我对编码还很陌生，我正在尝试用我的新网页弄清楚一些事情。我为 Navbar 使用了 Bootstrap 模板。我删除了它附带的一些链接，并按照我喜欢的方式对其进行了自定义。我的问题是，当我将浏览器缩小到移动尺寸时，右边的开关出现，但当我点击时没有任何反应。此外，当浏览器缩小到移动尺寸时，导航栏上的列表项会被推到左侧并向下堆叠。就像我说的，我对编码很陌生，而且我正在自学。这是我的代码。
<style>
.navbar-brand {
padding-right: 70px;
padding-left: 0px;
}
.navbar-inverse {
height: 75px;
margin-bottom: 0px;
}
.nav li {
padding-right: 30px;
padding-top: 10px;
font-size: 1.1em;
font-weight: 700;
}
</style>
<nav class="navbar navbar-inverse">
<div class="container">
<!-- Brand and toggle get grouped for better mobile display -->
<div class="navbar-header">
<button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#bs-example-navbar-collapse-1" aria-expanded="false">
<span class="sr-only">Toggle navigation</span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
</button>
<a class="navbar-brand" href="#">Brand</a></li>
</div>
<!-- Collect the nav links, forms, and other content for toggling -->
<div class= id="bs-example-navbar-collapse-1">
<ul class="nav navbar-nav">
<li><a href="#">Home</a></li>
<li><a href="#">Services</a></li>
<li><a href="#">Rates</a></li>
<li><a href="#">Locations</a></li>
<li><a href="#">Contact</a></li>
</ul>
</div><!-- /.navbar-collapse -->
</div><!-- /.container-fluid -->
</nav>
最佳答案
这意味着您不包括 jQuery图书馆或您没有正确放置它。你可以visit this link for the basic template正如你在那里看到的，jQuery在 bootstrap.js 之前包括 first/bootstrap.min.js .而这部分<div class= id="bs-example-navbar-collapse-1"> 应该是 <div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1"> ，请注意类 collapse和 navbar-collapse帮助导航栏折叠。
你可以试试这个，如果你想:
