      $(document).ready(function() { 
        $('#AddToCard').click(function() { 
        var ProductID = $('#txtproductID').val(); 
        var Quantity = $('#txtQuantity').val(); 
        var NetAmt = $('#txtNetAmt').val(); 
        var ProName = $('#txtPN').val(); 
        alert("ID="+ProductID+"QTY=" + Quantity+"NETAMT=" + NetAmt+"Name=" + ProName); 
        $.ajax({ 
         type: "POST", 
         url: '../Home/AddOrderItem', 
         data: { productCode: ProductID, quantity: Quantity, NAMT: NetAmt, PName: ProName }, 

         success: function (data) { 
          if (data) { 
     //      alert("Added To your Card"); 
          } 
         } 
        }); 
       }); 


      }); 
     </script> 

我cotroller是

 public void AddOrderItem(Int64 productCode, int quantity, decimal NAMT, string PName) 
      { 
       //adds an item to the current order 
       OrderDO order = (OrderDO)Session["Order"]; 
       decimal TotAmt = quantity * NAMT; 
       order.Items.Add(new OrderItem(productCode, quantity,NAMT,PName,TotAmt)); 
       Session["Order"] = order; 
       } 

Answer 1

從控制器返回結果，查看您應該返回JSON對象。

public ActionResult AddOrderItem(Int64 productCode, int quantity, decimal NAMT, string PName) 
{ 
    //adds an item to the current order 
    OrderDO order = (OrderDO)Session["Order"]; 
    decimal TotAmt = quantity * NAMT; 
    order.Items.Add(new OrderItem(productCode, quantity,NAMT,PName,TotAmt)); 
    Session["Order"] = order; 

    return Json(order, JsonRequestBehavior.AllowGet); 
}
