我有一个 Bootstrap 导航栏的代码，并且我添加了折叠功能，因此每当您有小屏幕时，它会将页面链接折叠到按钮中，并且每当您按下 btn 时，它都会打开一个下拉菜单，但我遇到了问题单击折叠 btn 没有任何反应，请帮忙!

最佳答案
我发现您的data-toggle属性中缺少-(连字符)
用途:
<button type="button" class="navbar-toggle" data-toggle="collapse"
data-target="#myNavbar">
而不是:
<button type="button" class="navbar-toggle" datatoggle="collapse"
data-target="#myNavbar">
Note: You must include jquery.js & bootstrap.js (located in js folder) files to use this feature.
