Sample

var db = new Dexie("FriendsAndPetsDatabase");
db.version(1).stores({
    friends: "++id,name,isCloseFriend",
    pets: "++id,name,kind"
});
db.open(); 
db.transaction("rw", db.friends, db.pets, function(friends, pets, transaction) {
    // Since mode is "rw", we can add objects to the object stores
    friends.add({name: "Måns", isCloseFriend: 1});
    friends.add({name: "Nils", isCloseFriend: 1});
    friends.add({name: "Jon", isCloseFriend: 1});
    pets.add({name: "Josephina", kind: "dog"});

    // In case you need to access the transaction object, here's an example of that:
    transaction.on("abort", function() {
        console.log("Transaction aborted");
    });

    // Since we are in a transaction, we can query the table right away.
    // If this was not in a transaction, we would have to wait for all three add() operations
    // to complete before querying it if we would like to get the latest added data.
    friends.where("isCloseFriend").equals(1).each(function(friend){
        console.log("Found close friend: " + friend.name);
        // Any database error event that occur will abort transaction and be sent to the catch() method below.
        // The exact same rule if any exception is thrown what so ever.
    });
}).catch(function (error) {
    // Log or display the error
    console.error(error.stack || error);
});
