Question

这是我的剃刀代码的一部分

@using (Ajax.BeginForm("DeleteBeacon", "Beacons", new { beaconId = Model.ID, instId = Model.InstID, pageNo = (int)ViewBag.pageNumber }, new AjaxOptions { LoadingElementId = "imgloaderIndex", OnSuccess = "OnSuccessDelete(data)", OnFailure = "OnFailureDelete(data)" }))

这是我的控制器代码：

public ActionResult DeleteBeacon(UserProfile userInfo, long beaconId, long instId, int? pageNo)
    {
        bool status = false;
        int pNumber = (pageNo ?? 1);          
        ViewBag.pageNumber = pNumber;
        try
        {
            status = blBeacon.DeleteBeacon(beaconId, userInfo.UserID, userInfo.SessionToken, null);
            if (status)
            {
                return Json(new { status = "success", pageNumber = pageNo, instId = Convert.ToInt64(TempData["InstituteId"]) });
            }
            else
            {
                return Json(new { status = "failure" });
            }
        }
        catch (Exception exp)
        {
            LogUtil.Error("BeaconsController\\DeleteBeacon:\n" + exp.Message);
            return Json(new { status = "failure", message = exp.Message });
        }

    }

它在本地服务器上工作正常，但在生产服务器上托管时，我在尝试删除时遇到错误。错误是

POST https://portal.example.com/Beacons/DeleteBeacon?beaconId=36&instId=9594&pageNo=2 500 (Internal Server Error) 
Uncaught ReferenceError: data is not defined

更新：我挖得更深一点，它显示data is not defined in OnFailureDelete(data)这意味着POST调用失败但是为什么??

任何人都可以建议可能出错的地方

我确定您不需要在OnSuccess和OnFailure电话中传递data。

... { LoadingElementId = "imgloaderIndex", OnSuccess = "OnSuccessDelete", OnFailure = "OnFailureDeleteenter code here"

那些应该声明data的JavaScript，例如：。

function OnSuccessDelete(data) { //... }

我无法复制您的问题。但是，这是我的工作示例代码，希望它可能对您有用：

<强>控制器

[HttpPost]
public ActionResult DeleteBeacon(object beaconid, object instid, int pageno)
{
    return Json(new { result = "Hello" });
}

查看

@using (Ajax.BeginForm("DeleteBeacon", "Home", new { beaconId = 1, instId = 2, pageNo = 3 }, new AjaxOptions { HttpMethod = "POST", OnSuccess = "OnSuccessDelete", OnFailure = "OnFailureDelete" })) { <input type="submit" value="Click Me"/> } <script type="text/javascript"> function OnSuccessDelete(data) { console.log(data); } function OnFailureDelete(data) { console.log("Failure " + data); } </script>

要呼叫OnFailureDelete()，您必须将代码的响应状态设置为200以外的其他内容，例如

[HttpPost] public ActionResult DeleteBeacon(object beaconid, object instid, int pageno) { Response.StatusCode = 500; return Json(new { result = "Hello" }); }
