微信小程序（16）-- bindtap,catchtap事件绑定的区别

bindtap,catchtap事件绑定的区别，这里就涉及冒泡事件了。bind事件绑定不会阻止冒泡事件向上冒泡，catch事件绑定可以阻止冒泡事件向上冒泡。

<view class="view1" bindtap="view1"> 
view1 
  <view class="view2" bindtap="view2">  
  view2
    <view class="view3" catchtap="view3">view3</view>  
  </view>  
</view>

    console.log("---view1 bindtap click")
  }, 
  view2: function () {
