第一步：下载海康的js包，并在html中引入：
第二步：在相应的页面中开始编写，具体代码如下：
<template>
<el-container>
<el-aside width="300px">
<el-tree
node-key="id"
:data="treeData"
:props="defaultProps"
style="min-height: 580px"
@node-click="handleNodeClick"
/>
</el-aside>
<el-main>
<div ref="playWndBox">
<!-- 视频数据站位 -->
<div
id="playWnd"
class="playWnd"
:style="{
height: playWndHeight + 'px',
width: playWndWidth + 'px',
}"
/>
</div>
</el-main>
</el-container>
</template>
<script>
