對不起，這是相當的，但代碼是相關的，因爲我不知道問題是什麼，也可能是代碼太難以閱讀我傾向於先寫清理，但希望有人知道發生了什麼。問題是我不能從HTML中的按鈕調用任何函數，因爲它們出來「未定義」。我認爲這可能是他們以某種方式包裝在onDeviceReady（）函數中，因此它們實際上並沒有定義它們消失的實例。但無論我嘗試什麼，我都無法修復它。OnDeviceReady隱藏功能？

也抱歉格式化這整個4空間的東西搞砸了比以前更多。
是否有在控制檯的任何錯誤？ –
唯一的錯誤是當單擊該按鈕時「drawMap（）未定義」。如果按鈕沒有被點擊，一切都很好，包括從ondeviceready（）;調用的drawMap（）函數。 此外，如果我只是堅持「警報（」嗨「）;」在onclick它會觸發，所以它沒有按鈕本身的錯誤。 – DasBeasto
