如何将主体包含到标记文件中 [英] How do I include a body into a tagfile

问题描述

我有一个标记文件，打算用作输入模板:

I have a tagfile I intend to use as an input template:

<ui:composition
    xmlns:c="http://java.sun.com/jsp/jstl/core"
    xmlns:f="http://java.sun.com/jsf/core"
    xmlns:h="http://java.sun.com/jsf/html"
    xmlns:ui="http://java.sun.com/jsf/facelets">

    <div class="qr">
        <label>#{question}</label>
        <div class="helpButton"></div>
        <!-- body here -->
        <!-- errors output eventually to go here -->
    </div>

</ui:composition>

它与.taglib.xml和必要的web.xml上下文参数一起存储在我的/WEB-INF/tags文件夹中.

It is stored in my /WEB-INF/tags folder with a .taglib.xml and necessary web.xml context-param.

我了解它可以按如下方式使用:

I understand it could be used as follows:

<g:question question="What is your name?" id="firstname">
    <h:inputText value="#{bean.firstname}" />
</g:question>

目前，这是最基本的形式.我打算使用各种复杂的输入.但是标签等的布局始终需要保持不变.

at the moment this is in its most basic form. I intend to use various and complex inputs. but the layout of the label etc will always need to stay the same.

如何在标签文件中包含<g:question>的正文?

How do I include the body of the <g:question> in the tagfile?

推荐答案

使用<ui:insert>.

<ui:composition
    xmlns:c="http://java.sun.com/jsp/jstl/core"
    xmlns:f="http://java.sun.com/jsf/core"
    xmlns:h="http://java.sun.com/jsf/html"
    xmlns:ui="http://java.sun.com/jsf/facelets">

    <div class="qr">
        <label>#{question}</label>
        <div class="helpButton"></div>
        <ui:insert />
        <!-- errors output eventually to go here -->
    </div>

</ui:composition>

请注意，您甚至可以像通常在模板上那样在标记文件上使用<ui:define name="...">和<ui:insert name="...">.

Do note that you can even use <ui:define name="..."> and <ui:insert name="..."> on tagfiles like as you usually do on templates.
