Hi!
I have this code used for adding speedcamera controls in Norway. The
problem is that I dont want the marker to be on the mep before you
make a click. But only one marker must be avaliable aswell so tat
people only add one marker at a time.
Can you help me?
Heres my code:
<script type="text/javascript">
//<![CDATA[
// globals
var map;
var marker;
var places = [ ];
// geocoder variables and constants
var geo = new GClientGeocoder();

reasons[G_GEO_MISSING_ADDRESS] = "Missing Address: The address
was
either missing or had no value." ;
reasons[G_GEO_UNKNOWN_ADDRESS] = "Unknown Address: No
corresponding
geographic location could be found for the specified address." ;
reasons[G_GEO_UNAVAILABLE_ADDRESS] = "Unavailable Address: The
geocode for the given address cannot be returned due to legal or
contractual reasons." ;
reasons[G_GEO_BAD_KEY] = "Bad Key: The API key is either
invalid or
does not match the domain for which it was given" ;
reasons[G_GEO_TOO_MANY_QUERIES] = "Too Many Queries: The daily
geocoding quota for this site has been exceeded." ;
reasons[G_GEO_SERVER_ERROR] = "Server error: The geocoding
request
could not be successfully processed." ;
reasons[G_GEO_BAD_REQUEST] = "A directions request could not be
successfully parsed.";

input.";

could
not compute directions between the points.";
