jQuery jQuery throttle / debounce: Sometimes, less is more!

http://benalman.com/projects/jquery-throttle-debounce-plugin/

Version: 1.1, Last updated: 3/7/2010

jQuery throttle / debounce allows you to rate-limit your functions in multiple useful ways. Passing a delay and callback to $.throttle returns a new function that will execute no more than once every delay milliseconds. Passing a delay and callback to $.debounce returns a new function that will execute only once, coalescing multiple sequential calls into a single execution at either the very beginning or end.
