How to autofocus react textarea?

Question

I already try autoFocus or focus(), but seems not work.

<textarea autoFocus />

or

<textarea ref="textarea" />
componentDidMount() {
  findDOMNode(this.refs.textarea).focus();
}

edit

autoFocus seems work in chrome.

Both autoFocus foucs() not work in iOS.

Answer 1

Calling focus() in componentDidMount seems to work in desktop Chrome and Firefox.

Demo.

It seems that Mobile Safari intentionally suppresses auto-focussing of elements.
