javascript - 如何在 Angular 6 中实现 bootstrap scrollspy？

Question

我的代码使用 Angular 6 和 Bootstrap 4 运行。最后，我希望在此设置中运行 bootstrap 的 scrollspy 组件。Bootstrap 需要 jQuery，我不知道如何让它工作。

试试这个代码，如果你在 codepen 或 stackblitz 等网站上构建一个工作示例会更好。这将使我们很容易看到问题。

<header>
  <div class="header-nav" data-spy="scroll" data-target=".navbar">
    <nav id="home-nav" class="navbar navbar-expand-md navbar-light bg-white fixed-top">
      <a class="navbar-brand" href="#">Dashboard</a>
      <button class="navbar-toggler d-lg-none" type="button" data-toggle="collapse" data-target="#navbar_header"
        aria-controls="navbar_header" aria-expanded="false" aria-label="Toggle navigation">
        <span class="navbar-toggler-icon"></span>
      </button>

      <div class="collapse navbar-collapse" id="navbar_header">
        <ul class="navbar-nav ml-auto">
          <li class="nav-item active">
