I found this with google - http://jqueryfordesigners.com/using-ajax-to-validate-forms/

Seems to be a good one.

If you're testing something like a username, to see whether it exists (I assume this would be the reason for javascript) - Just format your response in a specific way ie

If username/email is ok: "OK", if not "FAIL" - then (my code is jQuery based because it's alot easier to write than straight javascript)

 $("input[name='emailAddress']").onblur(function() {
      $.ajax({
           url:"/checkemailaddress?email="+$(this).val(),
           success: function(response) {
                if(response=="OK"){
                     $(this).removeClass("RedCross").addClass("GreenTick");
                } else {
                     $(this).removeClass("GreenTick").addClass("RedCross");
                }

           }

      });

 });

Codes not tested by the way!
