需要完成的效果是：点击树状图然后打开相应的视频，可以指定窗口切换，并在此基础上实现视频播放、关闭视频、开启声音、关闭声音、分屏以及云台操作（包括左右移动、上下移动以及缩放）

使用的海康web插件：由海康官网下载的H5视频播放器开发包 V2.1.2，解压完毕后目录如下：

第一步：引入必要的文件

在public下面创建文件夹，文件名称可以自己起名字，我这里的是lib下面的js，然后把demo文件下的这些文件复制到所创建的文件夹下，最后在public/index.html引入所需要的文件

引入：

<script src="<%= BASE_URL %>lib/js/h5player.min.js" charset="utf-8"></script>

然后在views下面创建一个vue文件：

父组件：

randomLenNum这个自己新建一个js放进去就好了

/**
 * 生成随机len位数字
 */
export const randomLenNum = (len, date) => {
  let random = '';
  random = Math.ceil(Math.random() * 100000000000000).toString().substr(0, len ? len : 4);
  if (date) random = random + Date.now();
  return random;
};
