Question

我想在我的代码中使用scrollspy功能，但它不起作用

<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>

和正文标记

<body data-spy="scroll" data-target=".fixed-top">

哪里可能是问题？
