JQuery 事件不在生产中的 heroku 上工作，而是在开发中工作

bikes.js.coffee:

ready = ->
  jQuery ($) ->

  # when the #make field changes
  $("#bike_make_id").change ->

    # make a POST call and replace the content
    make = $("select#bike_make_id :selected").val()
    make = "0"  if make is ""
    jQuery.get "/bikes/update_model_select/" + make, (data) ->
      $("#bikeModels").html data

    false

$(document).ready(ready)
$(document).on('page:load', ready)

应用程序.js

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