BUG表现：

在swiper的swiper-item中有个view，给他绑定了bindtap事件。

结果点击该view的时候，既触发了tap事件又触发了swiper的animationfinish事件。

在开发者工具上表现是正常的。

预期表现：

点击view时只触发tap事件不触发animationfinish事件

* 提供一个最简复现 Demo

<swiper class="p-area" indicator-dots="true" autoplay="{{autoplay}}" duration="500" bindanimationfinish="areaChange">     <block wx:for="{{areas}}" wx:key="unique">         <swiper-item>             <view class="swiper-item">                 <view class="area-name">{{item.name}}</view>                 <view>                     <view class="area-p {{p.value==currentp?'area-p-active':''}}" wx:for="{{item.ps}}" wx:key="unique" wx:for-item="p"                     data-value="{{p.value}}" data-name="{{p.name}}" catchtap='selectp'>                         <image style="width:100%" mode="widthFix" src="{{domain}}/img/p/forms/{{p.value}}-1.png"></image>                         <view class="area-pokmeon-name">{{p.value}} {{p.name}}</view>                     </view>                 </view>             </view>         </swiper-item>     </block> </swiper>
