Get status code of current request

Question

I have a request made by Jqueryfiledownload that when error occurs the server returns different types of status. I need to act on the client according to these errors. Other than jquery ajax I can’t get by fileDownload receive the current status of the request. I would like to know if there is any way via javascript get this status. Remembering that the call will continue to be made by fileDownload.

$.fileDownload(url)
    .done(function () {                     
        jSuccess("com sucesso!", "Sucesso");
    })
    .fail(function () {
        var erro = //quero pegar o status aqui

 });
