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.
|
|
|
|
```tsx
|
|
import { Select } from 'antd';
|
|
import React from 'react';
|
|
|
|
const { Option } = Select;
|
|
|
|
const handleChange = (value: { value: string; label: React.ReactNode }) => {
|
|
console.log(value); // { value: "lucy", key: "lucy", label: "Lucy (101)" }
|
|
};
|
|
|
|
const App: React.FC = () => (
|
|
<Select
|
|
labelInValue
|
|
defaultValue={{ value: 'lucy', label: 'Lucy (101)' }}
|
|
style={{ width: 120 }}
|
|
onChange={handleChange}
|
|
>
|
|
<Option value="jack">Jack (100)</Option>
|
|
<Option value="lucy">Lucy (101)</Option>
|
|
</Select>
|
|
);
|
|
|
|
export default App;
|
|
```
