reactjs - 在 Gatsby 中使用 Bootstrap Scrollspy

问题描述

我正在尝试在 Gatsby JS 应用程序中使用bootstrap scrollspy 。

到目前为止，在我的主容器 div 中，我添加了这个（index.js）：

 <div className="main-container" data-spy="scroll" data-target=".navbar" data-offset="50">
      <Layout>
      <Header />
</div>

然后对于每个部分都有一个 id，假设active您在滚动到它时添加一个类。但它没有用。

我还尝试在我的主类中添加以下内容：

 <div className="main-container" data-spy="scroll" data-target="#nav-scroll-target" data-offset="0">
      <Layout>
      <Header />
</div>

然后在我的<Navbar/>组件中，我添加了一个 id 以便可以定位：

 <nav id="nav-scroll-target">
      
  </nav>

但这一个也不起作用。知道是什么导致了这个问题吗？

解决方案

你应该有这样的结构：

<!DOCTYPE html>
<html lang="en">
<head>
  <title>Bootstrap Example</title>
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width, initial-scale=1">
  <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.5.2/css/bootstrap.min.css">
  <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>
  <script src="https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.16.0/umd/popper.min.js"></script>
  <script src="https://maxcdn.bootstrapcdn.com/bootstrap/4.5.2/js/bootstrap.min.js"></script>
  <style>
  body {
      position: relative; 
  }
  </style>
</head>
<body data-spy="scroll" data-target=".navbar" data-offset="50">

<nav class="navbar navbar-expand-sm bg-dark navbar-dark fixed-top">  
  <ul class="navbar-nav">
    <li class="nav-item">
      <a class="nav-link" href="#section1">Section 1</a>
    </li>
    <li class="nav-item">
      <a class="nav-link" href="#section2">Section 2</a>
    </li>
    <li class="nav-item">
      <a class="nav-link" href="#section3">Section 3</a>
    </li>
    <li class="nav-item dropdown">
      <a class="nav-link dropdown-toggle" href="#" id="navbardrop" data-toggle="dropdown">
        Section 4
      </a>
      <div class="dropdown-menu">
        <a class="dropdown-item" href="#section41">Link 1</a>
        <a class="dropdown-item" href="#section42">Link 2</a>
      </div>
    </li>
  </ul>
</nav>

<div id="section1" class="container-fluid bg-success" style="padding-top:70px;padding-bottom:70px">
  <h1>Section 1</h1>
  <p>Try to scroll this section and look at the navigation bar while scrolling! Try to scroll this section and look at the navigation bar while scrolling!</p>
  <p>Try to scroll this section and look at the navigation bar while scrolling! Try to scroll this section and look at the navigation bar while scrolling!</p>
</div>
<div id="section2" class="container-fluid bg-warning" style="padding-top:70px;padding-bottom:70px">
  <h1>Section 2</h1>
  <p>Try to scroll this section and look at the navigation bar while scrolling! Try to scroll this section and look at the navigation bar while scrolling!</p>
  <p>Try to scroll this section and look at the navigation bar while scrolling! Try to scroll this section and look at the navigation bar while scrolling!</p>
</div>
<div id="section3" class="container-fluid bg-secondary" style="padding-top:70px;padding-bottom:70px">
  <h1>Section 3</h1>
  <p>Try to scroll this section and look at the navigation bar while scrolling! Try to scroll this section and look at the navigation bar while scrolling!</p>
  <p>Try to scroll this section and look at the navigation bar while scrolling! Try to scroll this section and look at the navigation bar while scrolling!</p>
</div>
<div id="section41" class="container-fluid bg-danger" style="padding-top:70px;padding-bottom:70px">
  <h1>Section 4 Submenu 1</h1>
  <p>Try to scroll this section and look at the navigation bar while scrolling! Try to scroll this section and look at the navigation bar while scrolling!</p>
  <p>Try to scroll this section and look at the navigation bar while scrolling! Try to scroll this section and look at the navigation bar while scrolling!</p>
</div>
<div id="section42" class="container-fluid bg-info" style="padding-top:70px;padding-bottom:70px">
  <h1>Section 4 Submenu 2</h1>
  <p>Try to scroll this section and look at the navigation bar while scrolling! Try to scroll this section and look at the navigation bar while scrolling!</p>
  <p>Try to scroll this section and look at the navigation bar while scrolling! Try to scroll this section and look at the navigation bar while scrolling!</p>
</div>

</body>
</html>

关键部分是data-target:".navbar"可滚动元素的 （<body>在本例中为 tag ）和与完全相同的类名 ( <nav class="navbar ...">) 匹配的 。您需要将此结构调整为您的代码段，将您的更改<nav>为：

 <nav id="nav-scroll-target" className="navbar">
      
  </nav>
