Google map API to bound beyond poles.

I have found that many Google map in Website used the default map.This default Google map goes beyond the poles while dragging up and down. I have found the code that doesn't exceed the pole while dragging.
Just paste the following code inside you intialize() function of the Google map:

google.maps.event.addListener(map, 'center_changed', function() {checkBounds(); });

var allowedBounds = new google.maps.LatLngBounds(
new google.maps.LatLng(-66.85200239592201, -179.66565397011107),
new google.maps.LatLng(66.903255924231566, 179.57922246681517));
function checkBounds() {
          if(allowedBounds.contains(map.getCenter())) {
            return;
          }
          var mapCenter = map.getCenter();
          var X = mapCenter.lng();
          var Y = mapCenter.lat();
          var AmaxX = allowedBounds.getNorthEast().lng();
          var AmaxY = allowedBounds.getNorthEast().lat();
          var AminX = allowedBounds.getSouthWest().lng();
          var AminY = allowedBounds.getSouthWest().lat();
          if (Y < AminY) {Y = AminY;}
          if (Y > AmaxY) {Y = AmaxY;}
          map.setCenter(new google.maps.LatLng(Y,X));
}

Your map won't go further than poles

Enjoy People!!!
