本人是给电视做系统，客户要求页面能显示时间，因为电视浏览器获取的时间不对，没办法只能从服务器获取时间，但是问题来了，服务器的时间获取一次就成静态的了，客户不满意，但也没办法，只能这样。不过这个问题在我这老惦记着，今天看到有个例子，说把java获取服务器的时间转化成毫秒，然后用js每一秒刷新一次就可以动态显示，所以就有了下面的
复制代码 代码如下:
<%@ page language="java" import="java.util.*" pageencoding="utf-8"%>
<%@page import="java.text.simpledateformat;"%>
<%
string path = request.getcontextpath();
string basepath = request.getscheme()+"://"+request.getservername()+":"+request.getserverport()+path+"/";
%>
<!doctype html public "-//w3c//dtd html 4.01 transitional//en">
<html>
<head>
<base href="<%=basepath%>">
<title>my jsp 'index.jsp' starting page</title>

<body>
<%
calendar rightnow = calendar.getinstance();
simpledateformat format = new simpledateformat("yyyy-mm-dd hh:mm");
%>
<script language="javascript">
//从服务器上获取初始时间
var currentdate = new date(<%=new java.util.date().gettime()%>);
function run()
{
currentdate.setseconds(currentdate.getseconds()+1);
var time = "";
var year = currentdate.getfullyear();
var month = currentdate.getmonth() + 1;
var day = currentdate.getdate();
var hour = currentdate.gethours();
var minute = currentdate.getminutes();
var second = currentdate.getseconds();
if(hour < 10){
time += "0" + hour;
}else{
time += hour;
}
time += ":";
if(minute < 10){
time += "0" + minute;
}else{
time += minute;
}
time += ":";
if(second < 10){
time += "0" + second;
}else{
time += second;
}
document.getelementbyid("dt").innerhtml = year+"年"+month+"月"+day+"日" + time;
}
window.setinterval("run();", 1000);
</script>
<div id="dt">自动显示时间。。。。</div>
