## 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,以下演示二种情况:
1. 上传列表数量的限制。
2. 读取远程路径并显示链接。
## en-US
You can gain full control over filelist by configuring `fileList`. You can accomplish all kinds of customed functions. The following shows two circumstances:
1. limit the number of uploaded files.
2. read from response and show file link.
```tsx
import { UploadOutlined } from '@ant-design/icons';
import type { UploadProps } from 'antd';
import { Button, Upload } from 'antd';
import type { UploadFile } from 'antd/es/upload/interface';
import React, { useState } from 'react';
const App: React.FC = () => {
const [fileList, setFileList] = useState<UploadFile[]>([
{
uid: '-1',
name: 'xxx.png',
status: 'done',
url: 'http://www.baidu.com/xxx.png',
},
]);
const handleChange: UploadProps['onChange'] = info => {
let newFileList = [...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
newFileList = newFileList.slice(-2);
// 2. Read from response and show file link
newFileList = newFileList.map(file => {
if (file.response) {
// Component will show file.url as link
file.url = file.response.url;
}
return file;
});
setFileList(newFileList);
};
const props = {
action: 'https://www.mocky.io/v2/5cc8019d300000980a055e76',
onChange: handleChange,
multiple: true,
};
return (
<Upload {...props} fileList={fileList}>
<Button icon={<UploadOutlined />}>Upload</Button>
</Upload>
);
};
export default App;
```
