How to get user's geolocation?

Question

On many sites I saw printed out my current city where I am (eg \"Hello to Berlin.\"). How they do that? What everything is needed for that? I guess the main part is here jav

Correc syntax would be :

navigator.geolocation.getCurrentPosition(successCallBack, failureCallBack);

Use :

    navigator.geolocation.getCurrentPosition(
        function(position){
            var latitude  = position.coords.latitude;
            var longitude = position.coords.longitude;
            console.log("Latitude : "+latitude+" Longitude : "+longitude);
        },
        function(){
            alert("Geo Location not supported");
        }
    );
