How to detect idle time in JavaScript elegantly?

Question

Is it possible to detect \"idle\" time in JavaScript?
My primary use case probably would be to pre-fetch or preload content.

Idle time:

Answer 1

Just a few thoughts, an avenue or two to explore.

Is it possible to have a function run every 10 seconds, and have that check a "counter" variable? If that's possible, you can have an on mouseover for the page, can you not? If so, use the mouseover event to reset the "counter" variable. If your function is called, and the counter is above the range that you pre-determine, then do your action.

Again, just some thoughts... Hope it helps.
