You'll want to take a look at client_side_validations gem. This integrates, rails, jQuery, server and client side validation: https://github.com/bcardarella/client_side_validations

Ryan Bates has a good screencast on this topic: http://railscasts.com/episodes/263-client-side-validations

got to about 4 minutes into the video, where he does an ajax request to validate the uniqueness of a username in the database.

and browse the source of his example http://github.com/railscasts/episode-263
