    <html>
    <head>
    <meta http-equiv="content-type" content="text/html; charset=utf-8" />
    <title>selects</title>
    <style>
    body{color:#000;background-color:#fff;font-family:'Bookman Old Style',Georgia,Verdana;font-size:14px;text-align:center;padding-top:100px;}
    #res{text-align:center;padding:50px;}
    </style>
    <script>
    var last_active_sel_id='',last_selected_value='';
    function activateSelects(){
    var sels=document.getElementsByTagName('select');
    for(var i=0;i<sels.length;i++){
    sels[i].onclick=sels[i].onchange=function(){
    last_active_sel_id=this.id;
    last_selected_value=this.options[this.selectedIndex].value;
    document.getElementById('l_a_s_id').innerHTML='The last clicked select element id is <b>'+last_active_sel_id+'</b>';
    document.getElementById('l_s_val').innerHTML='The last selected value is <b>'+last_selected_value+'</b>';
    }
    }
    }
    window.onload=activateSelects;
    </script>
