Creating dynamic feedback

[Andrea Baric]

I am trying to create an application that mirrors a multiple choice test with just one question per page. How do I check for the correct answer and generate instant visual feedback--right or wrong-- after a user has submitted his or her answer (via a radio button)?

i think you can use validation on form level, to check or validate the answer of the form submitted.

Or if you don't want a full page reload, you could submit and return the response via Ajax.
