angular.js - angular双向数据绑定问题？

Question

console.log()打印playPauseIcon的值为 Object {pause: 1}
<button class="iconButton play" ng-click="onClickPlayPause()" ng-class="playPauseIcon" aria-label="Play/Pause"></button>
问题就在这 class里面的play应该为pause才对。多次点击就会出现这种情况。时好时坏的那种感觉，
双向绑定怎么会出现这种问题啊，很郁闷啊。

Answer 1

The fields starting with

aria are for assistive programs for people with disabilities. I didn’t see your onClick code or where the button text is assigned..
