js动态时间

一.在<head></head>

之间写入下面js代码

<script type="text/javascript" language="JavaScript">
var timerID = null
var timerRunning = false
function MakeArray(size) {
this.length = size;
for (var i = 1; i <= size; i++) {
this[i] = "";
}
return this;
}
function stopclock() {
if (timerRunning)
clearTimeout(timerID);
timerRunning = false
}
function showtime() {
var now = new Date();
var year = now.getYear();
var month = now.getMonth() + 1;
var date = now.getDate();
var hours = now.getHours();
var minutes = now.getMinutes();
var seconds = now.getSeconds();
var day = now.getDay();
Day = new MakeArray(7);
Day[0] = "星期天";
Day[1] = "星期一";
Day[2] = "星期二";
Day[3] = "星期三";
Day[4] = "星期四";
Day[5] = "星期五";
Day[6] = "星期六";
var timeValue = "";
timeValue += year+1900 + "年";
timeValue += ((month < 10) ? "0" : "") + month + "月";
timeValue += date + "日 ";
timeValue += (Day[day]) + " ";
timeValue += ((hours <= 12) ? hours : hours - 12);
timeValue += ((minutes < 10) ? ":0" : ":") + minutes;
timeValue += ((seconds < 10) ? ":0" : ":") + seconds;
timeValue += (hours < 12) ? "上午" : "下午";
//document.getElementById("face").innerText = timeValue;
document.getElementById("face").value = timeValue;
timerID = setTimeout("showtime()", 1000);
timerRunning = true
}
function startclock() {
stopclock();
showtime()
}
</script>

二.在body中在你对应的位置添加以下代码

<input  type="text" name="face" id="face" size="40" value=""  runat="server" style="border-color: #000080"/>

切记id,name要和js中的getElementById()对应!
