         1.获得系统时间:  <DIV class=code>  <%=now()%> </DIV>   2.取得来访用的IP:  <DIV class=code>  <%=request.serverVariables("remote_host")%> </DIV>   3.获得系统,浏览器版本:    <DIV class=code>  <script>    window.document.write("版本:"+navigator.appName+navigator.appVersion+" browser.")    </script></DIV>   4.去除IE混动条:     <DIV class=code>  <body scroll="no">    或   <body style="overflow-y:hidden"> </DIV>   5.进入网站,跳出广告:     <DIV class=code>  <script language="javascript">    <!--    <!-- 注意更改文件所在路径-->    window.open('http://www.XXXXXX.com','','height=200,width=300,top=0,left=30');    // -->    </script></DIV>   6.随机数:    <DIV class=code>  <%randomize%>    <%=(int(rnd()*n)+1)%></DIV>   N为可改变数    7.向上混动代码:    <DIV class=code><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> </DIV>   8.自动关闭网页:  <DIV class=code>  <script LANGUAGE="javascript">    <!--    setTimeout('window.close();', 10000); //60秒后关闭    // -->    </script>    <p align="center">本页10秒后自动关闭,请注意刷新页面</p> </DIV>   9.随机背景音乐:  <DIV class=code>  <%randomize%>    <bgsound src="mids/<%=(int(rnd()*60)+1)%>.mid" loop="-1"> </DIV>   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:  <DIV class=code>  <script>    <!--       var limit="0:10"       if (document.images){    var parselimit=limit.split(":")    parselimit=parselimit[0]*60+parselimit[1]*1    }    function beginrefresh(){    if (!document.images)    return    if (parselimit==1)    window.location.reload()    else{    parselimit-=1    curmin=Math.floor(parselimit/60)    cursec=parselimit%60    if (curmin!=0)    curtime=curmin+"分"+cursec+"秒后重刷本页!"    else    curtime=cursec+"秒后重刷本页!"    window.status=curtime    setTimeout("beginrefresh()",1000)    }    }       window.onload=beginrefresh    file://-->    </script> </DIV>      11.ACCESS数据库连接:  <DIV class=code>  <%    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    %> </DIV>   12.SQL数据库连接:  <DIV class=code>  <%    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    %> </DIV>   13.用键盘打开网页代码:     <DIV class=code>  <script language="javascript">    function ctlent(eventobject)    {    if((event.ctrlKey && window.event.keyCode==13)||(event.altKey && window.event.keyCode==83))    {    window.open('网址','','')    }    }    </script></DIV>      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 class=code>  <div z-Index:2><object xxx></object></div> # 前面    <div z-Index:1><object xxx></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> </DIV>   15.动网FLASH广告代码:  <DIV class=code><object classid="clsid:D27CDB6E-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> </DIV>   msgbox"你还没有注册或登陆论坛","0","精品论坛"   location.href = "login.asp"       16.使用FSO修改文件特定内容的函数 <DIV class=code>  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</DIV>   17.使用FSO读取文件内容的函数 <DIV class=code>  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</DIV>   18.使用FSO读取文件某一行的函数 <DIV class=code>  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</DIV>   19.使用FSO写文件某一行的函数 <DIV class=code>  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</DIV>   20.使用FSO添加文件新行的函数 <DIV class=code>  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</DIV>   21.读文件最后一行的函数 <DIV class=code>  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</DIV>
