Question

我正在尝试为我的投资组合页面使用Bootstrap 4 Scrollspy功能，但我无法在Codepen中使用它。

我在StackOverflow中搜索过，发现有人在Codeply中使用了这个功能，here’s the link，它运行得很好。

我接受了代码并将其放在Codepen上，但无法使其正常工作：here’s the link。这是HTML。

<body data-spy="scroll" data-target="#navbarCodeply" data-offset="70">
 <nav class="navbar navbar-expand-md fixed-top navbar-light bg-light">
    <div class="container">
      <a class="navbar-brand" href="#">Codeply</a>
      <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarCodeply">
        <span class="navbar-toggler-icon"></span>
      </button>
      <div class="collapse navbar-collapse" id="navbarCodeply">
        <ul class="nav navbar-nav">
            <a class="nav-link" href="#sec1">One</a>
            <a class="nav-link" href="#sec2">Two</a>
            <a class="nav-link" href="#sec3">Three</a>

  </div>

这就是CSS。

body {
  position: relative;
  overflow-y: auto;
  padding-top: 70px; /* padding for fixed navbar */
}

正如您所看到的，当您在Codepen中向下滚动时，导航项不会更改，但在Codeply中它们会更改。

有谁知道什么是错的？

提前感谢您的帮助。

Juan Betancourt。

PS：我认为问题可能出在CSS和JavaScript Pen设置或body标签属性中。

Answer 1

Bootstrap 4需要Popper.js ..

/popper.js/1.11.0/umd/popper.min.js

Codeply在您选择“Bootstrap 4”时自动包含它，但codepen没有。

Scrollspy Bootstrap 4 - 不在Codepen上
