表單首先使用js根據選擇的類別填充產品選擇列表。這工作。然後它應該根據在產品選擇框中選擇的產品來切換不同的div。Rails 4應用程序 - JS與Webrick但未在開發模式下使用Passenger/Apache2
coffeescript文件的第一部分工作正常。如果我使用Webrick服務頁面，但不通過Apache2/Passenger，則第二部分工作。我沒有在日誌文件中發現錯誤，也沒有在IE調試器中發現錯誤（是的，正確） - div不顯示。
有沒有人知道爲什麼部分文件一直工作，另一部分只在某些時候工作？
我認爲這可能是一個資產管道問題，但是這兩個功能都不起作用，對吧？我在開發模式下運行。預先感謝您的幫助。

更新 - 螢火蟲：
當與Apache /客運運行，我得到這個：
Request URL:
http://server/refresh_content?product_id=10
Request Method:
GET
Status Code:
HTTP/1.1 404 Not Found
當的WEBrick運行，我得到這個：
Request URL:
http://localhost:3000/refresh_content?product_id=10
Request Method:
GET
Status Code:
HTTP/1.1 200 OK
當運行Apache的，它是從服務器根服務，而不是應用程序根 - ??
url: "/refresh_content?product_id=" + trial
