Laravel 4 AJAX CSRF Token Mismatch (with _token) -

i'm attempting simple (soft) delete on model customized implementation of frozennode/administrator package. whenever hit route via ajax, application throws tokenmismatchexception.

i've tried both cookie , file drivers set in session config.

i have confirmed _token being submitted ajax request. commenting csrf filter out altogether allows me delete record. i'm using out-of-the-box csrf filter.

i'm using excellent sweet alert plugin, though doesn't appear related.

routes.php:

//csrf protection in forms route::group(array('before' => 'csrf'), function() {      //delete item     route::post('{model}/{id}/delete', array(         'as' => 'admin_delete_item',         'uses' => 'frozennode\administrator\admincontroller@delete'     ));  ... 

blade template:

<a href="" class="btn btn-danger" id="delete-item-button" data-token="{{ csrf_token()}} ">     <i class="fa fa-trash"></i>     <span>         &nbsp;delete     </span> </a> 

javascript:

excuse hellishness $.post what's relevant.

$('#delete-item-button').on('click', function (e) { e.preventdefault();  var token = $(this).data('token');  swal({     title: "delete record?",     text: "there's no undo!",     type: "warning",     showcancelbutton: true,     confirmbuttoncolor: "#dd6b55",     confirmbuttontext: "yes, delete it!",     closeonconfirm: false }, function () {     $.post(         window.location.pathname + "/delete",         {"_token" : token},         function(){             swal({                 title: "deleted!",                 text: "the record has been deleted.",                 type: "success"             },                 function () {                     window.location.href = 'http://www.example.com'                 })},         "json"         );     }); }); 

any or guidance greatly appreciated.

thanks!
