Question

This has been asked here before, but several years ago, and there was no cross-platform solution at the time (other than the setTimeout solution, which is really not very handy).

I’d like to do onblur="foo(parm);" and have foo be able to determine which element now has focus.

I’m using regular javascript; no jQuery for this one, please.

Is that possible these days?

You can try something like this:

function whereDidYouGo() {
    var all = document.getElementsByTagName('*');

        for (var i = 0; i < all.length; i++)
            if (all[i] === all[i].ownerDocument.activeElement)
                return all[i];
}

EDIT:

function whereDidYouGo() { return document.activeElement; }
