { |
| 832 | * $location.path('/new-page'); |
| 833 | * }); |
| 834 | * }); |
| 835 | * ``` |
| 836 | * |
| 837 | * An animation can also be cancelled by calling the `$animate.cancel(promise)` method with the provided |
| 838 | * promise that was returned when the animation was started. |
| 839 | * |
| 840 | * ```js |
| 841 | * var promise = $animate.addClass(element, 'super-long-animation').then(function() { |
| 842 | * //this will still be called even if cancelled |
| 843 | * }); |
| 844 | * |
| 845 | * element.on('click', function() { |
| 846 | * //tooo lazy to wait for the animation to end |
| 847 | * $animate.cancel(promise); |
| 848 | * }); |
| 849 | * ``` |
| 850 | * |
| 851 | * (Keep in mind that the promise cancellation is unique to `$animate` since promises in |
| 852 | * general cannot be cancelled.) |
| 853 | * |

| 861 | * @description |
| 862 | * Performs an inline animation on the element which applies the provided `to` and `from` CSS styles to the element. |
| 863 | * If any detected CSS transition, keyframe or JavaScript matches the provided `className` value then the animation |
| 864 | * will take on the provided styles. For example, if a transition animation is set for the given className then the |
| 865 | * provided `from` and `to` styles will be applied alongside the given transition. If a JavaScript animation is |
| 866 | * detected then the provided styles will be given in as function paramters. |

| 879 | * |
| 880 | * | Animation Step | What the element class attribute looks like | |
| 881 | * |-------------------------------------------------------------------------------------------------------------------|------------------------------------------------------------| |
| 882 | * | 1. $animate.animate(...) is called | class="my-animation" | |
| 883 | * | 2. $animate waits for the next digest to start the animation | class="my-animation ng-animate" | |
| 884 | * | 3. $animate runs the JavaScript-defined animations detected on the element | class="my-animation ng-animate" | |
| 885 | * | 4. the className class value is added to the element | class="my-animation ng-animate className" | |
| 886 | * | 5. $animate scans the element styles to get the CSS transition/animation duration and delay | class="my-animation ng-animate className" | |
| 887 | * | 6. $animate blocks all CSS transitions on the element to ensure the .className class styling is applied right away| class="my-animation ng-animate className" | |
| 888 | * | 7. $animate applies the provided collection of `from` CSS styles to the element | class="my-animation ng-animate className" | |
| 889 | * | 8. $animate waits for a single animation frame (this performs a reflow) | class="my-animation ng-animate className" | |
| 890 | * | 9. $animate removes the CSS transition block placed on the element | class="my-animation ng-animate className" | |
| 891 | * | 10. the className-active class is added (this triggers the CSS transition/animation) | class="my-animation ng-animate className className-active" | |
| 892 | * | 11. $animate applies the collection of `to` CSS styles to the element which are then handled by the transition | class="my-animation ng-animate className className-active" | |
| 893 | * | 12. $animate waits for the animation to complete (via events and timeout) | class="my-animation ng-animate className className-active" | |
| 894 | * | 13. The animation ends and all generated CSS classes are removed from the element | class="my-animation" | |
| 895 | * | 14. The returned promise is resolved. | class="my-animation" | |
| 896 | * |
| 897 | * @param {DOMElement} element the element that will be the focus of the enter animation |
| 898 | * @param {object} from a collection of CSS styles that will be applied to the element at the start of the animation |
| 899 | * @param {object} to a collection of CSS styles that the element will animate towards |
| 900 | * @param {string=} className an optional CSS class that will be added to the element for the duration of the animation (the default class is `ng-inline-animate`) |
| 901 | * @param {object=} options an optional collection of options that will be picked up by the CSS transition/animation |
