google-maps-api-3

问题 I'm building a fully dynamic website using jquery/javascript, ajax and php. When I click on a navigation link, the browser opens that page using ajax. So basically all pages are loaded within the same index.php. If I go to 'Location' tab, where I have a google map, it will load the Google Maps script dynamically (adding a script tag to the body). <script type="text/javascript" src="https://maps.googleapis.com/maps/api/js?v=3.exp&callback=initialize"></script> This script is loaded

问题 I wrote simple application which draws route between two locations on MapKit. I am using Google Map API. I used resources I found online and here's the code I am using to make request to Google: _httpClient = [AFHTTPClient clientWithBaseURL:[NSURL URLWithString:@"http://maps.googleapis.com/"]]; [_httpClient registerHTTPOperationClass: [AFJSONRequestOperation class]]; [_httpClient setDefaultHeader:@"Accept" value:@"application/json"]; NSMutableDictionary *parameters = [[NSMutableDictionary

问题 I am in the midst of converting old googlemap v2 code to v3 and it looks if v3 is much slower than v2? Most of my code change is just replacing G with google.maps. (GMarker to google.maps.Marker) Any tips or tricks how to speed things up?? 回答1: The solution might be as simple as experimenting with different versions of the v3 API by trying v=3.4 and v=3.5 in your links that load the API like so: <script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=false&v=3.5"><

问题 Is there any convenient way to compute the direct (shortest) distance between Polyline (the route generated by Google Directions) and markers that are NOT situated on that polyline? The only way I found out is to cycle through Polyline.getPath() vertices manually to calculate the shortest distance but it seems to be a bit harsh: var path = routes[0].overview_path; for (var i = 0; i < data.points.length; i++) { var latLngA = new LatLng(data.points[i].lat, data.points[i].lng); var shortest

问题 I'm trying to make a map that doesn't wrap horizontally, using the Google Maps API V3. So instead repeating the map side-by-side again and again, I want to show it only once. I got that to work by providing a custom getTileUrl function for google.maps.ImageMapType But when I add overlays (like markers or polygons), those still are repeated horizontally. How can I stop the overlays from being repeated horizontally? Edit Here's an image demonstrating the problem: I was thinking of somehow

问题 I use this code to generate static images from Google API, but I have too many requests, so sometimes I get overuse from Google. string latlng = location.Latitude + "," + location.Longitude; string path = "http://maps.googleapis.com/maps/api/staticmap?center=" + latlng + "&zoom=16&size=200x200&maptype=roadmap&markers=color:blue%7Clabel:S%7C" + latlng + "&sensor=false"; Is it possible to call this from C# to generate and save images? I can't find way to get an image object. 回答1: using

问题 I am developing an application which uses google maps api v3 to show markers and infowindows. Well, I have N markers stored within an array and a global infowindow used to show some information. The infowindow contents are shown simply by clicking a marker, created in this way: /* global js stuff */ var g_map = new google.maps.Map(document.getElementById('map-canvas'), mapOptions); var g_current_popup = new google.maps.InfoWindow({ content: "" }); var g_markers = []; /* create marker function

问题 Is there a way to detect when a user enters and exits StreetView in Google Maps under API v3? I want to trigger an existing 'Hide Menu' function when the user enters StreetView (as the menu isn't relevant) and then re-show the menu when they exit. 回答1: Observe the visible_changed -event of the streetView, the visible -property will be true or false (open or closed) function initialize() { var mapOptions = { center: new google.maps.LatLng(52.5498783, 13.425209), zoom: 8 }; var map = new google

问题 I have an map based android app and am providing functionality to login using gmail account. Now, Google maps on the device has saved home and office address of the user. Is it possible to get this data without user having to input it? 回答1: You can geocode the addresses with Google Geocoding API . Depending of what you want, you can get an XML or JSON response by calling http://maps.google.com/maps/api/geocode/json?address=ADRESS HERE Where all the spaces of the address must be replaced by +

问题 I have an application here that has a feature of showing a POI on the map. It's only one POI and it is only drawn when it's actually within the visible screen area. It works perfectly for a while but if I play around zooming in and out and dragging, it will eventually crash. According to Logcat, the reason is always an OutOfMemory error. At first, I thought it was a bug on the Google Maps API. After some researching and seeing some Romain Guy posts, I was kind of convinced that I had done
