jQuery Validation Engine with Demo

jQuery Validation Engine with Demo

jQuery validation engine is a Javascript plugin aimed at the validation of form fields in the browser (IE 6-8, Chrome, Firefox, Safari, Opera 10). The plugin provides visually appealing prompts that grab user attention on the subject matter.

Validations range from email, phone, and URL, to more complex calls such as ajax processing or custom javascript functions. Bundled with many locales, the error prompts can be translated into the language of your choice.
Rules of thumb
* field.id are **unique** across the page
* for simplicity and consistency field.id and field.name should match (except with minCheckbox and maxCheckbox validators)
* spaces or special chars should be avoided in field.id or field.name
* use lower cases for input.type ie. *text, password, textarea, checkbox, radio*
* use the Ajax validator last ie. validate[custom[onlyLetter],length[0,100],**ajax[ajaxNameCall]**]
* use only one Ajax validator per field!
* JSON services should live on the same server (or you will get into browser security issues)
* in a perfect RESTful world, http **GET** is used to *READ* data, http **POST** is used to *WRITE* data: which translates into -> Ajax validations should use GET, the actual form post should use a POST request.
