商业源码 C#获取服务器时间??急急急请高手帮忙..
唉,花了点时间,现做了一个,你把下面的代码保存为ASPX就可以运行了,我已经测试通过
<form runat=server>
下面这个Hidden变量用来暂存服务器时间
<input name="ServerTime" type="hidden" value="<%=DateTimeNowToString("yyyy-MM-dd HH:mm:ss")%>">
<input name="divCurrentUser" type="text" style="width:300px;border:0" readonly>
</form>
<script language=javascript>
getServerTime();
//计算当前服务器时间
function getServerTime()
{
//取得要进行显示的日期
var datetimeYou = documentgetElementById('ServerTime')valuesplit(" ");
var yout1 = datetimeYou[0]split("-");
var yout2 = datetimeYou[1]split(":");
var nowY = parseFloat(yout1[0]);
var nowM = parseFloat(yout1[1]);
var nowD = parseFloat(yout1[2]);
var h = parseFloat(yout2[0]);
var m = parseFloat(yout2[1]);
var s = parseFloat(yout2[2]);
var daysMonth = new Array(31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31);
if(leapyear(nowY))
daysMonth[1] += 1;//闰年,2月加1
s = s + 1;
if (s >= 60)
{
s = 0;
m = m + 1;
if (m >= 60)
{
m = 0;
h = h + 1;
if (h >= 24)
{
h = 0;
nowD += 1;
if(nowD > daysMonth[nowM-1])
{
nowD = 1;
nowM += 1;
if(nowM > 12)
{
nowM = 1;
nowY += 1;
}
}
}
}
}
if (nowM < 10) nowM = "0" + nowM;
if (nowD < 10) nowD = "0" + nowD;
if (h < 10) h = "0" + h;
if (m < 10) m = "0" + m;
if (s < 10) s = "0" + s;
documentgetElementById('ServerTime')value = nowY + "-" + nowM + "-" + nowD + " " + h + ":" + m + ":" + s;
var today,hour,second,minute,year,month,date;
var strDate ;
//注意:Javascript中的月要减1,比如现在4月,要写成3
today=new Date(yout1[0],yout1[1]-1,yout1[2],yout2[0],yout2[1],yout2[2]);
var n_day = todaygetDay();
switch (n_day)
{
case 0:{
strDate = "星期日"
}break;
case 1:{
strDate = "星期一"
}break;
case 2:{
strDate ="星期二"
}break;
case 3:{
strDate = "星期三"
}break;
case 4:{
strDate = "星期四"
}break;
case 5:{
strDate = "星期五"
}break;
case 6:{
strDate = "星期六"
}break;
case 7:{
strDate = "星期日"
}break;
}
year = todaygetFullYear();
month = todaygetMonth() + 1;
date = todaygetDate();
hour = todaygetHours();
minute =todaygetMinutes();
second = todaygetSeconds();
if(month<10) month="0"+month;
if(date<10) date="0"+date;
if(hour<10) hour="0"+hour;
if(minute<10) minute="0"+minute;
if(second<10) second="0"+second;
documentgetElementById('divCurrentUser')value = "当前时间:" + year + "年" + month + "月" + date + "日 " + strDate +" " + hour + ":" + minute + ":" + second; //显示时间
setTimeout("getServerTime()",1000)
}
//判断参数是否闰年
function leapyear(year){
if(!/[^0]\d+/test(year)){
//通过正则判断年份的合法性
return false;
}
if(0==year)
return true;
if ( ((0==year%4) && !(0==year%100)) || (0==year%400) ){
return true;
}else{
if(year!=0)
return false;
}
}
</script>
初始化你的JLabel ，实例化new 就可以了。
同时你的程序有个比较严重的问题，那就是线程是否安全，swing不是线程安全的，你在一个新开的线程中更新GUI可能会报错，虽然这样的可能性很低，但是如果你要严谨的话，在你的线程中添加如下代码
SwingUtilitiesinvokeAndWait(new Runnable() {
public void run() {
displayAreasetText(dateFormatterformat(CalendargetInstance()getTime()));
}
});
