【问题描述】：

我有一个使用 django 模板引擎的非常简单的网站。在这个站点中，我使用 Bootstrap 进行设计和基本 js。 bootstrap 中的 css 组件完全可以工作，但我无法让 js 工作：

    {% load staticfiles %}

    <!doctype html>
    <html lang="en">
        <head>
            <title>
                blah
            </title>

            <!-- Required meta tags -->
            <meta charset="utf-8">
            <meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">

            <link rel="stylesheet" href="{% static 'css/bootstrap.min.css' %}" type="text/css"/>
        </head>

        <body>
            <!-- Navbar -->
            <nav class="navbar navbar-expand-lg navbar-dark bg-dark">
            <a class="navbar-brand" href="/">blah</a>
            <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarTogglerDemo02" aria-controls="navbarTogglerDemo02" aria-expanded="false" aria-label="Toggle navigation">
                <span class="navbar-toggler-icon"></span>
            </button>

            <div class="collapse navbar-collapse" id="navbarTogglerDemo02">
                <ul class="navbar-nav mr-auto mt-2 mt-lg-0">
                <li class="nav-item active">

                <li class="nav-item">
                    <a class="nav-link disabled" href="#">Disabled</a>
                </li>
                </ul>
                <form class="form-inline my-2 my-lg-0">
                <input class="form-control mr-sm-2" type="search" placeholder="Search">
                <button class="btn btn-outline-success my-2 my-sm-0" type="submit">Search</button>
                </form>
            </div>
            </nav>

            <!-- Space between Navbar and Body -->
            <div class="border-row" style="width:100%; margin-bottom: 15px;"></div>

            <!-- Fullscreen Container -->
            <div class="container-fluid" style="min-height:100%; width:100%;">
                <p>hi</p>

            <script src="{% static '/js/jquery.js' %}"></script>

css 和 js 文件被传送到浏览器，如以下日志所示，但我也得到 /200 未找到：

浏览器控制台： browser console

当我点击右边的小条时，什么都不会发生。如果我使用引导程序的 CDN，一切都会正常工作。

我做错了什么？

【问题讨论】：

你在生产服务器上吗
不是它唯一的本地开发

标签： javascript html django twitter-bootstrap bootstrap-4

【解决方案1】：

通过您的浏览器控制台，我们可以确定您的引导程序包存在问题。所以，这与 django 无关。

你可以通过在bootstrap.min.js之前添加这个来解决这个问题：

<script src="https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.12.6/popper.min.js"></script>

【讨论】：

不幸的是，这没有帮助；/
确定吗？你能提供更多代码吗？我的意思是你的 settings.py
我的控制台已经在我的帖子中，这就是我得到的全部 Not Found: /200 条目是什么让我思考
不！您的引导文件有问题。与django无关。
你应该替换你的 bootstrap.min.js 文件，或者你可以按照这个stackoverflow.com/questions/46952775/…

【解决方案2】：

首先加载jquery-3.5.1.slim.min.js，然后是popper.min.js，最后是bootstrap.min.js。

重新排序对我有用

<script type="text/javascript" src="{% static 'bootstrap-4.5.3/js/jquery-3.5.1.slim.min.js'%} "></script>
<script type="text/javascript" src="{% static 'bootstrap-4.5.3/js/popper.min.js'%}"></script>
<script type="text/javascript" src="{% static 'bootstrap-4.5.3/js/bootstrap.min.js'%} "></script>
