Question

我正在尝试使用Primefaces的Picklist。呈现页面时，Chrome中的javascript引擎无法找到Primefaces对象。我收到以下错误'Uncaught ReferenceError：PrimeFaces未定义'。我错过了在我的.xhtml文件中包含任何资源（js）吗？请指教。感谢。

PrimeFaces会在<h:head>中自动包含必要的JS / CSS资源。

但是，您没有该标签。你有一个“纯HTML”<head>。相应地修复它：

<html>
    <h:head>
        ...
    </h:head>
    <h:body>
        ...
    </h:body>
</html>

此错误也应记录在服务器日志中，如下所示：

One or more resources has the target of 'head' but not 'head' component has been defined within the view

有关创作JSF / Facelets页面的各种正确示例，另请参阅How to include another XHTML in XHTML using JSF 2.0 Facelets?和When to use <ui:include>, tag files, composite components and/or custom components?。

无关具体问题：PrimeFaces是一个基于jQuery的JSF组件库，已经捆绑了jQuery和jQuery UI。您应该从页面中删除手动包含的脚本以避免冲突。另请参阅Adding jQuery to PrimeFaces results in Uncaught TypeError over all place。

立即抓住机会用<link>替换该详细<h:outputStylesheet>。另请参阅How to reference CSS / JS / image resource in Facelets template?

PrimeFaces CSS看起来没什么感觉缺失和JS“未捕获参考错误：PrimeFaces未定义”
