Question

我试图通过从展示中获取代码来使我的页面上出现primefaces元素，菜单在经过一些修改后运行良好但是selectonemenu拒绝出现。
它没有在布局单元中显示任何内容。这是我的xhtml代码：

Answer 1

您的代码有效。您使用的是哪个版本的primefaces？您正在部署哪个应用服务器？您测试过哪种浏览器？除了selectonemenu之外，页面上还有其他内容吗？

尝试以下方法。使用Glassfish 3上的Primefaces 4。

        <title>Test</title>

        <link type="text/css" rel="stylesheet"
            href="#{request.contextPath}/css/default.css" />
        <link type="text/css" rel="stylesheet"
            href="#{request.contextPath}/css/custom.css" />
    </f:facet>

</h:head>

<h:body>

    <h:form>
 <h:panelGrid columns="1" style="margin-bottom:10px" cellpadding="5"> 
     <p:selectOneMenu>  
        <f:selectItem itemLabel="Select One" itemValue="" />  
        <f:selectItem itemLabel="Option 1" itemValue="1" />  
        <f:selectItem itemLabel="Option 2" itemValue="2" />  
        <f:selectItem itemLabel="Option 3" itemValue="3" />  
     </p:selectOneMenu>
 </h:panelGrid>   
</h:form>       
</h:body>

</f:view>

</html>

Answer 2

问题是我必须将selectonemenu绑定到我拥有的托管bean的属性。

selectonemenu没有出现primefaces
