我有一个 PrimeFaces 网络应用程序。当我手动添加 jQuery 和插件时，如下所示，
<script type="text/javascript" src="js/jquery-1.7.1.min.js"></script>
<script type="text/javascript" src="js/onebyone/jquery.onebyone.js"></script>
<script type="text/javascript" src="js/onebyone/jquery.touchwipe.min.js"></script>
<script type="text/javascript" src="js/jquery.carouFredSel-5.5.0.js"></script>
然后 PrimeFaces 组件失去了它们的功能和一些样式。例如，<p:dialog>不显示、<p:accordionPanel>不滑动、<p:panelGrid>丢失填充等。
这是如何引起的，我该如何解决？
PrimeFaces 已经捆绑了 jQuery，但是您已经下载并安装了另一个只会与 PrimeFaces 捆绑的 jQuery 冲突的软件。我敢肯定，如果您对 webbrowser 的内置 JavaScript 控制台多加关注和喜爱，您就会看到 JS 错误。而且，如果您通过右键单击在 webbrowser 中查看源代码检查 JSF 生成的 HTML 输出，您会看到另一个jquery.js文件包含在 HTML 中<head>。
您需要删除以下行：
<script type="text/javascript" src="js/jquery-1.7.1.min.js"></script>
如果您的页面不一定使用 PrimeFaces 组件，因此不会自动包含其 jQuery，那么您需要通过适当的<h:outputScript>.
<h:outputScript library="primefaces" name="jquery/jquery.js" />
请注意，使用<h:outputScript>不会在实际使用 PrimeFaces 组件的页面上包含重复的脚本。
编辑2：我进行了手动调试，发现这条线导致了问题，在删除它之后，希望一切恢复正常。
<script type="text/javascript" src="js/main.js"></script>
我实际上并没有收到任何错误或排泄物，但一些 primeface 组件表现得很奇怪。例如，我有一个selectOneMenu用转换器定义的组件。选择一个项目时，表单通过AJAX更新。问题是在选择一个项目后菜单项被破坏（它们代表数字而不是文本），好像转换器不工作并且页面的其他命令停止运行（没有做任何事情）。
另一个问题是datatable每行都有一个触发某些 Ajax 行为的命令链接的组件。单击链接后，数据表的分页不起作用。
从这些问题中，我假设 jQuery 和 ajax 之间存在冲突。
虽然它是一个非常大的文件，但如果有人感兴趣，这是导致麻烦的 js 文件的内容
