假设在页面中一个ID=‘clock’的div里面作显示，以下是代码,在页面开始的时候掉一下这个方法：
function clock(){
var d = new Date();
document.getElementById('clock').innerHTML = d.getFullYear()+"年"+(d.getMonth()+1)+"月"+d.getDate()+"日 "+d.getHours()+":"+d.getMinutes()+":"+d.getSeconds();
setTimeout("clock()",1000);
}
function clock(){
var d = new Date();
document.getElementById('clock').innerHTML = d.getFullYear()+"年"+(d.getMonth()+1)+"月"+d.getDate()+"日 "+d.getHours()+":"+d.getMinutes()+":"+d.getSeconds();
setTimeout("clock()",1000);
}

在你的网页里面放一个ID=time 的Div ，在head里面引用下Jquery，然后把下面的函数加入Head标签里面就可以用了
$(document.ready(){
setTimeInfo();
});
function setTimeInfo() {
setInterval(new function () {
$('#time').html("");
day = new Date();
ym = day.toLocaleDateString();
hr = day.getHours();
minu = day.getMinutes();
sec = day.getSeconds();
s = "您好，现在是：" + ym + " ";
s = s + hr + "点" /*+ minu + "分" + sec*/ + ' 星期' + '日一二三四五六'.charAt(day.getDay()) + " ";
$('#time').html(s);
}, 10000);
}
$(document.ready(){
setTimeInfo();
});
function setTimeInfo() {
setInterval(new function () {
$('#time').html("");
day = new Date();
ym = day.toLocaleDateString();
hr = day.getHours();
minu = day.getMinutes();
sec = day.getSeconds();
s = "您好，现在是：" + ym + " ";
s = s + hr + "点" /*+ minu + "分" + sec*/ + ' 星期' + '日一二三四五六'.charAt(day.getDay()) + " ";
$('#time').html(s);
}, 10000);
}

<!-- #BeginDate format:Ch2 -->2012年4月22日 <!-- #EndDate -->

或者
<script language="JavaScript">
var enabled = 0; today = new Date();
var day; 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 = "000000";
date = "今天是" + (today.getYear()) + "年" + (today.getMonth() + 1 ) + "月" + today.getDate() + "日" + day +"";
document.write(date);
</script>
