惯用jstl标签

1.数组:

${str[0]}.

如果为map也是在中括号里面写上key.即可取出值.

2.forEach

<core:forEach?items="${orgInfoAllList}"?var="orgInfoAllList"?varStatus="idx">

???? ?<core:if?test="${orgInfoAllList.orgId?==list.orgId}">${orgInfoAllList.orgName}</core:if>

</core:forEach>

3格式化时间:

<%@taglib?uri="http://java.sun.com/jsp/jstl/fmt"?prefix="fmt"?%>

<fmt:formatDate?pattern="yyyy-MM-dd?HH:mm:ss"?value="${list.logTime?}"/>

注意:①?mm?分,MM月

?????②?hh是12进制,HH是24小时进制.

4.格式化为2位小数位

<fmt:formatNumber?value="${list.amount?}"?pattern="0.00"/>

5.

取得list的size

${fn:length(resultList)

6.????判断是否为空和使用map取值

<c:if?test="${empty?list.accType}">

<select?id="accType"?name="accType">

<c:forEach?items="${bankMap}"?var="bankMap">

<option?value="${bankMap.key}">${bankMap.value}</option>

</c:forEach>

</select>

??</c:if>

<core:if?test="${empty?resultList}">

?</core:if> ???

7.choose,when

<c:choose>

?????? <c:when?test="${updateVo.status?==-1}">

</c:when>

?<c:otherwise>?

</c:otherwise>

?</c:choose>
