Javascript似乎並沒有在我的科爾多瓦應用程序工作，我似乎無法弄清楚我在這裏做錯了什麼。我知道肯定在一個正常的瀏覽器的HTML和JavaScript工作正常。JavaScript不工作在科爾多瓦應用程序
以下是我的代碼，我正在創建一個簡單的計算器。

Some notes:
* gap: is required only on iOS (when using UIWebView) and is needed for JS->native communication
* https://ssl.gstatic.com is required only on Android and is needed for TalkBack to function properly
* Disables use of inline scripts in order to mitigate risk of XSS vulnerabilities. To change this:
* Enable inline JS: add 'unsafe-inline' to default-src
