[HttpPost]

public JsonResult CheckStock(IEnumerable<pvIdsCount> pvIds)

{

var resultList = new List<pvIdsCount>();

if (pvIds != null)

{

foreach (var pvIdsCount in pvIds)

{

if (stock - count < 0)

{

pvIdC.pvId = pvId;

pvIdC.count = stock;

resultList.Add(pvIdC);

}

}

if (resultList.Count > 0)

{

return Json(new { resultList }); //Json() ---MVC的JSON 方法会自动把List<T> IEnumerable<T>转换为 Json Array<T>

}

else

{

return Json("success");

}

}

return null;

}

public class pvIdsCount

{

public int pvId { set; get; }

public int count { set; get; }

}
