My code:
function onSuccess(transaction, resultSet) {
console.log('Query completed: ' + JSON.stringify(resultSet));
}
function onError(transaction, err) {
console.log("Error : " + err.message);
}
function createTBinventorymastercatalogue(tx) {
var query = "";
query += "CREATE TABLE IF NOT EXISTS INVENTORY_MASTER_CATALOGUE(SysPk_InvtyCat,SysFk_Invty_InvtyCat);";
tx.executeSql(query, [], onSuccess, onError);
tx.executeSql("INSERT INTO INVENTORY_MASTER_CATALOGUE(SysPk_InvtyCat, SysFk_Invty_InvtyCat) VALUES (?,?)", ['dummydata-pk', 'dummydata-fk'], onSuccess, onError);
}
This is what's in my JavaScript console:
Query completed: {}
Query completed: {}
Uncaught TypeError: Cannot read property 'message' of undefined
Two queries completed, so I guess it successfully created and inserted. The data show when I try to display them.
But then isn't it supposed to show some data inside the {}?
And I don't know why I get:
Uncaught TypeError: Cannot read property 'message' of undefined
Even though the data got inserted. The 2 queries above are the only queries that run when the app starts.
I have other queries but they only run when a button is clicked so the error could not have been caused by those. I don't know where the third log is from, and why is 'message' is undefined?

Your success/error callbacks are reversed when calling db.transaction():
db.transaction(createTBinventorymastercatalogue, onSuccess, onError);
For some reason, that method takes the error callback first.
Swap them around and all is well:
var dbSize = 5 * 1024 * 1024; // 5MB
var db = openDatabase("Todo", "", "Todo manager", dbSize, function() {
console.log('db successfully opened or created');
});
db.transaction(createTBinventorymastercatalogue, onError, onSuccess);
function onSuccess(transaction, resultSet) {
console.log('Query completed: ' + JSON.stringify(resultSet));
}
function onError(transaction, err) {
console.log("Error : " + err.message);
}
function createTBinventorymastercatalogue(tx) {
var query = "";
query += "CREATE TABLE IF NOT EXISTS INVENTORY_MASTER_CATALOGUE(SysPk_InvtyCat,SysFk_Invty_InvtyCat);";
tx.executeSql(query, [], onSuccess, onError);
tx.executeSql("INSERT INTO INVENTORY_MASTER_CATALOGUE(SysPk_InvtyCat, SysFk_Invty_InvtyCat) VALUES (?,?)", ['dummydata-pk', 'dummydata-fk'], onSuccess, onError);
}
