问题
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
回答1:
Refs is what you want,
constructor(props) {
super(props);
this.myRef = React.createRef();
}
componentDidMount(){
this.myRef.current.focus();
}
<input type="text" ref={this.myRef} />
