Question

Can the v2 and v3 Google Maps API coexist on the same page?

Answer 1

+1 A:

I don't think the two APIs are meant to co-exist on the same page. I tried a very basic example, which happens to have the same problem as yours. Tested in Chrome 5.0 and Firefox 3.6.6 (both for Mac):

<!DOCTYPE html>
<html> 
<head> 
  <meta http-equiv="content-type" content="text/html; charset=UTF-8" /> 
  <title>Google Maps v2 and v3 on same page</title> 
  <script src="http://maps.google.com/maps?file=api&amp;amp;v=2&amp;amp;sensor=false"
          type="text/javascript"></script>
  <script src="http://maps.google.com/maps/api/js?sensor=false" 
          type="text/javascript"></script>
</head> 
<body> 
  <div id="map_v3" style="width: 500px; height: 400px;"></div>
  <div id="map_v2" style="width: 500px; height: 400px; margin-top: 50px;"></div>

  <script type="text/javascript">

    var map3 = new google.maps.Map(document.getElementById('map_v3'), {
      zoom: 6,
      center: new google.maps.LatLng(-41.00, 174.00),
      mapTypeId: google.maps.MapTypeId.ROADMAP
    });

    var map2 =  new GMap2(document.getElementById('map_v2'));
    map2.addControl(new GLargeMapControl3D());
    map2.setCenter(new GLatLng(-41.00, 174.00), 6);
  </script>

</body>
</html>

The weird thing is they do co-exist if you interact with the v2 map first.

Yes, noticed that :)

I was a the Sydney Google Dev-Fest and asked a Googler this question. I can confirm they are not designed to exist on the same page.

After emailing support about it one of the developers replied, "Using the same namespace and sharing a good bunch of class, methods and constant ames, V2 and V3 APIs are not designed to run together in the same page." And then in a follow up email "Indeed you can run both versions together, it is possible and works fairlywell, considering it's not designed to do so." So I guess the answer is it works sort of ;)

@RueTheWhirled: Interesting. Was this response on the public api groups?

Daniel Vassallo 2010-07-20 00:32:37

@Daniel Vassallo nah, I did report a bug about in the api groups but the emails were from google enterprise support

Gonna mark this as the answer although; if it was somehow possible to simulate interacting with the v2 map in the same way as if the user had then it might be possible to overcome the particular issue I've described. I think it might have to do with v2 using an array to store events where v3 is using an object but its in the internals of the API so hard to fix. And having said that there's probably still other bugs with having both v2 and v3 on same page
