s:iterator巧妙控制跳出循环

<s:set name="index" value="1" />  
<s:iterator value="#detail.members" var="memeber" id="memeber" status="status">  
    <s:if test=‘%{#memeber.attr1 == "admin" }‘>  
        <s:if test="#index==1">  
            <s:set name="index" value="2" />  
            <s:property value="#memeber.nickName"/>  
        </s:if>  
    </s:if>  
</s:iterator>
