Answer 1

$(document).ready(function(){
    $('#error').hide();
    $('#submit').click(function(){
        var name = $("#name").val();
        if (name == "") {
            $("#error").show("slow");
            return false;
        }
        var pass = $("#password").val();
        if (pass == "") {
            $("#error").show("slow");
            return false;
        }
        $.ajax({
            url: "/ajax/",
            type: "POST",
            data: { 
                'name': name, 
                'csrfmiddlewaretoken': '{{csrf_token}}'
            }, 
            contentType: "application/json;charset=utf-8",
            dataType: "json",
            success: function(data) { 
                alert(data);
            },
            error: function(ts) { 
                alert(ts);
            }
        });
    });
});


def lat_ajax(request):
    if request.POST:
        name = request.POST['name']
        return HttpResponse(name)
    else :
        return render_to_response('ajax_test.html',locals())
