我在bootstrap的下拉菜单中遇到了一些麻烦,但我不知道发生了什么,我的代码有点基于bootstrap的文档,我搜索了另一个答案,但我找不到我的问题所以我会请你帮忙。
PS。我在专栏中做了它只是为了更好地组织它,但我尝试了身体上的另一个例子,它仍然无法正常工作。
我尝试添加ajax,jquery,将其移到头部,但没有任何效果,我该怎么办?
这是我的HTML代码:
<head>
<meta charset="UTF-8">
<title>Frigorifico</title>
<meta name="viewport" content="width=device-width, user-scalable=no, initial-scale=1.0, maximum-scale=1.0, minimum-scale=1.0">
<link rel="stylesheet" href="bootstrap/css/bootstrap.min.css">
<link rel="stylesheet" href="stilos.css">
</head>
<body>
<header>
<div class="container-fluid row form-inline">
<h1 class="col-md-2">Frigorifico</h1>
<nav class="col-md-9">
<ul class="nav justify-content-center">
<li class="nav-item col-md-3">
<a class="nav-link dropdown-toggle" data-toggle="dropdown" href="#" role="button" aria-haspopup="true" aria-expanded="false">Proyectos Actuales</a>
<div class="dropdown-menu">
<a class="dropdown-item" href="#">Proyectos Anteriores</a>
<div class="dropdown-divider"></div>
<a class="dropdown-item" href="#" disabled>Proyectos Actuales</a>
</div>
</li>
<li class="nav-item col-md-3">
<a class="nav-link" href="#">Cronograma Semanal</a>
</li>
<li class="nav-item col-md-3 dropdown">
<a class="nav-link dropdown-toggle" data-toggle="dropdown" href="#" role="button" aria-haspopup="true" aria-expanded="false">Perfiles</a>
<div class="dropdown-menu">
<a class="dropdown-item" href="#">Clientes</a>
<a class="dropdown-item" href="#">Marcas</a>
<a href="#" class="dropdown-item">HablaRangers</a>
</div>
</li>
</ul>
</nav>
<a href="#" class="col-md-1">Mi perfil</a>
</div>
</header>
<script src="bootstrap/js/jquery-3.2.1.min.js"></script>
<script src="bootstrap/js/bootstrap.min.js"></script>

只需在bootstrap.js之前包含popper.js(必需),然后您就可以正常编写代码了 https://jsfiddle.net/tamvo/dog2chqs/
<script src="https://code.jquery.com/jquery-3.2.1.slim.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.11.0/umd/popper.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0-beta/js/bootstrap.min.js"></script>
