You can get either current value or selected index:

JavaScript

sel = document.getElementById("Select2");
value = sel.value;
index = sel.selectedIndex;
//use whatever you want

As to the select onchange, it is invoked when you press Enter or click on selected item, not when you change the selection, which a is pretty reasonable thing.
