[AngularJS] AngularJS系列(5) 中级篇之动画
目录
ng动画实际帮我们在状态切换的时候 添加特定的样式 从而实现动画效果.
一般我们会通过C3来实现具体的动画.
CSS定义
ng-if
图(实际上,图并不能展现出什么):
HTML
<body ng-app="myApp"> <button ng-click="show=!show">Toggle</button> <div ng-if="show" class="fade">Look Me</div> <script type="text/javascript"> angular.module('myApp', ['ngAnimate']) </script> </body>
CSS
.fade { transition: 1s linear all; } .fade.ng-enter { opacity: 0; } .fade.ng-enter.ng-enter-active { opacity: 1; } .fade.ng-leave { opacity: 1; } .fade.ng-leave.ng-leave-active { opacity: 0; }
enter和leave的执行过程:
在元素创建的时候,会依次加上.ng-enter、.ng-enter-active的class,然后恢复为默认的class
同样在销毁的时候,会依次加上.ng-leave、.ng-leave-active的class,然后恢复为默认。
ngClass
这里只截取关键代码
<button ng-click="onOff=!onOff">Toggle</button> <div ng-class="{on:onOff}" class="highlight"> Highlight this box </div>
CSS
.highlight { transition: 1s linear all; } .highlight.on-add { background: red; } .highlight.on { background: yellow; } .highlight.on-remove { background: blue; }
效果图:
1.5.8支持的指令与动画样式:
Directive | Supported Animations |
---|---|
{@link ng.directive:ngRepeat#animations ngRepeat} | enter, leave and move |
{@link ngRoute.directive:ngView#animations ngView} | enter and leave |
{@link ng.directive:ngInclude#animations ngInclude} | enter and leave |
{@link ng.directive:ngSwitch#animations ngSwitch} | enter and leave |
{@link ng.directive:ngIf#animations ngIf} | enter and leave |
{@link ng.directive:ngClass#animations ngClass} | add and remove (the CSS class(es) present) |
{@link ng.directive:ngShow#animations ngShow} & {@link ng.directive:ngHide#animations ngHide} | add and remove (the ng-hide class value) |
{@link ng.directive:form#animation-hooks form} & {@link ng.directive:ngModel#animation-hooks ngModel} | add and remove (dirty, pristine, valid, invalid & all other validations) |
{@link module:ngMessages#animations ngMessages} | add and remove (ng-active & ng-inactive) |
{@link module:ngMessages#animations ngMessage} | enter and leave |
JS定义
HTML
<body ng-app="myApp" ng-init="items=[1,2,3,4,5,6]"> <button ng-click="show=!show">Toggle</button> <div ng-if="show" ng-repeat="item in items" class="slide"> {{ item }} </div> </body>
js操作
angular.module('myApp', ['ngAnimate']) .animation('.slide', [ function () { return { enter: function (element, doneFn) { jQuery(element).fadeIn(1000, doneFn); }, move: function (element, doneFn) { jQuery(element).fadeIn(1000, doneFn); }, leave: function (element, doneFn) { jQuery(element).fadeOut(1000, doneFn); } } } ]);
其中的enter move leave 对应状态变化的事件,详情建议参考源码中的$$AnimateJsProvider.
