     ]),
     showCancelButton: true,

     beforeClose: (action, instance, done) => {

       instance.confirmButtonText = '执行中...';
       setTimeout(() => {
        done();
        setTimeout(() => {
         instance.confirmButtonLoading = false;
        }, 300);
       }, 3000);
      } else {
       done();
      }
     }
