Question

当前，当屏幕最小化时，会显示切换按钮，但是当屏幕为常规尺寸时，我希望能够单击它并查看导航栏的内容。当前单击它不会执行任何操作。没有JS，有没有办法解决这个问题？

这是我的HTML页面：

<html>
  <head>
    <link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.1.3/css/bootstrap.min.css" integrity="sha384-MCw98/SFnGE8fJT3GXwEOngsV7Zt27NXFoaoApmYm81iuXoPkFOJwJ8ERdknLPMO" crossorigin="anonymous">
    <title>Great Songs</title>
  </head>
  <body>
    <nav class="navbar navbar-expand-lg navbar-light bg-light">
      <a class="navbar-brand" href="{% url 'great_songs:great_songs' %}">Great Songs</a>
      <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbar" aria-controls="navbarSupportedContent" aria-expanded="false" aria-label="Toggle navigation">
      <span class="navbar-toggler-icon"></span>
      </button>

      <div class="collapse navbar-collapse" id="navbar">
        <ul class="navbar-nav mr-auto">
          <li class="nav-item">
            <a class="nav-link" href="{% url 'great_songs:artists' %}">Artists <span class="sr-only">(current)</span></a>
          </li>
          <li class="nav-item">
            <a class="nav-link" href="{% url 'great_songs:genres' %}">Genres</a>
          </li>
          <li class="nav-item">
            <a class="nav-link" href="{% url 'great_songs:producers' %}">Producers</a>
          </li>
          <li class="nav-item">
            <a class="nav-link" href="{% url 'great_songs:labels' %}">Labels</a>
          </li>
        </ul>
      </div>
    </nav>

  <div class="container">
  {% block content %}
  {% endblock %}
  </div>
  </body>
</html>

您无需编写自己的代码即可使其工作，但还需要包括bootstraps js库及其依赖项（jQuery + popper.js），在这里您将找到有关如何操作的信息{{ 3}}

如果您对此有任何疑问，请告诉我，我将向您展示如何将其实现到您的代码中

@edit： FYI bootstrap.css，仅为您提供一堆可用于快速样式设计的css类，但除非提供诸如元素悬停或focus之类的css支持的交互，否则它不会提供任何交互性
