问题 Is there a way to prevent the zoom_change event from being triggered if it occurs due to fitBounds() ? I am having an issue where I need to do a search on the server from client when there is a zoom change to map but every time I call fitBounds() it causes zoom_change to trigger which causes the client to do another search on the server. I am only interested in zoom_change done by users and not programmatically using fitBounds . 回答1: When you do a fitBounds in your program, set a global flag.

问题 http://maps.googleapis.com/maps/api/directions/json?origin=Central+Hong+Kong&destination=Sai+Kung&sensor=false&mode=transit The request works fine without the mode=transit parameter, but the results only include driving directions. With the last parameter added, I get this: "status" : "INVALID_REQUEST" What can I do to make this work? There are definitively transit options available, they are listed in Google Maps. 回答1: INVALID_REQUEST indicates that the provided request was invalid. Common

问题 I have used google maps for displaying some locations using markers, based on the user's current location. User's current location is the center point of the map. The default zoom level is 12 . In default, I displayed markers within 300 miles(approximately in my case) distance only. In that how can I do the following, 1) If decrease the zoom level, I need to increase the distance that should display markers within the increased distance also. how much distance should I increase in miles (i.e.

问题 This is most definitely the same question as Reset bounds on Google Maps API v3 which has no answer. I want to give a user the opportunity to change the area in which they search. I place markers of locations within the zip code (and "touching" zips). If they want to search a different zip they can enter a new zip code and we repeat the process. I follow the google-suggested way of removing markers and such, but have not yet figured out how to clear the map bounds and start all over with a

问题 So, I use Ionic Framework to create mobile app. I use AngularJS, and Google Maps API. Recently, I came across one annoying problem. Whenever the map loads, there is a short delay (but noticeable) in loading map style. Since my map style changes the map to black-and-white, this is problematic. It is visible both when I run app in my browser, as well as in my phone. What is the best way to solve this issue? Here is my map: var styledMap = new google.maps.StyledMapType(MAP_STYLE,{name: "Styled

问题 I'm working on this map and trying to geocode around 150 markers but I'm hitting the geocode limit. How can I add a time delay to avoid hitting the limit? 回答1: This adds a timer to the geocoding so each marker has a delay. // Adding a LatLng object for each city function geocodeAddress(i) { geocoder.geocode( {'address': address[i]}, function(results, status) { if (status == google.maps.GeocoderStatus.OK) { places[i] = results[0].geometry.location; // Adding the markers var marker = new google
