预览功能实现

需求：将后端返回来的文字或者图片和视频展示在页面上。

        <!-- 预览 -->
        <el-dialog title="预览" :visible.sync="dialogPreviewVisible" width="50%" append-to-body :close-on-click-modal="false" @close="PreviewClose">
          <div style="margin-bottom:5%">
            <h1>{{previewTitle}}</h1>
          </div>
          <div class="content" v-html="previewContent">
          </div>
        </el-dialog>
      
// 预览事件
      previewButton(row){
        let _this = this;
        let isNull = validatenull;
        getDetails(row.id).then((res)=>{
          if(res.data.code == 0){
            _this.dialogPreviewVisible = true;
            console.log(res.data.data,'预览');
            _this.previewTitle = res.data.data.title
            _this.previewContent = res.data.data.content
            console.log(res.data.data.content,'66666');
          }
        })
      },


  <style scoped lang="scss">
  .titleClass{
    display:flex;
    justify-content: center;
  }
  .content{
   /deep/ p{
           img{
             width: 100% !important;
           }
         }
    /deep/ .ql-video{
        position: static;
        }
      }
  </style>
