Safari: focus event doesn't work on button element

Question

The focus event works fine on all browsers but Safari when it has been clicked.

And it works fine on div[tabindex] element, but don't work on button or input:button element.

It also can get the focus event when I use $('.btn').focus().

Why does the focus event haven't triggered on click ?

Here is my code:

 $(".btn").focus(function (e) { $(".result").append("<p>Event:"+e.type+", target:"+e.target+"</p>"); })

 .result{min-height:200px;border:1px solid #000;}

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script> <button class="btn">button 1</button> <input type="button" class="btn" value="button 2"/> <div class="btn" tabindex="0">div element</div> <h1> Result: </h1> <div class="result"> </div>

Why does the focus event haven't triggered on click ?

We found through research that Safari and FireFox on Macs do not set focus on buttons when you click on them.

The way we fixed that was to add a click listener to our buttons and call focus() on the button that was clicked.

In Angular it looked like this:

<button (click)="myClickFunction(); $event.target.focus();>My Button</button>

See https://bugs.webkit.org/show_bug.cgi?id=13724

This is working as intended on MacOS. Clicking a button, radio button, or checkbox doesn't give the element focus- thus it can't lose focus and trigger a blur.

The solution is to give it a click event that gives the element focus.

This might fix the issue: https://stackoverflow.com/a/1269767/2731261

$(".btn").mouseup(function(e){
    e.preventDefault();
});

Angular 8+ solution:

1. in your button tag add #toggleButton and (click)="onClick(); $event.stopPropagation()"

exp:

<button #toggleButton type="button"
    (click)="onClick(); $event.stopPropagation()"></button>

2. in your component.ts add ==>before constructor

*** @ViewChild('toggleButton', { static: true }) toggleButton: ElementRef;

---

onclick(){
        this.toggleButton.nativeElement.focus();
}
