Getting selected radio button value

This loops through all the radio buttons in the form ('myform' in this case but change to your form id) and adds the selected one to string in the form or querystring ...

<html>

<head>
<script language="javascript">
function getvalues()
{
var str = '?';
var elem = document.getElementById('myform').elements;
for(var i = 0; i < elem.length; i++)
{
if (elem.type == "radio" && elem.checked) {
str += elem.name + "=";
str += escape(encodeURI( elem.value));
}
}
// return(str);
alert(str);
}
</script>

</head>

<body>

<form id="myform" method="POST" action="">
<p>
<input type="radio" value="V1" name="R1"><input type="radio" value="V2" name="R1"><input type="radio" value="V3" name="R1"><input type="radio" value="V4" name="R1"><input type="radio" value="V5" name="R1"><input type="radio" value="V6" name="R1"><input type="radio" value="V7" name="R1"><input type="radio" value="V8" name="R1"><input type="radio" value="V9" checked name="R1"></p>
