Foul
Foul is a JavaScript based, form validation language released under GPL so it's free to use and modify as long as the license stays intact. If you're familiar with the huge Netscape FormChek.js file which is sometimes used on forms, then you already know what Foul does. Foul contains a full language parsing engine which compiles advanced conditions and tests for the fields of a form. My goal is to have this script completely mirror the range of tests that FormChek.js does but in a much easier, cleaner and quicker way.
