Javascript JQuery事件在heroku上的工作不是在生产中，而是在开发中

这似乎是一个常见的问题，但我还没有找到适合我的情况的解决方案。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。我使用的是Rails 4.0。从周围的阅读中，我相信在资产的编译方式上存在一些错误，但我无法超越这一点。所有的图像在制作中都表现得很好

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)

当我运行本地服务器和“查看源代码”时，我得到的是：

您应该在production.rb中设置config.assets.compile=true

这很可能是路径问题。在jquery中，您可以参考'jquery.get'/bikes/update_model_select/“+make，（data）->$（“#bikeModels”）.html data'，

config.cache_classes = true
  config.eager_load = true
  config.consider_all_requests_local       = false
  config.action_controller.perform_caching = true
  config.serve_static_assets = true
  config.assets.js_compressor = :uglifier
  config.assets.compile = false
  config.assets.digest = true
  config.assets.version = '1.0'
  config.log_level = :info
  config.i18n.fallbacks = true
  config.active_support.deprecation = :notify
  config.log_formatter = ::Logger::Formatter.new

也许这没有在您的服务器上获得正确的路径。查看是否可以将get的结果输出到控制台以确认它是否工作。你永远不知道，它可以像添加一个句号一样简单，即“jQuery.get”。/bikes/update\u model\u select/“+make，（data）->

---

$（“#bikeModels”）.html数据“

检查开发人员工具中的网络选项卡。您是否看到失败的资源

---

不管为什么，您可能希望在production.rb中配置.service\u static\u assets=true。Heruko可能不会为您提供它们。

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。我搬走了

/=需要引导/引导

---

因为我目前没有使用任何引导js库。删除后，bikes.js中的javascript可以正常工作。

您必须运行rake任务

rake资产：预编译

然后转到production.rb文件并设置

config.service\u static\u assets=true

---

这应该可以解决问题。

这是我的假设。我曾经在Salesforce平台上使用过Heroku，我也遇到过同样的问题。因为salesforce已经在内部使用

$

对象，所以jQuery代码都不起作用。使用jQuery的

noConflict（）

解决了我的问题。希望这至少有助于解决这个问题

 var j$ = jQuery.noConflict();

 or

 (function(j$){

 })(jQuery);

---

我这样做了，但仍然得到相同的结果。没有失败的资源。我已经将config.service\u static\u assets设置为true，但这并不能解决问题。我添加了一个句号，但没有结果。我在bikes.js中添加了一些console.log行，但它们在浏览器js控制台中没有输出任何内容。。。。
