我使用 bootstrap 创建了一个测试文件。我在网页的头部调用了 bootstrap.min.css。
此外，我在关闭 body 标签之前调用了几个 JavaScript 文件。
但是现在我想创建一个切换菜单，当在移动版本中看到时，这将变成一个下拉菜单，切换按钮不起作用。这是切换按钮的代码。
我想知道这背后的原因是什么。为什么切换按钮无法正常工作？

最佳答案
我更正了您的代码中的拼写错误。您写的是 'data-ctoggle' 而不是 data-toggle
正确代码: <button type="button" class="navbar-toggle" data-toggle="collapse" data-target=".navbar-collapse">
