|
|
en-US: Generate from tree data

## zh-CN
|
|
|
|
使用 `treeData` 把 JSON 数据直接生成树结构。
|
|
|
|
## en-US
|
|
|
|
The tree structure can be populated using `treeData` property. This is a quick and easy way to provide the tree content.
|
|
|
|
```jsx
|
|
import { TreeSelect } from 'antd';
|
|
|
|
const treeData = [
|
|
{
|
|
title: 'Node1',
|
|
value: '0-0',
|
|
children: [
|
|
{
|
|
title: 'Child Node1',
|
|
value: '0-0-1',
|
|
},
|
|
{
|
|
title: 'Child Node2',
|
|
value: '0-0-2',
|
|
},
|
|
],
|
|
},
|
|
{
|
|
title: 'Node2',
|
|
value: '0-1',
|
|
},
|
|
];
|
|
|
|
class Demo extends React.Component {
|
|
state = {
|
|
value: undefined,
|
|
};
|
|
|
|
onChange = value => {
|
|
console.log(value);
|
|
this.setState({ value });
|
|
};
|
|
|
|
render() {
|
|
return (
|
|
<TreeSelect
|
|
style={{ width: '100%' }}
|
|
value={this.state.value}
|
|
dropdownStyle={{ maxHeight: 400, overflow: 'auto' }}
|
|
treeData={treeData}
|
|
placeholder="Please select"
|
|
treeDefaultExpandAll
|
|
onChange={this.onChange}
|
|
/>
|
|
);
|
|
}
|
|
}
|
|
|
|
ReactDOM.render(<Demo />, mountNode);
|
|
```
