asp.net mvc - Ajax post throws A required anti-forgery token was not supplied or was invalid -

i'm trying secure ajax posts using anti-forgery mechanism.

first i've added antiforgerytoken helper method call view

@html.antiforgerytoken() 

and adjusted jquery post call

var values = $(this).serialize() + "&__requestverificationtoken=" + $("input[name='__requestverificationtoken']").val();  $.post(url, values)     .success(page.submitsuccess)     .error(page.submiterror)     .complete(page.submitcomplete); 

and of course decorated action method validateantiforgerytoken

[httppost] [validateantiforgerytoken] public actionresult create(projectcreatecommand command) {     .... } 

but after submiting form throws a required anti-forgery token not supplied or invalid error.

i've deleted token cookie , i've restarted browser.

am missing ?

if use $(form).serialize(); serialize input tags, can $.post jquery method. try this:

$("#you_form").submit(function (e) {     e.preventdefault();     $.ajax({        type: 'post',        url: $(this).attr("action"), // url action attribute, route setted html.beginform()        data: $(this).serialize(), // serialize input tags form        success: page.submitsuccess;      }); }); 

there no problem using @html.antiforgerytoken(), serialize method add together.
