这个有关问题如何解决_ASP.NET

这个问题怎么解决
要在ASPX页面上显示动态时间。精确到秒
有代码更好

------解决方案--------------------------------------------------------
<script type="text/javascript">

function getDateTime(){

var date = new Date();//取得当期日期

var dateStr=date.toLocaleString() +" ";//把当前日志转化为本地日期

dateStr += "星期"+'日一二三四五六'.charAt(date.getDay());//取得星期并格式化

document.getElementById('activeDateTime').innerHTML=dateStr;//把时间显示到activeDateTime上

}

setInterval("getDateTime()",1000);//间隔时间更新时间

</script>
------解决方案--------------------------------------------------------
请使用JS处理

JScript code

// 本地时钟function clockon() {    var now = new Date();    var year = now.getFullYear(); // getFullYear getYear    var month = now.getMonth();    var date = now.getDate();    var day = now.getDay();    var hour = now.getHours();    var minu = now.getMinutes();    var sec = now.getSeconds();    var week;    month = month + 1;    if (month < 10)        month = "0" + month;    if (date < 10)        date = "0" + date;    if (hour < 10)        hour = "0" + hour;    if (minu < 10)        minu = "0" + minu;    if (sec < 10)        sec = "0" + sec;    var arr_week = new Array("星期日", "星期一", "星期二", "星期三", "星期四", "星期五", "星期六");    week = arr_week[day];    var time = "";    time = year + "年" + month + "月" + date + "日" + " " + hour + ":" + minu            + ":" + sec + " " + week;    $("#bgclock")(time);    var timer = setTimeout("clockon()", 1000);
------解决方案--------------------------------------------------------
function display()   //时间
{
	var d=new Date();
	var year=d.getFullYear();
	var month=d.getMonth()+1;
	var day=d.getDate();
	var hour=d.getHours();
	var minu=d.getMinutes();
	var sec=d.getSeconds();
	if(minu<10)
	{
		minu="0"+minu;
	}
	if(sec<10)
	{
		sec="0"+sec;
	}
	if(hour<12)
	{
		str="AM";
	}
	else
	{
		str="PM";
	}
	document.getElementById("time").value=year+"年"+month+"月"+day+"日 "+hour+":"+minu+":"+sec+" "+str;
	setTimeout("display()",1000);
}

调用位置
<body onLoad="display()">
