使用h:commandButton更新和提交Ajax [英] Ajax update and submission using h:commandButton

问题描述

如何使用<h:commandButton>更新div并进行部分提交，我以前使用<p:commandButton>通过将ajax属性设置为true并将update属性设置为:statusBlock来进行部分提交，其中是statusBlock.我在<p:commandButton>上遇到一些设计问题，所以我无法使用它，所以必须使用<h:commandButton>.

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>.

推荐答案

这是通过嵌套

This is to be done by nesting a <f:ajax> in it.

实际上，

<p:commandButton ... process="@form" update=":statusBlock" />

与

<h:commandButton ...>
    <f:ajax execute="@form" render=":statusBlock" />
</h:commandButton>

请注意，与PrimeFaces等效项的细微差别在于，PrimeFaces在进程/执行中默认为@form，而<f:ajax>一个默认为@this，因此您可能需要在所有字段中明确指定execute="@form"没有在PrimeFaces组件中指定process属性的地方.

Note that the subtle difference with the PrimeFaces equivalent is that PrimeFaces defaults to @form in 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 process attribute in the PrimeFaces component.
