我查看了此站点上以前的示例，但无法正常工作。我也用谷歌搜索了我的困境，但没有成功。

我正在尝试在这里调试一些代码。我似乎可以去掉最后一个逗号。想法？

<c:forEach items="${userDeptList}" var="userDeptVar" varStatus="userDeptCounter" >
   <c:if test="${contactsVar.userId==userDeptVar.userID}">
      <c:forEach items="${deptPtypeList}" var="deptsVar" varStatus="deptsCounter" > 
         <c:if test="${deptsVar.ptypeID==userDeptVar.deptID}">
            <c:out value="${deptsVar.type}" escapeXml="false"></c:out>
            <c:out value="," escapeXml="false"></c:out> 
         </c:if>    
      </c:forEach>                          
   </c:if>                  
</c:forEach>

要省略最后的逗号，您可以以这种方式测试您是否在最后一项

<c:forEach items="${userDeptList}" var="userDeptVar" varStatus="userDeptCounter" >
   <c:if test="${contactsVar.userId==userDeptVar.userID}">
      <c:forEach items="${deptPtypeList}" var="deptsVar" varStatus="deptsCounter" > 
         <c:if test="${deptsVar.ptypeID==userDeptVar.deptID}">
            <c:out value="${deptsVar.type}" escapeXml="false"></c:out>
            <c:if test="${not userDeptCounter.last}>
              <c:out value="," escapeXml="false"></c:out> 
            </c:if>
         </c:if>    
      </c:forEach>                          
   </c:if>                  
</c:forEach>

这里是所有varStatus属性的列表

current    The item (from the collection) for the current round of iteration
index      The zero-based index for the current round of iteration
count      The one-based count for the current round of iteration
first      Flag indicating whether the current round is the first pass through the iteration
last       Flag indicating whether the current round is the last pass through the iteration
begin      The value of the begin attribute
end        The value of the end attribute
step       The value of the step attribute

利用varStatus

<c:if test="${not deptsCounter.last}">
</c:if>
