Answer 1

create javascript function and put function in select box onchange event.

check working example on fiddle

<script>
 function changeTest(obj){
    alert(obj.options[obj.selectedIndex].value);
  }
</script>

 <select name="level" onChange="changeTest(this)">
   <option value="1" selected="selected">Administrator</option>
             <option value="2">Manager</option>
             <option value="3">HR Staff</option>
 </select>
