asp初学者常用的一些代码 _intlineno = objtextstream.line-优快云博客

本文汇总了多种实用的网页设计和脚本技巧，包括获取系统时间、访客IP、浏览器版本等基本信息的方法，以及实现网页自动关闭、刷新、弹窗等功能的代码示例。

摘要生成于 C知道，由 DeepSeek-R1 满血版支持，前往体验 >

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="javascript">

***********(''http://www.******.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="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>
<!--

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)
}
}

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="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000"
codebase="http://download.macromedia.com/pub/shockwave/cabs/flash****lash.cab#version=5,0,0,0"
width="468" height="60"><param name=movie value="images/yj16d****">
<param name=quality value=high>
<embed src="images/dvbanner****" 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
