validate form

**darren9** · 07-15-2008, 04:42 AM

Hi everyone, i have to validate a form for a client, i have it working apart from two sections.

Do you require transportation? yes or no
Do you require installation? yes or no

when clicked yes a new div appears "divtxta", i need this div to be validated when yes is checked but not to be validated when no is checked.

If anyone can help i would really appreciate it.

</SCRIPT>
<!-- End DI Tracking Code -->
<script language="JavaScript">
function showhide(inval,divid)
{
if(inval=="yes")
{document.getElementById(divid).style.visibility=" visible"}
if(inval=="no")
{
document.getElementById(divid).style.visibility="h idden"
document.contact.txta.value="Enter your reason here"
}
}

function showhide(tranval,divid)
{
if(tranval=="yes")
{document.getElementById(divid).style.visibility=" visible"}
if(tranval=="no")
{
document.getElementById(divid).style.visibility="h idden"
document.contact.txta.value="Enter your reason here"
}

I am also using a JavaScript to validate the form "gen_validatorv31.js"
that i got from http://www.javascript-coder.com/html...lidation.phtml

Many Thanks

Hi Darren,

why not use an onsubmit="extra_validation(contact)" in the form tag, then in this function check each radio set in turn to see if set to yes, if so, add in frmvalidator.addValidation("location","maxlen=250");

Ok nevermind this I've just read the tutorial on your validation script. I'm guessing you haven't read it right the way through because it answers your question. Check this out: http://www.javascript-coder.com/html...n.phtml#custom
