Question

I just made a simple HTML5 game for mobile webkit. I have made a simple function that inserts the record into the database:

Javascript:

db = openDatabase('highscores', '1.0', 'Whackem Highscores', 2 * 1024 * 1024);
db.transaction(function (tx) {
      tx.executeSql('CREATE TABLE scores (id unique, int,text)');
      tx.executeSql('INSERT INTO foo (id, text) VALUES (?,?,?)',["",score,date1]);
});

It doesn’t seem to do anything!?

How can I fix this?

I also have to make a loop that prints out the highest scores, If you have any advice on something like that, it would also be very helpful.

You probably want something more like:

db.transaction(function (tx) {
      tx.executeSql('CREATE TABLE scores (id INTEGER PRIMARY KEY, score INTEGER, date_added TEXT)');
      tx.executeSql('INSERT INTO scores (score, date_added) VALUES (?,?)', [score, date1]);
});

Note that you’ll have to explicitly DROP your original table.

Each executeSql command takes a success and a failure handler as arguments after the parameter list; adding those will help debug failed queries in the future, as they otherwise fail silently.
