I'm working with jsf2 and want to use the ajax-functionality of it. Problem: I've already seen some ajax refresh things. But nothing to refresh a whole div...

我有一个xhtml页面，其中包含来自我的bean的数据，我真的不想刷新它的所有字段，刷新整个ui:include ...

有人知道解决方案吗?还是我必须手动刷新所有字段?

does anybody knows a solution? Or do I have to refresh all fields manually?

推荐答案

只需将它们放入具有ID的某个容器组件中，并在f:ajax的render属性中使用它即可.

Just put them in some container component with an ID and use it in render attribute of f:ajax.

<h:form>
    <h:commandButton value="submit" action="#{bean.submit}">
        <f:ajax render=":foo" />
    </h:commandButton>
</h:form>
<h:panelGroup id="foo" layout="block">
    <ui:include src="include.xhtml" />
</h:panelGroup>

请注意，<h:panelGroup layout="block">呈现<div>.如果省略layout属性，则默认为<span>(仅当有任何需要呈现为HTML的属性(例如id)时).

Note that <h:panelGroup layout="block"> renders a <div>. If you omit the layout attribute, it defaults to <span> (only whenever there are any attributes which needs to be rendered to HTML, like id).
