!!!JS文件操作的问题,高手看一下怎么回事!!!

要读取服务器的文件,你应该用ASP来实现.demo.asp<% @Language="JavaScript" %>
<%
var fso, f1, ts, s;
var ForReading = 1;
fso = new ActiveXObject("Scripting.FileSystemObject");
ts = fso.OpenTextFile("c:\\testfile.txt", ForReading);
s = ts.ReadLine();
Response.Write("File contents = '" + s + "'");
%>
