转自我本良人 原文 jquery autocomplete实现读取sql数据库自动补全TextBox
项目需要这样子一个功能，其他部门提的意见，只好去实现了哦，搞了好久才弄出来，分享一下。
1.前台页面
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default3.aspx.cs" Inherits="Default3" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head id="Head1" runat="server"> <title></title> <script src="jquery-1.4.1-vsdoc.js" type="text/javascript"></script> <script src="jquery.autocomplete.js" type="text/javascript"></script> <link href="jquery.autocomplete.css" type="text/css" rel="stylesheet" /> <script language="javascript" type="text/javascript"> $(document).ready((function () { $("#txtUser").autocomplete("GetCode.aspx"); } )); </script> </head> <body> <form id="form1" runat="server"> <div> 用户名： <asp:TextBox ID="txtUser" runat="server"></asp:TextBox> </div> </form> </body> </html>
2.GetCode.aspx
前台为空
后台代码：
using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; using System.Data; using System.Data.SqlClient; public partial class GetCode : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { if (Request.QueryString["q"] != null) { string key = Request.Params["q"].ToString(); string result = ""; SqlHelp sql = new SqlHelp(); string str = "select top 15 CustomCode from tCustomList where CustomCode like '" + key + "%'"; SqlDataReader dr = sql.ExecuteReader(str); while (dr.Read()) { result += dr["CustomCode"].ToString() + "\n"; } dr.Dispose(); sql.SqlClose(); if (result == "") result = "not exists"; Response.Write(result); } } }
