Last Updated: 26 November 2022

Renders an uncontrolled <textarea> element that uses a callback function to pass its value to the parent component.

  • Use the defaultValue passed down from the parent as the uncontrolled input field's initial value.
  • Use the onChange event to fire the onValueChange callback and send the new value to the parent.
const TextArea = ({ cols = 20, rows = 2, defaultValue, onValueChange, ...rest }) => { return ( <textarea cols={cols} rows={rows} defaultValue={defaultValue} onChange={({ target: { value } }) => onValueChange(value)} {...rest} /> ); };
ReactDOM.render( <TextArea placeholder="Insert some text here..." onValueChange={val => console.log(val)} />, document.getElementById('root') );
