<div id="service" style="BEHAVIOR:url(webservice.htc)"></div>

3.编写JavaScript，实现对WebService的引用：

function window_onload()
public class Service1 : System.Web.Services.WebService
<HTML>
<HEAD>
<title>jsWebServices</title>
<meta name="GENERATOR" Content="Microsoft Visual Studio .NET 7.1">
<meta name="CODE_LANGUAGE" Content="C#">
<meta name="vs_defaultClientScript" content="JavaScript">
<meta name="vs_targetSchema" content="http://schemas.microsoft.com/intellisense/ie5">
</HEAD>
<body MS_POSITIONING="GridLayout" onload="return window_onload()">
<div id="service" style="BEHAVIOR:url(webservice.htc)"></div>
<form id="Form1" method="post" runat="server">
<SELECT id="select_province" onchange="province_onchange();" style="Z-INDEX: 101; LEFT: 8px; WIDTH: 128px; POSITION: absolute; TOP: 16px">
<OPTION selected></OPTION>
</SELECT><SELECT id="select_city" onchange="city_onchange();" style="Z-INDEX: 102; LEFT: 160px; WIDTH: 128px; POSITION: absolute; TOP: 16px">
<OPTION selected></OPTION>
</SELECT><SELECT id="select_area" style="Z-INDEX: 103; LEFT: 304px; WIDTH: 128px; POSITION: absolute; TOP: 16px">
<OPTION selected></OPTION>
</SELECT>
</form>
</body>
</HTML>
6.引用webservicers
7.数据库脚本

if exists (select * from dbo.sysobjects where id = object_id(N'[dbo].[area]') and OBJECTPROPERTY(id, N'IsUserTable') = 1)
drop table [dbo].[area]
GO

if exists (select * from dbo.sysobjects where id = object_id(N'[dbo].[province]') and OBJECTPROPERTY(id, N'IsUserTable') = 1)
drop table [dbo].[province]
GO

if exists (select * from dbo.sysobjects where id = object_id(N'[dbo].[city]') and OBJECTPROPERTY(id, N'IsUserTable') = 1)
drop table [dbo].[city]
GO

CREATE TABLE [dbo].[area] (
[id] [int] NOT NULL ,
[areaID] [nvarchar] (50) COLLATE Chinese_PRC_CI_AS NULL ,
[area] [nvarchar] (60) COLLATE Chinese_PRC_CI_AS NULL ,
[father] [nvarchar] (6) COLLATE Chinese_PRC_CI_AS NULL
) ON [PRIMARY]
GO

CREATE TABLE [dbo].[province] (
[id] [int] NOT NULL ,
[provinceID] [nvarchar] (6) COLLATE Chinese_PRC_CI_AS NULL ,
[province] [nvarchar] (40) COLLATE Chinese_PRC_CI_AS NULL
) ON [PRIMARY]
GO

CREATE TABLE [dbo].[city] (
[id] [int] NOT NULL ,
[cityID] [nvarchar] (6) COLLATE Chinese_PRC_CI_AS NULL ,
[city] [nvarchar] (50) COLLATE Chinese_PRC_CI_AS NULL ,
[father] [nvarchar] (6) COLLATE Chinese_PRC_CI_AS NULL
) ON [PRIMARY]
GO
