如何使用页眉/页脚/导航创建可重复使用的模板? [英] How to create a reuseable template with header/footer/navigation?
问题描述
我一直在与JSF一起玩，并且有一个包含页眉/页脚/导航/内容的项目 面板.但是，该项目从第1页转到第2页，依此类推，每个页面都有不同的布局.如何创建可重复使用的模板，使页面之间的外观保持相同，即页眉/页脚/导航保持不变，但内容已更新?
I have been playing with JSF and have a project working that has a header/footer/navigation/content panels. The project, however, goes from page 1 to page 2, etc., with each page having a different layout. How can I create a reusable template that keeps the same look and feel from page to page, i.e., header/footer/navigation stay the same, but content is updated?
推荐答案
这听起来像是主模板的经典案例.在这样的模板中，您放置了所有页面共有的所有内容，然后您的实际页面引用了该模板并填入空白".在某种程度上，它与经典的include相反.
This sounds like a classic case of a master template. In such a template you put everything that's common to all pages and then your actual pages reference this template and "fill in the blanks". In a way it's the reverse of the also classic include.
例如
/WEB-INF/templates/masterTemplate.xhtml:
<!DOCTYPE html>
<html lang="en"
xmlns="http://www.w3.org/1999/xhtml"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:ui="http://java.sun.com/jsf/facelets"
>
<h:head>
<title>
<ui:insert name="title">Some title</ui:insert>
</title>
</h:head>
<ui:include src="header.xhtml"/>
<h:body>
<ui:insert name="content" />
</h:body>
<ui:include src="footer.xhtml"/>
</html>
页面按如下方式使用它，例如
A page uses this as follows, e.g.
/hello.xhtml
<ui:composition template="/WEB-INF/templates/masterTemplate.xhtml"
xmlns="http://www.w3.org/1999/xhtml"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:ui="http://java.sun.com/jsf/facelets"
>
<ui:define name="title">hello</ui:define>
<ui:define name="content">
Hi, this is the page
</ui:define>
</ui:composition>
