Question

我的小屏幕（手机和平板电脑）的导航下拉按钮无效。我已经包含了JS文件，但它仍然无法正常工作。任何人都可以帮助确定为什么这不想与我的js文件连接。

如果您认为这可能是一个问题，我已将它包含在我的CSS链接的顶部。我也尝试将它放在body标签和html标签下。我迷失了该怎么做。那些文件确实存在！

Answer 1

我尝试运行您的代码，用CDN版本替换本地引导程序样式表。当我加载它时，我崩溃了因为jQuery丢失了。在头部添加jQuery后，它起作用了：

<script src="http://code.jquery.com/jquery-3.2.1.min.js" integrity="sha256-hwg4gsxgFZhOsEEamdOYGBf13FyQuiTwlAQgxVSNgt4=" crossorigin="anonymous"></script>

Answer 2

如果要连接CSS上的Bootstrap JS和HTML文件，可以使用Bootstrap CDN轻松完成。

将此添加到您的<head>作为Bootstrap样式表 https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css

这是你的<body>作为Bootstrap JavaScript链接 https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js

同时添加JQuery for Bootstrap以正常工作 https://cdnjs.cloudflare.com/ajax/libs/jquery/3.2.1/jquery.min.js
