If you're looking for a nice validation API that doesn't require jQuery, I've been working on one recently for forms: <a href="https://github.com/segmentio/validate" rel="nofollow">https://github.com/segmentio/validate</a><p>I personally really dislike working with jQuery plugins, because their APIs tend to be very poorly thought out. And using strings as a way to call methods is generally unfortunate, especially when they are snake-cased like these ones.
