callback

The callback function takes one parameter which is the result of the action asserted and depends on the request.

• marker will send a google.maps.Marker
• circle will send a google.maps.Circle
• getlatlng will send a google.maps.LatLng
• ...

In this example, you can see one another important feature of gmap3, in callback $(this) is equivalent to the current jQuery element which is there $("#test")

$("#test").gmap3({
  getlatlng:{
    address:  "Paris, France",
    callback: function(results){
      if ( !results ) return;
      $(this).gmap3({
        marker:{
          latLng:results[0].geometry.location
        }
      });
    }
  }
});
