如果您能帮我解决这个问题，我将不胜感激.

I am trying to iterate over two 2D arrays Org_Positions_IdTitle and Org_Apps and print out a field but I keep getting the Attribute var invalid for tag iterator according to TLD also in my jsp page the var1 and var2 are underlined and it says on the left Undefined attribute name "var".

        <s:iterator value="Org_Apps" var="arr2" >
            <s:if test="#arr1[0] == #arr2[1] ">
                <s:property value="#arr1[1]" />     
            </s:if>
        </s:iterator>
    </s:iterator> 

推荐答案

您使用哪个版本的 Struts 2?

Which version of Struts 2 do you use?

如果您的版本低于 2.1.x，您应该使用 id 属性，根据文档:http://struts.apache.org/release/2.1.x/docs/iterator.html

If your version less then 2.1.x you should use id attribute, according to documentation: http://struts.apache.org/release/2.1.x/docs/iterator.html
