<c:if .的运用

首先加入?<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>

?

Jsp代码 ?

1. ?<c:if?test= "${queryType?==?'1'}" >??
2. ????<c:if?test="${?infoType?==?'0'}" >??
3. ????????<div?class="ttl_bar?ttl_16" >南京一日游</div>??
4. ????</c:if>??
5. ????<c:if?test="${?infoType?==?'1'}" >??
6. ????????<div?class="ttl_bar?ttl_16" >南京周边游</div>??
7. ????</c:if>??
8. ????<c:if?test="${?infoType?==?'2'}" >??
9. ????????<div?class="ttl_bar?ttl_16" >境内游</div>??
10. ????</c:if>??
11. ????<c:if?test="${?infoType?==?'3'}" >??
12. ????????<div?class="ttl_bar?ttl_16" >境外游</div>??
13. ????</c:if>??
14. ????<c:if?test="${?infoType?==?'4'}" >??
15. ????????<div?class="ttl_bar?ttl_16" >自驾游</div>??
16. ????</c:if>??
17. </c:if>??

?利用传入的queryType的值判断显示的内容

其中<c:if test=""></c:if>中test的内容的结果只能是布尔值

另外判断时候为空：<c:if test="${empty id}">、<c:if test="${!empty id}">
