Hi Larry,
Thank you for the reply.
I changed the function to the below but it does not show the
markers...
function processMyData(data) {
var xml = GXml.parse(data);
var markersXml = xml.documentElement.getElementsByTagName
("marker");
var markersXml = [];
for (var i = 0; i < markersXml.length; ++i) {
var name = markersXml[i].getAttribute("id");
var point = new
GLatLng(parseFloat(markersXml[i].getAttribute
("lat")), parseFloat(markersXml[i].getAttribute("lng")));
var markerOnMap = createMarker(point);
markersXml.push(markerOnMap);
markerCluster = new MarkerClusterer(map, markersXml);
}
}
Any ideas why?
About the MarkerManager...do I need that one when I use the
MarkerClusterer?
Many thanks,
/Nimrod
