.Net 文本框?qū)崿F(xiàn)內(nèi)容提示的實(shí)例代碼(仿Google、Baidu)

這篇文章主要介紹了.Net 文本框?qū)崿F(xiàn)內(nèi)容提示的實(shí)例代碼,需要的朋友可以參考下

1.Demo下載：

文本框?qū)崿F(xiàn)內(nèi)容提示(仿Google、Baidu).rar

2.創(chuàng)建數(shù)據(jù)庫(kù)、表（我用的sqlserver2008數(shù)據(jù)庫(kù)）

復(fù)制代碼 代碼如下:

CREATE TABLE Ceshi
(
   id VARCHAR(50) PRIMARY KEY NOT NULL,
   cname VARCHAR(30)
)
GO
INSERT INTO Ceshi
SELECT NEWID(),'jack1' UNION
SELECT NEWID(),'jack2' UNION
SELECT NEWID(),'jack3' UNION
SELECT NEWID(),'jack4' UNION
SELECT NEWID(),'jack5' UNION
SELECT NEWID(),'peter1' UNION
SELECT NEWID(),'peter2' UNION
SELECT NEWID(),'peter3' UNION
SELECT NEWID(),'peter4' UNION
SELECT NEWID(),'peter5'
go

3.創(chuàng)建自定義函數(shù)

復(fù)制代碼 代碼如下:

create function [dbo].[f_GetPy](@str nvarchar(4000))
returns nvarchar(4000)
as
begin
declare @strlen int,@re nvarchar(4000)
declare @t table(chr nchar(1) collate Chinese_PRC_CI_AS,letter nchar(1))
insert into @t(chr,letter)
select '吖 ', 'A ' union all select '八 ', 'B ' union all
   select '嚓 ', 'C ' union all select '咑 ', 'D ' union all
   select '妸 ', 'E ' union all select '發(fā) ', 'F ' union all
   select '旮 ', 'G ' union all select '鉿 ', 'H ' union all
   select '丌 ', 'J ' union all select '咔 ', 'K ' union all
   select '垃 ', 'L ' union all select '嘸 ', 'M ' union all
   select '拏 ', 'N ' union all select '噢 ', 'O ' union all
   select '妑 ', 'P ' union all select '七 ', 'Q ' union all
   select '呥 ', 'R ' union all select '仨 ', 'S ' union all
   select '他 ', 'T ' union all select '屲 ', 'W ' union all
   select '夕 ', 'X ' union all select '丫 ', 'Y ' union all
   select '帀 ', 'Z '
   select @strlen=len(@str),@re= ' '
   while @strlen> 0
   begin
     select top 1 @re=letter+@re,@strlen=@strlen-1
     from @t a where chr <=substring(@str,@strlen,1)
     order by chr desc
     if @@rowcount=0
     select @re=substring(@str,@strlen,1)+@re,@strlen=@strlen-1
   end
   return(@re)
end
GO

4.asp.net前臺(tái)頁(yè)面（需要添加2個(gè)引用：AjaxControlToolkit.dll，AutoCompleteExtra.dll）

復(fù)制代碼 代碼如下:

5.后臺(tái)頁(yè)面

復(fù)制代碼 代碼如下:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using Oceansoft.Net.Bll;

namespace WebApplication1

    {
        protected void Page_Load(object sender, EventArgs e)
        {

        }

        [System.Web.Services.WebMethodAttribute(), System.Web.Script.Services.ScriptMethodAttribute()]
        public static string[][] GetCompanyNameList(string prefixText, int count, string contextKey)
        {
            //獲取自動(dòng)完成的選項(xiàng)數(shù)據(jù)
            List<string[]> list = new List<string[]>();
            List<string> nameList = new List<string>();
            List<string> idList = new List<string>();
            CeshiManage ceshimanage = new CeshiManage();

            ceshimanage.GetTopUserName(count, prefixText.ToUpper(), out idList, out nameList);
            for (int i = 0; i < nameList.Count; i++)
            {
                string[] Respuesta = new string[2];
                Respuesta[0] = nameList[i];
                Respuesta[1] = idList[i];
                list.Add(Respuesta);
            }
            return list.ToArray();
        }
    }
}
