AngularJS对SRC改变动画形象 [英] AngularJS animate image on src change

问题描述

我有一个AnuglarJS的应用程序，在那里我加载/从web服务改变一些图片...

I have an AnuglarJS app, where I load/change some images from a webservice...

控制器

.controller('PlayerCtrl', function($scope, programService) {
    ....
    programService.refresh(function(data) {
        $scope.program = data;
    });
    ....

模板

<img src="{{program.image}}" />

在从WebService我的应用程序的更新，预计图像的变化，我只想做一个淡出/淡入时发生这种情况，那怎么办呢？

When my app updates from the webservice the images changes as expected, I just want to make an fadeout / fadein when this happens, how can that be done?

是否有可能总是淡出/中时，图像的src改变？

Is it possible to always make a fadeout/in when a image src changes?
