bootstrap 3 rails 4 响应式导航栏“图标栏”未扩展

Question

当我将页面缩小太多时，或者如果我在移动设备上，我的导航栏会变成一个小三行按钮，显然被称为“图标栏”。当我单击或触摸此按钮时，没有任何反应。这是每个平台、手机、笔记本电脑等都存在的问题......

<nav class="navbar navbar-default" role="navigation">
  <div class="container-fluid">
<!-- Brand and toggle get grouped for better mobile display -->
<div class="navbar-header">
  <button type="button" class="navbar-toggle" data-toggle="collapse" data-target="#bs-example-navbar-collapse-1"">
    <span class="sr-only">Toggle navigation</span>
    <span class="icon-bar"></span>
    <span class="icon-bar"></span>
    <span class="icon-bar"></span>
  </button>
 </div>

<!-- Collect the nav links, forms, and other content for toggling -->
<div class="collapse navbar-collapse" id="div-navbar-thing">
  <ul class="nav navbar-nav">
    <% if logged_in? && current_user.status == 'career/education' %>
      <% if current_user.username == 'Curry' %>

  </ul>

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

当我删除类时，图标仍然保留在移动应用程序上，或者如果我缩小页面，但当页面缩小到图标所在的位置时，没有可点击的链接。我想让小 3 行图标栏工作，或者一起删除它。

Answer 1

将您的数据目标更改为“.navbar-collapse”我刚刚在 S.O 的某个地方看到了这个，但找不到它。这应该可以解决问题

Answer 2

您是否启用了 JavaScript 并包含 collapse plugin？您可以在Bootstrap 3 Documentation 中找到看起来可能描述您的问题的评论，特别是

需要 JavaScript

如果禁用了 JavaScript 并且视口足够窄以至于导航栏折叠，则无法展开导航栏并查看 .navbar-collapse 中的内容。

还有

插件依赖

响应式导航栏需要 collapse plugin 包含在您的 Bootstrap 版本中。

Answer 3

代码有错别字

“#bs-example-navbar-collapse-1”为“#bs-example-navbar-collapse-1”
