GValidator Form Validation Library

Introduction

GValidator is a lightweight javascript form validation library that automatically adds client-side validation to form elements, without needing to write a single line of javascript.

The aims of the project are to provide the following:

A user-friendly experience
A reusable and lightweight library
Semantically clean code
Web Standards compliant code
Cross browser compatibility
Code flexibility and extensibility
Promote adoption via ease of use

To use the library without customization, all you need to do is include it.

Other features:

Easy Internationalization
Simple plug-in mechanism for new validators, should you want to extend functionality
Easily configurable
No dependencies on other libraries such as JQuery, Mootools etc.
