[Javascript] Noob - JS/XHTML 1.1/Forms

[Shawn Milo]

Do something like this:

var x = 0;
var radioCount = 0;
for (x=0; x < document.elements.count; x++){

   if (document.elements[x].type = 'radio'){

      radioCount += 1;
  }


}


This is untested, and I'm sure that there are flaws in the syntax. But
try it out, and check Google Groups to fill in the gaps. I'm not
taking the time to make this work partially because I'm doing other
things, and partially because if you are relatively new, it will be a
learning experience for you.
