尝试开始学习 Bootstrap。我创建了一些代码来创建响应式菜单，就像这样
<head>

My geuss is that you didn't load jQuery. Place this in your header and see if it works:
我的猜测是你没有加载 jQuery。把它放在你的标题中，看看它是否有效：
<script src="http://code.jquery.com/jquery-latest.min.js" type="text/javascript"></script>
Also i suggest to load the bootstrap js file also in the header, just afterthe jQuery library.
此外，我建议在 jQuery 库之后也在标题中加载 bootstrap js 文件。

It is most likely because the bootstrap.js script relies on jQuery to work. Try including jQuery before bootstrap.js
这很可能是因为 bootstrap.js 脚本依赖于 jQuery 来工作。尝试在 bootstrap.js 之前包含 jQuery

Not sure if this helps but I noticed that on the bootstrap site its tells you to link js files in the footer.
不确定这是否有帮助，但我注意到在引导站点上它告诉您链接页脚中的 js 文件。
I also had wordpress place them in my header as i had to enqueue the scripts in my functions.php file. Once i removed the link to the jquery.js file and bootstrap-min.js in the footer the nav button began to collapse correctly.
我还让 wordpress 将它们放在我的标题中，因为我必须将脚本放入我的 functions.php 文件中。一旦我删除了页脚中 jquery.js 文件和 bootstrap-min.js 的链接，导航按钮开始正确折叠。
