Using navigator.geolocation.getCurrentPosition(); synchronously

I have this function that is trying to return the latitude and longitude as a string when called. However when i call it with an alert it returns undefined. But when I alert the data.coords.latitude/longitude it gives me the correct values. Any help is greatly appreciated.

function GetLocation() {
    var jsonLocation;
    navigator.geolocation.getCurrentPosition(function (data) {
        jsonLocation = data.coords.latitude+','+data.coords.longitude;
    });
    return String(jsonLocation);
}
alert(GetLocation());

getCurrentPosition() expects a callback:

function getLocation(callback) {
    navigator.geolocation.getCurrentPosition(function (data) {
        var jsonLocation = data.coords.latitude+','+data.coords.longitude;
        callback(jsonLocation);
    });
}

getLocation(alert);

I changed up the code so the callback would alert the information when the getCurrentPosition returns

function RequestLocation() {
            navigator.geolocation.getCurrentPosition(function (data) {
                SendLocation(String(data.coords.latitude + ',' + data.coords.longitude));
            });
        }
        function SendLocation(cords)
        {
            alert(cords);
        }

        RequestLocation();
