推荐答案

<p:dialog> 支持 ajax close 事件.这只需要将它放在 <h:form> 内(与 一般建议相反)，因此您需要确保它已经手动定位到 <h:body> 的最后，并且您没有使用 appendToBody.

The <p:dialog> supports the ajax close event. This only requires it being placed inside a <h:form> (on contrary to the general recommendation), so you need to make sure that it's already manually poisitioned to the very end of the <h:body> and that you don't make use of appendToBody.

<h:body>
    <h:panelGroup id="content" layout="block">
        ...
    </h:panelGroup>

    ...

    <h:form>
        <p:dialog>
            <p:ajax event="close" update=":content" />
            ...
        </p:dialog>
    </h:form>
</h:body>

如果您打算更新整个页面，请在必要时使用update="@all".但更好的是只更新真正需要更新的部分.

Use if necessary update="@all" if you intend to update the entire page. But better is to update only the parts which really need to be updated.
