Javascript Rails 4 App-JS在开发模式下与Webrick合作，但与Passenger/Apache2合作

表单首先使用js根据选择的类别填充产品选择列表。这很有效。然后，它应该根据在产品选择框中选择的产品切换不同的div

coffeescript文件的第一部分工作正常。如果我与Webrick一起提供页面，而不是通过Apache2/Passenger，则第二部分可以工作。我在日志文件中没有发现错误，IE调试器中也没有（是的，对）-DIV就是不显示

有人知道为什么文件的一部分总是工作，而另一部分只在某些时候工作吗

我认为这可能是一个资产管道问题，但是这两个函数都不起作用，对吗？我在开发模式下运行这个。提前感谢您的帮助

requests.js.coffee

jQuery ->

#//this handles product population based on category select - this works with Webrick and Phusion/Apache2

    $('#request_product_id').parent().hide()
    products = $('#request_product_id').html()
    emptyOption = $('<option />').attr('value', '');
    $('#request_category_id').change ->
        category = $('#request_category_id :selected').text()
        options = $(products).filter("optgroup[label='#{category}']").prepend(emptyOption).html()
        if options
            $('#request_product_id').html(options)
            $('#request_product_id').parent().show()
        else
            $('#request_product_id').empty()
            $('#request_product_id').parent().hide()


#// this should handle <div> toggle based on product select - this works with Webrick, but not Phusion Passenger/Apache2:

$("#request_product_id").change ->
  trial = $("#request_product_id option:selected").val()
  container = $("#dynamic_portion")
  $.ajax
    url: "/refresh_content?product_id=" + trial
    type: "get"
    dataType: "html"
    processData: false
    success: (data) ->
      container.html data

在Webrick中运行时，我得到以下信息：

Request URL:
    http://server/refresh_content?product_id=10

    Request Method:
    GET

    Status Code:
    HTTP/1.1 404 Not Found

Request URL:
    http://localhost:3000/refresh_content?product_id=10

      Request Method:
      GET

    Status Code:
    HTTP/1.1 200 OK

运行apache时，它是从服务器根目录而不是应用程序根目录提供服务-？？

我将ajax url更改为：

url: "/refresh_content?product_id=" + trial

致：

现在它开始工作了。谢谢你，萤火虫

url: "/refresh_content?product_id=" + trial

url: "/requests/refresh_content?product_id=" + trial
