Primefaces选择器:更新最接近的表单时如何排除某些组件?

问题描述

我正在使用PrimeFaces commandButton发出Ajax请求.
我应该设置update属性，以便除了某些特定组件以外，可以更新整个父窗体(假设我已经用styleClass="noupdate"标记了它们).
我正在使用PrimeFaces 3.5，所以我认为PrimeFaces jQuery选择器可能会有所帮助.
我尝试过这样的事情:

I'm using a PrimeFaces commandButton to issue an Ajax request.
I should set the update attribute so that the whole parent form be updated EXCEPT for some specific components (Let's say I've tagged them with styleClass="noupdate").
I'm using PrimeFaces 3.5, so I think PrimeFaces JQuery Selectors may help.
I tried something like this:

<!-- ...some inputs/labels to be updated here... -->
<p:overlayPanel styleClass="noupdate">
    <!-- ...some inputs/labels to be updated here... -->
    <p:commandButton id="btnDoIt" value="Do it" 
            update="@(this.closest('form') :not(.noupdate))"/>  
</p:overlayPanel>

但是它不起作用(我收到一个JavaScript语法错误).
有什么方法可以得到我需要的东西吗?
请注意:
1)表单ID未知，因为该按钮是复合组件的一部分，该组件可以由不同视图中的任何表单托管.
2)在我的示例中，必须不更新<p:overlayPanel>本身，但是必须更新任何后代组件.
3)视图中有多种形式，我应该只处理当前"形式.

but it doesn't work (I get a JavaScript Syntax Error).
Is there a way to get what I need?
Notice that:
1) The form id is not known because the button is part of a composite component that can be hosted by any form in different views
2) In my example the <p:overlayPanel> itself must not be updated, but any descendant component do.
3) There are more than one form in the view, and I should work on the "current" one only.

在此先感谢您能帮助我.

Thank you in advance to anyone can help me.

推荐答案

在this这样的东西="nofollow noreferrer"> PrimeFaces选择器. PrimeFaces选择器中绝对没有像$.closest()这样的jQuery函数.它只能是纯与jQuery兼容的CSS选择器，而不是一些JavaScript代码. /p>

There's no such thing as this in PrimeFaces selectors. There are definitely no jQuery functions like $.closest() available in PrimeFaces selectors. It has just to be a pure jQuery-compatible CSS selector, not some JavaScript code.

<p:commandButton ... update="@(form :not(.noupdate))"/>
