Introduction#
useObjectRef
is a utility function that will give an object ref back regardless of if a
callback ref or object ref was passed in. This is useful for passing refs to React Aria hooks.
Example#
import {useButton, useObjectRef} from 'react-aria';
import {AriaButtonProps} from '@react-types/button';
let Button = React.forwardRef(
(props: AriaButtonProps, ref: React.ForwardedRef<HTMLButtonElement>) => {
let objRef = useObjectRef(ref);
let { buttonProps } = useButton(props, objRef);
let { children } = props;
return (
<button {...buttonProps} ref={objRef}>
{children}
</button>
);
}
);
function MyButton(props) {
let ref = React.useRef(null);
return (
<Button ref={ref} onPress={() => console.log(ref.current)}>
{props.children}
</Button>
);
}
