以编程方式在jsf托管的bean中创建html组件 [英] Programmatically created html components in jsf managed beans

问题描述

我有以下代码：

I have a following code:

<div id="mws-navigation">
    <ul>
        <li><p:commandLink
                value="#{contentMB.msg.welcome_title.value}" actionListener="#{cleanUpMB.alChangeArea}"
                styleClass="mws-i-24 i-home" action="#{welcomeMB.aLoadDashboard}" global="false" /></li>
        <li><p:commandLink
                value="#{contentMB.msg.layout_menu_measures.value}"
                rendered="#{userSessionMB.measureEdit or userSessionMB.measureCreate}"
                styleClass="mws-i-24 i-table-1" global="false" />
            <ul>
                <li><p:commandLink
                        value="#{contentMB.msg.layout_menu_mm_findMeasures.value}"
                        rendered="#{userSessionMB.measureEdit}"
                        actionListener="#{cleanUpMB.alChangeArea}"
                        action="#{chooseMeasureControllerMB.aChoose}" /></li>
                <li><p:commandLink
                        value="#{contentMB.msg.layout_menu_mm_newMeasures.value}"
                        rendered="#{userSessionMB.measureCreate}"
                        actionListener="#{cleanUpMB.alChangeArea}"
                        action="#{newMeasureControllerMB.aNew}" /></li>
            </ul>
      </li>
   </ul>
</div>

我想从后台JSF托管bean中生成。我知道Primefaces存在可以使用的Java组件，并将它们绑定为模型，但我如何生成纯HTML标记：

which I want to generate from the backing JSF managed bean. I know that for Primefaces exist java components that I can use and bind them as a model, but how can I generate pure HTML tags:

<ul>
<div>
...

？

推荐答案

一个简单的方法是从支持bean返回一些HTML：

A simple way would be to return some HTML from the backing bean:

@Named
@RequestScoped
public class HtmlController implements Serializable {

private static final long serialVersionUID = 1L;

    public String getSomeHtml(){
        return "<h1>Some HTML from a bean</h2>";
    }
}

并将其粘贴到JSF部分：

And paste this into the JSF part:

<h:outputText value="#{htmlController.someHtml}" escape="false" />

但是我认为您的情况最好是创建自己的组件，在那里您也可以一些绑定到后台bean。如何做到这一点的一个例子可以找到 here 或查看 Java EE 6教程。

But I think for your case it would be better to create your own component, there you can also do some binding to backing beans. One example how to do that can be found here or take look at the tutorial of Java EE 6 .
