有三个文件：
Rs.asp ：在服务器端进行引用，来完成服务器端的初始化工作
Rs.Htm ：其实它是一个JavaScript 脚本文件，使用完成请求分析数据
Rsproxy.class ：是一个Java 小程序，就是通过它来完成客户端与服务端的通信
-------- 服务端文件 Server.asp----
<%@ LANGUAGE=VBSCRIPT %>
<!--#include file="_ScriptLibrary/rs.asp"--> //必须要包含这个文件
<% RSDispatch %> //对 Remote Scripting 进行初始化,必须第一个调用
<SCRIPT Language=JavaScript RUNAT=SERVER>
function Description(){
this.myFunction = myFunction; //暴露myFunction函数
}
public_description = new Description();
function myFunction(strInput, numLength) //在这里实现这个myFunction 函数
{
var objConn = Server.CreateObject("ADODB.Connection");
objConn.Open("dsn=pubs;uid=sa;pwd=;Network=DBMSSOCN");
var objRS = Server.CreateObject("ADODB.Recordset");
objRS.MaxRecords = numLength;
objRS.Open("SELECT au_lname, au_fname FROM Authors Where (au_lname + ', ' + au_fname) >= '" + strInput + "' ORDER BY au_lname,au_fname", objConn, 0, 3);
var tmpMsg = new String;
tmpMsg.value = "";
while (!objRS.EOF){
tmpMsg.value = tmpMsg.value + objRS("au_lname") + ", " + objRS("au_fname") + ":";
objRS.MoveNext();
}
objConn.Close();
return tmpMsg.value;
