移动菜单栏不工作引导模板

Question

由于某种原因，我的移动菜单无法正常工作。代码如下：

<nav class="navbar navbar-default">
<div class='container'>
    <div class="navbar-header">
        <button type="button" id='navbar-toggle' class="navbar-toggle collapsed" data-toggle="collapse" data-target="#bs-example-navbar-collapse-1">
            <span class="sr-only">Toggle navigation</span>
            <span class="icon-bar"></span>
            <span class="icon-bar"></span>
            <span class="icon-bar"></span>
        </button>
        <div class="brand">
        <a href="../index"><img src="assets/img/transparentlogo.png" alt="logo"></a>
        </div>
    </div>
    <div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1">
        <ul class="nav navbar-nav navbar-left">
            <li><a href="index">Home</a></li>
            <li><a href="services">Services</a></li>
            <li><a href="about">About</a></li>
 
            <li><a href="contact">Contact</a></li>
        </ul>
        <ul class="nav navbar-nav navbar-right">
            <li><a href="contact" class="book">Contact Us</a></li>
        </ul>
    </div>
</div>

非常感谢您抽出宝贵时间阅读这篇文章！

如果您使用 bootstrap 4.6 或某些较低版本，则使用 jquery 版本，然后将 jquery 放置在您的身体末端，例如

  <script src="....................."></script>
  <script src="....................."></script>
     <script src="your jquery"></script>

现在成这个地方

     <script src="your jquery"></script>
  <script src="....................."></script>
  <script src="....................."></script>
