Need to pass variable in Javascript to my ASP pgm

Expert Carrzkiss helped me with a bit of ASP 3.0 code in order to get my pgm to display a dropdown box populated with employees that the User is authorized to enter payroll time for (see Q_24240327).  A Javascript routine was used to capture the Empl ID associated with the selected employee.  Problem now is I need to pass that value to my ASP pgm...hopefully without leaving the page.
Is this possible to do?  Below is the relevant code.

<!-- Save the Selected Empl ID from the dropdown -->
    <script type="text/javascript">
    var strSelectedID;
	function showSelected(val){
		strSelectedID = val;
	    document.getElementById
        ('selectedResult').innerHTML = "Empl ID = "+strSelectedID;
	    }
    </script>
.
