經過選擇時間獲取當前時間屬於本年的第幾周的方法以及其餘幾種時間控件

1.時間轉爲本週第幾周的問題，首先jsp

<input readonly class="easyui-textbox Wdate" type="text" id="weekFmt1" name="weekFmt1" value=""onclick="WdatePicker({isShowWeek:true,el:'chooseDate1',dateFmt:'yyyy-MM-dd',oncleared:funclean1,onpicked:funccc1})" style="width:60%;"/>

 

而後js:經過之後js就能將選擇的時間轉爲當年的第幾周

//週日期選擇
function funccc1(){
	var year = $dp.cal.getP('y');
	if($dp.cal.getP('M')==12 && $dp.cal.getP('W')==1){//若選擇的日期是月份12可是返回的周爲1
		year = parseInt(year)+1;
	}
	if($dp.cal.getP('M')==1 && $dp.cal.getP('W')>50){//若選擇的日期是月份1可是返回的周很大
		year = parseInt(year)-1;
	}
	var week = $dp.cal.getP('W','WW');
	var weekFmt = year+"年"+$dp.cal.getP('W','WW')+"周";
	$("#weekFmt1").val(weekFmt);
	$.ajax({
        cache: true,
        type: "POST",
        url:'weekplantask_formateWeek.do',
        data:{year:year,week:week},
        async: false,
        success: function(result) {
        	 if (result.StartDayOfWeekNo == undefined) {
	  				result = eval('(' + result + ')');
	  			}
        	 var StartDayOfWeekNo=result.StartDayOfWeekNo;
        	 var EndDayOfWeekNo=result.EndDayOfWeekNo;
        	$('#showbegdate1').text(StartDayOfWeekNo);
        	$('#showbegdate2').text('至'+EndDayOfWeekNo);
        }
	});
}
//週日期清除
function funclean1(){
	$("#week1").val("");
	$("#weekFmt1").val("");
	return;
}

3.若是須要本週星期一的開始日期  以及本週的結束日期，經過ajax去後臺處理，附上代碼：

首先經過週期獲取年周

    String year1=request.getParameter("year");
            String week1=request.getParameter("week");
            int year=Integer.valueOf(year1);
            int week=Integer.valueOf(week1);

而後經過工具類獲取每一天的日期：eg:2015年12周

import java.util.Calendar;




public class WeekUtils {

        
      /*  public static void main(String[] args) {  
              
            WeekUtils cd = new WeekUtils();  
            System.out.println("開始時間: " + cd.getStartDayOfWeekNo(2017,9) );  
            System.out.println("結束時間:" + cd.getEndDayOfWeekNo(2017,9) );      
              
        }*/

第一張的日期做法如上！

2.

<input id="benDate" name="benDate"  class="Wdate" 
					style="height:32px;  width: 140px;  cursor: hand; vertical-align: middle;margin-left:0px;"
					onclick="WdatePicker({dateFmt:'yyyy-MM-dd',minDate:'%y-%M-%d',maxDate:'#F{$dp.$D(\'endDate\')}'})" />
					~				 
	              <td class="td_t" align="left">
	              	<input id="endDate" name="endDate"  class="Wdate"
					style="height:32px;width:140px; cursor: hand; vertical-align: middle;margin-left:0px;"
					onclick="WdatePicker({dateFmt:'yyyy-MM-dd',minDate:'#F{$dp.$D(\'benDate\')}'})" />
	              </td>   



$(function(){
	//初始化開始和結束日期
	$('#benDate').val(_getCurDate());
	$('#endDate').val(_getCurDate());}

三、月份

<input id="taskMonth" name="taskMonth" readonly
								class="Wdate" style="width: 140px; cursor: hand; vertical-align: middle;"
								onclick="WdatePicker({dateFmt:'yyyy-MM'})" />
