<P>Here's a form validation script that is very easy to use.</p> <P>Current Version: 1.5.4.1 - 06 Jan 2007 - 
<A href="http://tetlaw.id.au/upload/dev/validation/" title="Really Easy Field Validation demo">Demo</A> / 
<A href="http://tetlaw.id.au/upload/dev/validation/validation1.5.4.1.zip" title="Download the demo zip file">Download</A></p> <H2>Instructions
</H2>
<P>The basic method is to attach to the form's 
<CODE>onsubmit</CODE> 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.</P></blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://tetlaw.id.au/view/javascript/really-easy-field-validation"><P>Here's the list of classes available to add to your field elements:</p> <UL>
