Cool. Thanks!

Have you tested this cross-browser at all? Is window.onfocus defined everwhere?

[dburles]

From what I've read yes. I'm just not sure about mobile devices, so I'll test that a bit and let you know

Cool. Want to add to the README and I'll merge and release?

I've read way too many stackoverflow posts regarding browser focus and it seems to be one of those things that's just difficult to do properly cross-platform.

This is the best one I found:
http://stackoverflow.com/questions/1060008/is-there-a-way-to-detect-if-a-browser-window-is-not-currently-active

Also there is a new API http://www.w3.org/TR/page-visibility/
The stackoverflow post above makes use of it but even so, I couldn't get it working on the ipad.

It seems a bit too loose to merge into the master version.

Hmm, yeah support is a bit patchy: http://caniuse.com/#feat=pagevisibility

Kind of a cool feature though. Is it better to have it where possible or not at all?

I'm not sure to be honest!
Like it's not really reliable enough to use for an absolute case of "yes this user is absolutely looking at the page right now" but the flip side is say one example, working nicely for displaying a nice visual "extra" in a chat app.

Hm…….. will ruminate
