Really easy field validation with Prototype I wanted a robust javascript validation library that was simple to implement and didn't require me do any extra work other than creating the form.

There are a few javascript libraries that implement that idea like wForms, but, since I'm currently hell-bent on re-writing all my javascript using Prototype, I thought I'd see how difficult or easy it would be to roll my own. Turns out that this is just the sort of thing that is easy with Prototype. [Updated Again!] : new version 1.2! ( also, A bit of maintenance: version 1.2.1)
