jstl when otherwise 多重判断问题

Question

问一下,JSTL标签里的多重判断问题
下面的语句可不可以? 即能不能嵌套判断?<c:choose>
     <c:when test=""></c:when>
 
     <c:otherwise>
            <c:when test=""></c:when>    <!--这里能不能加入这个判断?-->
           
            <c:otherwise></c:otherwise>
     </c:otherwise>
  <c:choose>

Answer 1

知道了
应加个<c:choose></c:choose><c:choose>
     <c:when test=""></c:when>
     
     <c:otherwise>
          <c:choose>
            <c:when test=""></c:when>              
            <c:otherwise></c:otherwise>
         <c:choose>
     </c:otherwise>
  <c:choose>

Answer 2

应该是这样：lz的<c:choose>掉了两个"/"  <c:choose>
     <c:when test=""></c:when>
     <c:otherwise>
          <c:choose>
            <c:when test=""></c:when>              
            <c:otherwise></c:otherwise>
         </c:choose>
     </c:otherwise>
  </c:choose>

Answer 3

再问一个问题<c:if>能不能嵌套?
即能不能下面这样?  <c:if>
       <c:if></c:if>
       <c:if></c:if>
       <c:if></c:if>
  </c:if>

Answer 4

<c:if>也可以。<c:if test="${param.aaa=='ok'}">
       okaaa
       <c:if test="${param.bbb=='ok'}">
           okbbb
        <c:if test="${param.ccc=='ok'}">
        okccc
        </c:if>
      </c:if>
</c:if>
