怎么在chakraUi中的button上使用forwardRef

Chakra UI 提供了 `Button` 组件,而如果你想在 Chakra UI 的按钮上使用 `forwardRef`,主要是为了更好地支持用户自定义样式或功能,并能接收外部提供的 `ref` 对象。`forwardRef` 是 React 内置的高阶组件 API,允许你将 `ref` 传递到组件的底层 DOM 元素。
以下是使用 `forwardRef` 重构 Chakra UI `Button` 的简单示例:
首先,在 Chakra UI 的 Button 组件上加上 `forwardRef`:
```jsx
import { forwardRef, Button } from '@chakra-ui/core';
const CustomButton = forwardRef<HTMLButtonElement, any>((props, ref) => {
// 你可以在这里访问传入的 ref, 比如控制焦点或修改样式等
const handleFocus = (e: FocusEvent<HTMLButtonElement>) => {
if (ref.current) {
ref.current.focus();
}
};
return (
<Button {...props} ref={ref as React.RefObject<HTMLButtonElement>} onFocus={handleFocus}>
{/* 内容 */}
</Button>
);
});
```
在这个例子中,`CustomButton` 接收了一个 `ref` 参数,将其作为第二个参数类型指定为 `HTMLButtonElement`。然后,你在组件内部直接使用这个 `ref` 对象来操作按钮的 DOM。
现在你可以像这样使用 `CustomButton`:
```jsx
<CustomButton onClick={() => console.log("Clicked")} />
```
