## zh-CN

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。

## en-US

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.

````jsx
import { Upload, Button, Icon } from 'antd';

class MyUpload extends React.Component {
  state = {
    fileList: [{
      uid: '-1',
      name: 'xxx.png',
      status: 'done',
      url: 'http://www.baidu.com/xxx.png',
    }],
  }

  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 false;
    });

    this.setState({ fileList });
  }

  render() {
    const props = {
      action: '//jsonplaceholder.typicode.com/posts/',
      onChange: this.handleChange,
      multiple: true,
    };
    return (
      <Upload {...props} fileList={this.state.fileList}>
        <Button>
          <Icon type="upload" /> Upload
        </Button>
      </Upload>
    );
  }
}

ReactDOM.render(<MyUpload />, mountNode);
