JSF复合组件儿童 [英] JSF composite component childrens

问题描述

有什么方法可以使用EL来检索子列表，以便我可以使用它进行遍历

Is there any way using EL to retrieve a children list so i can iterate through it with

<ul>
   <ui:repeat value="#{Magic El expression}" var="children" >
      <li>
      <p> #{children.title} *</p>
      </li>
   </ui:repeat>
</ul>
<div>
 <cc:insertChildren />
</div>

* perhaps #{children.attrs.title} I don't know?

我在这里想要做的是创建一个Tab复合组件.我知道诸如primefaces之类的库提供tabview等.但是由于扩展了jquery功能，我需要创建自己的库.另外，我正在使用特定的模板. 我需要获取标签标题才能创建标签列表.选项卡是子组件，无论如何我是否可以迭代并获取它们的属性?我的意思是，primefaces会以某种方式做到这一点.

What I'm trying to do here is create a Tab composite component. I know libraries such as primefaces offer tabview etc. Yet I need to create my own because of extended jquery functionality. Plus I'm working with a specific template. I need to get the tabs title to create a list for tabs. Tabs are children components is there anyway i can iterate and fetch their attributes? I mean primefaces does that somehow.

如果您查看他们的html标记，他们将创建一个无序列表，其中包含每个子级tabview组件的标题.如何实现?

If you look at their html markup they create an unordered list with the titles of each children tabview component. How is that implemented?

推荐答案

如果您显示的标记在复合组件内部(我想是)，那么以下是可让您访问其子代的表达式:

If the markup you show is inside a composite component (I guess it is), then the following is the expression that will give you access to its children:

#{component.getCompositeComponentParent(component).children}

稍微相关的问题:在JSF2中，如何知道复合组件是否有子代?
