问题 How can I get distance(in kms) from mapCenter() to start/end position of map using Google Maps Javascript ? Is there a way to do this? 回答1: You probably looking for a getBounds function: Returns the lat/lng bounds of the current viewport. If more than one copy of the world is visible, the bounds range in longitude from -180 to 180 degrees inclusive. If the map is not yet initialized (i.e. the mapType is still null), or center and zoom have not been set then the result is null or undefined.

问题 Given a latitude/longitude, how can I get the name of the place at that location using Google Map's JS API? The Geocoder.geocode(..) seems to be the way to go, but am not sure what's the best way to get the exact location name out of the API results. 回答1: Use the Geocoding API for mapping locations to addresses and addresses to locations. http://code.google.com/apis/maps/documentation/javascript/services.html#Geocoding Geocoder.geocode( { 'latLng': latLngObject }, callback); The callback

问题 I would like to get a list of all cities I might pass on my way between point A and point B Input - point A as origin point B as destination Output: Route between point A and point B (that's obvious) AND list of cities / towns / places that are closer than X miles to my route. I would like to present the user a list of possible waypoints to consider (points of interest, historic sites, parks, etc) Any ideas how to do that? 回答1: I believe you'd need to do this in a two-stage process: The first
