i have defined map variable, latlng , marker. right lat , lang values when alert(..).

thanks

why converting string.

the constructor documentation

latlng(lat:number, lng:number, nowrap?:boolean)

change

latlng = new google.maps.latlng(json.stringify(place.lat), json.stringify(place.lng));

to

latlng = new google.maps.latlng(place.lat,place.lng);
