Question on dynamically generated radio buttons

[Saathvik Reddy]

Hi,
I have a JSP page which generates the name of the radio button dynamically.
My code in JSP:

<html:radio property = '<%=question.getOid()%>' value =
"<%=qvalue.getOid()%>" onklick="showRadioLayer(this)"/>

This JSP code generates 2 radio buttons with the same name(radio group) but with different values.

My code in Java Script:

function showRadioLayer(id){
var a = id.name; // I can get the name of the radio button with this
var len = document.form.a.length //I want to get length of radio group
but i cant get the length. I know this is wrong but how do i get the length of the radio group.

Please help me,
Thanks

because you are not referecing it right...

var len = document.form.elements[a].length;
