如何在 JSF 2.0 中获取选项卡式窗格组件 (Sun Mojarra)
我现在正在学习/使用 JSF 2.0 (Sun Mojarra),我希望在我的 web 应用程序中有一个选项卡式窗格(单个选项卡可以命名为 General、Detail1、Detail2...)。
我该如何实现这一目标?到目前为止我还没有找到任何相关文档:(
I am learning/using JSF 2.0 (Sun Mojarra) now and I want to have a tabbed pane in my webapp (single tabs could named be General, Detail1,Detail2,...).
How do I achieve this? I haven't found any documetation for this so far :(

JSF 有许多有用的组件,它们或多或少提供了更精美的选项卡面板(以及许多其他面板)。 RichFaces、IceFaces、OpenFaces(以及前面提到的 PrimeFaces)。其中每一个都相当完整,您通常无法混合搭配,因此请查看每一个的演示站点,然后选择您喜欢的一个。我喜欢 RichFaces,但这部分是因为它是 Seam2 上的默认设置,而 Seam2 是我第一次学习 JSF 的地方。框架
There are numerous of useful components for JSF, which provide more or less fancier tab panels (among many others). RichFaces, IceFaces, OpenFaces (and PrimeFaces as mentioned). Each of these is fairly complete and you typically can't mix-and-match, so see the demo sites for each one, and pick the one you like. I like RichFaces, but that's in part because it was the default on Seam2 which is where I first learned JSF. frameworks
如果我可以这么称呼的话,JSF 只是一个“骨干”框架。开箱即用,它为您提供的组件非常少,因为这是创建者的意图 - 他们希望其他人用自己的工作扩展这个框架(只要他们遵循设定的标准)。现在,您可以编写自己的组件,也可以使用 PrimeFaces、ICEFaces、RichFaces 等框架,这些框架已经拥有许多组件。
JSF is only a "backbone" framework if I may call it that way. Out of the box it gives you very few components as this was the intention of the creators - they wanted others to extend this framework with their own work (as long as they follow the set standards, that is). Now you can either write your own components or use frameworks such as PrimeFaces, ICEFaces, RichFaces etc. which already have a number of components.
考虑使用现有的组件库。
PrimeFaces 有一个 TabView 能够添加效果和动态内容。
要实施 PrimeFaces,请遵循说明
Consider using an existing component library.
PrimeFaces has a TabView with ability to add effects, and dynamic content.
In order to implement PrimeFaces, follow the instructions
其他人已经暗示过:Mojarra 是一个基本 JSF 实现。它提供了最小的强制组件集来覆盖大多数现有的 HTML 元素(表单、输入字段和表格)。由于 HTML 不在单个元素中提供选项卡式面板,因此基本的 JSF 实现也不会这样做。
选项卡式面板基本上是一堆链接(或按钮)和要切换隐藏/可见的面板。为了表示链接,通常使用 HTML
元素。为了表示面板,通常使用 HTML
元素。要切换显示/隐藏,基本上有两种方法:
打印每个面板以进行响应,但使用 CSS
display: none
隐藏所有其他面板,并使用 JavaScript 通过设置新面板来切换可见性到display: block
和旧面板到display: none
。打印或者,有条件地将请求的面板打印到响应中。请求哪个面板可以通过链接(或按钮)中的请求参数来确定。
这是方法 1 的基本复制'n'粘贴'n'可运行示例:
您当然可以将
替换为
和by
等等,但只要你不需要将其与支持 bean 和/或 JSF 组件树绑定在一起,那么纯 HTML 也是完全有效的,并且开销较小。您只需引入
即可根据某个列表“动态”重复选项卡和面板。另外,不要忘记添加一个很好的 CSS 镜头,让一切看起来都很美味。这基本上是大部分工作要做的地方。毕竟这基本上也是那些 3rd 方组件库,如 PrimeFaces、RichFaces 和 IceFaces正在做。它们都在单个组件中提供了所需的功能,该组件完成了所有重复且令人眼花缭乱的工作。例如,PrimeFaces 有一个
,RichFaces 有一个
、IceFaces 和
等等。Others have already hinted it: Mojarra is a basic JSF implementation. It offers the minimum set of mandatory components to cover the most of existing HTML elements (forms, input fields and tables). Since HTML does not offer a tabbed panel in a single element, the basic JSF implementation won't do that as well.
A tabbed panel is basically a bunch of links (or buttons) and panels which are to be toggled hidden/visible. To represent links, you usually use the HTML
<a>
element. To represent panels, you usually use the HTML<div>
element. To toggle show/hide either there are basically 2 ways:Print every panel to response, but hide all other panels using CSS
display: none
and use JavaScript to toggle the visiblity by setting the new panel todisplay: block
and the old panel todisplay: none
.Or, print the requested panel to the response conditionally. Which panel has been requested can be be determined by request parameters in the links (or buttons).
Here's a basic copy'n'paste'n'runnable example of way 1:
You can of course replace
<a>
by<h:outputLink>
and<div>
by<h:panelGroup layout="block">
and so on, but as long as you don't need to bind it in the with the backing bean and/or JSF component tree, then just plain HTML is perfectly valid as well and has less overhead.You just have to bring
<ui:repeat>
in to repeat the tabs and the panels "dynamically" based on some list. Also don't forget to throw in a good shot of CSS to make it all look like tasty. This is basically where the most of the work goes in.This is after all basically also what those 3rd party component libraries like PrimeFaces, RichFaces and IceFaces are doing. They all provide the desired functionality in a single component which does all the repeating and eye-candiness job. PrimeFaces for example has a
<p:tabView>
, RichFaces a<rich:tabPanel>
, IceFaces an<ice:panelTabSet>
and so on.
