十、显示年月日星期及农历的月和日 如：2008年11月27日 星期四 农历 10月30日

第一步：将一下代码保存为.JS文件

XML/HTML代码

第二步：在你网页所需要的地方插入调用代码

XML/HTML代码
<script language=javascript src="刚才命名.js"></script>  

十一、根据不同的时候显示不同的问候+后面跟着一句不变的话 如：下午好! ……

XML/HTML代码
<SCRIPT language=javascript><!--   
     var welcomestring;   
     var mydate = new Date();   
     var myyear = mydate.getYear();   
     if(myyear < 300)myyear = 1900 + myyear ;   
     mymonth = mydate.getMonth()+1;   
     today = mydate.getDate();   
     myhour = mydate.getHours();   
     if(myhour<6)   
     welcomestring="凌晨好";   
     else if(myhour<9)   
     welcomestring="早上好";   
     else if(myhour<12)   
     welcomestring="上午好";   
     else if(myhour<14)   
     welcomestring="中午好";   
     else if(myhour<17)   
     welcomestring="下午好";   
     else if(myhour<19)   
     welcomestring="傍晚好";   
     else if(myhour<22)   
     welcomestring="晚上好";   
     else   
     welcomestring="夜里好";   
     document.writeln(welcomestring+ "!欢迎访问公安县夹竹园镇北湖渔场网站 ");   
     //-->  
     </SCRIPT>  

十二、显示年月日星期及今年的第几周 如：2008年11月27日 星期四 今年的第44周

XML/HTML代码
<script language=javascript>  
  function weekOfYear(year, month, day){   
  var date1 = new Date(year, 0, 1);   
  var date2 = new Date(year, month-1, day, 1);   
  var dayMS = 24*60*60*1000;   
  var firstDay = (7-date1.getDay())*dayMS;   
  var weekMS = 7*dayMS;   
  date1date1 = date1.getTime();   
  date2date2 = date2.getTime();   
  return Math.ceil((date2-date1-firstDay)/weekMS)+1;   
  }   
  
today=new Date();   
function initArray(){   
this.length=initArray.arguments.length;   
for(var i=0;i<this.length;i++)   
this[i+1]=initArray.arguments[i]   
}   
var d=new initArray("星期日","星期一","星期二","星期三","星期四","星期五","星期六");   
document.write("<font style='font-size:9pt;font-family: 宋体'>",today.getYear(),"年",today.getMonth()+1,"月",today.getDate(),"日 ",d[today.getDay()+1]," 今年的第",weekOfYear(today.getYear(),today.getMonth(),today.getDate()),"周","</font>");   
</script>
