在不刷新页面的情况下调用远程asp脚本

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;
            conn.ConnectionTimeout = 30;
            conn.Open();
            sql  = "Select name,id from area where cityid=´" + cityId + "´";
            rst  = new ActiveXObject("ADODB.Recordset");
            rst.CursorLocation = 3;

            rst.Open(sql,conn);
            i = 0;
            j = 0;
        strText = new Array();

            if (rst.RecordCount >= 1)
            {
              for(var i=0;i<rst.RecordCount;++i)
              {
              strText[j++] = rst.Fields("name").Value;
              strText[j++] = rst.Fields("id").Value;
              rst.movenext();
                }
              }
              else
            {
              strText[j++] = "没有";
              strText[j++] = 1;
              }
            rst.close();
            conn.close();
            return strText;
        }
</SCRIPT>

建立文件jsconn.asp

<SCRIPT RUNAT=SERVER Language=javascript>
var connstr = "driver={SQL Server}; server=202.0.0.108;uid=sa;pwd=;database=house";
</SCRIPT>

建立文件pub.asp
<%

  Function OpenOrGet_Database
    Dim SessionName, conn
    const connstr = "driver={SQL Server}; server=202.0.0.108;uid=sa;pwd=;database=house"
    SessionName = "House"
    If Not IsObject(Session(SessionName)) Then
      Set conn = Server.CreateObject("ADODB.Connection")
      conn.Open connstr
      Set Session(SessionName) = conn
    End If
    Set OpenOrGet_Database = Session(SessionName)
  End Function

%>

建立文件sql_pub.asp
<%

  ´取出城市资料
  Function SelectCity()
    Dim Conn, Sql, Rs, ArrCity, TmpArr(1,0)
    Set Conn = OpenOrGet_Database
    Set Rs = Server.CreateObject("ADODB.Recordset")
    Sql = "Select distinct name,id from City"
    Rs.Open Sql,Conn,3
    if Rs.Eof then
      TmpArr(0,0) = "城市"
      TmpArr(1,0) = 0
      Rs.Close
      SelectCity = TmpArr
    else
      ArrCity = RS.GetRows()
      Rs.Close
      SelectCity = ArrCity
    end if
  End Function

  ´根据传来的CityId取出相应的地区资料
  Function SelectArea(CityId)
    Dim Conn, Sql, Rs, ArrArea, TmpArr(1,0)
    Set Conn = OpenOrGet_Database
    Set Rs = Server.CreateObject("ADODB.Recordset")
    Sql    =" Select name,id from Area where CityId=" & CityId & " order by id "
    Rs.Open Sql,Conn,3
    if Rs.Eof then
      TmpArr(0,0) = "地区"
      TmpArr(1,0) = 0
      Rs.Close
      SelectArea = TmpArr
    else
      ArrArea = RS.GetRows()
      Rs.Close
      SelectArea = ArrArea
    end if
  End Function

建立文件test.asp
