Get name of button onPress in react native

Question

I have two buttons that both call the same onPress function. In the callback I want to be able to differentiate between which was pressed.

Answer 1

To improve performance, you can bind the event handler in the constructor to have it rendered only once

Facebook tip (at the bottom of the page)

We generally recommend binding in the constructor or using the property initializer syntax, to avoid this sort of performance problem.

class MKRadioButtonWrapper extends React.PureComponent {
  constructor(props) {
    super(props);
    this.buttonPressed = this.buttonPressed.bind(this);
  }

  buttonPressed(){
    this.props.onPress(this.props.title);
  }

  render() {
    return (
    
    );
  }
}

class App extends React.Component {
  constructor(props) {
    super(props);

    this._toggle = this._toggle.bind(this);
  }

  _toggle(title) {
    //do what you want with the title
  }

  render() {
    return (
      
        

        
      
    );
  }
}
