Pete,
Thank you for your kind answer and patience with my ignorance of the
finer aspects of Javascript!
I have spent several hours trying to work this out and am getting
nowhere. I have a time-sensitive project, so I need to ask for more help.
Why doesn't the following work? Is it necessary to specify another page
for the return json, or can a script on the same page process it?
Thanks!!!
- Ron

Hi there,
Whilst capturing a web service request and parsing it's data is not a
Google Maps API related question, I'll attempt to answer as best as
possible for your current query.
Firstly, using a framework like JQuery makes this task extremely
simple, with their $.getJSON method. For documentation see:
http://api.jquery.com/jQuery.getJSON/
You can then write some code to fetch the feed, and store it in a
"data" variable
$(document).ready(function() {
$.getJSON("http://localhost/myService.aspx, function(data) {
parseMarkerList(data); //data = JSON returned
});
});
Your parseMarkerList(data) function can then loop through the JSON
returned, and pull out nodes such as Latitude, Longitude etc,
something such as:
function parseMarkerList(data) {
for (var i=0; i< data.length; i++) {
var lat = data[i].Latitude; // Where Latitude is the node name
var lng = data[i].Longitude; // Where Longitudeis the node
name
createMarker(lat, lng);
}
}
The createMarker function can then be a simple function that drops
markers on the map, see:
http://code.google.com/apis/maps/documentation/javascript/examples/marker-simple.html
Hope this has helped you.
The key is passing your data object from the request's response, to
the function that will iterate through the feed.
Using this technique you can drop hundreds of markers with no
additional code.
Cheers
Pete

I can't find documentation on how to capture the reply from Web
Service Request.
We want to set the json return array to a variable so we can parse the
map data we need to then build the cost to make a map.
Ideas?
