Web Tools #382 - Frameworks, JSON & SQL, Vue Tools

There's an obscure tidbit in MDN's article on the focus() method that I just stumbled across. As you might know, any HTML element that's focusable (e.g. an input or any element with a tabindex value) can receive focus programmatically via JavaScript.

You simply get a reference to the element and use element.focus() to make it behave as if it was tabbed into or selected with the mouse.

But notice what MDN says:

"If you call HTMLElement.focus() from a mousedown event handler, you must call event.preventDefault() to keep the focus from leaving the HTMLElement."

It's probably rare that you would have to do this, but I'm always a sucker for these obscure little factoids when it comes to DOM/JavaScript. So I've set up a quick-and-dirty CodePen demo where you can try this out.

The first two buttons use click and mouseup, and they work fine. But the third button uses mousedown and although the code is the same, the focus doesn't take effect on the targeted input element. When preventDefault() is added, then the focus is successful:

I don't know for certain why this is needed, but my best guess is that when you do a 'mouse down' action, the 'default' action that naturally follows a 'mouse down' is that the element being 'moused down' then receives focus due to the 'mouse up' action that follows.

But if that were true, that would mean holding the mouse down without mousing up should work too. But it doesn't (you can try it on the third button). So I'm really not sure. If you think you know the answer as to why this happens, feel free to let me know. Otherwise, file this one under the "rare but interesting to know" category.
