MVC后台创建Json(List)前台接受并循环读取实例

  ---------------------------后台-------------------

  

复制代码 代码如下:

  [HttpPost]

  public JsonResult CheckStock(IEnumerable<pvIdsCount> pvIds)

  {

  var resultList = new List<pvIdsCount>();

  if (pvIds != null)

  {

  foreach (var pvIdsCount in pvIds)

  {

  var pvId = pvIdsCount.pvId;

  var count = pvIdsCount.count;

  var stock = _productService.GetProductVariantById(pvId).StockQuantity;

  if (stock - count < 0)

  {

  var pvIdC=new pvIdsCount();

  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; }

  }

  ---------------------------前台-------------------

  

复制代码 代码如下:

  AJAX

  success: function (data) {

  if (data == "success") {

  }

  } else {

  $.each(data.resultList, function (index, value) {

  $("#Item_PVId_" + value.pvId).html("This Product's Stock Not Enough.Stock is " + value.count);

  });

  }

  }
