开发需求又来了 要模仿抖音做视频播放还要上下滑动。 找了下资料Swiper可以。

先上效果图

原理主要是通过position:absolute 控制层级z-index来控制视频的播放，全局的video标签只有一个。
上代码：

<template>
  <div class="wrap">
    <div class="my-video works_wraps" v-show="show" :style="VideoItemHeightStyle">
      <video class="video" :src="showVideo.Video.videoPath"
             :poster="showVideo.Video.videoCover"
             webkit-playsinline="true"
             controlslist="nodownload"
             playsinline="true"
             x5-video-player-type="h5"
             x5-video-player-fullscreen="true"
             preload="metadata"
             loop="loop"
             @loadeddata="watchHandler"
             ref="video"
      >
        <!--@pause="onpause"-->
        <!--@play="onplay"-->
        <source :src="showVideo.Video.videoPath" type="video/mp4">
      </video>
    </div>

    <swiper :options="swiperOption" v-if="popularVideo.length > 0">
      <swiper-slide v-for="(item, index) in popularVideo">
