老师我用setAttribute传一个数组过去，为什么无法输出

<q:forEach items="arr" var="arr[i]">

<q:if test="${arr[i]%4==0&&arr[i]%5==0 }">

<q:out value="${arr[i] }"></q:out>

</q:if>

</q:forEach>

代码改成如下形式：

<q:forEach items="${arr}" var="arr1">

<q:if test="${arr1%4==0&&arr1%5==0}">

<q:out value="${arr1}"></q:out>

</q:if>

</q:forEach>

祝学习愉快！
