#### 完全控制的上传列表 使用 `fileList` 对列表进行完全控制，可以实现各种自定义功能，以下演示三种情况： 1) 上传列表数量的限制。 2) 读取远程路径并显示链接。 3) 按照服务器返回信息筛选成功上传的文件。 #### Complete control over file list You can gain full control over filelist by configuring `fileList`. You can accomplish all kinds of customed functions. The following shows three circumstances: 1) limit the number of uploaded files. 2) read from response and show file link. 3) filter successfully uploaded files according to response from server.

export default {

        status: 'done',
        url: 'http://www.baidu.com/xxx.png',
      }],
    }
  },
  methods: {
    handleChange(info) {
      let fileList = info.fileList;

      // 1. Limit the number of uploaded files
      //    Only to show two recent uploaded files, and old ones will be replaced by the new
      fileList = fileList.slice(-2);

      // 2. read from response and show file link
      fileList = fileList.map((file) => {
        if (file.response) {
          // Component will show file.url as link
          file.url = file.response.url;
        }
        return file;
      });

      // 3. filter successfully uploaded files according to response from server
      fileList = fileList.filter((file) => {
        if (file.response) {
          return file.response.status === 'success';
        }
        return true;
      });

      this.fileList = fileList
    },
  },
