将JSF与纯HTML混合使用时有什么问题吗？ [英] Is there any problem when I mix JSF with plain HTML?

问题描述

我有下一个代码：

 < li> 
< h：表单呈现=＃{！loginController.session}> 
< h3> Inicio de Sesi& oacute; n< / h3> 
< h：panelGrid columns =2cellpadding =7> 
< h：outputText value =Usuario：/> 
< h：inputText id =loginnamevalue =＃{loginController.loginname}maxlength =16/> 
< h：outputText value =Contrase& ntilde; a：/> 
< h：inputSecret id =passwordvalue =＃{loginController.password}maxlength =16/> 
< h：outputText value =/> 
< h：commandButton value =Iniciar Sesi& oacute; naction =＃{loginController.CheckValidUser}/> 
< / h：panelGrid> 
< / h：表格> 
< / li> 
  

但是当运行页面不显示窗体时，任何人都可以告诉我为什么？如果您使用的是古老的JSF 1.0 / 1.1实现，那么您需要在<<< ; f：verbatim> 这样的标签：

 < f：verbatim>< li> < / F：逐字> 
< h：表单呈现=＃{！loginController.session}> 
< f：verbatim>< h3> Inicio de Sesi& oacute; n< / h3>< / f：verbatim> 
< h：panelGrid columns =2cellpadding =7> 
 ... 
  

否则它们将在生成的文档的顶部<所有JSF组件之前。

如果您使用的是JSF 1.2或更新的实现，那么您应该能够在模板文本中编写纯HTML没有问题，因为它们在组件树中被自动视为逐字记录。表单不被呈现的唯一原因是 LoginController＃isSession（）返回 true ，因为这就是它的呈现属性取决于。

I have the next code:

<li>
    <h:form rendered="#{!loginController.session}">
        <h3>Inicio de Sesi&oacute;n</h3>
        <h:panelGrid columns="2" cellpadding="7">
            <h:outputText value="Usuario: " />
            <h:inputText id="loginname" value="#{loginController.loginname}" maxlength="16" />
            <h:outputText value="Contrase&ntilde;a: " />
            <h:inputSecret id="password" value="#{loginController.password}" maxlength="16"/>
            <h:outputText value="" />
            <h:commandButton value="Iniciar Sesi&oacute;n" action="#{loginController.CheckValidUser}"    />
        </h:panelGrid>
    </h:form>
</li>

But when run that the page doesn't render the form, anybody can tell me why?

解决方案

If you're using the ancient JSF 1.0/1.1 implementations, then you need to wrap HTML in <f:verbatim> tags like so:

<f:verbatim><li></f:verbatim>
    <h:form rendered="#{!loginController.session}">
        <f:verbatim><h3>Inicio de Sesi&oacute;n</h3></f:verbatim>
        <h:panelGrid columns="2" cellpadding="7">
            ...

Otherwise they will end up in the top of the generated document, before all JSF components.

If you're using a JSF 1.2 implementation or newer, then you should be able to write plain HTML in template text without problems since they are automatically taken as verbatim in the component tree. The only cause for the form not being rendered would be that LoginController#isSession() returned true since that's what its rendered attribute is depending on.
