我有一個MVC4 Web API應用程序，其中我有我的Api控制器和Code-First EF5數據庫以及一些JavaScript函數，用於我的應用程序的功能，包括我的Web Api的Ajax調用Service.I在MVC上完成了這個項目，因爲我在VS2012中安裝Cordova時遇到了麻煩，所以我決定使用Eclipse/Android Phonegap platform.Is有一種方法可以調用我的web api服務並能夠檢索我的數據庫數據在我的Android Phonegap應用程序中設計了EF5（MVC4），而無需再次從頭開始。我知道phonegap基本上是Html（JavaScript和Css），但我無法使用與使用MVC4相同的HTML標記調用我的服務。我是一名初學者，請告訴我，如果我正在做的事情是可能的，如果沒有，請告訴我如何去做這件事。 T * 他是我的HTML代碼 *將MVC4 Web API應用程序轉換爲Phonegap Android應用程序

你有什麼樣的麻煩？你可以發佈一些代碼嗎？ –
@Anthony我編輯和粘貼我的HTML代碼，我有我的Ajax，調用我的Web API服務。 –
