【问题描述】：

我正在尝试将 Bootstrap 合并到 Django 项目中。但是，我无法让导航栏按钮在单击后展开。我怀疑 Django 对模板进行分层会导致 Jquery 加载奇怪，因此在单击按钮时从不做任何事情。

下面是我的content_base.html。

{% load static %}
<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="utf-8">
    <meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">
    <!-- Bootstrap CSS -->
    <link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/bootstrap@4.5.3/dist/css/bootstrap.min.css"

    <link rel="stylesheet" href={% static 'css/customizations.css' %}>
</head>
<body>
<!-- NavBar -->
<header>
    <nav class="navbar navbar-dark bg-dark">
        <a class="navbar-brand" href={% url 'home_page:home_page' %}>Home Page</a>
        <button class="navbar-toggler" type="button" data-toggle="collapse"
                data-target="#navbarSupportedContent"
                aria-controls="navbarSupportedContent" aria-expanded="false" aria-label="Toggle navigation">
            <span class="navbar-toggler-icon"></span>
        </button>
        <div class="navbar-collapse collapse">
            <ul class="navbar-nav mr-auto">
                <li class="nav-item active">
                    <!-- Needs the users form path for login when created, filler for now to home -->
                    <a class="nav-link" href={% url 'home_page:home_page' %}>Testing</a>
                </li>
                <li class="nav-item active">
                    <a class="nav-link" href={% url 'home_page:about_page' %}>Another Test</a>
                </li>
            </ul>
        </div>
    </nav>
</header>
{% block content %}
{% endblock content %}

<!-- MATHJAX CDN URLs -->
<!--For notes on MathJax CDNs and recommended practices for using the CDNs

        src="https://cdnjs.cloudflare.com/ajax/libs/mathjax/2.7.7/MathJax.js?config=TeX-MML-AM_CHTML">
</script>
</body>
</html>

然后内容文件将扩展上述内容，看起来像 example_content.html：

{% extends 'content_base.html' %}

{% block content %}
    <head>
        <title>A page title</title>
    </head>
    <body>
    <div>
        <h1>Some Heading</h1>
---
---
    </div>
    </body>
{% endblock %}

我已经删除了 mathjax 的东西，但它并没有改变任何东西。我还尝试只拉下各种 JS 源并在本地加载它们，但仍然没有。非常感谢任何帮助，这似乎应该很简单，但我已经为此努力了几个小时。

标签： bootstrap-4 django-templates navbar

【解决方案1】：

我今天早上开始工作了。这两个是罪魁祸首：

data-target="#navbarSupportedContent"
aria-controls="navbarSupportedContent"

我把它们改成：

data-target="#navbarText"
aria-controls="navbarText"

之后一切正常。
