j Query Form Validator is a feature rich and multilingual j Query plugin that makes it easy to validate user input while keeping your HTML markup clean from javascript code.

Even though this plugin has a wide range of validation functions it's designed to require as little network traffic as possible.

The option of using pure HTML, sometimes with a touch of CSS, to complement Java Script form validation was until recently unthinkable.

Sure there have been all kinds of whacky plug-ins over the years aimed at achieving this, but never a single standard that we could work towards.

The simplest change you can make to your forms is to mark a text input field as 'required': This informs the (HTML5-aware) web browser that the field is to be considered mandatory.

Different browsers may mark the input box in some way (Firefox 4 Beta adds a red box-shadow by default), display a warning (Opera) or even prevent the form from being submitted if this field has no value.

Then use is Valid Container(container) method to determine the container is valid or not.
