Ajax update and submission using h:commandButton
提问by Wizard Sultan
How to update a div and do partial submission using <h:commandButton>, I have previously used <p:commandButton>to do partial submission by setting the ajax attribute to true and the update attribute to :statusBlock, where the id of the <h:panelGroup>is statusBlock. I am having some designing issues with <p:commandButton>so I cannot use it so I have to use <h:commandButton>.
如何更新div并使用 进行部分提交<h:commandButton>，我以前曾经<p:commandButton>通过将ajax属性设置为true并将更新属性设置为：statusBlock来进行部分提交，其中id<h:panelGroup>是statusBlock。我有一些设计问题，<p:commandButton>所以我无法使用它，所以我必须使用<h:commandButton>.

This is to be done by nesting a <f:ajax>in it.
这是通过<f:ajax>在其中嵌套 a 来完成的。
In effects,
在效果上，
<p:commandButton ... process="@form" update=":statusBlock" />
does exactly the same as
完全一样
<h:commandButton ...>
<f:ajax execute="@form" render=":statusBlock" />
</h:commandButton>
Note that the subtle difference with the PrimeFaces equivalent is that PrimeFaces defaults to @formin the process/execute, while the <f:ajax>one defaults to @this, so you might need to explicitly specify execute="@form"over all place where you didn't specify the processattribute in the PrimeFaces component.
请注意，与 PrimeFaces 等效项的细微差别在于 PrimeFaces@form在 process/execute 中<f:ajax>默认为@this，而默认为，因此您可能需要execute="@form"在所有未process在 PrimeFaces 组件中指定属性的地方显式指定。

You can just use the standard components alongside f:ajax e.g.
你可以在 f:ajax 旁边使用标准组件，例如
<h:form id="myForm">
<h:commandButton value="Push Me">
<f:ajax execute="myForm" render="statusBlock" />
</h:commandButton>
<h:panelGroup id="statusBlock">
</h:panelGroup>
</h:form>
