1、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>
2、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)
