JQuery 事件不在生产中的 heroku 上工作，而是在开发中工作

问题描述

这似乎是一个常见问题，但我还没有找到适用于我的案例的解决方案.我在 bikes.js.coffee 中有一些 JQuery 可以在本地开发中正常工作.当我推送到 Heroku 时，bikes.js.coffee 中的脚本不会运行.浏览器的 javascript 控制台中没有错误.我正在使用 Rails 4.0.通过阅读，我认为资产的编译方式存在一些错误，但我无法超越.所有图像在生产中都显示良好.

this seems to be a common problem but I haven't found a solution applicable for my case. I have some JQuery in bikes.js.coffee that works correctly in development locally. When I push to Heroku the script in bikes.js.coffee does not run. There is no error in the browser's javascript console. I am using Rails 4.0. From reading around I believe it is some error in the way the assets are compiled but I am unable to get beyond that. All images show up fine in production.

bikes.js.coffee:

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 .

推荐答案

我注意到在 javascript 控制台中有一个未捕获的异常Popover 需要 tooltip.js".这两个 js 文件是引导框架的一部分，并且以错误的顺序编译.我删除了

I notice that in the javascript console there was an uncaught exception "Popover requires tooltip.js". These two js files are part of the bootstrap framework and were being compiled in the wrong order. I removed

//= 需要引导程序/引导程序

因为我目前没有使用任何引导 js 库.删除后，bikes.js 中的 javascript 将按预期工作.

since I am not currently using any of the bootstrap js libraries. After removal, the javascript in bikes.js works as intended.
