Answer 1

I got same problem when was new to phonegap. Try this ,

var db = window.openDatabase("sgpw", "1.0", "PhoneGap Demo", 200000); 

document.addEventListener("deviceready", onDeviceReady, false);

function onDeviceReady() { 

db.transaction(populateDB, transaction_error, populateDB_success);

}

This will then call populateDB function.
If error comes then will call transaction_error.
If successful then will call populateDB_success function.
