ASP.NET MVC使用EasyUI的datagrid多选提交保存教程

需要实现EasyUI的datagrid组件加入选择checkbox列，并提交后台批量添加的功能，页面代码如下：


代码如下:

<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('保存失败！');
}
}, '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>
<th field="ck" checkbox="true"></th>
<th field="Identifier" hidden="true" width="0" editor="text">Id</th>
<th field="Goods_Name" width="100" editor="{type:'validatebox',options:{required:true}}">商品名称</th>
<th field="Chemistry" width="100" editor="{type:'validatebox',options:{required:true}}">化学指标</th>
<th field="Physical" width="100" editor="{type:'validatebox',options:{required:true}}">物理指标</th>
<th field="Partner_Name" width="50" editor="{type:'validatebox',options:{required:true}}">合作状态</th>
</tr>
</thead>
</table>
<div id="tlb_selectgoods_search">
商品名称：<input name="keywords" id="selectgoods-keywords" class="easyui-searchbox" /><a href="#" class="easyui-linkbutton" iconCls="icon-save" plain="true" onclick="javascript:saveSelectGoods()">保存</a>
</div>
</div>

ASP.NET MVC的Controller代码如下：


代码如下:

/// <summary>
/// 多选商品添加
/// </summary>
/// <param name="supplier">供货商ID</param>
/// <returns></returns>
public ActionResult SelectGoods(string supplier)
{
ViewData["supplier"] = supplier;
return View();
}
/// <summary>
/// 保存批量添加的产品信息
/// </summary>
/// <param name="checks">选中的商品ID</param>
/// <param name="supplier">供货商名称</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;
//拼装xml
String ids=Communion.StringHelper.BuildXmlID(checks);
goods.Goods_ID = -1;//标示批量插入
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;
}
}

存储过程利用xml变量对传入的xml类型的ID集合进行批量添加保存到数据库中，存储过程代码如下：


代码如下:

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
--批量插入商品
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
