No value for radio button

[beco73]

Hi,

I don't know why i don't get any value for radio buton. I get 'undefined' in the alert. i was wondering do you see anything wrong with the code?

thanks

<tr>

<td><input type='radio' name='buyrent' value='0' checked >&nbsp;<strong>Buy</strong>
</td>

<td><input type='radio' name='buyrent' value='1' >&nbsp;<strong>Rent</strong>
</td>

</tr>

<script language="JavaScript" type="text/javascript">
function validate()
{
h=document.search.buyrent.value;
alert(h);
}
</script>

yes - multiple elements that share a name (such as radios) are referenced using array notation, so you have to do something like

<script language="JavaScript" type="text/javascript">
function validate()
{
 if (document.search.buyrent[0].checked) {
  h = document.search.buyrent[0].value;
  alert(h);
 }
}
</script>
