getelemenbyId not working for radio buttons

shane3341436
Hello to all.
I used following html code to view a number of groups of radio button
Expand|Select|Wrap|Line Numbers
  1. <td><input name="f1_<?=$rs["Id"]?>" id="f1_<?=$rs["Id"]?>" type="radio" value="1"  /> Yes</td>
  2. <td><input name="f1_<?=$rs["Id"]?>" id="f1_<?=$rs["Id"]?>" type="radio" value="0"   /> No</td>
while submitting form I used javascript to get the value of the radio button and store that in a hidden field which is then submitted.
I used getelementbyId like
Expand|Select|Wrap|Line Numbers
  1. f1=document.getElementById("f1_"+no).value
but it always returns value 1.Please somebody help me

IDs should be unique. It's just getting the value of the first element. Use getElementsByTagName to get the array of radio buttons and then check the "checked" property for each to see which one is currently selected.
