Answer 1

The marker.setMap method expects the argument to be a google.maps.Map object. This is not one of those:

var map= Ext.getCmp('mapCanvas');

Answer 2

var map is a HTML element you need an instance of the google.maps.Map Object

var map = google.maps.Map(document.querySelector("#mapCanvas"),{
      center: new google.maps.LatLng(24.027872, -104.655278),
      zoom: 12
    });

then....

var marker= new google.maps.Marker({
  position: new google.maps.LatLng(25,118),
  map: map
    });

Answer 3

mapCanvas is Ext map component which holds the map instance.

var map= Ext.getCmp('mapCanvas');
console.dir(map);
var marker= new google.maps.Marker({
                    position: new google.maps.LatLng(25,118),
              });
marker.setMap(map.getMap());

Answer 4

Try this:

    marker = new google.maps.Marker({
                position : position,
                setMap : map
            }); 

It worked for me!

Answer 5

Try this:

var  latlngbounds = new google.maps.LatLngBounds(),
     position = new google.maps.LatLng(25,118),
     marker = new google.maps.Marker({
            position : position,
            map : map
        }); 

latlngbounds.extend(position);

map.fitBounds(latlngbounds);

Here map is the rendered google.map.Map instance

Answer 6

You can add the marker to the map directly by using the marker's setMap() method, as shown in the example below:

var myLatlng = new google.maps.LatLng(-25.363882,131.044922);
var mapOptions = {
  zoom: 4,
  center: myLatlng
}
var map = new google.maps.Map(document.getElementById("map"), mapOptions);

var marker = new google.maps.Marker({
    position: myLatlng,
    title:"Hello World!"
});

// To add the marker to the map, call setMap();
marker.setMap(map);
