Question

我知道有很多代码exmaples /问题。我搜索了很多，并试图复制/粘贴许多代码。没有任何效果。很抱歉，如果重复或其他什么。

无论如何，我正在尝试在我的固定导航栏中添加一个bootstrap Dropdown菜单。我不希望激活下拉列表，因此我删除了插入符号。

这是我（部分）我的代码：

  <div class="navbar navbar-default navbar-fixed-top" role="navigation">
  <div class="container">
    <div class="navbar-header">
      <button type="button" class="navbar-toggle" data-toggle="collapse" data-target=".navbar-collapse">
        <span class="sr-only">Toggle navigation</span>
        <span class="icon-bar"></span>
        <span class="icon-bar"></span>
        <span class="icon-bar"></span>
      </button>
      <a class="navbar-brand" href="http://getbootstrap.com/examples/navbar-fixed-top/#">SDK Tests Status</a>
    </div>
    <div class="navbar-collapse collapse">
      <span class="glyphicon glyphicon-folder-open room-icn"></span> 
        <a href="#" class="dropdown-toggle" data-toggle="dropdown">Rooms</a>
          <ul class="dropdown-menu">
            <li><a href="#">Action</a></li>
            <li><a href="#">Another action</a></li>
            <li><a href="#">Something else here</a></li>
            <li class="divider"></li>
            <li class="dropdown-header">Nav header</li>
            <li><a href="#">Separated link</a></li>
            <li><a href="#">One more separated link</a></li>
          </ul>


    </div><!--/.nav-collapse -->
  </div>
</div>

任何？谢谢！

我不能相信这一点。 Ryan Olson有一个教程here。将CSS添加到.css文件或您的脑袋。在</body>之前将JavaScript添加到页面的最底部。将HTML放在页面正文中。

CSS：

.navbar-nav .dropdown:hover > .dropdown-menu { 
  display: block; 
}
.navbar-nav .dropdown:hover > a[data-toggle=dropdown] + .dropdown-menu { 
  display: none;
}
.navbar-nav .dropdown.open > a[data-toggle=dropdown] + .dropdown-menu { 
  display: block; 
}

JavaScript的：

<script type="text/javascript">
$(function () {
  var $win = $(window);
  $win.resize(function () {
      if ($win.width() > 768)
          $(".navbar-nav > .dropdown > a").attr("data-toggle", "");
      else
          $(".navbar-nav > .dropdown > a").attr("data-toggle", "dropdown");
  }).resize();
  $(".dropdown-menu").find("input, button").each(function () {
      $(this).click(function (e) {
          e.stopPropagation();
      });
  });
});
</script>

HTML：

 <div class="navbar navbar-default navbar-fixed-top" role="navigation">
  <div class="container">
    <div class="navbar-header">
      <button type="button" class="navbar-toggle" data-toggle="collapse" data-target=".navbar-collapse">
        <span class="sr-only">Toggle navigation</span>
        <span class="icon-bar"></span>
        <span class="icon-bar"></span>
        <span class="icon-bar"></span>
      </button>
      <a class="navbar-brand" href="http://getbootstrap.com/examples/navbar-fixed-top/#">SDK Tests Status</a>
    </div>
    <div class="navbar-collapse collapse">
      <ul class="nav navbar-nav">
        <li class="dropdown">
          <a href="#" class="dropdown-toggle" data-toggle="dropdown"><span class="glyphicon glyphicon-folder-open room-icn"></span> Rooms</a>
          <ul class="dropdown-menu">
            <li><a href="#">Action</a></li>
            <li><a href="#">Another action</a></li>
            <li><a href="#">Something else here</a></li>
            <li class="divider"></li>
            <li class="dropdown-header">Nav header</li>
            <li><a href="#">Separated link</a></li>
            <li><a href="#">One more separated link</a></li>
          </ul>
        </li>
      </ul>
     </div><!--/.nav-collapse -->
  </div>
</div>
