寻找一个带星期的时间,日期显示代码

<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;
  date1 = date1.getTime();
  date2 = 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]," 第",weekOfYear(today.getYear(),today.getMonth(),today.getDate()),"周","</font>");
