把下面全部代码放到期中就可以获取当前日期+星期

<script>

function writeDateInfo()
{
var day="";
var month="";
var ampm="";
var ampmhour="";
var myweekday="";
var year="";
mydate=new Date();
myweekday=mydate.getDay();
mymonth=mydate.getMonth()+1;
myday= mydate.getDate();
myyear= mydate.getYear();
year=(myyear > 200) ? myyear : 1900 + myyear;
if(myweekday == 0)
weekday=" 星期日";
else if(myweekday == 1)
weekday=" 星期一";
else if(myweekday == 2)
weekday=" 星期二";
else if(myweekday == 3)
weekday=" 星期三";
else if(myweekday == 4)
weekday=" 星期四";
else if(myweekday == 5)
weekday=" 星期五";
else if(myweekday == 6)
weekday=" 星期六";
document.write(year+"年"+mymonth+"月"+myday+"日"+weekday);
}

</script>

<script>writeDateInfo();</script>
