jquery - 在桌面 View 上看到切换按钮

<nav class="navbar navbar-expand-md navbar-light bg-primary">
  <a class="navbar-brand" href="#">Brand</a>
  <button type="button" class="navbar-toggle" data-toggle="collapse" data-target="#navbarSupportedContent">
        <span class="navbar-toggler-icon"></span>
      </button>
  <div class="collapse navbar-collapse" id="navbarSupportedContent">
        <ul class="navbar-nav mr-auto">
        <li class="nav-item active">Home</li>
    </ul>
    </div>
</nav>

使用上面的代码，当我在桌面上查看页面时，我仍然可以看到切换按钮

最佳答案

您在切换按钮中使用了错误的类名。使用navbar-toggler代替navbar-toggle
