JSP的c:set來進行累計

記錄項目中關於c標籤的c:when,c:forEach,c:set的處理

c:choose和c:when條件判斷

<c:choose><c:when test="${!(empty dataList) && (fn:length(dataList))> 0 }">

 c:forEach遍歷

<c:forEach items="${dataList}" var="obj" varStatus="index">

c:set來進行累計

<c:set var="lastMonthPersonTotal" value="${lastMonthPersonTotal + daily.personNumberLastMonth }"></c:set> 

整段代碼如下：

<c:choose><c:when test="${!(empty dataList) && (fn:length(dataList))> 0 }">
			<c:forEach items="${dataList}" var="obj" varStatus="index">			
	 			<c:choose>
	 				<c:when test="${!(empty obj.departmentCapacityDailyModelList) && (fn:length(obj.departmentCapacityDailyModelList))> 0 }">
	 				<c:forEach items="${obj.departmentCapacityDailyModelList}" var="daily" varStatus="index1">  
                        <c:set var="lastMonthPersonTotal" value="${lastMonthPersonTotal + daily.personNumberLastMonth }"></c:set> 
                        <c:set var="thisQuarterPersonTotal" value="${thisQuarterPersonTotal + daily.personNumberThisQuarter }"></c:set> 
                        <c:set var="historyReturnWorkPersonTotal" value="${historyReturnWorkPersonTotal + daily.personTotalNumberRework }"></c:set>   
                        <c:set var="todayReturnWorkPersonTotal" value="${todayReturnWorkPersonTotal + daily.personTodayNumberRework }"></c:set>   
                        <c:set var="todayWorkPersonTotal" value="${todayWorkPersonTotal + daily.personTotalNumberWork }"></c:set>
