引导导航栏切换不工作 [英] Bootstrap navbar toggle not working

问题描述

使用下面的代码我试图创建一个响应式网页布局，减少屏幕大小，将显示导航栏切换按钮，并在选择将列出页面导航。我成功的切换按钮显示，但是，点击，什么也没有发生。我已经审查了各种Bootstrap示例，不能指出为什么我的失败。
任何帮助都会感激。

Using the code below I am attempting to create a responsive web layout, that on reduction of the screen size, a navbar toggle button will display, and on select will list the page navigation. I am successful that the toggle button displays, however on click, nothing happens. I have reviewed various of Bootstrap examples and cannot pin point why mine is failing. Any assistance would be appreciated.

 <nav class="navbar navbar-inverse navbar-fixed-top">
      <div class="container">
        <div class="navbar-header">
          <button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#navbar" aria-expanded="false" aria-controls="navbar">
            <span class="sr-only">Toggle navigation</span>
            <span class="icon-bar"</span>
            <span class="icon-bar"></span>
            <span class="icon-bar"></span>
        <span class="icon-bar"></span>
          </button>

     <div id="navbar" class="navbar-collapse collapse">
          <ul class="nav navbar-nav">
            <li class="active"><a href="#">Home</a></li>
            <li><a href="#about">About</a></li>
            <li><a href="#contact">Contact</a></li>
            <li class="dropdown">
              <a href="#" class="dropdown-toggle" data-toggle="dropdown" role="button" aria-expanded="false">Dropdown <span class="caret"></span></a>
              <ul class="dropdown-menu" role="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>
          <ul class="nav navbar-nav navbar-right">
            <li><a href="../navbar/">Default</a></li>
            <li><a href="../navbar-static-top/">Static top</a></li>
            <li class="active"><a href="./">Fixed top <span class="sr-only">(current)</span></a></li>
          </ul>
        </div><!--/.nav-collapse -->
      </div>
    </nav>  

推荐答案

您可能不包含必要的资源）。

You are probably not including the necessary resources (javascript files).

请尝试将这些行添加到您的代码

try adding these lines to your code

在html页面的头部添加： / p>

in your head section of the html page add:

<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.4/css/bootstrap.min.css
">

在关闭正文标记之前，请添加：

Before you close the body tag add this:

  <script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.4/js/bootstrap.min.js"></script>
