如何使用 Struts 2 标签迭代 Set 元素
我有两个Sets
set1 contains("A","B","C","D") elements
set2 contains("E","F","D","G") elements
我想将 set1 的每个元素与 set2 的每个元素进行比较，并使用 Struts2 标签显示匹配的元素.
I want to compare every element of set1 with every element of set2 and display matched elements using Struts2 tags.
推荐答案
试试下面的代码:
<s:iterator var="val1" value="set1">
<s:iterator var="val2" value="set2">
<s:if test="#val1 == #val2">
<s:property /><br>
</s:if>
</s:iterator>
</s:iterator>
