单击CommandLink即可关闭Primefaces lightBox [英] Primefaces lightBox closes at click on commandLink

问题描述

这只是一个简单的Primefaces灯箱，我想在其中使用commandLinks.不幸的是，当我单击commandLink时，它只是关闭了.有没有办法让lightBox保持打开状态?

It's just a simple Primefaces lightBox I want to use commandLinks in. Unfortunately it simply closes, when I click a commandLink. Is there a way to keep the lightBox open?

以下是我的代码的示例:

Here an example of what my code looks like:

<ui:composition xmlns="http://www.w3.org/1999/xhtml"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:ui="http://java.sun.com/jsf/facelets"
xmlns:p="http://primefaces.org/ui" template="template.xhtml">

<ui:define name="content">
    <p:lightBox>
        <h:outputLink value="#">
            <h:outputText value="open lightbox" />
        </h:outputLink>

        <f:facet name="inline">
            <h:form>
                <h:commandLink>
                        commandLink
                </h:commandLink>
            </h:form>
        </f:facet>
    </p:lightBox>

</ui:define>

</ui:composition>

推荐答案

使用ajax(异步)请求代替同步请求:

Use an ajax (asynchronous) request instead of a synchronous request:

<h:commandLink ...>
    <f:ajax ... />
</h:commandLink>

或当您已经在使用PrimeFaces时，只需改用<p:commandLink>(默认情况下已使用ajax):

or as you're using PrimeFaces already, just use <p:commandLink> instead (it uses by default already ajax):

<p:commandLink ... />

使用ajax时，默认情况下不会执行任何新的页面替换操作(基本上会将任何内容重置"为默认值).在<f:ajax>的情况下，可以通过render属性来判断组件树的哪些部分应在客户端进行更新，而在<p:commandLink>中应通过update属性进行更新.例如.如果只想渲染/更新父表单，请使用@form.例如

With ajax, by default no fresh page replacement with the response is performed (which basically "resets" anything to defaults). You can in case of <f:ajax> tell by render attribute which parts of the component tree should be updated in the client side and in <p:commandLink> by the update attribute. E.g. if you want to render/update the parent form only, use @form. E.g.

<p:commandLink ... update="@form" />
