jQuery realtime form validation

Question

I am currently using $.blur(fn();) for form validation, but this only takes effect when the form field loses focus. Is there a way of doing it on keypress to get realtime validation? I suppose I could do the 'poll all fields every second' approach, but I am sure there must be a more elegant way?

Answer 1

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

I would recommend change or keypress or keydown.

Answer 2

You can use $.keyup

Answer 3

Since your using jQuery you should look into the jQuery Validation Plugin. It will take care of the events for you. :)

Answer 4

I hope this plugin helps
