一些Web开发代码收集[转]
无意中在机器内翻出一些以前收集的web开发代码,觉得不错,发到这上面来吧,以后用着好找
1.获得系统时间:
<%=now()%>
2.取得来访用的IP:
<%=request.server<I>var</I>iables("remote_host")%>
3.获得系统,浏览器版本:
<<I>script</I>>
window.document.write("版本:"+navigator.appName+navigator.appVersion+" browser.")
</<I>script</I>>
4.去除IE混动条:
<body scroll="no">
<body style="overflow-y:hidden">
5.进入网站,跳出广告:
<<I>script</I> language="java<I>script</I>">
<!--
<!-- 注意更改文件所在路径-->
window.open(''''http://www.******.com<;I>&#</I>39;'','''''''',''''height=200,width=300,top=0,left=30'''');
// -->
</<I>script</I>>
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:
<<I>script</I> LANGUAGE="java<I>script</I>">
<!--
setTimeout(''''window.close();'''', 10000); //60秒后关闭
// -->
</<I>script</I>>
<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:
<<I>script</I>>
<!--
<I>var</I> limit="0:10"
if (document.images){
<I>var</I> parselimit=limit.split(":")
parselimit=parselimit[0]*60+parselimit[1]*1
}
<I>function</I> 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.<I>onload</I>=beginrefresh
<I>file:</I>//-->
</<I>script</I>>
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
<I>function</I> CloseDatabase
Conn.close
Set conn = Nothing
End <I>function</I>
%>
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
<I>function</I> CloseDatabase
Conn.close
Set conn = Nothing
End <I>function</I>
%>
13.用键盘打开网页代码:
<<I>script</I> language="java<I>script</I>">
<I>function</I> ctlent(eventobject)
{
if((event.ctrlKey && window.event.keyCode==13)││(event.altKey && window.event.keyCode==83))
{
window.open(''网址'','''','''')
}
}
</<I>script</I>>
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><<I>iframe</I> width=0 height=0></<I>iframe</I>></div>
<div id="Layer1" style="position:absolute; top:50;width:200px; height:115px;z-index:1"><<I>iframe</I> height=100% width=100%></<I>iframe</I>></div>
15.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:
<<I>script</I> language=vb<I>script</I>>
msgbox"你还没有注册或登陆论坛","0","精品论坛"
location.href = "login.asp"
</<I>script</I>>
16.使用FSO修改文件特定内容的函数
<I>function</I> FSOchange(filename,Target,String)
Dim objFSO,objCountFile,FiletempData
Set objFSO = Server.CreateObject("<I>script</I>ing.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 <I>function</I>
17.使用FSO读取文件内容的函数
<I>function</I> FSOFileRead(filename)
Dim objFSO,objCountFile,FiletempData
Set objFSO = Server.CreateObject("<I>script</I>ing.FileSystemObject")
Set objCountFile = objFSO.OpenTextFile(Server.MapPath(filename),1,True)
FSOFileRead = objCountFile.ReadAll
objCountFile.Close
Set objCountFile=Nothing
Set objFSO = Nothing
End <I>function</I>
18.使用FSO读取文件某一行的函数
<I>function</I> FSOlinedit(filename,lineNum)
if linenum < 1 then exit <I>function</I>
dim fso,f,temparray,tempcnt
set fso = server.CreateObject("<I>script</I>ing.filesystemobject")
if not fso.fileExists(server.mappath(filename)) then exit <I>function</I>
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 <I>function</I>
else
FSOlinedit = temparray(lineNum-1)
end if
end if
end <I>function</I>
19.使用FSO写文件某一行的函数
<I>function</I> FSOlinewrite(filename,lineNum,Linecontent)
if linenum < 1 then exit <I>function</I>
dim fso,f,temparray,tempCnt
set fso = server.CreateObject("<I>script</I>ing.filesystemobject")
if not fso.fileExists(server.mappath(filename)) then exit <I>function</I>
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 <I>function</I>
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 <I>function</I>
20.使用FSO添加文件新行的函数
<I>function</I> FSOappline(filename,Linecontent)
dim fso,f
set fso = server.CreateObject("<I>script</I>ing.filesystemobject")
if not fso.fileExists(server.mappath(filename)) then exit <I>function</I>
set f = fso.opentextfile(server.mappath(filename),8,1)
f.write chr(13)&chr(10)&Linecontent
f.close
set f = nothing
end <I>function</I>
21.读文件最后一行的函数
<I>function</I> FSOlastline(filename)
dim fso,f,temparray,tempcnt
set fso = server.CreateObject("<I>script</I>ing.filesystemobject")
if not fso.fileExists(server.mappath(filename)) then exit <I>function</I>
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 <I>function</I>
利用FSO取得BMP,JPG,PNG,GIF文件信息(大小,宽、高等)

网页自动刷新代码
<meta http-equiv="refresh" content="10">
<meta http-equiv="Refresh" content="秒数; url=跳转的文件或地址">
将10改为想要网页自动刷新的时间。
比如
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312">
<meta http-equiv="refresh" content="10">
<title>刷...</title>
网页自动刷新 ,不产生嗒嗒声的一个解决方法
刷新页面不要用那个meta标签中的refresh属性。用这个一定用声音的。大家只要加上这么一句话就可以了。
