JSTL 的 if else : 有 c:if 没有 else 的处理

分类: JSP/JAVA/J2EE(11) 作者同类文章X   jstl的c:if 没有else   想要实现if...else...:     可以用下面的解决    --------------------------------------------------------------------    结构:     <c:choose>    <c:when test="">    如果    </c:when>        <c:otherwise>  否则    </c:otherwise>     </c:choose>       代码:    <c:choose>       <c:when test="${sessionScope.USERTYPE == 'inner'}">         <c:set value="${context_root}/igmgr/MEB004.dow" var="action" scope="page"/>       </c:when>       <c:when test="${sessionScope.USERTYPE == 'merc'}">         <c:set value="${context_root}/igmgr/MEB021.dow" var="action" scope="page"/>       </c:when>        <c:otherwise>           <c:set value="${context_root}/igmgr/MEB020.dow" var="action" scope="page"/>      </c:otherwise>     </c:choose>    -------------------------------------------------------------------------    附:详解+代码    在同一个 <c:choose> 中,当所有 <c:when> 的条件都没有成立时,则执行 <c:otherwise> 的本体内容。     语法     <c:otherwise>     本体内容     </c:otherwise>     属性     无     限制     ·<c:otherwise> 必须在 <c:choose> 和 </c:choose>之间     ·在同一个 <c:choose> 中时,<c:otherwise> 必须为最后一个标签     说明     在同一个 <c:choose> 中,假若所有 <c:when> 的test属性都不为true时,则执行 <c:otherwise> 的本体内容。     范例     笔者举一个典型的 <c:choose>、<c:when>和<c:otherwise>范例:     <c:choose>     <c:when test="${condition1}">     condition1为true     </c:when>     <c:when test="${ condition2}">     condition2为true     </c:when>     <c:otherwise>     condition1和condition2都为false     </c:otherwise>     </c:choose>     范例说明:当condition1为true时,会显示“condition1为true”;当condition1为false且condition2为true时,会显示“condition2为true”,如果两者都为false,则会显示“condition1和condition2都为false”。     注意     假若condition1和condition2两者都为true时,此时只会显示"condition1为true",这是因为在同一个<c:choose>下,当有好几个<c:when>都符合条件时,只能有一个<c:when>成立     FOR                                                                                            <c:forEach items="${SurveyDirectorys }" var="en" varStatus="i">                                                                                     <c:set var="isDoing" value="0"/>                                                                                                 <c:forEach items="${roles }" var="v" varStatus="i">                                                                                                       <%-- <input type="checkbox" name="sd_${en.id}" value="${en.id}" checked="1" >${en.surveyName} --%>                                                                                                       <c:choose>                                                                                                       <c:when test="${v.ruleId eq en.id }">                                                                                                                                                                                                                                                                                                                       <input type="checkbox" name="export_role" value="${role.id}" checked="1" >${en.surveyName}                                                                                                             </c:when>                                                                                                       <c:otherwise>                                                                                                                                                                                                                     <input type="checkbox" name="export_role" value="${role.id}"  >${en.surveyName}                                                                                                             </c:otherwise>                                                                                                       </c:choose>                                                                                                 </c:forEach>                                                                                           </c:forEach>
