问题 I am trying to build support for tiled vector data into some of our Google Maps v3 web maps, and I'm having a hard time figuring out how to find out which 256 x 256 tiles are visible in the current map viewport. I know that the information needed to figure this out is available if you create a google.maps.ImageMapType like here: Replacing GTileLayer in Google Maps v3, with ImageMapType, Tile bounding box?, but I'm obviously not doing this to bring in traditional pre-rendered map tiles.

问题 I am using the google maps api to get directions with the durationInTraffic option. var request = { origin: start_address, destination: end_address, waypoints: waypts, durationInTraffic: true, optimizeWaypoints: true, travelMode: tmode }; directionsService.route(request, function(response, status) { .... This is working fine with a start and end address with no waypoints, as seen below: My problem is that when i add a waypoint to to route then the "time in current traffic" estimate is no

When I log the variable from_place it returns an object like so: but when I log to_place it returns an object with formatted_address: I realise I'm using autocomplete on the first form and that's affecting it but how do i get to not affect or give me the formatted address? // declare variables var map, infoWindow, placeSearch, autocomplete; // autocomplete form var
