Hi guys, I've got the code below. Please can you show me how I could make only visible radio buttons required/mandatory. If say, I chose 'Pros', every radio buttons under it should be required/mandatory and everything under 'Testr' are not required/mandatory since they not visible.

Thanks for any help.

Code: 
<html>
<head>
<script type="text/javascript" language="javascript"><!--
function VF_refform(){
var theForm = document.forms['refform'];
var rFlg_TestTmr = false;
var rFlg_NonPainfulLrg = false;

var rFlg_ProsFelsMal = false;
var rFlg_condition = false;
var errMsg = "";
var setfocus = "";

for(var r5=0;r5<theForm['TestTmr'].length;r5++){if(theForm['TestTmr'][r5].checked)rFlg_TestTmr=true;}
for(var r4=0;r4<theForm['NonPainfulLrg'].length;r4++){if(theForm['NonPainfulLrg'][r4].checked)rFlg_NonPainfulLrg=true;}

I would recommend you use the required function. You could use jquery to modify the child attributes to include required. Something along the lines of the below if clause. The purpose would be to check if Pros is set to true, and if so, then add the required attribute to the NonPainfullLrg. You would have to add logic to remove the required field if changed to false.

if (document.getElementById("Pros").checked = true) {
$("NonPainfullLrg").attr("required", true);
}


Result:

<td valign="middle"><input type="radio" name="NonPainfulLrg" id="NonPainfulLrg" value="1" required></td>

Hi tacohunter, can this still be achieved without using jquery? If yes, how? Thanks.

Yes, absolutely. Below is tested code, but not 100% complete. Please have a look at the screenshot which shows what happens if you choose only 1 option and try to click submit.
