A reasonably sized (12kb uncompressed, 6.8kb minified) form-validation plugin.
Actually it would only be 7 kb uncompressed, and 3.8kb minified, but the
email address and url validator regexps are ginormous (you could easily remove
them if you want to use a lighter regexp).

Usage

okValidate favors convention over configuration. To validate a particular field,
add a class to the field name of one or more validators.

<input class='email required' name='email' type='text' />

This will validate the field with the 'required' and 'email' validators (built-in).

To add additional validators you must add properties to or extend the
$.fn.okValidate.validators object and/or the $.fn.okValidate.messages
object. In order to properly validate, both the validator, and corresponding
messages must have the same key.

jquery.ajaxContactForm is a plugin made to simplify te sending of a inquiryform. The plugin gathers all the filled out data, after testing it on: required values, required numberical values and/or required e-mail structure. After that it sends the form via AJAX (JavaScript).

The forms that will be send are protected against spam because:

• There is no form-tag in the DOM, spam-bots can't see that the data will be send, let alone with what page/script it will be send;
• A field -invisible for human visitors- will be added which may not be filled out, spam-bots like to fill out as much as they can.

Feedback is a jQuery plugin that lets you send Feedback messages to a user after any event you choose. You can use it for custom error message handling, for example. So if you write some custom script to perform either a client or server-side validation, you can use Feedback to send an error message. Or, you can send informational messages. It uses the jQuery UI plugin to determine the default styles of the informational and error messages, so it is dependent on that plugin. It has properties that make it easy to position a feedback message next to an existing page element. You can specify a period of time in seconds for the message to appear before it fades away.
