创建容器

<template>
  <div class="right" ref="playWndBox">
    <!-- 视频数据站位 -->
    <div id="playWnd" class="playWnd" :style="{height: playWndHeight + 'px',width: playWndWidth + 'px'}"></div>
  </div>
</template>

插件所需参数

data() {
  return {
    // 视频盒子的高度
    playWndHeight: '',
    // 视频盒子的宽度
    playWndWidth: '',
    oWebControl:null,
    initCount:0,
    pubKey:'',
    playMode: 0, // 0 预览 1回放
    cameraIndexCode: '', // 监控点编号
    objData:{
      appkey: "25585539",
      ip: "39.129.177.31",
      port: 1443,
      secret: "D2E6l7ndVKGxow5X7ZYU"
    }
  }
},

初始化方法

mounted() {
  // 首次加载时的到父容器的高度
  this.playWndHeight = this.$refs.playWndBox.clientHeight
  // 首次加载时的到父容器的宽度
  this.playWndWidth = this.$refs.playWndBox.clientWidth
  // 初始化摄像头
  this.$nextTick(() => {
    this.initPlugin()
  })
  // 监听resize事件,使插件窗口尺寸跟随DIV窗口变化
  window.addEventListener('resize', () => {
    if (this.oWebControl != null) {
      this.oWebControl.JS_Resize(
        this.$refs.playWndBox.clientWidth,
        this.$refs.playWndBox.clientHeight
      )
    }
  })
},

只需要调用预览方法 previewVideo,更改 cameraIndexCode 值的就可以实现预览。还需注意 init 初始化时 appkey、ip、port、secret应改为自己的参数,不然视频无法预览

    let that = this;

    that.oWebControl = new WebControl({
