---------------------------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); 
});
