[jQuery] Threshold for saving <textarea> content with AJAX
Confusing title, but what I'm looking for can't really be summed up in
a sentence [ bonus points if you can ].
Basically I have a onkeyup binded to a <textarea>, and the function
the onkeyup calls sends the data to the server to be saved. I'm
wondering if a method to only send the data when you stop typing
exists. So basically you can be typing a paragraph quickly, and it
*won't* call the function, but once you stop typing [say 5 seconds
after the last key up], the function is called. What I think would be
the best [and possibly only] way to achieve this, is to check the
last time the function was called, and do a setTimeout() for 5
seconds, and when this check function is called again, it clears the
timeout and starts it again. Is there any other way?
