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。
