Question

I am using google map v3 api. I need to detect the drag event on the map. Be it the drag on the map to move to a nearby geographical location or a drag on the marker. I need some javascript function to run when either of the events occur.

Answer 1

Both Map objects and Marker objects have drag events, although you probably want dragend so that you can do something when a user is done dragging rather than do something while a user is dragging.

So you could do something like this:

google.maps.event.addListener(map, 'dragend', function() { alert('map dragged'); } );
google.maps.event.addListener(marker, 'dragend', function() { alert('marker dragged'); } );
