我想有条件地输出一些Facelets代码.

为此,JSTL标签似乎工作正常:

<c:if test="${lpc.verbose}">
    ...
</c:if>

但是,我不确定这是否是最佳做法？还有另一种方法来实现我的目标吗？

是否可以在我的.xhtml文件中嵌入注释,这些注释只显示在源代码而不是渲染结果中？我想在文件中包含author,date,...但它们不应该在生成的输出中对最终用户可见.如果我使用标准评论标签 <!-- -->,浏览器会显示它们.

有没有办法只运行一个页面,以便我可以看到生成的html(和css),因为它会向用户看,即使它本质上是非功能性的？独立的JSF页面.我想回顾一下如何在实际编写表单字段之前设置表单以确定它们是否符合用户的观点.我正在使用maven和netbeans但不确定后者是否相关.

我正在使用JSF 2.0并且已经定义了属性javax.faces.FACELETS_SKIP_COMMENTS来跳过JSF代码中的注释,因为有很多其他代码,deveploping注释等.但是我需要在客户端的浏览器中打印一些HTML注释,例如.用于为其他浏览器定义备用条件样式表.

请问有什么办法吗？因为我所有的尝试都失败了

我的Facelet中有以下代码片段:

<h:commandLink id="cmdbtn">
    <f:ajax event="click" execute="@form"
            listener="#{screenShotBean.takeScreenshot}" />
</h:commandLink>

它工作正常,但当我像这样取消它,

<!--        <h:commandLink id="cmdbtn"> -->
<!--            <f:ajax event="click" execute="@form" -->
<!--                    listener="#{screenShotBean.takeScreenshot}" /> -->
<!--        </h:commandLink> -->

然后它抛出以下异常:
