function (data) {

});
</script>
</body>
</html>
2、新建一个ashx/Ajaxauto.ashx ，提取sql数据库中的数据
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Services;
using System.Data;
using System.Collections;
using System.Web.Services.Protocols;
using System.Data.SqlClient;
using System.Configuration;
using System.Text;
using System.Runtime.Serialization.Json;
using System.Runtime.Serialization;
public void ProcessRequest(HttpContext context)
{
// 查询的参数名称默认为term
string fac = context.Request.QueryString["term"];
string selectStr = "";
selectStr = @"SELECT FACTORY,CONVERT(varchar(10),monthend,120)as monthend, CONVERT(varchar(10),[Month End],120) as [Month End], CONVERT(varchar(10),invdate,120) as invdate, invno, INVexcel.order_no, pihead_dm.pi_no as PI,pihead_dm.band as BRAND, goods, producttype, num_chu, num_moneychu, tax,notaxmoney, USDmoney, taxmoney, filename, update_by, update_date FROM INVexcel left outer join pihead_dm on INVexcel.order_no=pihead_dm.pi_no Where filename = '" + fname + "'";
context.Response.ContentType = "text/plain";
string key = selectStr.ToString().Trim();
Autojquery exsql = new Autojquery();
List<JqueryUIinv> Autolist = new List<JqueryUIinv>();
Autolist = exsql.GetJquerylistinv(key);
System.Web.Script.Serialization.JavaScriptSerializer js = new System.Web.Script.Serialization.JavaScriptSerializer();
string s = js.Serialize(Autolist);
context.Response.Write(js.Serialize(Autolist));
public bool IsReusable {
get {
return false;
}
}
3、新建一个Autojquery.cs
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Services;
using System.Data;
using System.Collections;
using System.Web.Services.Protocols;
using System.Data.SqlClient;
using System.Configuration;
using System.Text;
using System.Runtime.Serialization.Json;
using System.Runtime.Serialization;
/// <summary>
///Autojquery 的摘要说明
/// </summary>
public class Autojquery
{
public List<JqueryUIinv> GetJquerylistinv(string selkey)
{
//string sql = "select * from puller where ddacode like N'%" + selkey + "%'";
string sql = selkey;
List<JqueryUIinv> modellist = new List<JqueryUIinv>();
DataTable dt = SqlHelper.GetTable(sql);
if (dt.Rows.Count > 0)
{
for (int i = 0; i < dt.Rows.Count; i++)
{
JqueryUIinv model = new JqueryUIinv();
LoadEntityDataDetailinv(dt.Rows[i], model);
modellist.Add(model);
}
}
return modellist;
}
private void LoadEntityDataDetailinv(DataRow dr, JqueryUIinv model)
{
model.monthend = dr["monthend"].ToString();
model.invdate = dr["invdate"].ToString();
model.invno = dr["invno"].ToString();
model.order_no = dr["order_no"].ToString();
model.PI = dr["PI"].ToString();
model.BRAND = dr["BRAND"].ToString();
model.goods = dr["goods"].ToString();
model.num_chu = dr["num_chu"].ToString();
model.num_moneychu = dr["num_moneychu"].ToString();
model.tax = dr["tax"].ToString();
model.notaxmoney = dr["notaxmoney"].ToString();
model.USDmoney = dr["USDmoney"].ToString();
model.taxmoney = dr["taxmoney"].ToString();
}
}
4、新建一个JqueryUI.cs //定义所需字段
using System;
using System.Data;
using System.Configuration;
using System.Linq;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.HtmlControls;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Xml.Linq;
public class JqueryUIinv
{
public string monthend { set; get; }
public string invdate { set; get; }
public string invno { set; get; }
public string order_no { set; get; }
public string PI { set; get; }
public string BRAND { set; get; }
public string goods { set; get; }
public string num_chu { set; get; }
public string num_moneychu { set; get; }
public string tax { set; get; }
public string notaxmoney { set; get; }
public string USDmoney { set; get; }
public string taxmoney { set; get; }
}
5、定于一个SqlHelper.cs
