Question

我正在尝试在MVC 4视图上有多个提交按钮，然后根据单击的按钮选择要在控制器中执行的操作。但是，控制器无法识别单击了哪个按钮并始终显示为null。

我做错了什么？

//View
@using (Html.BeginForm())
{
<button type = "submit" name = "btn" value = "save_new" id = "SaveNew" > Save & amp; New </button>
<button type = "submit" name = "btn" value = "save_close" id = "SaveClose" > Save & amp; Close </button>
}

//Controller
public ActionResult PortalAccountMapping(PortalAccountMappingModel model, string btn)

    {
        if (btn == "save_new")
        {
            // the form was submitted using the Save&New button
        }
        else if (btn == "save_close")
        {
            // the form was submitted using the Save&Close button
        }
        else
        {
            UpdateModel(model.Grid.UpdateParams);
           return Json(model.GetRows());
        }

        return View();
    }

btn值始终为空。

Answer 1

Message = Client.PostAsync(CompleteURL, Content).Result

这是我使用的

控制器看不到单击了哪个按钮
