zh-CN: 完全控制的上传列表
|
|
en-US: Complete control over file list

## 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.
|
|
|
|
```jsx
|
|
import { Upload, Button } from 'antd';
|
|
import { UploadOutlined } from '@ant-design/icons';
|
|
|
|
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;
|
|
});
|
|
|
|
this.setState({ fileList });
|
|
};
|
|
|
|
render() {
|
|
const props = {
|
|
action: 'https://www.mocky.io/v2/5cc8019d300000980a055e76',
|
|
onChange: this.handleChange,
|
|
multiple: true,
|
|
};
|
|
return (
|
|
<Upload {...props} fileList={this.state.fileList}>
|
|
<Button icon={<UploadOutlined />}>Upload</Button>
|
|
</Upload>
|
|
);
|
|
}
|
|
}
|
|
|
|
ReactDOM.render(<MyUpload />, mountNode);
|
|
```
