I figured how to 'put' various markers but the console will throw me an error: " Uncaught InvalidValueError: setCenter: not a LatLng or LatLngLiteral object ". I think it's because the var created in the loop is not exactly the object needed but instead a string, though this confuses me, I don't know if I'm right. I'd appreciate it a lot if anyone could set me in the right path. Thanks in advance. This is my code: (By the way, the array I'm

Lets say the direction line goes from Budapest to Warsaw. I want to get all latitude and longitude on that line. But I don't find any build in function or workaround for this. I don't copy code here as the tutorial works for me , I can start from that. (Of course it isn't a good idea to make lot of waypoints.) I've seen this question . It isn't solution for my problem, as its not for API3 Thanks in advance.

I'd like to put a legend in the corner of the map window that tells the user what each color means. The Google Maps API includes a GScreenOverlay class that has the behavior that I want, but it only lets you specify an image to use as an overlay, and I'd prefer to use a DIV with text in it. What's the easiest way to position a

Some time I was trying to apply a colored plot aroud the route in fixed length. But I cant get a nice rounded corners and my lack of math is making me a lot of truble. Now I got this And the code var r = []; var bla = result.routes[0].overview_path; for(i in result.routes[0].overview_path) { r.push(new google.maps.LatLng(bla[i].lat()+z, bla[i].lng()-z)); } bla.reverse(); for(x in bla) { r.push(new google.maps.LatLng(bla[x].lat()-z, bla[x]

Using the built in geocode object results in massively blurred results (lots of postcodes returning just a general area). Are there any free UK postcode geocoding services I can plug into via JavaScript? 回答1: Edit: To be clearer this uses the local search in google search api, not the google maps api to do the geocoding which is much more accurate. The best way is to use Google Search Api. If you get an api key and get it all setup: http://code.google.com/apis/ajaxsearch/

I need to be able to, using either V2 OR V3 (preferably 3), create paths which ignore buildings in a sense. I was trying to create even a kml file to draw out all of the paths myself, and then find some way to turn them on/off as needed. For example. The user wants to go from point A to point B. Between these points is a number of buildings. The user physically CAN walk through these buildings(it's a campus). I want to show them that on the map. This way you don't have to do a loop-de

If I use a general event listener for zoom_changed, I can't tell if it is a user-generated event or a zoom change caused by something like fitBounds(). Looking for the best way to do this. I've tried the following things, none of which seem to work: 1) Looked for event information on zoom_changed. There appears to be none. 2) Add listeners for mouseover and mouseout that let me set a flag to see if the user is in the

How can I strip the latitude and the longitude from the "event.latLng"? It is returning a point() , but I need only the lat alone and the long for itself. I cant get this to work. 回答1: According to the API for MouseEvents , event.latLng contains a LatLng , not a Point . If this is the case then you can use the lat() and lng() methods to get the values separately. If event.latLng is actually a Point

I tried the following but it doesn't work. Anyone have advice? //create array to store a set of location var collection = new Array(); //a set of locations stored in array collection[0] = new google.maps.LatLng(13.742167701649997, 100.50721049308777); collection[1] = new google.maps.LatLng(13.74428, 100.5404525); collection[2] = new google.maps.LatLng(13.744108, 100.543098); var pointMarkerImage = new Array(
