解決：請參見下面引導自定義JavaScript文件不加載（軌道4）
我的最終目標是建立一個Heroku的儀表盤風格的可摺疊側欄我的回答（收縮的Heroku下降到約768px和它出現在我的應用程序中）。但是，我每次都失敗。我正在使用rails 4和Bootstrap 3，它似乎並不具備這種開箱即用功能。
究竟是什麼問題與我的rails應用程序？我無法在這裏加載任何需要JS的東西。我試過在一個document.ready包裝我的JS，但那也沒有奏效。
我一直在這個[無可否認的時候，不是說寫得很好]指南以下內容： http://seegatesite.com/create-simple-cool-sidebar-menu-with-bootstrap-3/
我在我的Gemfile了gem 'jquery-rails，並在我的config/initializers/assets.rb如下：
Rails.application.config.assets.precompile += %w(app.js)
Rails.application.config.assets.precompile += %w(app.css)
我甚至嘗試將所需的JS插入到<script> inside the .html.erb文件中無濟於事。任何線索或對我有用的鏈接？
它看起來好像所有的HTML和CSS都能正常工作，但切換按鈕沒有功能。
這裏是我的app.js：
//= require jquery
//= require jquery_ujs
//= require turbolinks
//= require bootstrap-sprockets
//= require_tree .
//= require highcharts/highstock
//= require highcharts/highcharts
//= require highcharts/highcharts-more
//= require highcharts/modules/exporting
/* off-canvas sidebar toggle */
$("#menu-toggle").click(function(e) {
e.preventDefault();
$("#wrapper").toggleClass("toggled");
});
$("#menu-toggle-2").click(function(e) {
e.preventDefault();
$("#wrapper").toggleClass("toggled-2");
$('#menu ul').hide();
});
function initMenu() {
$('#menu ul').hide();
$('#menu ul').children('.current').parent().show();
//$('#menu ul:first').show();
$('#menu li a').click(
function() {
var checkElement = $(this).next();
if((checkElement.is('ul')) && (checkElement.is(':visible'))) {
return false;
}
if((checkElement.is('ul')) && (!checkElement.is(':visible'))) {
$('#menu ul:visible').slideUp('normal');
checkElement.slideDown('normal');
return false;
}
}
);
}
$(document).ready(function() {initMenu();});
