如何在没有 bootstrap.js 的情况下使 Bootstrap 导航栏菜单在移动设备上可以展开

导航栏

<nav class="navbar navbar-expand-lg navbar-light"> 
  <div class="container">        
    <a class="navbar-brand d-flex align-items-center" href="/">         
      <img class="me-1" height="30" src="/assets/img/logo.png">
    </a>
    <button class="navbar-toggler" type="button" data-bs-toggle="collapse" data-bs-target="#navbarSupportedContent" aria-controls="navbarSupportedContent" aria-expanded="false" aria-label="Toggle navigation">
      <span class="navbar-toggler-icon"></span>
    </button>
    <div class="collapse navbar-collapse" id="navbarSupportedContent">   
      <ul class="navbar-nav">
        <li class="nav-item ms-2">
          <a class="nav-link" href="/themes/">Nav Item</a>
        </li>
        <li class="nav-item ms-2">
          <a class="nav-link" href="/themes/theme-installation/">Nav Item</a>
        </li>
        <li class="nav-item ms-2">
          <a class="nav-link" href="/contact/">Nav Item</a>
        </li>
        </ul>
    </div>
  </div>
</nav>

代码

<script src="https://code.jquery.com/jquery-3.6.0.min.js"></script>

<script>
$('.navbar-toggler').click(function(){
$( ".collapse" ).toggleClass('show');
})
</script>
