您好我试图在glassfish服务器和Intellij IDE上使用Java EE建立一个网站。我尝试使用带有下拉菜单的引导程序导航栏,但下拉列表不起作用。 我的架构是changelog
还有我的代码: 1)layout.tag
<%@tag description="Overall Page template" pageEncoding="UTF-8"%>
<%@taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<%@attribute name="title" fragment="true"%>
<!doctype html>
<html lang="en" xmlns="http://www.w3.org/1999/html">

<link rel="stylesheet" href="<c:url value="/css/custom.css"/>"/>
<title>MyChild - <jsp:invoke fragment="title"/></title>

bootstrap CSS工作,但下拉菜单不起作用。如果我点击“源代码”&#39;在firefox中,我可以看到所有需要的文件(bootstrap.min.js等),以便系统知道文件的位置。
我看到我们必须有一个有效的doctype,当我点击&#34;源代码&#34;在firefox上我在标记之前有5个空行。也许问题出在那里?
ps:它适用于CDN。

查看this jsp并注意顺序。我正在使用您提到的所有bootstrap / jquery / popper css和js。并且其正常工作(按预期)。

尝试在末尾的脚本标记后添加以下代码
if( vkCode == 88)
{
...
return 0;
}
