Validatious is an unobtrusive JavaScript that allows you to easily add form validation. Validatious does not requires any JavaScript library; however if you’re using one, it can easily work with it. It is cross browser and has been tested to work on IE6+, Firefox 2.0+, Opera 9.5+, Safari 3.0+, Chrome.
You can use it to validate forms with semantic HTML and/or a simple JavaScript DSL. Validatious has multilingual support and easily extensible (i.e., adding custom validators) with only a couple of lines of JavaScript. Several settings allow you to control how and when Validatious does validation, how it displays errors and more. If configuring isn’t enough, callbacks and easy overriding gives you complete control.
Validatious is written by Christian Johansen. The standalone version gratefully uses Dean Edwards’ addEvent and Base as well as addDOMLoadEvent, created by Jesse Skinner, Dean Edwards, Matthias Miller and John Resig.
Validatious is offered with a BSD License, which means you can use it for whatever you want to, however you want to. You can find further information, demo, documentation & download on Validatious Website.
