JSP中使用JSTL按不同条件输出内容的方法

 <%@ page language="java" contentType="text/html;charset=UTF-8" %><%@ taglib uri="/WEB-INF/tld/c-rt.tld" prefix="c-rt" %>   <%-- if condition --%> This is printed if parameter "myparam1" equals "myvalue1" 
<%-- if/else condition --%>  This is printed if parameter "myparam2" equals "myvalue2" 
 This is printed if parameter "myparam2" DOES NOT equal "myvalue2" 
<%-- multiple conditions --%>  This is printed if parameter "myparam1" equals 0 
 This is printed if parameter "myparam1" equals 1 
 This is printed for any other value of the parameter
