这是我的标题。php当我在手机上试用时,导航栏在手机上不起作用。所有菜单都正确显示在桌面屏幕上,但不会显示在选项卡或移动设备中。这是我的密码。

从中删除类“collapse”

<div class="collapse navbar-collapse" id="navbarColor01">

要创建可折叠的导航栏,请使用带有class=“navbar toggle”、data toggle=“collapse”和data target=“#thetarget”的按钮。然后用class=“collapse navbar collapse”将导航栏内容(链接等)包装在div元素中,后跟与按钮的数据目标匹配的id:“thetarget”

<nav class="navbar navbar-expand-md bg-dark navbar-dark">
  <!-- Brand -->
  <a class="navbar-brand" href="#">Navbar</a>

  <!-- Toggler/collapsibe Button -->
  <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#collapsibleNavbar">
    <span class="navbar-toggler-icon"></span>
  </button>

  <!-- Navbar links -->
  <div class="collapse navbar-collapse" id="collapsibleNavbar">
    <ul class="navbar-nav">
      <li class="nav-item">
        <a class="nav-link" href="#">Link</a>
      </li>
      <li class="nav-item">
        <a class="nav-link" href="#">Link</a>
      </li>
      <li class="nav-item">
        <a class="nav-link" href="#">Link</a>
      </li> 
    </ul>
  </div> 
</nav>

此外,还必须包含bootstrap的js。

您的导航栏已隐藏。添加一些按钮(汉堡),显示导航栏:

<div class="col-10 text-right d-md-none">
                <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarColor01" aria-controls="navbarSupportedContent" aria-expanded="false" aria-label="Toggle navigation">
                    <span class="navbar-toggler-icon"></span>
                </button>
            </div>

把它放在你的div之前 ul 。此代码示例来自我的项目-当然,您必须根据项目调整类。

不包括引导的脚本标记。Bootstrap需要javascript来运行其中一些动画。因此,请包含一个引导脚本标记。min.js,还包括jquery。min.js和jquery UI,因为一些动画使用这些。以下是上述脚本标记。快乐编码:)
