Hi Guys!

Iam generating some radio buttons dynamically .

How to know how many radio buttons are there in the form.

for example i got 9 radio buttons (ie i know the total number).then i can go for the below code

(var i=0;i<9;i++)
{
if((document.form.r1.checked == true))
{
alert("something"
}
}

if i don't know the total numbers how to find the total numbers

help me guys....

  var binFlag = false;
  var lenRad = document.frmForm.radTest.length - 1;
  for (var rad=0; rad<=lenRad; rad++){
   if (document.frmForm.radTest[rad].checked){
    alert(&quot;You checked choice number &quot; + document.frmForm.radTest[rad].value + &quot;.&quot;);
    binFlag = true
   }
