on Firefox, only on firefox it will popup and give you a warning This web page is being redirected to a new location. Would you like to resend the for form you have typed to the new location.

I got no form , i use javascript to extract values from textbox

I checked on firebug it says
PUT /admin/submit-scan/ 301 moved permanently
PUT submit-scan 302 Found

My JS

function submitGoods(){

    var registeredNo = $('input[name=registeredno]').val();

    var weight = $('input[name=weight]').val();

        $.ajax({

            type: 'PUT',

            url: '/admin/submit-scan/',

            data: {

                registeredNo: registeredNo,

                weight: weight,

                _token: csrfToken

            },

            dataType: 'json'

        }).done(function(data){



                data = $.parseJSON(data);

            });



}

My Route

Route::put('submit-scan', 'ControllersAdminDashboardController@putUpdateSubmitScan');

My controller

 public function putUpdateSubmitScan()

    {

        if (Request::ajax())

        {

            return Response::json(array('success' => 1, 'data' => test));

        }

    }

Any idea what went wrong?
