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

它最有可能使用JSONp，即它包含来自google服务器的脚本，该脚本调用回调函数并将响应传递给该函数。
