分时段显示不同的提示的网页JS特效代码

 脚本说明:
 把如下代码加入body区域中
 <SCRIPT>
 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';
 else if(hour<3)wel='丑时';
 else if(hour<5)wel='寅时';
 else if(hour<7)wel='卯时';
 else if(hour<9)wel='辰时';
 else if(hour<11)wel='巳时';
 else if(hour<13)wel='午时';
 else if(hour<15)wel='未时';
 else if(hour<17)wel='申时';
 else if(hour<19)wel='酉时';
 else if(hour<21)wel='戌时';
 else if(hour<23)wel='亥时';
 else {wel='子时';}
 document.write(hello);
 </SCRIPT>！ 现在是<SCRIPT>
 document.write(date + ' ' + day + ' ' + wel);
     </SCRIPT>
