推荐答案
如果你至少使用 PrimeFaces 3.3,那么你可以使用 PrimeFaces 选择器.这允许您在 process
和 中使用 jQuery CSS 选择器语法>更新
PrimeFaces ajax 组件的属性.
If you're using at least PrimeFaces 3.3, then you can use PrimeFaces Selectors for this. This allows you using jQuery CSS selector syntax in process
and update
attributes of PrimeFaces ajax components.
例如:
<h:form>
<h:inputText ... />
<h:inputText ... />
<h:inputText ... styleClass="noupdate" />
<h:inputText ... />
<h:inputText ... />
<p:commandButton ... update="@(form :not(.noupdate))"/>
</h:form>
此示例将更新整个表单,除了客户端中具有 class="noupdate"
的输入.
This example will update the entire form except for inputs having class="noupdate"
in the client side.
如果你想更新某个组件的所有子组件,除了一个组件,用周围组件(或类或...)的 id 替换 'form'
If you want to update a all children of a certain component except one, replace 'form' by the id of the surrounding component (or a class or...)
<h:form id="form">
<h:panel id="myPanel">
<h:inputText ... />
<h:inputText ... />
<h:inputText ... styleClass="noupdate" />
</h:panel>
<h:inputText ... />
<h:inputText ... />
<p:commandButton ... update="@(form :not(.noupdate))"/>
</h:form>
<p:commandButton ... update="@(#form:myPanel :not(.noupdate))"/>
只需确保使用完整的客户端 ID.
Just make sure you use the full client-side id.
