Detecting idle time in JavaScript elegantly
In a web application that I'm developing, on every page of the application, when nothing happens for a set amount of time, the page should automatically change. I think setting window.location will do for the latter part.
However, when it comes to detecting that nothing has happened, I'm a bit stuck. I'd think that binding all keyboard and mouse events to a single handler could do it, but I'm wondering if there is a better way. Has anyone done this before?
Detecting idle time in JavaScript elegantly seems to miss the blur and focus events on the window. The basic approach is as you suggested but I'd take a close look at which events exactly you're binding on.
