jVal

jVal is a lightweight form validator for jQuery developers to prevent useless client-server communications for false form submissions and feedback messages.

The plugin takes care of all form field input rules on the client side, only sending its data to the server when it complies to all of them.

A demo is included with the download package.

• Works with input and drop-down form elements
• Can work in real-time as the user types his data

What is new in this release:

• Many fixes, new layout and a demo with more features.

Requirements:

• JavaScript enabled on client side
• jQuery 1.2.6 or higher
