Hi Suresh,
Basically Cordova plugins are used for native devices. You cannot debug your cordova application using Browser. Use Emulator to debug your app. When you say window.openDatabase(), It opens HTML 5 Web SQL Database not the SQLite. You can not get the actual result by using window.openDatabase().
When using the Emulator, you can check/view the database file by extracting db file from the file explorer of Emulator's device monitor.
Regards,
Shakthi
