Question

Here is my code:

var resultSet;

db.transaction(function (tx){
    tx.executeSql('SELECT * FROM table WHERE name = ?', [name], function (tx, results) {
        resultSet = results;
    });
});

console.log(resultSet);

What is logged is “undefined”.

What I am hoping to get is the SQLResultSet object “results” assigned to “resultSet”.

I am sure I am misunderstanding scoping in JavaScript. But this seems like it should work and I can’t find a similar question asked.

Thanks for your time!!

Answer 1

Either transaction or executeSql is an asychronous function, meaning anything involving its result MUST be included in the callback function.
