syntax prob- retrieve & submit value from function

[JonathanG6SWJ]

Hi Guys.
I've played with the syntax below so much I've forgotten what I've tried and what I haven't. So I thank you in advance for keeping me sane. I am trying to retrieve the index value for the option box.

Here's the function

<script type="text/javascript">
function getIndex()
{
var x=document.getElementById("mySelect")
}
</script>

Here's an example of my option box

<select name="J" id="mySelect" >
	<option value="a">a</option>
	<option value="b">b</option>
	<option value="c" selected>c</option>
	</select>

Here's my submit code

<input type="hidden" name="Result" value="<%= getIndex()% >">

Basically I can't get the value="<%= getIndex()%>"> bit of code to work

Many thanks in advance
Jonathan

It looks like the getIndex() is not actually returning anything. What if you write it like this:

function getIndex()
{
  return(document.getElementById("mySelect"));
}

Also, unless you are using server-side javascript then this is not going to work because a client side function doesn't run while the ASP is processing.
