这个JS函数怎么显示日期呢？在页面里什么都没有了还报错，说没有声明time<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Top.aspx.cs" Inherits="admin_Top" %><!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><html xmlns="http://www.w3.org/1999/xhtml">

year=now.getYear();
month=now.getMonth()+1;
date=now.getDate();
hours=now.getHours();
minutes=now.getMinutes();
seconds=now.getSeconds();

if(seconds<=9)
seconds="0"+seconds
time.innerHTML=year+"年"+month+"月"+date+"日"+" "+hours+":"+minutes+":"+seconds;setTimeout("show()",1000);
}
show();
</script>
div不能放在td里，怎么能获得时间值呢
只要js在后面（相对于<div id=time></div>）直接time.innerHTML或者document.getElementById("time").innerHTML都可以获取到，楼主的程序就是顺序的问题

还真是顺序问题，放在后面就可以了，但是一编译就报TD中不能有DIV，我怎么替换呢，你写的那个我应该放在那里呢
除了用DIV id=time 这样获得time的值还有什么办法吗？

这个添加id <td align="right" style="width: 650px; height: 18px;" id="time">
