  </head>
  <body>
   <input type="text" name="mss" id="mss"/>
   <form action="./index.html">
    <input type="text" value="name" name="name"/>  
   </form>
  <body>
</html>
<script type="text/javascript">
<!--
  window.onload=function(){
    daojishi();
   }
   var counttime=120*60;//总秒钟
   function daojishi(){
   if(counttime>=0){
       var ms = counttime%60;//余数 89%60==29秒
       var mis = Math.floor(counttime/60);//分钟
       if(mis>=60){
       var hour=Math.floor(mis/60);
       mis=Math.floor((counttime-hour*60*60)/60);
       document.getElementById("mss").value=hour+"小时"+mis+"分"+ms+"秒数";
       }else if(mis>=1){
       document.getElementById("mss").value=mis+"分"+ms+"秒数"; 
       }else{
       document.getElementById("mss").value=ms+"秒数"; 
       }
       counttime--;
       vartt = window.setTimeout("daojishi()",1000);
  }else{
    window.clearTimeout(vartt);
    window.confirm("考试时间结束,请单击提交"); 
    tijiao();
