Antic,
Remember to use callbacks and closure when you're dealing with time-related
issues such as user input, databases, or remote procedures. I haven't
worked with mysql (only mongo), but the pseudocode would be something like:
var yourfunction = function(response_object){
> open_database(connection_info, function(db){
> db.perform_query("select blah from bloo where bleep",
> function(results){
> response_object.sendSomeData(results.someData());
> });
> });
> }
Notice how closure ensures that the response_objects makes it to the
innermost callback function. It's there that you send the data to the
framework or TCP/IP port or however you're presenting your information to
the user. It would help more to see a code sample.
