1.获得系统时间:
<%=now()%>
2.取得来访用的IP:
<%=request.serverVariables(remote_host)%>
3.获得系统,浏览器版本:
<script>
window.document.write(版本：+navigator.appName+navigator.appVersion+ browser.)
</script>
4.去除IE混动条:
<body scroll=no>
<body style=overflow-y:hidden>
5.进入网站,跳出广告:
<script language=＆#106avascript>

window.open(''http://www.XXXXXX.com'','''',''height=200,width=300,top=0,left=30'');
// -->
</script>
6.随机数:
<%randomize%>
<%=(int(rnd()*n)+1)%>
N为可改变数
7.向上混动代码:
<marquee direction=up scrolldelay=200 style=font-size: 9pt; color: #FF0000;
line-height: 150%; font-style:italic; font-weight:bold scrollamount=2 width=206
height=207 bgcolor=#FFFF00>hhhhhhhhhhhhhhhhhhh</marquee>
8.自动关闭网页:
<script LANGUAGE=＆#106avascript>

</script>
<p align=center>本页10秒后自动关闭,请注意刷新页面</p>
9.随机背景音乐:
<%randomize%>
<bgsound src=mids/<%=(int(rnd()*60)+1)%>.mid loop=-1>　

可以修改数字，限制调用个数，我这里是６０个．
10.自动刷新本页面:
<script>

</script>
11.ACCESS数据库连接:
<%
option explicit
dim startime,endtime,conn,connstr,db
startime=timer()
'更改数据库名字
db=data/dvBBS5.mdb
Set conn = Server.CreateObject(ADODB.Connection)
connstr=Provider=Microsoft.Jet.OLEDB.4.0;Data Source= & Server.MapPath(db)
'如果你的服务器采用较老版本Access驱动，请用下面连接方法
'connstr=driver={Microsoft Access Driver (*.mdb)};dbq= & Server.MapPath(db)
conn.Open connstr
function CloseDatabase
Conn.close
Set conn = Nothing
End Function
%>
12.SQL数据库连接:
<%
option explicit
dim startime,endtime,conn,connstr,db
startime=timer()
connstr=driver={SQL Server};server=HUDENQ-N11T33NB;uid=sa;pwd=xsfeihu;database=dvbbs
Set conn = Server.CreateObject(ADODB.Connection)
conn.Open connstr
function CloseDatabase
Conn.close
Set conn = Nothing
End Function
%>
13.用键盘打开网页代码:
<script language=＆#106avascript>
function ctlent(eventobject)
{
if((event.ctrlKey && window.event.keyCode==13)||(event.altKey && window.event.keyCode==83))
{
window.open('网址','','')
}
}
</script>　

这里是Ctrl+Enter和Alt+S的代码自己查下键盘的ASCII码再换就行
14.让层不被控件复盖代码:
<div z-Index:2><object ***></object></div> ＃前面
<div z-Index:1><object ***></object></div> ＃后面
<div id=Layer2 style=position:absolute; top:40;width:400px; height:95px;z-index:2><table height=100% width=100% bgcolor=#ff0000><tr><td height=100% width=100%></td></tr></table><iframe width=0 height=0></iframe></div>
<div id=Layer1 style=position:absolute; top:50;width:200px; height:115px;z-index:1><iframe height=100% width=100%></iframe></div>
15.动网FLASH广告代码:
<object classid=clsid27CDB6E-AE6D-11cf-96B8-444553540000 codebase=http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=5,0,0,0 width=468 height=60><param name=movie ＆#118alue=images/yj16d.swf><param name=quality ＆#118alue=high><embed src=images/dvbanner.swf quality=high pluginspage=http://www.macromedia.com/shockwave/download/index.cgi?P1_Prod_Version=ShockwaveFlash;;; type=application/x-shockwave-flash width=468 height=60></embed></object>
16.VBS弹出窗口小代码:
<script language=vbscript>
msgbox你还没有注册或登陆论坛,0,精品论坛
location.href = login.asp
</script>
16.使用FSO修改文件特定内容的函数
function FSOchange(filename,Target,String)
Dim objFSO,objCountFile,FiletempData
Set objFSO = Server.CreateObject(Scripting.FileSystemObject)
Set objCountFile = objFSO.OpenTextFile(Server.MapPath(filename),1,True)
FiletempData = objCountFile.ReadAll
objCountFile.Close
FiletempData=Replace(FiletempData,Target,String)
Set objCountFile=objFSO.CreateTextFile(Server.MapPath(filename),True)
objCountFile.Write FiletempData
objCountFile.Close
Set objCountFile=Nothing
Set objFSO = Nothing
End Function
17.使用FSO读取文件内容的函数
function FSOFileRead(filename)
Dim objFSO,objCountFile,FiletempData
Set objFSO = Server.CreateObject(Scripting.FileSystemObject)
Set objCountFile = objFSO.OpenTextFile(Server.MapPath(filename),1,True)
FSOFileRead = objCountFile.ReadAll
objCountFile.Close
Set objCountFile=Nothing
Set objFSO = Nothing
End Function
18.使用FSO读取文件某一行的函数
function FSOlinedit(filename,lineNum)
if linenum < 1 then exit function
dim fso,f,temparray,tempcnt
set fso = server.CreateObject(scripting.filesystemobject)
if not fso.fileExists(server.mappath(filename)) then exit function
set f = fso.opentextfile(server.mappath(filename),1)
if not f.AtEndofStream then
tempcnt = f.readall
f.close
set f = nothing
temparray = split(tempcnt,chr(13)&chr(10))
if lineNum>ubound(temparray)+1 then
exit function
else
FSOlinedit = temparray(lineNum-1)
end if
end if
end function
19.使用FSO写文件某一行的函数
function FSOlinewrite(filename,lineNum,Linecontent)
if linenum < 1 then exit function
dim fso,f,temparray,tempCnt
set fso = server.CreateObject(scripting.filesystemobject)
if not fso.fileExists(server.mappath(filename)) then exit function
set f = fso.opentextfile(server.mappath(filename),1)
if not f.AtEndofStream then
tempcnt = f.readall
f.close
temparray = split(tempcnt,chr(13)&chr(10))
if lineNum>ubound(temparray)+1 then
exit function
else
temparray(lineNum-1) = lineContent
end if
tempcnt = join(temparray,chr(13)&chr(10))
set f = fso.createtextfile(server.mappath(filename),true)
f.write tempcnt
end if
f.close
set f = nothing
end function
20.使用FSO添加文件新行的函数
function FSOappline(filename,Linecontent)
dim fso,f
set fso = server.CreateObject(scripting.filesystemobject)
if not fso.fileExists(server.mappath(filename)) then exit function
set f = fso.opentextfile(server.mappath(filename),8,1)
f.write chr(13)&chr(10)&Linecontent
f.close
set f = nothing
end function
21.读文件最后一行的函数
function FSOlastline(filename)
dim fso,f,temparray,tempcnt
set fso = server.CreateObject(scripting.filesystemobject)
if not fso.fileExists(server.mappath(filename)) then exit function
set f = fso.opentextfile(server.mappath(filename),1)
if not f.AtEndofStream then
tempcnt = f.readall
f.close
set f = nothing
temparray = split(tempcnt,chr(13)&chr(10))
FSOlastline = temparray(ubound(temparray))
end if
end function
利用FSO取得BMP，JPG，PNG，GIF文件信息(大小，宽、高等)
