Center/Set Zoom of Map to cover all visible Markers?

I am setting multiple markers on my map and I can set statically the zoom levels and the center but what I want is, to cover all the markers and zoom as much as possible hav

Answer 1

The size of array must be greater than zero. Οtherwise you will have unexpected results.

function zoomeExtends(){
  var bounds = new google.maps.LatLngBounds();
  if (markers.length>0) { 
      for (var i = 0; i < markers.length; i++) {
         bounds.extend(markers[i].getPosition());
        }    
        myMap.fitBounds(bounds);
    }
}
