一个简单的JS显示日期代码，只有日期和星期，需要的话也可以把星期也屏了。
<script type="text/javascript">
function showweek() //显示中文星期
{
now = new Date() //定义新对象，new具有Date的性质
if (now.getDay() == 0) return ("星期日")
if (now.getDay() == 1) return ("星期一")
if (now.getDay() == 2) return ("星期二")
if (now.getDay() == 3) return ("星期三")
if (now.getDay() == 4) return ("星期四")
if (now.getDay() == 5) return ("星期五")
if (now.getDay() == 6) return ("星期六")
}
function showdate() //显示系统日期
{
var now=new Date();
var year = now.getYear();
var month = now.getMonth()+1;
var day = now.getDate();
return year+"年"+month+"月"+day+"日";
}
</script>
显示：<script language="javascript">document.write("今天是："+showdate()+" "+showweek())</script>
