Question

我使用bootstrap创建了一个测试文件。我在网页的head部分调用了bootstrap.min.css。

另外，在关闭body标签之前，我调用了几个JavaScript文件。

但是现在我要创建一个切换菜单，这将成为一个下拉菜单，当在移动版本中看到时，切换按钮不起作用。这是切换按钮的代码。

我想知道背后的原因是什么。为什么切换按钮无法正常工作？

Answer 1

您的代码中存在拼写错误，我对其进行了更正。您写了＆＃39; data-ctoggle＆＃39; 而不是数据切换

正确的代码： <button type="button" class="navbar-toggle" data-toggle="collapse" data-target=".navbar-collapse">

Answer 2

检查此行以查看其是否正确指出

<script src="/home/user/Testing/bootstrap/js/bootstrap.min.js"></script>

或

从http://getbootstrap.com/getting-started/#download

下载核心文件

将javascript代码替换为以下

<script src="../../dist/js/bootstrap.min.js"></script>
<script src="../../assets/js/ie10-viewport-bug-workaround.js"></script>

Bootstrap切换菜单在移动视图中不起作用
