混合JSF标记和HTML [英] Mixing JSF Tag and HTML

问题描述

我刚开始使用JSF 2.0，但发现自己将JSF标签与标准HTML标签混合使用 以实现所需的布局. 尽管我使用facelets来布局页面，但我认为我不禁要混合使用组件.

I just started out using JSF 2.0 but I found myself mixing JSF tags with standard HTML tag to achieve the desired layout. Although I am using the facelets to layout my pages, but I think I cant help but mix components.

<ui:define name="content">
    <h:form>
        <h:commandButton value="Search" action="#{myBean.handleSearch}"/>
        <h:commandButton value="Reset" action="#{myBean.handleReset}"/>
        <div>
            <!-- Some JSF component -->
        </div>

我一直在思考是否遇到了不良习惯.有任何信息来源吗? 谢谢

I have been thinking if I have been running into bad practice. Any source of info for this? Thanks

推荐答案

这不是一个坏习惯.很好使用JSF组件的唯一原因是可以在JSF组件树中对其进行访问.在这里使用<h:panelGroup layout="block">而不是<div>会是更糟糕的做法.但是，如果要使用容器对其进行内容进行Ajax更新，那么<h:panelGroup id="foo" layout="block">和带有xmlns:jsf="http://xmlns.jcp.org/jsf"命名空间的"html5友好型" <div jsf:id="foo">一样好.

This is not a bad practice. This is perfectly fine. The only reason to use a JSF component is to have access to it in the JSF component tree. It would be a more poor practice to use <h:panelGroup layout="block"> instead of <div> here. But if it was a container of which you'd like to ajax-update its content, then a <h:panelGroup id="foo" layout="block"> would have been perfectly fine as would an 'html5-friendly' <div jsf:id="foo"> with the xmlns:jsf="http://xmlns.jcp.org/jsf" namespace.
