Retrieving selected value of drop down

[mangocinn]

Need help...
How can I retrieve the selected value of a drop down before hitting submit. I need to find out the selection so that I can limit the options in another drop down in the same form.
Please help...

Eg:

<script language='JavaScript'>
function visit(newURL) {
if (newURL != &quot;&quot {
location.href=newURL
}
}
</script>


<form>
<select onchange=visit(this.options[selectedIndex].value)>
<option selected value=&quot;&quot;>Pick search engine
<option value='
