原谅他77次阿娇阿sa:网页制作必备之初级代码
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:
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.******.com‘,‘‘‘‘,‘‘height=200,width=300,top=0,left=30‘‘);
// -->
6.随机数:
<%randomize%>
<%=(int(rnd()*n)+1)%>
N为可改变数
7.向上混动代码:
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:
<%randomize%>
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:
function ctlent(eventobject)
{
if((event.ctrlKey && window.event.keyCode==13)||(event.altKey && window.event.keyCode==83))
{
window.open(‘网址‘,‘‘,‘‘)
}
}
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:
# 前面 # 后面
15.FLASH广告代码:
16.VBS弹出窗口小代码:
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
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)

40种网页常用小技巧(JavaScript)
1. oncontextmenu="window.event.returnValue=false" 将彻底屏蔽鼠标右键
no |
2.
取消选取、防止复制
3. onpaste="return false" 不准粘贴
4. oncopy="return false;" oncut="return false;" 防止复制
5. IE地址栏前换成自己的图标
6. 可以在收藏夹中显示出你的图标
7. 关闭输入法
8. 永远都会带着框架
9. 防止被人frame
10. 网页将不能被另存为
11.
onclick="window.location = "view-source:"+ "http://www.pconline.com.cn"">
12.删除时确认
13. 取得控件的绝对位置
//Javascript
function getIE(e){
var t=e.offsetTop;
var l=e.offsetLeft;
while(e=e.offsetParent){
t+=e.offsetTop;
l+=e.offsetLeft;
}
alert("top="+t+"/nleft="+l);
}
//VBScript
14. 光标是停在文本框文字的最后
function cc()
{
var e = event.srcElement;
var r =e.createTextRange();
r.moveStart("character",e.value.length);
r.collapse(true);
r.select();
}
15. 判断上一页的来源
javascript :
document.referrer
16. 最小化、最大化、关闭窗口
本例适用于IE
17.屏蔽功能键Shift,Alt,Ctrl
function look(){
if(event.shiftKey)
alert("禁止按Shift键!"); //可以换成ALT CTRL
}
document.onkeydown=look;
