Question

I’m looking to learn how to build something that detects key-presses in order to throttle a function.

Something like:

var LastKeyPress;
function hitTheServer() {
 if LastKeyPress > 2 seconds ago {
    hit the server and do stuff
   LastKeyPress = now();
 }
}

What do you think? Maybe this is built into jQuery? Also, its something that I’d likely use for many functions, and it could be interesting to have this working globally, so I can use less code and apply to several functions. Thoughts?

Thanks
