In javascript how do I check which of a group of radiobuttons is checked?

this is the radiobutton group:

<input name="time_limit[]" id="time_limit[]" type="radio" value="no">
<input name="time_limit[]" id="time_limit[]" type="radio" value="yes">

I tried with:
var time_limit = document.getElementById("time_limit[]");
if (time_limit[1].checked)
...
and with
if (time_limit.value == "yes")

but none of these work

David...

Give this a shot - it works in both IE6 and FF, so it shouldn't give you any issues cross browser...with the possible exception of Safari.

<code>
<html>
<head>
<script type="text/javascript">
function rbCheck()
{
  var rb = document.getElementsByName("rblist");
  for (var i = 0; i < rb.length; i++)
  {
   if (rb[i].checked)
   {
    alert("Checked: " + rb[i].value);
   }
  }
}

</script>
</head>
<body>
<p>
<input name="rblist" type="radio" value="Radio Button 1" />
Button 1</p>
<p>
<input name="rblist" type="radio" value="Radio Button 2" />
Button 2</p>
<p>
<input name="rblist" type="radio" value="Radio Button 3" />
Button 3</p>
<br />
<input id="btnShowChecked" type="button" value="Show Checked" onclick="rbCheck()" />

</body>
</html>
</code>
