Hi,

Please refer below script to get latitude and longitude.

I referred below article

Google Maps API V3: Get Latitude and Longitude of a location from Address using JavaScript

JavaScript

function GetLocation(Address) {
    var geocoder = new google.maps.Geocoder();
    var address = Address;
    var location = [];
    geocoder.geocode({ 'address': address }, function (results, status) {
        if (status == google.maps.GeocoderStatus.OK) {
            var latitude = results[0].geometry.location.lat();
            var longitude = results[0].geometry.location.lng();
            location.push(latitude);
            location.push(longitude);
        } else {
            alert("Request failed.")
        }
    });
    return location;
};

I hope this will help you out.
