页面动态显示时间

 1.客户机时间(简单)
<body>
<span id="aa1"> </span>
<script>
  showTime();
  function showTime(){
    var now = new Date();
    document.getElementById("aa1").innerHTML=now.getHours()+":"+now.getMinutes()+":"+now.getSeconds();
    setTimeout("showTime()",1000);
  }
</script>
</body>
2.服务器时间(也不难)
<%@ page language="java" import="java.util.*" contentType="text/html;charset=GBK" %>
<html>
<body>
<span id="aa1"> </span>
<script>
  var now = new Date();
  now.setTime( <%=new Date().getTime()%>);
  showTime();
  function showTime(){
    document.getElementById("aa1").innerHTML=now.getHours()+":"+now.getMinutes()+":"+now.getSeconds();
var c=now.getTime();
c+=1000;
now.setTime(c);
    setTimeout("showTime()",1000);
  }
</script>
</body>
</html>
