JQuery real-time validation

Question

I am currently using $ .blur (fn ();) to validate the form, but this only works when the form field loses focus. Is there a way to do this when I press a key to get real-time confirmation? I suppose I could use "polling all the fields every second," but I'm sure there should be a more elegant way?

Answer 1

You can use $ .keyup

Answer 2

There are many other events that you could use. See here: http://docs.jquery.com/Events

I would recommend changing or pressing a key or pressing a key.
