微信小程序实现抖音播放效果的实例代码

<swiper class="swiper" vertical='true' easing-function='default' bindchange='bindchange'>
	<block wx:for="{{weishipinglist}}" wx:for-item="key" wx:key="*this">
		<swiper-item>
			<view class="video-wrap">
				<video wx:if="{{index==hkindex}}" class="video" autoplay="{{true}}" lopp='{{true}}' src="/UploadFiles/2021-04-02/{{key.videoid}}">



data: {
  weishipinglist: [],//视频数据
  hkindex: 0,//滑块index
 },
 //动态更新当前滑块下标
 bindchange(e) {
  this.setData({
   hkindex: e.detail.current
  })
  if (e.detail.current%10 == 7) {
   this.chaxunzhi(); //此处是表示在快要加载完了需在分页请求加载
  }
 },




//css代码可能有多余的 我就不挑了 引入时自己按需引入吧

完了需要注意的就是一个分页加载 我设置的是7因为我们数据是一页10条 会在第7条加载第二页数据

wx:if="{{index==hkindex}}" 这个起到的是控制加载要不会多个同时播放没刷到的也会播放 现在只会播放当前页面视频

总结
