Is thee an api that I could just pass in the street address and get
back the lat and lng like this:
var geocoder = new GClientGeocoder();
var latlng = geocoder.getLatLng(address);
var lat = latlng.lat();
var lng = latlng.lng();
Than I could do some math to the lat and lng variables and put then in
the GLatLng call like this:
var nwLat = lat - offset;
var nwLng = lng + offset;
map.addOverlay(new GPolygon([new GLatLng
(nwLat, nwLng), new GLatLng(42.353486,-71.136582), new GLatLng
(42.350259,-71.136239), new GLatLng(42.350243,-71.140273),new
GLatLng
(42.353383,-71.140434)], "#F62817", 5, 0.7, "#F62817", 1 ));
I'm also new to JavaScript, so please let me know what will work and
what will not.
It looks like GClientGeocoder() doesn't have such a method, only a
call back function that I don't understand how I get the lat and lng
numbers I need to do the math with. I think it was GMarker had the:
var lat = latlng.lat();
var lng = latlng.lng();
That I need, but still don't understand, this should be easier. :-(
Thanks,
Rose
