【注意】整理了一些初学者常用的代码(更新)
1.获得系统时间:
2.取得来访用的IP:
3.获得系统,浏览器版本:
window.document.write("版本:"+navigator.appName+navigator.appVersion+" browser.")
4.去除IE混动条:
5.进入网站,跳出广告:
window.open(''
http://www.roc3000.com/lnbbs/pic/url.gif
http://www.XXXXXX.com'','''',''height=200,width=300,top=0,left=30'');
// -->
6.随机数:
N为可改变数
7.向上混动代码:
hhhhhhhhhhhhhhhhhhh
8.自动关闭网页:
本页10秒后自动关闭,请注意刷新页面
9.随机背景音乐:
.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: 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 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>
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 24.点击返回上页代码:
24.点击刷新代码:
24.点击刷新代码2:
25.弹出警告框代码:
26.状态栏信息
27.背景色变换
function BgButton(){
if (document.bgColor=='#00ffff')
{document.bgColor='#ffffff';}
else{document.bgColor='#00ffff';}
}
28.点击打开新窗口
<form>
<p><input TYPE="button" value="打开新窗口" onCLICK="NewWindow()"></p>
</form>
<script language="javascript"><!--
function NewWindow(){window.open(http://www.roc3000.com/lnbbs/pic/url.gif "http://www.mcmx.com";,"","height=240,width=340,status=no,location=no,toolbar=no,directories=no,menubar=no");}
// --></script></body> 29.分页代码:
<%''本程序文件名为:Pages.asp%>
<%''包含ADO常量表文件adovbs.inc,可从"\Program Files\Common Files\System\ADO"目录下拷贝%>
<!--#Include File="adovbs.inc"-->
<%''*建立数据库连接,这里是Oracle8.05数据库
Set conn=Server.CreateObject("ADODB.Connection")
conn.Open "Provider=msdaora.1;Data Source=YourSrcName;User ID=YourUserID;Password=YourPassword;"
Set rs=Server.CreateObject("ADODB.Recordset") ''创建Recordset对象
rs.CursorLocation=adUseClient ''设定记录集指针属性
''*设定一页内的记录总数,可根据需要进行调整
rs.PageSize=10
''*设置查询语句
