How do I find out which DOM element has the focus?

Question

I would like to find out, in JavaScript, which element currently has focus. I\'ve been looking through the DOM and haven\'t found what I need, yet. Is there a way to do this

Answer 1

As said by JW, you can't find the current focused element, at least in a browser-independent way. But if your app is IE only (some are...), you can find it the following way :

document.activeElement

EDIT: It looks like IE did not have everything wrong after all, this is part of HTML5 draft and seems to be supported by the latest version of Chrome, Safari and Firefox at least.
