1.获得系统时间:
<%=now()%>

2.取得来访用的IP:
<%=request.serverVariables("remote_host")%>

3.获得浏览器版本:
<script> window.document.write("版本："+navigator.appName+navigator.appVersion+" browser.") </script>

4.去掉IE滚动条:
<body scroll="no"> <body style="overflow-y:hidden">

5.进入网站,跳出广告:
<script language="javascript">  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.向上滚动代码:
<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="javascript">  </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="javascript"> 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 value="images/yj16d.swf"><param name=quality value=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) <% '::: BMP, GIF, JPG and PNG :::
