ASP.NET MVC saves the tutorial using EasyUI's datagrid multiple option submission

The datagrid component of EasyUI needs to be added to select checkbox column and submit the function of background batch addition. The page code is as follows:

 
<script language="javascript" type="text/javascript"> 
$(function() { 
//searchbox 
$('#selectgoods-keywords').searchbox({ 
searcher: function(val, name) { 
searchInfo(val); 
} 
}); 
//datagrid 
$('#selectgoods-grid').datagrid({ 
url: '/Goods/List', 
pageNumber: 1, 
pageSize: 20, 
pageList: [20, 40, 60, 80, 100] 
}); 
//form 
}); 
function searchInfo(val){ 
// var keytype=$('#keyType').combobox('getValue'); 
var keytype = 'Goods_Name'; 
var keywords = val; 
$('#selectgoods-grid').datagrid('reload', { keytype: keytype, keywords: keywords }); 
} 
function saveSelectGoods() { 
var ids = []; 
var rows = $('#selectgoods-grid').datagrid('getSelections'); 
for (var i = 0; i < rows.length; i++) { 
ids.push(rows[i].Identifier); 
} 
var selectsupplier = '<%=ViewData["supplier"] %>'; 
$.post('/SupplierGoods/SaveSelect', { supplier: selectsupplier, checks: ids.join(',') }, function(data) { 
if (data) { 
$('#goodslist-grid').datagrid('reload'); 
$('#goodsInfo-window').window('close'); 
} else { 
alert(' Save failed! '); 
} 
}, 'json'); 
} 
</script> 
<div style="width:100%; height:100%"> 
<table id="selectgoods-grid" class="easyui-datagrid" fit="true" toolbar="#tlb_selectgoods_search" pagination="true" 
rownumbers="true" fitColumns="true" idField="Identifier"> 
<thead> 
<tr>

</tr>

</table> 
<div id="tlb_selectgoods_search">

</div> 

The Controller code for ASP.NET MVC is as follows:

 
/// <summary> 
///  Select more items to add  
/// </summary> 
/// <param name="supplier"> The supplier ID</param> 
/// <returns></returns> 
public ActionResult SelectGoods(string supplier) 
{ 
ViewData["supplier"] = supplier; 
return View(); 
} 
/// <summary> 
///  Save the batch added product information  
/// </summary> 
/// <param name="checks"> Selected goods ID</param> 
/// <param name="supplier"> Supplier name </param> 
/// <returns></returns> 
public JsonResult SaveSelect(string checks, string supplier) 
{ 
JsonResult result = new JsonResult(); 
result.Data = false; 
try 
{ 
if (String.IsNullOrEmpty(supplier)) 
return result; 
SupplierGoods goods = new SupplierGoods(); 
goods.Identifier = 0; 
// assemble xml 
String ids=Communion.StringHelper.BuildXmlID(checks); 
goods.Goods_ID = -1;// Marked batch insert  
goods.Note = ids; 
goods.Month_Output = Convert.ToDouble(String.IsNullOrEmpty(this.ReadFromRequest("Month_Output")) ? "0" : this.ReadFromRequest("Month_Output")); 
goods.Supplier_ID = Convert.ToInt32(supplier); 
goods.Create_Date = DateTime.Now; 
goods.Customers = this.ReadFromRequest("Customers"); 
goods.Equipment = this.ReadFromRequest("Equipment"); 
goods.Detail_Params = this.ReadFromRequest("Detail_Params"); 
goods.IsDefault = Convert.ToInt32(String.IsNullOrEmpty(this.ReadFromRequest("IsDefault")) ? "0" : this.ReadFromRequest("IsDefault")); 
Business business = new BusinessLogic(); 
int id = business.Save<SupplierGoods>(goods); 
if (goods.Identifier == 0) 
{ 
goods.Identifier = id; 
} 
result.Data = true; 
return result; 
} 
catch (Exception e) 
{ 
return result; 
} 
} 

The stored procedure makes use of xml variable to batch add and save the incoming ID collection of xml type to the database. The stored procedure code is as follows:

 
ALTER PROCEDURE [dbo].[View_SupplierGoodsCreate] 
@Identifier int, 
@Supplier_ID int, 
@Goods_ID int, 
@isDefault int, 
@Create_Date datetime, 
@Month_Output float(8), 
@Goods_Name nvarchar(400)=NULL, 
@Physical nvarchar(400)=NULL, 
@Chemistry nvarchar(400)=NULL, 
@Customers nvarchar(400)=NULL, 
@Equipment nvarchar(400)=NULL, 
@Note nvarchar(MAX)=NULL, 
@Detail_Params nvarchar(400)=NULL 
AS 
IF @Goods_ID=-1 
BEGIN 
-- Bulk insert  
DECLARE @xml xml 
SET @xml=@Note 
INSERT INTO Supplier_Goods(Supplier_ID,Goods_ID,Create_Date,Month_Output,Customers,Equipment,Note,isdefault,Detail_Params) 
SELECT @Supplier_ID,identifier,@Create_Date,0,null,null,null,0,null 
FROM Base_Goods 
WHERE 
Identifier in (Select 
T.ID.value('.', 'int') As ID 
From 
@xml.nodes('/XML/ID') as T(ID)) and Identifier not in (select goods_id from Supplier_Goods where Supplier_ID=@Supplier_ID) 
SET @Identifier=@Goods_ID 
END
