我不明白为什么回调被立即调用,没有任何延迟,我已经阅读了文档,它说它解析css以检索转换持续时间.
但它似乎不起作用,这是我的代码:
这是我的幻灯片指令:
'use strict' class SlideController constructor: ($log,$scope) -> console.log 'controller init.' class Slide constructor: ($log,$animate) -> link = (scope,element,attrs) => scope.$watch 'slide.animation',(newValue,oldValue)-> $animate.addClass element,'enter-right',()-> console.log 'Animation ended!' return { link controller: ['$log','$scope',SlideController] replace: true restrict: 'E' scope: slide: '=' templateUrl: '/views/directives/postSlide.html' transclude: true } angular.module('app').directive 'postSlide',['$log','$animate',Slide]
这是我的css:
.post-slide.enter-left,.post-slide.leave-left,.post-slide.enter-right,.post-slide.leave-right{ position:absolute; left:0px; top:0px; } /** Enter/leave right **/ .post-slide.enter-right { -webkit-animation:0.5s enter-right; animation:0.5s enter-right; z-index:100; background-color:darkgreen; } .post-slide.leave-right { -webkit-animation:0.5s leave-right; animation:0.5s leave-right; z-index:10; background-color:darkred; } @keyframes enter-right { from { left:100%; } to { left:0; } } @-webkit-keyframes enter-right { from { left:100%; } to { left:0; } } @keyframes leave-right { from { left:0; } to { left:-100%; } } @-webkit-keyframes leave-right { from { left:0; } to { left:-100%; } }
解决方法
@H_301_26@ 我认为你不以正确的方式使用回调,addClass返回promise,而不是输入param with function.你应该像这样,在纯粹的js中:
scope.$watch('slide.animation',function(newValue,oldValue) { return $animate.addClass(element,'enter-right').then(function() { return console.log('Animation ended!'); }); });
建议:将动画持续时间增加到10秒,打开控制台,查找动画元素,并查看动画期间如何应用类.
