I would like to retrieve coordinates and use it in other script and I can not do it from the "bubble". Do you know how for example construct URL that contains in parameters new coordinates of dragged marker? Hello, nice method!

There are two methods to retrieve this sort of data: Javascript and HTTP. If you need to populate a table with geographic coordinates, use the HTTP method. Go on with Javascript if your queries should be done in realtime, on the page. Example of Javascript geocoding: <code>var geocoder = new GClientGeocoder(); Geocoder.getLatLng(address, function(point) { if (!point) { alert(address + " not found"); } else { // a new point object with the coordinates has been set } };</code> Example of geocoding via HTTP is a JSON call to google with parameters sent with GET method. Try following <a href="http://maps.google.com/maps/geo?q=1600+Amphitheatre+Parkway,+Mountain+View,+CA&output=json&oe=utf8&sensor=true_or_false&key=your_api_key" rel="nofollow">this link</a>.

Hi Ray,
try to place the code after the initialization script, to clarify that I call a function named google_buildmap() located in

/lib/google_maps/js/google_maps.js

from the main init function.

My question: - where exactly do you place your short Javascript code, in a standard page with a Google Map? (can you give a simple example?). I tried looking at the source code of your demo page, but could not find your JS code anywhere, (needed to perform "the magic"). Grazie!! Ray SF Hi Giancarlo,

Liked the idea in your blog post:
“How to find the right point in Google Maps
(longitude and latitude)”.

My question:
- where exactly do you place your short Javascript code,
in a standard page with a Google Map?
(can you give a simple example?).

I tried looking at the source code of your demo page,
but could not find your JS code anywhere, (needed to perform “the magic”).

Grazie!!

The situation with the client on the phone explaining me where to put the marker is exactly what I am trying to avoid :-) Thank you very much for the code!

I suppose the map fails to load even if you don't use it in debug mode, so it could be a simple syntax error somewhere. Could you try uncomment it (or create another page with the code uncommented) so we can try to debug it? It would be very interesting, indeed.
