Question

can I set automatic zoom level in google map ?

Answer 1

A:

When you instantiate a google maps object using: new google.maps.Map(domElement, options)

You can can use options to set (among other things) the zoom level.

The default zoom level can be set using { zoom: 14 } for example.

After you create you google maps object, you can change the zoom level using setZoom()

var myMap = new google.maps.Map(
    document.getElementById('map-canvas'), 
    { zoom : 14 } 
);

myMap.setZoom(12);

This is not what the user asked. He was asking for an *automatic* way to do this.

            type="text/javascript"></script>
    <script type="text/javascript">

    function initialize() {
      if (GBrowserIsCompatible()) {
        var map = new GMap2(document.getElementById("map_canvas"));
        map.setCenter(new GLatLng(37.4419, -122.1419), 13);
        map.setUIToDefault();
      }
    }

    </script>
  </head>
  <body onload="initialize()" onunload="GUnload()">
    <div id="map_canvas" style="width: 500px; height: 300px"></div>
  </body>
</html>

The map.setCenter() function can be used to set the zoom level i.e map.setCenter(GLatLng coordinate, zoom level)

Answer 3

+2 A:

See: http://stackoverflow.com/questions/2265055/how-to-get-google-maps-api-to-set-the-correct-zoom-level-for-a-country

In summary, you use a Geocoder object to getLocations by a query string (", "). Then use a returned PlaceMarker object to define a LatLngBounds object. Use the LatLngBounds object as a paramter for getBoundsZoomLevel to set the zoom level.
