在引导集成之后，Rails表单未提交

Question

我有一份功能齐全的登记表。样式化之后(例如下载模板的html/css/js并放入我的应用程序以使页面看起来更好看)：

1)我的注册页面停止工作。如果我按submit键，什么都不会发生。

• 我引用了这个问题：for submit button not working，它说检查任何语法错误(我认为我没有)
• 我还读到了Javascript缓存的潜在问题。我读到的这两个问题讨论了bootstrap.js中的bootstrap.js()方法，但是删除这些问题对我没有任何帮助。不知道我是不是移走了正确的东西？

下面是我使用的模板所特有的css：

在我的路线档案里，我确实有

devise_for :users 

这是我的用户注册页面new.html.erb

  <%= devise_error_messages! %>
   <div class="row">

                            <div class="form-group col-lg-3">

                                <%= f.password_field :password_confirmation, class: "form-control", required: true %>
                            </div>
                            <div class="form-group col-lg-12">

                        </div>

              </div>
      </div>
<% end %>
<%= render "devise/shared/links" %> 

这个页面显示的很好，但是当我按下提交按钮时什么都不会发生。

这是我的application.js

// This is a manifest file that'll be compiled into application.js, which will include all the files
// listed below.
//
// Any JavaScript/Coffee file within this directory, lib/assets/javascripts, vendor/assets/javascripts,
// or any plugin's vendor/assets/javascripts directory can be referenced here using a relative path.
//
// It's not advisable to add code directly here, but if you do, it'll appear at the bottom of the
// compiled file.
//
// Read Sprockets README (https://github.com/rails/sprockets#sprockets-directives) for details
// about supported directives.

//= require jquery

还有我的application.css.scss

/*

 *
 * Any CSS and SCSS file within this directory, lib/assets/stylesheets, vendor/assets/stylesheets,

 *
 * You're free to add application-wide styles to this file and they'll appear at the bottom of the
 * compiled file so the styles you add here take precedence over styles defined in any styles
 * defined in the other CSS/SCSS files in this directory. It is generally better to create a new
 * file per style scope.

有什么想法吗？

编辑包含基于注释的信息：通过rails s启动本地服务器。Javascript控制台抛出一个错误：

[Error] Failed to load resource: the server responded with a status of 500 (Internal Server Error) (bootstrap-theme.css.map, line 0)

编辑2:我从应用程序目录中删除了所有引导文件，只导入了gems-现在控制台中根本没有错误。只是一些关于意想不到的CSS标记的警告(这只是一个浏览器可兼容性的东西： https://www.quora.com/Why-does-Safari-display-three-warnings-in-Bootstrap)，但是“注册”按钮仍然没有做任何事情。

Answer 1

Nevermind-- JS缓存从来都不是问题。在我的application.html.erb中，我没有正确地产生--我在我的应用程序布局中输入的注释继续到了我的form元素中。当我检查页面源代码并看到html标记被注释掉时，我注意到了这一点。谢谢大家的帮助！
