為什么在將控制權返回給請求時，代碼總是 go 到非假部分？

Question

我有這個調用，它調用 controller 中的一個動作，並期望 object 命名數據中的真或假。

$("#btnReview").click(function () {
    var data = {
        'id': '1',
        'recordID': selectedInspectionId, 'RoleRemarks': $("#CNGInspectionReport_RoleRemarks").val()
    };

    $.post('/CNGInspectionReport/ChangeStatus', data, function (data) {

        if (data == false) {

            alert('Something went wrong');
        }
        else {
            alert('Record reviewed successfully. Kindly review the further records, if any.');
           
        }
    });
});

和

public ActionResult ChangeStatus(int id, int recordID, string RoleRemarks, string Role = "") // Later, this should be converted to an object instead of parameters
{
    try
    {

        using (UnitOfWork uwork = new UnitOfWork())
        {
            CNGInspectionReportDAL = new CNGInspectionReportDAL();

            User user = (User)Session["User"];

            CNGInspectionReport CNGInspectionReport = uwork.CNGInspectionReportRepository.GetByID(recordID);

            CNGInspectionReport.CNGInspectionReportID = recordID;

            bool statusCrossOffice = false;

            if (id == 1) //Reviewed
            {
                if(user.Office.Trim() != CNGInspectionReport.StationName.Trim())
                {

                    return Json(new { data = statusCrossOffice, message = "Sorry, this record belongs to another office/station and can only be reviewed by the user of the same station/office" });
                }

                CNGInspectionReport.RoleRemarks = RoleRemarks;

                CNGInspectionReport.CheckedBy = user.UserID;
                CNGInspectionReport.CheckedByName = user.UserName;
                CNGInspectionReport.Status = (byte)id;
                CNGInspectionReport.ReviewDate = DateTime.Now;

            }
            return Json(new { data = status, message = "Success" });
        }
    }
    catch (Exception ex)
    {
        ViewBag.Error = ex.Message;
        return Json(new { data = false, message = ex.Message });
    }
}

但問題是當返回到 Ajax 調用時，它仍然會轉到 else 塊。 為什么？ 我已經清楚地返回了數據中的 Fase，但它仍然進入了不是 FALSE 的 else 部分。

您應該評估返回的 object 的數據屬性

if (data.data == false) {
         alert('Something went wrong');
}

這是因為data返回值是 object 而不是 boolean。 您可以自己檢查該值：

$.post('/CNGInspectionReport/ChangeStatus', data, function (data) {
         alert(JSON.stringify(data));
         // etc
