 <script language=Javascript> 
  function time(){
    //獲得顯示時(shí)間的div
    t_div = document.getElementById('showtime');
   var now=new Date()
    //替換div內(nèi)容 
   t_div.innerHTML = "現(xiàn)在是"+now.getFullYear()
    +"年"+(now.getMonth()+1)+"月"+now.getDate()
    +"日"+now.getHours()+"時(shí)"+now.getMinutes()
    +"分"+now.getSeconds()+"秒";
    //等待一秒鐘后調(diào)用time方法，由于settimeout在time方法內(nèi)，所以可以無(wú)限調(diào)用
   setTimeout(time,1000);
  }

<body  onload="time()">
