you need new view receives data ajax call. should work:
from flask import request @app.route('/location', methods=['post']) def location(): latitude = request.json.get('latitude') longitude = request.json.get('longitude') then on client side:
$.ajax({ type: 'post', url: '/location', data: json.stringify({'latitude': latitude, 'longitude': longitude}, null, '\t'), contenttype: 'application/json;charset=utf-8' });
