我創建了一個django應用程序。在我的應用程序中，我有一個註冊日期字段。爲此我使用jQuery datepicker。它之前工作正常，但今天當我開始我的應用程序由於某種未知原因而無法工作。我無法理解爲什麼它不能在我的代碼中工作，但是當我在一個新的html中單獨給出該腳本時工作正常。它現在顯示的錯誤是datepicker不是一個函數。可以有人看着這個。我將在這裏粘貼我的html代碼。datepicker未定義 - jQuery

您是否更改了創建datepicker的調用匿名函數，因此它不是'$（document）.ready（）'？這種情況對我來說很重要，沒有進一步的審查。 – 2011-04-11 03:53:30
我沒有讓你...可以請你粘貼我的代碼。我是編程中的新手 – 2011-04-11 03:58:01
顯然，使用ready（）方法註冊的onload處理程序不會執行。很少從您的代碼中讀取，而沒有進一步的細節。首先採用您最喜歡的JS調試工具，如Firebug，並自己檢查JS錯誤 - 然後回報。不要指望我們可以遠程讀取你的錯誤信息。慢慢來，提供合理和準確的錯誤信息。 – 2011-04-11 04:00:42
