Django - Custom Geolocation

You can implement this with HTML5 and Google Maps APIs.

• Using HTML5 Geolocation API , you will get the coordinates of the user's location.
• Using the coordinates and the Google Maps API for reverse geocoding , you will get the user's full address.

An example implementation -

function checkLocation() {
    //geolocation API options
    var options =  {
        maximumAge: 5 * 60 * 1000,
        enableHighAccuracy: true,
        timeout: 20000};
    //success getting the geolocation
    function success(ppos) {
        lat = ppos.coords.latitude;
        lng = ppos.coords.longitude;
        codeLatLng(lat, lng);
    }
    //error when getting the geolocation 
    function error(err) {
        var errorMessage = "Error:";
        switch(err.code) {
            case err.TIMEOUT:
            errorMessage = 'Error: Attempts to retrieve location timed out.';
            break;
            case err.POSITION_UNAVAILABLE:
            errorMessage = "Error: Your browser doesn't know where you are.";
            break;
            case err.PERMISSION_DENIED:
            errorMessage = 'Error: You have to give us permission!';
            break;
            case err.UNKNOWN_ERROR:
            errorMessage = 'Error: Unknown error returned.';
            break;
            default:
            errorMessage = 'Error: ' + err + ' ' + err.code;
        }
    }
    if (navigator.geolocation) {
        navigator.geolocation.getCurrentPosition(success, error, options);
    }
}

function codeLatLng(lat, lng) {
    var lat = parseFloat(lat);
    var lng = parseFloat(lng);
    var latlng = new google.maps.LatLng(lat, lng);
    geocoder.geocode({'latLng': latlng}, function(results, status) {
        if (status == google.maps.GeocoderStatus.OK) {
            if (results[1]) {
                return results[1].formatted_address;
            } else {
                alert('No results found');
            }
        } else {
            alert('Geocoder failed due to: ' + status);
        }
    });
}

      

        
        
        
      

    

I think this solution might give you the country and city, but I don't think it will give you the zip code.
