Saving Json data from javascript

[Shazia Nusrat]

Hi,

Below is the code for Javascript from Django template Google Maps API. I need to be able to save this in my Django models with JSON response. I am new user so an example will be really a great help.

Precisely I need to be able to save coordinates like latitude and longitude and then convert it to an address.

Thanks 

var map, infoWindow;
      function initMap() {
        map = new google.maps.Map(document.getElementById('map'), {
          center: {lat: -34.397, lng: 150.644},
          zoom: 6
        });
        infoWindow = new google.maps.InfoWindow;

        // Try HTML5 geolocation.
        if (navigator.geolocation) {
          navigator.geolocation.getCurrentPosition(function(position) {
            var pos = {
              lat: position.coords.latitude,
              lng: position.coords.longitude
            };

            infoWindow.setPosition(pos);
            infoWindow.setContent('Location found.');
            infoWindow.open(map);
            map.setCenter(pos);
          }, function() {
            handleLocationError(true, infoWindow, map.getCenter());
          });
        } else {
          // Browser doesn't support Geolocation
          handleLocationError(false, infoWindow, map.getCenter());
        }
      }

      function handleLocationError(browserHasGeolocation, infoWindow, pos) {
        infoWindow.setPosition(pos);
        infoWindow.setContent(browserHasGeolocation ?
                              'Error: The Geolocation service failed.' :
                              'Error: Your browser doesn\'t support geolocation.');
        infoWindow.open(map);
      }

Hi Shazia,

You can make a XHR (Ajax) request in javascript to send the data to a django callback.

HTH,

Can you please show me any example about the structure of code I've provided?

Thanks

I'm not really sure what you meant here. Anyways, there's plenty of good JS frameworks like jQuery to allow you to write Ajax functions to send a JSON array for post-processing in Django.
