jQuery AddClass then removing a class

Question

In my Rails application, I send an Ajax request when the user hits the Save button, when it sends the request, I can return some jQuery.

What I\'d like to do is add

Answer 1

If someone needs more than one adding/removing of the class, .dequeue(); is also requered to function properly.

$('.button').addClass('saving').delay(2000).queue(function(){
   $(this).removeClass('saving'); 
   $(this).dequeue();
});
