struts2 iterator嵌套的问题

Question

一个iterator对应一个list
你把他们区分开来试试，就是再定义个list
不要2个引用同一个

Answer 1

可以这样 <s:iterator value="categorys" id="xxx">
                <s:property value='name'/> -- <s:property value='id'/>"
        
                <s:iterator value="#xxx.products">
                    (<s:property value="name"/> -- <s:property value="id"/>
                </s:iterator>
            
            </s:iterator>

Answer 2

建议采用树或者doubleselect标签

Answer 3

 <s:iterator value="categorys" id="xxx">
                <s:property value='name'/> -- <s:property value='id'/>"
        
                <s:iterator value="#xxx.products">
                    (<s:property value="name"/> -- <s:property value="id"/>
                </s:iterator>
            
            </s:iterator>
不错
