无法使用引导程序创建汉堡包3.3.7

我想制作一个导航栏，当屏幕很小时会变成汉堡包......但只是无法弄清楚它为什么不起作用......我把所有东西在一个折叠标签内，但仍然无法工作。谢谢你的时间！无法使用引导程序创建汉堡包3.3.7

马修，我已经更新了我的答案。您必须添加必要的JavaScript库（jQuery和Bootstrap）才能使导航栏工作！ – Samuel

您必须插入Bootstrap的Javascript以及jQuery库的NavBar才能正常工作！在最后加上body标签。

<!-- jQuery (necessary for Bootstrap's JavaScript plugins) --> 
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.4/jquery.min.js"></script> 
<!-- Include all compiled plugins (below), or include individual files as needed --> 
<!-- Latest compiled and minified JavaScript --> 
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js" integrity="sha384-Tc5IQib027qvyjSMfHjOMaLkfuWVxZxUPnCJA7l2mCWNIpG9mGCD8wGNIcPD7Txa" crossorigin="anonymous"></script>

尽管如此，所有的信息可以在其documentation解释什么是从navbar元素需要被发现。

问题，你可能要问：

你包括在你的页面的CSS和Javascript？
是否有任何控制台日志指示错误
确保您有viewport的元标记。用于确定页面的大小：<meta name="viewport" content="width=device-width, initial-scale=1">
在您的页面上启用了JS吗？

你的页面应该看起来是这样引导的101模板 - 他们的文档中还发现：

<!DOCTYPE html> 
<html lang="en"> 

<head> 
    <meta charset="utf-8"> 
    <meta http-equiv="X-UA-Compatible" content="IE=edge"> 
    <meta name="viewport" content="width=device-width, initial-scale=1"> 
    <!-- The above 3 meta tags *must* come first in the head; any other head content must come *after* these tags --> 
    <title>Bootstrap 101 Template</title> 

    <!-- Bootstrap --> 
    <link href="css/bootstrap.min.css" rel="stylesheet"> 

    <!-- HTML5 shim and Respond.js for IE8 support of HTML5 elements and media queries --> 
    <!-- WARNING: Respond.js doesn't work if you view the page via file:// -->

     <script src="https://oss.maxcdn.com/respond/1.4.2/respond.min.js"></script> 
    <![endif]--> 
</head> 

<body> 
    <nav class="navbar navbar-default"> 
     <div class="container-fluid"> 
      <!-- Brand and toggle get grouped for better mobile display --> 
      <div class="navbar-header"> 
       <button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#bs-example-navbar-collapse-1" aria-expanded="false"> 
      <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="#">Brand</a> 
      </div> 

      <!-- Collect the nav links, forms, and other content for toggling --> 
      <div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1"> 
       <ul class="nav navbar-nav"> 
        <li class="active"><a href="#">Link <span class="sr-only">(current)</span></a></li> 
        <li><a href="#">Link</a></li> 
        <!-- etc... --> 
       </ul> 
      </div> 
      <!-- /.navbar-collapse --> 
     </div> 
     <!-- /.container-fluid --> 
    </nav> 

    <h1>Hello, world!</h1> 

    <!-- jQuery (necessary for Bootstrap's JavaScript plugins) --> 
    <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.4/jquery.min.js"></script> 
    <!-- Include all compiled plugins (below), or include individual files as needed -->

</body>

感谢您的快速申请！我的一切都在我的HTML中。这里的问题是，当屏幕变小时，它实际上显示为汉堡包图标，但是当点击图标时，什么都不会发生...... – 2341047123413331

你的控制台中是否有任何日志？这将表明您是否遇到JS问题 – Samuel

您还可以检查并确保您包含jQuery库。如果没有包含jQuery，你会看到一个错误 – Samuel
