ASP.NET时间问题

Question

请问asp.net C# 如何显示时间 要秒跳动显示的那种？

Answer 1

这个用js就能实现了，跟asp.net 没关系。
setInterval(showtime, 1000);
function showtime() {
            var time = new Date();
            document.getElementById('show1').innerHTML = time.getFullYear() + '年' + (time.getMonth() + 1) + '月' + time.getDate() + '日';           //显示年、月、日
            document.getElementById('show2').innerHTML = ' 星期' + '日一二三四五六'.charAt(time.getDay());             //显示星期
            document.getElementById('show3').innerHTML= (time.getHours()>9?time.getHours():'0'+time.getHours()) + ':' + (time.getMinutes()>9?time.getMinutes():'0'+time.getMinutes())+ ':' + (time.getSeconds()>9?time.getSeconds():'0'+time.getSeconds());           //显示时间
        }

 <div id="showtime" style=" text-align:left;float:left;margin-top:10px;width:220px;height:20px; line-height:20px;overflow:hidden;color:#FFFF99;">今天是
        <script language="javascript" type="text/javascript">
                                var enabled = 0; today = new Date();
                                var date;
                                if(today.getDay()==0) day = "星期日 "
                                if(today.getDay()==1) day = "星期一 "
                                if(today.getDay()==2) day = "星期二 "
                                if(today.getDay()==3) day = "星期三 "
                                if(today.getDay()==4) day = "星期四 "
                                if(today.getDay()==5) day = "星期五 "
                                if(today.getDay()==6) day = "星期六 "
                                document.fgColor = "FF0072";
                                date1 =today.getYear()+"年"+(today.getMonth() + 1 ) + "月" + today.getDate()+"日 ";
                                date2 = day ;
                                document.write(date1);
                                document.write("<font id='clock' style='font-size:12px;'></font>");
                                var now,hours,minutes,seconds,timeValue;
                                function showtime(){
                                now = new Date();
                                hours = now.getHours();
                                minutes = now.getMinutes();
                                seconds = now.getSeconds();
                                timeValue = (hours >= 12) ? " " : " ";
                                timeValue += hours+ ":";
                                timeValue += ((minutes < 10) ? "0" : "") + minutes + ":";
                                timeValue += ((seconds < 10) ? "0" : "") + seconds + "";
                                clock.innerHTML = timeValue+"    "+day;
                                setTimeout("showtime()",100);
                                }
                                showtime();
                             </script>
        </div>

js的方法上面都说了，还有一个就是用Ajax的控件，UpdatePanel+Timer实现，easy！
