效果图
实现步骤
1. 安装海康web插件，去海康威视官网上下载，官方不支持Mac，只支持Windows
https://open.hikvision.com/
2. 在index.html引入js文件，安装包里面有
<script src="static/jquery-1.12.4.min.js"></script>
<script src="static/jsencrypt.min.js"></script>
<script src="static/jsWebControl-1.0.0.min.js"></script>3. 代码实现，可兼容谷歌、火狐、360、edge

开发中遇到的问题及解决方法
1. 创建实例失败时重新唤起插件
文档错误 oWebControl.JS_WakeUp("VideoWebPlugin://")
正确方法如下
WebControl.JS_WakeUp("VideoWebPlugin://"); // 程序未启动时执行
2. 产品要求弹框显示后直接进行预览，不需要再次点击
实现过程
先初始化 this.initPlugin()
再执行预览方法 this.previewVideo()
未能实现，因为初始化方法是异步的
解决方法，给初始化方法传递一个回调函数
this.initPlugin(() => {
this.previewVideo();
});
3. 多窗口实时预览实现，效果图如下
切换到2x2模式，监听父组件传递过来的监控点编号，调预览方法
watch: {
monitorDeviceNo: {
handler(newV, oldV) {
this.cameraIndexCode = newV;
if (newV && this.playMode === 0) {
this.previewVideo();
} else if (newV && this.playMode === 1) {
this.backVideo();
}
}
}
}关闭弹框的是，需要调用停止所有预览的API
