## zh-CN
|
||
|
||
通过 `Form.useForm` 对表单数据域进行交互。
|
||
|
||
> 注意 `useForm` 是 [React Hooks](https://reactjs.org/docs/hooks-intro.html) 的实现，只能用于函数组件，class 组件请查看下面的例子。
|
||
|
||
## en-US
|
||
|
||
Call form method with `Form.useForm`.
|
||
|
||
> Note that `useForm` is a [React Hooks](https://reactjs.org/docs/hooks-intro.html) that only works in functional component.
