1.效果

2.数据结构;根据name或url后缀来判断是图片或者视频类型

fileList = [
          {name:'123.mp4',url:'123.mp4'},
          {name:'124.png',url:'https://img0.baidu.com/it/u=1942253063,3807598283&fm=253&fmt=auto&app=138&f=JPEG?w=500&h=500'},
          {name:'hahagwe.png',url:'https://img0.baidu.com/it/u=1040225459,210273596&fm=253&fmt=auto&app=138&f=JPEG?w=400&h=400'},
        ]

3.判断是否是图片或者视频的方法

  //图片视频匹配
      matchType(name){
        //后缀获取
        let suffic = '';
        //获取类型结果
        let result = '';
        try {
          let fileArr = name.split('.');
          suffic = fileArr[fileArr.length - 1]
          // console.log('suffic',suffic);
        } catch (error) {
            suffic = ''
        }
        //图片格式
        var imgList = ['png','jpg','jpeg','bmp','gif'];
        //进行图片匹配
        result = imgList.some(item=>{
          return item === suffic
        })
        // console.log('结果',result);
        if(result){
          result = 'image';
          // console.log('结果',result);
          return result
        }
      },

4.全部代码展示—>子组件
