系统时间一般是值服务端时间,js获取服务端时间的方法是直接用ajax获取。
编写显示时间的页面:
<html>
<head>
<meta http-equiv="Content-Type" content="text/htmlcharset=utf-8" />
<title>Server date/time</title>
<script language="javascript" src="serverDate.js"></script>
</head>
<script language="javascript">
var localTime = new Date()
document.write("Local machine time is: " + localTime + "<br>")
document.write("Server time is: " + date)
</script>
<body>
</body>
ajax脚本获取server的时间
var xmlHttp
function srvTime(){
try {
//创建xmlHttp对象
xmlHttp = new XMLHttpRequest()
}
catch (err1) {
//ie浏览器
try {
xmlHttp = new ActiveXObject('Msxml2.XMLHTTP')
}
catch (err2) {
try {
xmlHttp = new ActiveXObject('Microsoft.XMLHTTP')
}
catch (eerr3) {
//ajax不支持
alert("AJAX not supported")
}
}
}
//打开xmlHttp请求
xmlHttp.open('HEAD',window.location.href.toString(),false)
//设置xmlHttp请求头
xmlHttp.setRequestHeader("Content-Type", "text/html")
//发送请求
xmlHttp.send('')
// 获取response中的Date参数
return xmlHttp.getResponseHeader("Date")
}
var st = srvTime()//服务器时间赋值给st变量
var date = new Date(st)//转换js的date对象
// 输出服务器时间
document.write("服务器时间: " + date)
拓展资料:JavaScript一种直译式脚本语言,是一种动态类型、弱类型、基于原型的语言,内置支持类型。它的解释器被称为JavaScript引擎,为浏览器的一部分,广泛用于客户端的脚本语言,最早是在HTML(标准通用标记语言下的一个应用)网页上使用,用来给HTML网页增加动态功能。
语句:JavaScript程序是由若干语句组成的,语句是编写程序的指令。JavaScript提供了完整的基本编程语句,
它们是:赋值语句、switch选择语句、while循环语句、for循环语句、for each循环语句、do...while循环语句、break循环中止语句、continue循环中断语句、with语句、try…catch语句、if语句(if..else,if…else if…)。

拷贝下来试试! 行的话给分啊 呵呵:)
楼主用的什么变成语言啊?如果是ASP,NET就很简单啊,我就是把这个脚本做成单独的页面,直接在其他页面调用的啊.如果是别的语言,你就把JS脚本函数弄过去.
JSP我没用过,把我这个页面直接弄过去,在其他页面调用不行吗?这个就是JS+HTML啊.应该可以吧.当需要调用的时候不调用脚本,调用这个网页,让程序弹出这个网页,设置网页的大小(就像弹出来一个小日历一样)就行.和我这的效果一样.
我照你说的改了改,不太好用,呵呵.只能帮这么多了,你看看吧.我可以担保给你的程序绝对可用.请别人帮着把我这个改了吧.谁改的好就给谁分吧:)
