如何在参数中使用ui:include?

问题描述

具有JSF 1.2两个页面(one.xhtml和other.xhtml)，
通过以下规则包含在当前页面中:

Have JSF 1.2 two pages(one.xhtml and other.xhtml),
that are included to the current page by following rule:

...
    <c:if test="#{flowScope.Bean.param1}">
        <ui:include src="one.xhtml"/>
    </c:if>

    <c:if test="#{!flowScope.Bean.param1}">
        <ui:include src="other.xhtml"/>
    </c:if>
...

到目前为止one.xhtml与other.xhtml的区别仅在于动作参数:

As far one.xhtml differs from other.xhtml only by action parameters:

one.xhtml:<h:commandLink action="actionOne">
other.xhtml:<h:commandLink action="actionTwo">

one.xhtml:<h:commandLink action="actionOne">
other.xhtml:<h:commandLink action="actionTwo">

是否可以使用一些通用的xhtml?
代替one.xhtml和other.xhtml，就像这样:

Is it possible to use some general xhtml?
Instead of one.xhtml and other.xhtml,something like this:

...
    <c:if test="#{flowScope.Bean.param1}">
        <ui:include src="general.xhtml" param="actionOne"/>
    </c:if>

    <c:if test="#{!flowScope.Bean.param1}">
        <ui:include src="general.xhtml" param="actionTwo"/>
    </c:if>
...

感谢您的帮助.

推荐答案

您需要将<ui:param>嵌套在<ui:include>内，才能将参数传递给包含的文件.

You need to nest <ui:param> inside <ui:include> to pass parameters to the included file.

<ui:include src="general.xhtml">
    <ui:param name="action" value="actionOne" />
</ui:include>

并包含在其中:

<h:commandButton action="#{action}" />

请注意，这仅支持字符串，不支持操作方法.对于后者，您需要升级到JSF 2.0并使用复合组件.

Note that this only supports strings, not action methods. For the latter you would need to upgrade to JSF 2.0 and use composite components.
