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.
