getting a function to return the response from an ajax request?

[danielnickless]

Hiya,

I'm having a little bit of trouble understanding this - hope you can
help!

I can't seem to write a function which takes arguments, turns these
into a mootools request and then returns the response from the server
side script.

So far i have...

        function text_to_db(text,table,field,id){

                var text_to_db = new Request({method: 'get', url: "../assets/
controllers/text_to_db.php"
                                                                                
, onSuccess: function(response){
                                                                                
        makeChanges(response)
                                                                                
}
                                                                                
})

                var string = 
"text="+text+"&table="+table+"&field="+field+"&id="+id;

                text_to_db.send(string);


                function makeChanges(response){return response};

        }

But it always returns undefined.

I think it has something to do with this thread but i've spent a good
few hours trying to work it out and i'm stumped.

Hope you can help,

Dan
