Really easy field validation using AJAX

Really easy field validation from Dexagogo has implemented a solid form validation API. The basic method is to attach to the form’s onsubmit event, read out all the form elements’ classes and perform validation if required. If a field fails validation, reveal field validation advice and prevent the form from submitting.

The validator also avoids validating fields that are hidden or children of elements hidden by the CSS property display:none. This way you can give a field the class of ‘required’ but it’s only validated if it is visible on the form. The demo illustrates this.

Requirements: Any Modern Browsers with Javascript Enabled

Uni-Form for Standard Form Markup

Uniform is trying to standardize form markup (xhtml) and css, “modularize” it, so even people with only basic knowledge of these technologies can get nice looking, well structured, highly customizable, semantic, accessible and usable forms.

Plug and play style. Download the uni-form.zip and you’re pretty much all set! It is encouraged to edit css properties only in the uni-form.css file, so you can easily upgrade to the newer versions as they come along by copying over the old copy of the uni-form-generic.css.

Requirements: IE6+, Firefox 1.5.x+, Opera9.x+, Safari, Konqueror
