我想在代码中使用scrollspy功能，但无法正常工作
<nav class="navbar navbar-expand-lg fixed-top navbar-dark" role="navigation">
<div class="container">
<a class="navbar-brand" href="#featured"><h1></h1></a>
<button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarNav" aria-controls="navbarNav" aria-expanded="false" aria-label="Toggle navigation">
<span class="navbar-toggler-icon"></span>
</button>
<div class="collapse navbar-collapse" id="navbarNav">
<ul class="navbar-nav ml-auto">
<li class="nav-item active">
<a class="nav-link" href="#featured">Home</a>
</li>
<li class="nav-item">
<a class="nav-link" href="#mission">Mission</a>
</li>
<li class="nav-item">
<a class="nav-link" href="#services">Services</a>
</li>
</ul>
</div>
</div>
</nav>
和身体标签
<body data-spy="scroll" data-target=".fixed-top">
问题可能出在哪里？
最佳答案
尝试这个
