Struts2 dojo Anchor tag does not work?

问题

Tag <sx:head /> is present on the page. I try to update content of div:

<div id="div1">
...
</div>

<s:url id="ajaxData" value="/ajaxData.action" />
<sx:a id="link1" href="%{ajaxData}" targets="div1">
update data
</sx:a>

action

public String execute() {
    ...
    return NONE;
}

xml

<action name="ajaxData" class="com.data.action.AjaxDataAction">
    <result name="none">/page.jsp</result>
</action>

But when I press update data the browser tab shows animation, it means that whole page updates? It reloads the whole page, not only div, I want to reload only div partially.
