Question

导航栏在较新版本的bootstrap（v3.3.6）中不起作用，它的问题是javascript部分无法像切换到移动视图和下拉列表那样工作。

当我用V3.0的bootstrap替换它时，代码工作得非常好，但在与3.3.6（CDN和离线）一起使用时不起作用。我已经交叉检查了拼写和目录错误。

根据您提供的代码（如果您在默认情况下执行某些操作，则需要说明这一点）我无法看到它们是如何实际工作的。

您没有将数据目标（data-target="#mobile-collapse"）属性附加到 navbar-collapse div（<div class="navbar-collapse collapse" id="mobile-collapse">）。

相同的HTML适用于使用 v3.0 和 v3.3.6 的以下示例。请参阅Navbar文档。

工作3.0示例

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.0.0/js/bootstrap.min.js"></script>
<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.0.0/css/bootstrap.min.css" rel="stylesheet" />
<div class="navbar navbar-default navbar-fixed-top">
  <div class="container">

    <div class="navbar-header">
      <button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#mobile-collapse">
        <span class="icon-bar"></span>
        <span class="icon-bar"></span>
        <span class="icon-bar"></span>
      </button>
      <a class="navbar-brand">Guru Prasad</a>
    </div>

    <div class="navbar-collapse collapse" id="mobile-collapse">
      <ul class="nav navbar-nav">
        <li class="active"><a href="">Portfolio</a>
        </li>
        <li><a href="">About</a>
        </li>
        <li><a href="">Contact</a>
        </li>
      </ul>
    </div>

  </div>
</div>

工作3.3.6示例

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/js/bootstrap.min.js"></script>
<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css" rel="stylesheet" />
<div class="navbar navbar-default navbar-fixed-top">
  <div class="container">

    <div class="navbar-header">
      <button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#mobile-collapse">
        <span class="icon-bar"></span>
        <span class="icon-bar"></span>
        <span class="icon-bar"></span>
      </button>
      <a class="navbar-brand">Guru Prasad</a>
    </div>

    <div class="navbar-collapse collapse" id="mobile-collapse">
      <ul class="nav navbar-nav">
        <li class="active"><a href="">Portfolio</a>
        </li>
        <li><a href="">About</a>
        </li>
        <li><a href="">Contact</a>
        </li>
      </ul>
    </div>

  </div>
</div>

Navbar在bootstrap v3.0中工作，但在v3.3.6中不工作
