I found a very good tutorial which put the markers from any IP address. (google maps) http://lab.abhinayrathore.com/ipmapper/
I would like to modify this code: http://lab.abhinayrathore.com/ipmapper/ipmapper.htm . I have more than 500 markers in the same area, and I would like to make groups, something like this: http://google-maps-utility-library-v3.googlecode.com/svn/tags/markerclustererplus/2.0.9/examples/simple_example.html
So I modified the original code I put the 37. Line this code:
var markerCluster = new MarkerClusterer(IPMapper.map, ipArray);
I think this line make the groups, but nothing happened.
Can anybody help me what do I wrong?
