If you add the following snippet to your Free Nodelet, you'll have a way to clear all the radiobuttons on the current page.
<script language="javascript"><!--
function clear_all_radios(){
var lb = "\x5B";
var rb = "\x5D"
var elements = document.getElementsByTagName('input');
var elnum;
for(elnum=0;elnum<elements.length;elnum++){
var el = eval("elements"+lb+"elnum"+rb);
if ( el.type == 'radio') {
el.checked = false;
}
}
}
//--></script>
<p><a href="javascript:clear_all_radios()">Clear All Radiobuttons</a><
+/p>
Thanks to jZed for the parent node, upon which this code is based.
