微信小程序实现图片翻转效果的实例代码

<view class='rotateCtn' bindtap='rotateFn'>
 <!--正面的框 -->
 <view class='frame {{class1}}'>
  <image src="{{vo.cover1}}"></image>
 </view>
 <!--背面的框 -->
 <view class='frame {{class2}}'>
  <image src="{{vo.cover2}}"></image>
 </view>
</view>

  class1: 'z1', //默认正面在上面
  class2: 'z2'
 },

  let data = this.data;

   this.run('front', 'back', 'z2', 'z1');
