我正在使用Rails，并做了一个导航栏。达到特定宽度后，导航栏会折叠成一个汉堡。我可以单击汉堡标志，而无需在JS中定义任何事件侦听器。我刚刚将其添加到application.html.erb
的头部<meta>
<%= javascript_include_tag 'application' %>
<%= yield :js %>
<meta>
添加后，单击效果很好，但是我的主链接root_path断开了。它会不断进入#index页面，但在空白页面上只会显示“ 2019”，而不是实际的#index页面布局。我修复了在链接中添加get方法的链接，如下所示：
<li><%= link_to 'Home', root_path, method: :get %></li>
仍然不起作用，是我的浏览器后退按钮，这仍然会导致打印有2019的空白页面。有人可以通过单击浏览器的后退按钮解释发生了什么，如何进入上一页？谢谢！
P.S。这是源代码
