1.请在sql server 中建一数据库 name:house 在house中运行下列脚本
if exists (select * from sysobjects where id = object_id(N"[dbo].[City]") and OBJECTPROPERTY(id, N"IsUserTable") = 1)
drop table [dbo].[City]
GO
if exists (select * from sysobjects where id = object_id(N"[dbo].[Area]") and OBJECTPROPERTY(id, N"IsUserTable") = 1)
drop table [dbo].[Area]
GO
CREATE TABLE [dbo].[City] (
[id] [int] IDENTITY (1, 1) NOT NULL ,
[name] [nvarchar] (10) NULL
) ON [PRIMARY]
GO
CREATE TABLE [dbo].[Area] (
[id] [int] IDENTITY (1, 1) NOT NULL ,
[CityId] [int] NULL ,
[name] [nvarchar] (20) NULL
) ON [PRIMARY]
GO
INSERT INTO City (id,name) Values(1,"广州")
INSERT INTO City (id,name) Values(2,"上海")
INSERT INTO City (id,name) Values(3,"北京")
INSERT INTO Area (id,CityId,name) Values(1,1,"天河")
INSERT INTO Area (id,CityId,name) Values(2,1,"白云")
INSERT INTO Area (id,CityId,name) Values(3,2,"虹口")
INSERT INTO Area (id,CityId,name) Values(4,2,"宝山")
INSERT INTO Area (id,CityId,name) Values(5,2,"静安")
INSERT INTO Area (id,CityId,name) Values(6,3,"海淀")
INSERT INTO Area (id,CityId,name) Values(7,3,"朝阳")
2.建立文件
建立文件CityData.asp
<%@ LANGUAGE=VBSCRIPT %>
<% RSDispatch %>
<script RUNAT=SERVER Language=javascript>


function Description()
{
this.GetAreaAsArray = DoGetData;
}
public_description = new Description();
function DoGetData(cityId)
{
var sql,rst,strText,conn,i,j
conn = new ActiveXObject("ADODB.Connection");
conn.ConnectionString = connstr;
