Thanks very much for your comments.
I managed to get it working before you replied doing the following
although I'm still using 'this':
if(calculateHaversineDistance(...) <= 1){ //1mile radius
if(this["store" + i] == null){
this["store" + i] = new GMarker(point2, {icon:icon});
map.addOverlay(this["store" + i]);
popup(this["store" + i], image, markers[i].getAttribute
("latitude"), markers[i].getAttribute("longitude"));
}
} else {
if(this["store" + i] != null){
map.removeOverlay(this["store" + i]);
this["store" + i] = null;
}
}
I tried changing all the "this"es to "markerArray" but it didn't work
but that might be because I don't know how to call the value once I've
assigned it? markerArray.store[i]?
Ok I will think about using something different like a store_id
although at the moment I am just doing an MSc project of a proof of
concept so I only need to demonstrate my idea.
With regards to hide/show I got it to work sort of but it was
extremely slow and took a long time to decide which markers to hide/
show.
Regards.
