$.ajax({
        type: postType,
        url: url,
        data: postData || '',
        xhrFields: {

        crossDomain: true,
        success: function () {
            successCallback.apply(scope || this, arguments);
        },
        failureCallback: function () {
            failureCallback.apply(scope || this, arguments);
