Hi, I managed to make an ajax call. But the form is always invalid. IT is like the captcha field passed to the view is always empty.

I have the following class view taken from documentation:

            return HttpResponse(json.dumps(to_json_response), content_type='application/json')

            return HttpResponse(json.dumps(to_json_response), content_type='application/json')
        else:
            return HttpResponse("test2", content_type='application/json')


and the following ajax call from template:

    <script type="text/javascript">
        function captcha() {
            $.ajax({
                type: "POST", 
                url: "../captcha",
                contentType: "application/json",
                data: {},
                dataType: "json",
                success: function(data) {
                    alert("success");
                  },
                error: function(data) {
                    alert("not OK");
                  }

                });
        }
    </script>


<input type="button" id="button" onclick="captcha()" value="OK"/>
