ReactJS and autofocus

I have a react-bootstrap modal with an <input>. I want to set the autofocus attribute on the <input>

The following works fine, but shows a warning in the console

<input type="text" autofocus='true' />

Warning: Invalid DOM property `autofocus`. Did you mean `autoFocus`?

The following options do not work, in the sense that they do not focus the input when opening the modal:

<input type="text" autoFocus='true' />
<input type="text" autoFocus={true} />
<input type="text" autoFocus />

What is the recommended way of setting autofocus. Or how should I mute the warnings for the example that works well?

Note: This is react 16.8.6

Solution

  • Refs is what you want,

    constructor(props) {
    super(props);
    this.myRef = React.createRef();
}

componentDidMount(){
  this.myRef.current.focus();
}

<input type="text"  ref={this.myRef} />
