javascript - Bootstrap 4 导航栏滚动错误

问题描述

我有一个 Django 登陆页面 + 一些额外的描述页面。

我将带有 bootstrap 4 scrollspy 的导航栏存储在 base.html 文件中，它们指向 home.html 上的 ID。当我在主页上时，它就像在官方 bootstarp示例中一样工作。

1.错误

但是当我转到其他页面时，它只会将此 URL 放在“ http://127.0.0.1:8000/home/services/#pricing ”下并留在“ http://127.0.0.1:8000/home/services/ “网址。

我也收到一条终端错误消息：

Not Found: /docs/4.3/dist/js/bootstrap.bundle.min.js
[13/Jan/2020 16:16:35] "GET /docs/4.3/dist/js/bootstrap.bundle.min.js HTTP/1.1" 404 2509

我见过：

2.错误

在原始示例中，它向用户发送的导航栏区域被突出显示。我的根本没有突出显示。

3. 错误

当我滚动或通过单击它们转到任何导航栏元素时，导航栏不会停留在顶部。

如果我实现以下任何一项，则它涵盖了页面的前几行。为了将导航栏保持在这些行之上，我使用<div class="godown-60" id="godown"></div>了代码留置权。

我试过class=""：

Fixed navbar 
fixed-top 
sticky-top

base.html

<body>
  <header>
    <nav id="navbar-example2" class="navbar navbar-static-top navbar-light bg-light">
      <a class="navbar-brand" href="{% url 'home' %}" > HOME PAGE </a>
      <ul class="nav nav-pills">
        <li class="nav-item">
          <a class="nav-link" href="#about">About</a>
        </li>
        <li class="nav-item">
          <a class="nav-link" href="#services">Services</a>
        </li>
        <li class="nav-item">
          <a class="nav-link" href="#pricing">Pricing</a>
        </li>
      </ul>
    </nav>
...

主页.html

<body>
  <div data-spy="scroll" data-target="#navbar-example2" data-offset="0">
    <h4 id="about">About</h4>
      <a href="{% url 'about' %}">AboutTest</a>
    <p>...</p>
    <h4 id="services">Services</h4>
      <a href="{% url 'services' %}">ServicesTest</a>
    <p>...</p>
    <h4 id="pricing">Pricing</h4>
      <a href="{% url 'pricing' %}">PricingTest</a>
    <p>...</p>
  </div>
