WHEN TO USE REACT'S REF ATTRIBUTE?
But it is not always a good idea to use the ref attribute. The general rule of thumb is to avoid it. The official React documentation mentions three occasions where you can use it because you have no other choice.
Managing focus, text selection, or media playback.
Integrating with third-party DOM libraries.
Triggering imperative animations.use ref in component reactjs
class MyComponent extends React.Component {
constructor(props) {
super(props);
this.myRef = React.createRef(); }
render() {
return <div ref={this.myRef} />; }
}use ref in component reactjs
function CustomTextInput(props) {
// textInput doit être déclaré ici pour que la ref puisse s’y référer const textInput = useRef(null);
function handleClick() {
textInput.current.focus(); }
return (
<div>
<input
type="text"
ref={textInput} /> <input
type="button"
value="Donner le focus au champ texte"
onClick={handleClick}
/>
</div>
);
