现在应该很少人去写JS了，一般用的都是别人的，当然这也是一个惯例，毕竟现在写JS太费时间了，况且自己写的JS还不一定是很好，今天TC写个时间的JS都纠结了半天，还是的去网上找，好了，技术文章不口水太多给大家上案例：

当前时间日期函数为：
Date();

那么我们把当前时间赋值给一个变形now,然后下面方便调用即：

now=Date();
年：
 now.getFullYear();
月：
 now.getMonth()+1;
日：
 now.getUTCDate();
时：
 now.getHours();
分：
 now.getMinutes();
秒：
 now.getSeconds();
星期（星期的结果是数字，星期日值为0）：
 now.getDay();

当然星期的脚本也就出来了。

var weekday=new Array(7)
weekday[0]="日"
weekday[1]="一"
weekday[2]="二"
weekday[3]="三"
weekday[4]="四"
weekday[5]="五"
weekday[6]="六"
weekday[now.getDay()]

我们用一个完整的例子来看下效果。

<script> 
now=new Date(); 
document.write("现在时间："+now+"<BR>");
nyear=now.getFullYear();
document.write("年："+nyear+"<BR>");
nmonth=now.getMonth()+1;
document.write("月："+nmonth+"<BR>");
nday=now.getUTCDate();
document.write("日："+nday+"<BR>");
var weekday=new Array(7)
weekday[0]="日"
weekday[1]="一"
weekday[2]="二"
weekday[3]="三"
weekday[4]="四"
weekday[5]="五"
weekday[6]="六"
nwday=weekday[now.getDay()];
document.write("星期："+nwday+"<BR>");
nhrs=now.getHours();
document.write("时："+nhrs+"<BR>");
nmin=now.getMinutes();
document.write("分："+nmin+"<BR>");
nsec=now.getSeconds();
document.write("秒："+nsec+"<BR>");
document.write("现在时间："+nyear+"年"+nmonth+"月"+nday+"日星期"+nwday+nhrs+"时"+nmin+"分"+nsec+"秒"+"<BR>");
</script>

网上还有农历的调用方法也给大家展示一下。

<script>
t0=new Date().getTime();
now=new Date();
nhrs=now.getHours();
nmin=now.getMinutes();
nsec=now.getSeconds();
nyear=now.getFullYear();
nmonth=now.getMonth()+1;
nday=now.getUTCDate();
nwday=now.getUTCDay();

function NewTick(){noww=new Date();t1=noww.getTime();
tnext=last0+200;
if(t1<tnext){t1=tnext;}
else if((t1-tnext)>45000&last0!=t0){t1=tnext;}
last0=t1;
noww.setTime(t1+dectime);
if(noww.getDate()!=nday){
nextday=true;
nyear=noww.getFullYear();
nmonth=noww.getMonth()+1;
nwday=noww.getDay();
nday=noww.getDate();
getlday();}
nhrs=noww.getHours();nmin=noww.getMinutes();nsec=noww.getSeconds();
}
dectime=new Date(nyear,nmonth-1,nday,nhrs,nmin,nsec).getTime()-t0;
