http://bassistance.de/jquery-plugins/jquery-plugin-validation/ looks to be the best jquery validation plugin out there. I can\'t seem to get it working in the jQuery UI dial
I have recently created a plugin for HTML Form validation. You can try it yourself.Prashant-UI-Validator
Build using Jquery, supports Bootstrap and you can configure it in your way. It supports different data types like INT, STRING, NUMERIC, MAX[Num], MIN[Num],EMAIL and most importantly your custom javascript validation code as well.
Hope it helps,
