规范的前台JS操作返回

$.post(‘@Url.Action("BatchCancel")‘, postData, function (res) {
   if (res.flag) {
       ZTLayer.showTips(‘@T("admin.order.cancelorder.ok")‘, 6, 3000, function () {  window.location.reload();   });
   }else {
　　　　if (res.url)
       {     window.location.href = res.url;
             return;
       }
       ZTLayer.showTips(res.msg||‘@T("admin.common.cancelordererror")‘);
     }
  });

if (!_workContext.CurrentCustomer.IsRegistered())
    return Json(new { flag = false, url = Url.RouteUrl("Login") });  //不能直接Redirt到Login页，否则前台JS捕捉到的是个Html页面,无法进行判断
 
if (!string.IsNullOrEmpty(orderIds))
{
    ResultModel result = _orderProcessingService.CancelOrder(orderList);
　　 return Json(new { flag = result.Flag == 1, msg = result.Message }); 
}else
{
 　　return Json(new { flag = false, msg = _localizationService.GetResource("admin.common.cancelordererror") }); //统一返回格式
}
