I think you mean jQuery although you didn't clarify.

You can use this to get the zero based index:

$(":radio:checked").index()

You may combine it with any parent selectors. For example:

$("form :radio:checked").index()

$(".checkout :radio:checked").index()

$("#registerForm").find(":radio:checked").index()

Index!!!!!!

as I know Radio Btns (RB) are grouped...

so let's say you have3 RB, all of them should have the same  group, and each of them has a value and ID.

You check which one is checked and you get the value.

Or maybe am not getting your question correctly....
