javascript - 顶部导航栏折叠不起作用

标签 javascript jquery html css twitter-bootstrap

我正在创建一个基于 Bootstrap 的网站，该网站具有垂直菜单，可以通过按钮和顶部栏进行切换，当屏幕尺寸减小时顶部栏可折叠。我设法添加了一个注销链接，但是当屏幕尺寸减小时，注销不会出现在顶部导航栏折叠菜单中。我不确定我哪里出错了

最佳答案

替换你的导航栏 <nav>用这个编码。它现在正在工作。在你的 fiddle 中测试过。

<nav class="navbar navbar-default no-margin">
  <!-- Brand and toggle get grouped for better mobile display -->
  <div class="navbar-header fixed-brand">
    <button type="button" class="navbar-toggle collapsed" data-toggle="collapse" id="menu-toggle">
      <span class="glyphicon glyphicon-th-large" aria-hidden="true"></span>
    </button>
    <button type="button" class="navbar-toggle" data-toggle="collapse" data-target="#text">
      <span class="sr-only">Toggle navigation</span>
      <span class="icon-bar"></span>
      <span class="icon-bar"></span>
      <span class="icon-bar"></span>
    </button>
  </div>
  <!-- navbar-header-->

  <div class="collapse navbar-collapse" id="text">
     <ul class="nav navbar-nav">
      <li class="active">
        <button class="navbar-toggle collapse in" data-toggle="collapse" id="menu-toggle-2"> <span class="glyphicon glyphicon-th-large" aria-hidden="true"></span></button>
      </li>
      <li class="active"><a href="#">Home</a></li>
      <li><a href="#">Profile</a></li>
      <li><a href="#">Messages</a></li>
    </ul>

    <ul class="nav navbar-nav navbar-right">
      <li><a href="#">Lin</a></li>
    </ul>
  </div>
  <!-- bs-example-navbar-collapse-1 -->
</nav>
