google maps marker LatLng to screen point  fromLatLngToContainerPixel

function MyOverlay(map) {
    this.setMap(map);
}
MyOverlay.prototype = new google.maps.OverlayView();
MyOverlay.prototype.onAdd = function() {}
MyOverlay.prototype.onRemove = function() { }
MyOverlay.prototype.draw = function() { }

//////////////////////////////////////


var overlay = new MyOverlay(map);
google.maps.event.addListener(marker, 'click', function(e,a,b,c) {
     console.log("++++++++++++++console.log(marker)++++++++++++++++++")                                  
                                        
     var latlng=marker.getPosition();
     var pp = overlay.getProjection().fromLatLngToContainerPixel(latlng);
                                        
     console.log(pp);
});

调用overlay.getProjection().fromLatLngToContainerPixel函数将经纬度转换成像素点pp。注意，pp的像素值是参照地图最左上角的那个点计算出来的
