微信小程序swiper组件实现抖音翻页切换视频功能

<!-- 自定义头部导航栏 -->
<cover-view style="height:{{statusBarHeight+navBarHeight}}px">
 <navigator open-type="navigateBack">
  <cover-image src="../../icon/返回.png" /> <!--填写自己的图标地址-->
 </navigator>
</cover-view>
 
<!--swiper实现整屏划动播放视频-->
<swiper vertical duration="200" bindchange="slide" style="height:{{screenHeight}}px; width:100%;background:#000">
 <block wx:for="{{video}}" wx:key="id">
  <swiper-item style="height:100%; width:100%">
   <video wx:if="{{index==changeIndex}}" style="height:100%; width:100%" src="{{item.video}}" aulay="true" />
  </swiper-item>
 </block>
</swiper>
 
<!-- swiper中background:#000; 设置swiper背景色 否则翻页的时候会有白影 影响效果 -->
