            //            notifier.notify("Hello World!"); 
            notifier.notify({
                message: "正在提交...",
                position: 'center',
                fadeInMs: 0,
                fadeOutMs: 0,
                ms: 6000,
                modal: true,
                loader: true
               }); 
}
