ControlledInput react Code Snippet in 2024

Last Updated: 20 April 2024

Renders a controlled <input> element that uses a callback function to inform its parent about value updates.

  • Use the value passed down from the parent as the controlled input field's value.
  • Use the onChange event to fire the onValueChange callback and send the new value to the parent.
  • The parent must update the input field's value prop in order for its value to change on user input.
const ControlledInput = ({ value, onValueChange, ...rest }) => { return ( <input value={value} onChange={({ target: { value } }) => onValueChange(value)} {...rest} /> ); };
const Form = () => { const [value, setValue] = React.useState(''); return ( <ControlledInput type="text" placeholder="Insert some text here..." value={value} onValueChange={setValue} /> ); }; ReactDOM.render(<Form />, document.getElementById('root'));
