网站头部动态日期--JS实现

<script language='javascript'>


today=new Date();


var day; var date; var hello; var wel;




hour=new Date().getHours()




if(hour < 6)hello='凌晨好'


else if(hour < 9)hello='早上好！'


else if(hour < 12)hello='上午好！'


else if(hour < 14)hello='中午好！'


else if(hour < 17)hello='下午好！'


else if(hour < 19)hello='傍晚好！'


else if(hour < 22)hello='晚上好！'




else ...{hello='夜里好!'}




if(today.getDay()==0)day='星期日'


else if(today.getDay()==1)day='星期一'


else if(today.getDay()==2)day='星期二'


else if(today.getDay()==3)day='星期三'


else if(today.getDay()==4)day='星期四'


else if(today.getDay()==5)day='星期五'


else if(today.getDay()==6)day='星期六'




date=(today.getYear())+'年'+(today.getMonth() + 1 )+'月'+today.getDate()+'日';




if(hour<1)wel='子时';

</script>

测试效果：<table border="0" width="120" cellspacing="0" cellpadding="0">
<tr height="19" align="center">
<td>
<script>document.write("大家，"+hello);</script>
</td>
</tr>

<tr height="19" align="center">
<td style="border-bottom:#000000 solid 1px;padding:0 0 2 0;">
<SCRIPT>document.write(date+day)</SCRIPT>
</td>
</tr>
<tr height="19" align="center">
<td style="padding:0 0 4 0;">www.lrn.cn</td>
</tr>
</table>

把JS代码与测试代码写到同一个HTML页面中运行。
