jQuery加载localhost但不加载Heroku

Question

编辑:看起来无论出于什么原因我的资产没有加载.我的javascript在服务器上返回404错误.

原文:我知道当我在localhost上运行应用程序时,jQuery会加载,因为; 1.我的应用程序工作,以及2.以下代码还告诉我在页面加载时加载jQuery.

if (typeof jQuery != 'undefined') {
  // jQuery is loaded => print the version
  alert(jQuery.fn.jquery);
}

问题是我一推到Heroku,jQuery就行不通了.上面的代码不再运行了,当我尝试运行时,$.post( "/time_records", {current_time: current_time});我得到以下错误;ReferenceError: $ is not defined

当我在Heroku上运行我的Bundler时,它说 Using jquery-rails (3.1.0)

的application.js

//= require jquery
//= require jquery_ujs
//= require turbolinks
//= require_tree .

的Gemfile

source 'https://rubygems.org'

# Bundle edge Rails instead: gem 'rails', github: 'rails/rails'
gem 'rails', '4.0.2'

# Use postgresql as the database for Active Record
gem 'pg'

# Use SCSS for stylesheets
gem 'sass-rails', '~> 4.0.0'

# Use Uglifier as compressor for JavaScript assets
gem 'uglifier', '>= 1.3.0'

# Use CoffeeScript for .js.coffee assets and views
gem 'coffee-rails', '~> 4.0.0'

# See https://github.com/sstephenson/execjs#readme for more supported runtimes
# gem 'therubyracer', platforms: :ruby

# Use jquery as the JavaScript library

# Turbolinks makes following links in your web application faster. Read more: https://github.com/rails/turbolinks
gem 'turbolinks'

# Build JSON APIs with ease. Read more: https://github.com/rails/jbuilder
gem 'jbuilder', '~> 1.2'

group :doc do
  # bundle exec rake doc:rails generates the API under doc/api.
  gem 'sdoc', require: false
end

# Use ActiveModel has_secure_password
# gem 'bcrypt-ruby', '~> 3.1.2'

# Use unicorn as the app server
# gem 'unicorn'

# Use Capistrano for deployment
# gem 'capistrano', group: :development

# Use debugger
# gem 'debugger', group: [:development, :test]

由于您在Heroku上将应用程序联机,请检查Javascript文件是否未在线返回404 HTTP错误.如果是这样,jQuery将永远不会被加载...
这可能是由于您的配置中的几个错误(来自本地配置的绝对文件路径或其他)
