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:
-
limit the number of uploaded files.
-
read from response and show file link.
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);
