How geocoder.geocode() works?

Question

My only question is, if browser does not support cross domain AJAX request than How google map api works to get the data.

How following code works ?

<script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=false"></script>
<script type="text/javascript">
geocoder = new google.maps.Geocoder();
geocoder.geocode( { 'address': address}, function(results, status) {
   if (status == google.maps.GeocoderStatus.OK) {
   }
});
</script>

what geocoder.geocode does internally ?

EDIT: Ok they are including http://maps.gstatic.com/intl/en_us/mapfiles/api-3/9/8/main.js

can anyone tell me where they are using JSONP in their JS Code ?

Answer 1

It most likely uses JSONp, i.e. it includes a script from the google servers that calls a callback function and passes the response to that function.
