            icon:icon,
        });
        if(i==0)
        { 
        map.setCenter(marker.getPosition())
        }
        google.maps.event.addListener(marker,'mouseover', (function(marker,content,infowindow){ 
          return function() {
              infowindow.close();
              infowindow.setContent(content);
              infowindow.open(map,marker);
              jQuery("#info"+obj.customer_id).focus();
          };
          })(marker,content,infowindow)); 
        google.maps.event.addListener(marker,'mouseout',  (function(marker,content,infowindow){ 
           return function() {
          };
          })(marker,content,infowindow));
