end

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
//= require jquery-ui
//= require jquery_ujs
//= require twitter/bootstrap
//= require turbolinks
//= require_tree

这是我的application.scss：

/*
 * This is a manifest file that'll be compiled into application.css,which will include all the files
 * listed below.
 *
 * Any CSS and SCSS file within this directory,lib/assets/stylesheets,vendor/assets/stylesheets,* or any plugin's vendor/assets/stylesheets directory can be referenced here using a relative path.
 *
 * 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.



 *= require jquery-ui
 *= require_tree 
 *= require_self

我感谢任何帮助！
