Focus on div without click in React to enable keyboard navigation on a module
I am coding an image gallery from scratch in React, when clicking on an image, a modal pops up (separate component from my gallery component). I want to navigate between the pictures with left and right arrow, not just with the added arrows on the screen (onclick) but at the moment it only focuses on the modal when I click on it once, then I can navigate with the keyboard too (onKeyDown).
I have added tabIndex="0" to my div, but I still need to click on the div once to focus on it.
<div tabIndex="0" onKeyDown={(event) => this.onKeyNavigation(event, ImageUrl, currentIndex, ImageUrls)}>
onKeyNavigation = (event, ImageUrl, currentIndex, ImageUrls) => {
if ((event.keyCode) === 39) {
this.props.loadNext(ImageUrl, currentIndex, ImageUrls)
}
else if ((event.keyCode) === 37) {
this.props.loadPrevious(ImageUrl, currentIndex, ImageUrls)
}
else if ((event.keyCode) === 27) {
this.props.onClose()
}
}

You'll need to fire a focus() event on the <div> you want to have focus after it has rendered.
The easiest way to do this is to use React's built-in lifecycle methods. First, create a ref for the element you want to have focus (in this case, the div listening for keyDown events). Then, you can call focus() on that node in your component's componentDidMount() method:
class ImageGallery extends React.Component {
construtor(){
super();
// Create the ref in the constructor
this.focusRef = React.createRef();
}
/* your other methods here */
componentDidMount(){
// Focus on the rendered div using the DOM focus() method
this.focusRef.focus();
}
render(){
// Set the ref in your render() method
return(<div ref={this.focusRef} onKeyDown={this.handle}></div>);
}
}

You'll need to investigate to make sure the ref is getting set properly. Different versions of React handle this differently; you may need to set it as a function on the element (i.e.ref={div => this.focusRef = div}but the main idea still holds - you need to set focus on the element after render, and you can use the DOM node methodfocus()to do that.

I have React 16.6.1. I have gone through the documentation here: [link] reactjs.org/blog/2018/03/29/react-v-16-3.html I have also tried it withcomponentDidMount() { this.inputRef.current.focus(); }I cannot seem to figure it out how to set the ref properly.

So the solution was:
componentDidUpdate(){
this.focusRef.current.focus();
}
