vue中使用海康视频插件（1.监控）

使用条件
一.、引入依赖文件
jsencrypt.min.js
jsWebControl-1.0.0.min.js
注：必须在与 vue 的 根 index.html 文件中引入， main.js 中引入无效；
依赖文件及官方demo：官网下载

2、 template

<div class="video-wrap mt-16">
  <wrap
    class="video-box"
    v-for="(item, index) in realTimeData.videoConfig"
    :key="item.id"
  >
    <div :id="`playWnd${index}`" class="playWnd"></div>
  </wrap>
</div>

3、methods

/* 获取视频code */
    async getVideoCode() {
      this.realTimeData.videoLoad = true;
      const params = {
        area: "",
        enterprise: this.realTimeData.Warehouse.enterpriseName,
        street: "",
      };
      await getCamera(params).then((res) => {
        const videoCode = res.data.list.map(({ cameraIndexCode }) => ({
          cameraIndexCode,
        }));
        this.realTimeData.videoConfig = videoCode.map((item) => {
          return {
            code: item.cameraIndexCode,
            id: Math.floor(Math.random() * 100),
          };
        });
        this.initPlugin(videoCode);
      });
    },
    /* 建立插件实例 */

                cbIntegrationCallBack: (msg) => {
                  //注：不能使用外部函数调用，无效
                  if (msg?.responseMsg?.msg?.result) {

                    } else if (result == 1025) {
