Ref w elementach funkcjonalnych
function CustomTextInput(props) {
// textInput must be declared here so the ref can refer to it const textInput = useRef(null);
function handleClick() {
textInput.current.focus(); }
return (
<div>
<input
type="text"
ref={textInput} /> <input
type="button"
value="Focus the text input"
onClick={handleClick}
/>
</div>
);
}
