Hi Rossko
I understand the async issue now but i'm not sure HOW to implement
your suggestion. Is your reference to a marker manager my array (I
dont actually have a marker manager defined). This being my code
snippet...
GDownloadUrl("genxmlO.php", function(data, responseCode) {
if(responseCode == 200) {
var xml = GXml.parse(data);
var markers = xml.documentElement.getElementsByTagName
("marker");
for (var i = 0; i < markers.length; i++) {
var Name = markers[i].getAttribute("Name");
var Url = markers[i].getAttribute("Url");
var Type = markers[i].getAttribute("Type");
var point = new GLatLng(parseFloat(markers
[i].getAttribute("X")), parseFloat(markers[i].getAttribute("Y")));
Omarker = createMarkerO(point, Name, Url, Type);
MGroup.push(Omarker);
}
} else if(responseCode == -1) {
alert("Data request timed out. Please try later.");
} else {
alert("Request resulted in error. Check XML file is
retrievable.");
}
}); //GDownloadurl
...which bit should I move out? The MGroup.push bit? Appreciate your
patience.
