使用海康威视网络插件的 Vue - 监控实时回放

一、在index.html文件中引入以下3个js文件

    <!-- 引入海康插件内容 -->
    <script type="text/javascript" src="./haikang/jquery-1.12.4.min.js"></script>
    <script type="text/javascript" src="./haikang/jsencrypt.min.js"></script>
    <script type="text/javascript" src="./haikang/jsWebControl-1.0.0.min.js"></script>

这3个js文件在官网案例Web插件中有他也提供了案例来进行测试:https://open.hikvision.com/download/5c67f1e2f05948198c909700?type=10

二、上代码，将以下代码封装成组件在 components下新建/video/monitorVideo.vue（随意命名）

<template>
  <div
    id="hikvision-grid"
    class="wrapper"
    ref="wrapper"
    style="width: 100%; height: 100%; clear: both"
  >
    <div
      v-show="oWebControl"
      :id="setting.id"
      :class="[oWebControl === null ? 'videoNull' : '']"
    ></div>

    <br />
    <div v-show="!oWebControl">
      <div v-html="playText"></div>
      <br />
      <div v-show="playText.includes('插件启动失败')">
        下载完成？
        <el-button type="primary" @click="destroyedAndCreate">
          点击此处
        </el-button>
        启动插件
      </div>
    </div>
  </div>
</template>

将这里补充完整即可

三、在项目的地方引入组件使用

<div style="width: 1000px; height: 500px">
          <monitorVideoVue :list="curShowList"></monitorVideoVue>
 </div>

<script>
    import monitorVideoVue from "../components/video/monitorVideo.vue";
    components: {
      monitorVideoVue
     },
    data(){
      videoListAll: [],
      curShowList: [], // 当前能显示的摄像头                
    },
    methods: {
      getxxxxxxVideo().then((res) => {
        this.videoListAll = res.data;
      })
      for (let i = 0; i <= 3; i++) { //这里我只拿了4个索引码传过去，要多少看你们自己
        this.curShowList.push(videoListAll[i].cameraIndexCode)
      }
    }
</script>

如代码有错误请纠正
