项目问题记录 elementui ,videojs

项目用到elementui ,videojs，为了hls格式的视频流在弹框关闭后停止刷新，使用了dispose()注销player
再次打开弹窗报错

The element or ID supplied is not valid. (videojs)

后发现因el-dialog懒加载，videojs找不到需要初始化的playerID，因为需要防止hls视频流一直刷新必须要删除dom

完整解决方案如下（无关代码有省略）:

dialog捕捉关闭事件，开启事件，开启后事件

  <el-dialog title="视频播放" :visible.sync="videoVisible"  customClass="customClass"     @close="closevideo" @open="open" @opened="openvideo"> 
     <div style="position:relative;" v-html="videohtml"> 
     </div> 
     </div>

相关methods:

 closevideo() {
      if (this.player) {
        this.player.dispose(); // 该方法会重置videojs的内部状态并移除dom
        this.videohtml = '';
      }
      this.videoVisible = false;
    },
    handlePlay() {  
      this.videoVisible = true; 
    },
    open(){
       this.videohtml = '<video id="currentPlayer" class="video-js vjs-big-play-centered  vjs-default-skin " style="width:700px;height:393.75px" muted></video>';
    },
    openvideo() { 
       setTimeout(() => {
         this.$nextTick(() => { 
          this.player = Videojs("currentPlayer", this.options);
         });
    },300)
  }
