业务需求

弹窗实现视频播放，并且切换不同选项卡播放不同视频

1、实现的效果图

3、全部代码(复制粘贴即可实现)

<template>
  <el-button style="margin-left: 60px" type="primary" @click="playVideo()"
          >演示视频</el-button
        >
   <el-dialog
      title="操作视频"
      :visible.sync="dialogPlay"
      width="60%"
      @close="closeDialog"
    >
      <el-tabs
        :tab-position="tabPosition"
        v-model="editableTabsValue"
        @tab-click="handleClick"
      >
        <el-tab-pane
          :label="item.label"
          :name="item.value"
          v-for="(item, index) in paneList"
          :key="index"
        >
          <video
            id="video"
            controls
            controlslist="nodownload"   //内部视频，取消下载功能
            :src="videoUrl"
            class="video"
            :ref="dialogVideo"
            width="100%"
            autoplay="0"
          ></video>
        </el-tab-pane>
      </el-tabs>
    </el-dialog>
