zh-CN: 获得选项的文本
|

en-US: Get value of selected item

|
||
## zh-CN
|
||
|
||
默认情况下 `onChange` 里只能拿到 value，如果需要拿到选中的节点文本 label，可以使用 `labelInValue` 属性。
|
||
|
||
选中项的 label 会被包装到 value 中传递给 `onChange` 等函数，此时 value 是一个对象。
|
||
|
||
## en-US
|
||
|
||
As a default behavior, the onChange callback can only get the value of the selected item. The labelInValue prop can be used to get the label property of the selected item.
|
||
|
||
The label of the selected item will be packed as an object for passing to the onChange callback.
|
||
|
||
```jsx
|
||
import { Select } from 'antd';
|
||
|
||
const { Option } = Select;
|
||
|
||
function handleChange(value) {
|
||
console.log(value); // { key: "lucy", label: "Lucy (101)" }
|
||
}
|
||
|
||
ReactDOM.render(
|
||
<Select
|
||
labelInValue
|
||
defaultValue={{ key: 'lucy' }}
|
||
style={{ width: 120 }}
|
||
onChange={handleChange}
|
||
>
|
||
<Option value="jack">Jack (100)</Option>
|
||
<Option value="lucy">Lucy (101)</Option>
|
||
</Select>,
|
||
mountNode,
|
||
);
|
||
```
