本文实例讲述了JSP中使用JSTL按不同条件输出内容的方法。分享给大家供大家参考。具体如下:

ConditionalContentJSTL.jsp页面:

<%@ page language="java" contentType="text/html;charset=UTF-8" %><%@ taglib uri="/WEB-INF/tld/c-rt.tld" prefix="c-rt" %><html><head> <title>Java Code Geeks Snippets - Conditional Content with JSTL in JSP Page</title></head><body> <%-- if condition --%> <c-rt:if test='${param.myparam1 == "myvalue1"}'>  This is printed if parameter "myparam1" equals "myvalue1" </br> </c-rt:if> <%-- if/else condition --%> <c-rt:choose>  <c-rt:when test='${param.myparam2 == "myvalue2"}'>   This is printed if parameter "myparam2" equals "myvalue2" </br>  </c-rt:when>  <c-rt:otherwise>   This is printed if parameter "myparam2" DOES NOT equal "myvalue2" </br>  </c-rt:otherwise> </c-rt:choose> <%-- multiple conditions --%> <c-rt:choose>  <c-rt:when test='${param.myparam3 == "0"}'>   This is printed if parameter "myparam1" equals 0 </br>  </c-rt:when>  <c-rt:when test='${param.myparam3 == "1"}'>   This is printed if parameter "myparam1" equals 1 </br>  </c-rt:when>  <c-rt:otherwise>   This is printed for any other value of the parameter </br>  </c-rt:otherwise> </c-rt:choose></body>

希望本文所述对大家的JSP程序设计有所帮助。
