To analyse the problem, take out the callback function. The callback
function is executed separately, when the geocoder results are
returned.
So your code currently does this:
function showAddress(address) {
var map = new GMap2(document.getElementById("map_canvas"));
var geocoder = new GClientGeocoder();
var risultato = "iniziale";
geocoder.getLatLng(address, ... ); // sends off the request
return risultato;
}
At some point the geocoder gets its result and runs the callback
function, but by that stage your showAddress function has already
returned its risultato variable.
Everything you need to do with the geocoder's result must be within
the callback function.
