Same problem -- the URL() function is Python code executed on the server,
but you are attempting to pass in Javascript variables. Should be:
ajax('{{=URL('default', 'location')}}' + '?lat=' + visitor_lat + '&lon=' +
visitor_lon, [], ':eval');
Notice that you must use Javascript in order to construct the URL based on
Javascript variables.
