Check this page http://www.webdevelopersjournal.com/articles/javascript_validate_form.html, but it is not an answer on your question. I remember, I put in Favorites page with explanations how to save user's inputs (I don't remember, was the validation client-side or server-side), but it was probably on another computer, I could not find it right now.
