Question

这是我的代码：

$('li.food').addClass('red');

网站正在制作中。我在app / assets / javascripts文件夹中创建了一个jquery文件hide.js。

这是在我的application.html.erb文件中：

<head>

<%= stylesheet_link_tag 'application', media: 'all', 'data-turbolinks-track' => true %>
<%= javascript_include_tag 'application', 'data-turbolinks-track' => true %>

<%= javascript_include_tag 'hide', 'data-turbolinks-track' => true %>
<%= stylesheet_link_tag 'hide', media: 'all', 'data-turbolinks-track' => true %>

<%= csrf_meta_tags %>
<meta name="viewport" content="width=device-width, initial-scale=1">
<%= render 'layouts/shim' %>

</head>

这是来自Heroku日志的错误消息：

ActionController::RoutingError (No route matches [GET] "/javascripts/hide.js"):
vendor/bundle/ruby/2.2.0/gems/actionpack-4.2.2/lib/action_dispatch/middleware/debug_exceptions.rb:21:in `call'

这是我的application.js文件

//= require social-share-button
//= require jquery
//= require jquery_ujs
//= require hide
//= require hide.js
//= require bootstrap
//= require turbolinks
//= require_tree .

Chrome错误

Failed to load resource: the server responded with a status of 404 (Not Found) ...for stylesheets/hide.css
Failed to load resource: the server responded with a status of 404 (Not Found) ...for javascripts/hide.js

我已尝试bundle exec rake assets:precompile和Heroku run bundle exec rake assets:precompile。

运行bootstrap jquery组件（如Carousel）时没有任何问题。

从搜索开始，似乎我应该做的就是将hide.js放在app / assets / javascripts中，而Rails应该会照顾其余部分，:(

Answer 1

从您的application.js

中删除此行

//= require hide.js

此外，如果您在application.js文件中添加了隐藏js，那么无需使用

单独调用它

<%= javascript_include_tag 'hide', 'data-turbolinks-track' => true %>

Answer 2

找到各种答案here。

$(document).on('page:change', function () {
// Actions to do
});

我无法让Jquery文件工作
