I need to calculate the distance and the duration through geocodes using Google Maps (within India). Any code or solution w开发者_如何学编程ould help.

You may want to use the GDirections.getDistance() and GDirections.getDuration() methods, as in the following example:

   var map = new GMap2(document.getElementById("map"));
   var directions = new GDirections(map);

   directions.load("from: Chennai, India to: Mumbai, India");

   GEvent.addListener(directions, "load", function() {

       // Display the distance from the GDirections.getDistance() method:
       document.getElementById('distance').innerHTML += 
           directions.getDistance().meters + " meters";

       // Display the duration from the GDirections.getDuration() method:
       document.getElementById('duration').innerHTML += 
           directions.getDuration().seconds + " seconds";
   });
   </script> 
</body>
