樓主用了比較質樸的方式實現：easyUI-combobox下拉框。暫時還沒有能力寫成控制元件的形式。

在寫程式碼之前自己寫一個手動格式化時間的方法，為我們的程式碼做鋪墊：

Date.prototype.Format = function(fmt)  
	{  
	  var o = { 
	    "M+" : this.getMonth()+1,                 //月份 
	    "d+" : this.getDate(),                    //日 
	    "h+" : this.getHours(),                   //小時 
	    "m+" : this.getMinutes(),                 //分 
	    "s+" : this.getSeconds(),                 //秒 
	    "q+" : Math.floor((this.getMonth()+3)/3), //季度 
	    "S"  : this.getMilliseconds()             //毫秒 
	  }; 
	  if(/(y+)/.test(fmt)) 
	    fmt=fmt.replace(RegExp.$1, (this.getFullYear()+"").substr(4 - RegExp.$1.length)); 
	  for(var k in o) 
	    if(new RegExp("("+ k +")").test(fmt)) 
	  fmt = fmt.replace(RegExp.$1, (RegExp.$1.length==1) ? (o[k]) : (("00"+ o[k]).substr((""+ o[k]).length))); 
	  return fmt; 
	}
 

</pre><pre name="code" class="html">function initWeek(year,id){
	var currentYear = year;
	var thisyearbeginday = new Date(currentYear,0,1);
	var thisyearendday  = new Date(currentYear,11,31);
	var thisWeekBegin = new Date();
	var thisWeekEnd = new Date();
	if(thisyearbeginday.getDay() == 0){
		
		thisyearbeginday.setDate(thisyearbeginday.getDate()+1);
		
	}else if(thisyearbeginday.getDay() != 1){
		
		thisyearbeginday.setDate(thisyearbeginday.getDate() + 8 - thisyearbeginday.getDay());
	}
	
	thisWeekBegin = thisyearbeginday;
	
	if(thisyearendday.getDay() != 0){
	
		thisyearendday.setDate(thisyearendday.getDate() + 7 - thisyearendday.getDay());
	}
	thisWeekEnd = thisyearendday;	
	//alert(thisWeekBegin.getDate()+"年頭周");
	//alert(thisWeekEnd.getDate()+"年尾周"); 
	var week1Obj = $("#"+id);
	var weekHtml = "";
	var myweek = 1;
	var nowweekValue = 0;
	//迴圈迭代出所需的週數
	var json = [];
	while(thisWeekBegin.getTime() <= thisWeekEnd.getTime()){
		var beginTimes = thisWeekBegin.getTime();
		var begin = thisWeekBegin.Format("yyyy-MM-dd");
		thisWeekBegin.setDate(thisWeekBegin.getDate()+6);
		var end = thisWeekBegin.Format("yyyy-MM-dd");
		var todayTimes = new Date().getTime();
		
		thisWeekBegin.setDate(thisWeekBegin.getDate()+1);
		var endTimes = thisWeekBegin.getTime();
		if(todayTimes>=beginTimes&&todayTimes<=endTimes){
			nowweekValue = myweek;
		}
		json.push({"id":myweek,"text":myweek+"("+begin+"~"+end+")"});
		myweek++;
	}
	$("#"+id).combobox({
		valueField: 'id',
		textField: 'text',
		value:"",
		height: 30,
		width:190,
		panelHeight: json.length >= 7 ? "135px" : "auto"}).combobox("loadData", json);
	if(nowweekValue >= 2){
		$("#"+id).combobox("setValue",nowweekValue-1);
	}
}	
 

在jsp中程式碼：

<select id="weeknum"></select>
