SOLVED: See my answer below
我的最终目标是在我的应用程序中构建一个 Heroku 仪表板样式的可折叠侧边栏(将 heroku 缩小到大约 768 像素，然后它就会出现)。然而，我每次都失败了。我使用的是 Rails 4 和 Bootstrap 3，它们似乎不具备开箱即用的能力。
我的 Rails 应用究竟出了什么问题？我无法在此处加载任何需要 JS 的内容。我试过将我的 JS 包装在 document.ready 中但这也没有用。
我一直在关注这个[诚然很旧，写得不是很好]指南: http://seegatesite.com/create-simple-cool-sidebar-menu-with-bootstrap-3/
我有 gem 'jquery-rails在我的 Gemfile ，并在我的 config/initializers/assets.rb 中包含以下内容:
Rails.application.config.assets.precompile += %w( app.js )
Rails.application.config.assets.precompile += %w( app.css )
我什至尝试将所需的 JS 插入 <script> inside the .html.erb` 文件无效。对我有什么线索或有用的链接吗？
似乎所有 HTML 和 CSS 都运行良好，但切换按钮没有任何功能。
这是我的 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();});

最佳答案
已通过将 JavaScript 文件引用移动到页面底部来修复。将更改问题标题，以便人们更容易找到这可能有所帮助。
<%= stylesheet_link_tag 'app', media: 'all' %>
<%= javascript_include_tag 'app' %>
