切换页面后,Bootstrap下拉列表停止工作 - Rails 4.2

Question

我在我的网站上实现了引导菜单.问题是如果我切换页面菜单变得没有响应,请接受"徽标部分",它将我带回主页.如果我刷新页面,下拉菜单会再次运行.我不知道为什么.

我application.js看起来像:

//= require jquery
//= require jquery_ujs
//= require turbolinks
//= require bootstrap
//= require moment
//= require react
//= require react_ujs

//= require writer/react/panel

我的Gemfile:

source 'https://rubygems.org'

我的导航元素:

<nav class="navbar navbar-default" role="navigation">
  <!-- 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>
    <%= link_to 'Aisis Platform', main_app.root_path, :class=> 'navbar-brand'%>
  </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 navbar-left">
      <li class="dropdown">

        <ul class="dropdown-menu">
          <li><a href="http://writer.aisisplatform.com">Aisis Writer</a></li>
        </ul>
      </li>
      <% if current_user && current_user_is_admin? %>
      <li class="dropdown">
        <a href="#" class="dropdown-toggle" data-toggle="dropdown">User Management <b class="caret"></b></a>

        </ul>
      </li>
      <li class="dropdown">

          <li><%= link_to 'response Annalytics', main_app.response_dashboard_path %></li>
        </ul>
      </li>
      <% end %>
    </ul>

    <ul class="nav navbar-nav navbar-right">

      <% if !current_user %>
      <li><%= link_to "Login", xaaron.login_path, :id => 'nav-login' %></li>
      <li><%= link_to "Register", xaaron.signup_path %></li>
      <% elsif current_user %>
      <li><%= link_to "Profile", xaaron.user_path(current_user) %></li>
      <li><%= link_to "Logout", xaaron.logout_path %></li>
      <% end %>
      <li><%= link_to "Help", '/help_center' %></li>
    </ul>
  </div><!-- /.navbar-collapse -->
</nav>

我90%确定我已经包含了所有需要包含的内容.当我切换页面,刷新页面或切换页面后,控制台不会抛出任何错误 - 尝试单击导航元素.

我错过了什么吗？

我通过div检查器运行上面的html,没有可以检测到的未关闭的标签.

Answer 1

是的,你错过了什么.是的turbolinks.我可以看到你拥有它,但让我解释一下.使用turbolinks,每次单击网站上的公共链接时,浏览器都不会进行完整的页面刷新,它只会发送一个AJAX请求并获取标题和正文.因此,没有page:readyjQuery通常被挂钩的事件,因此jQuery不会获取新到达的DOM结构.

所以,这里有一些选项.

1. 摆脱turbolinks.从你的js文件中删除它们你没事.你将有那些整页重新加载,这可能会减慢你的负载.

2. 在布局中data-turbolinks-track='false'为您的javascript_tag调用添加属性.这将使浏览器在每次调用时获取js文件.

3. 将您的javascript_tag呼叫移至布局的底部body.数字2只是一样的东西.

4. 使用gem就像jquery-turbolinks使用jQuery挂钩所需的回调并获取它来获取新的DOM.
