网页制作必备之初级代码

来源：互联网发布：linux系清除终端记录编辑：程序博客网时间：2024/04/29 15:51

以下是一些常用的代码，仅供参考：

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">

window.open(''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>

</script>

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 ***></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.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:
<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
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
<table border oncontextmenu=return(false)><td>no</table> 可用于Table

2. <body onselectstart="return false"> 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. <link rel="Shortcut Icon" href="favicon.ico"> IE地址栏前换成自己的图标

6. <link rel="Bookmark" href="favicon.ico"> 可以在收藏夹中显示出你的图标

7. <input style="ime-mode:disabled"> 关闭输入法

8. 永远都会带着框架
<script language="JavaScript"></script>

9. 防止被人frame
<SCRIPT LANGUAGE=JAVASCRIPT></SCRIPT>

10. 网页将不能被另存为
<noscript><iframe src=*.html></iframe></noscript>

11. <input type=button value=查看网页源代码
onclick="window.location = "view-source:"+ "http://www.pconline.com.cn"">

12.删除时确认
<a href="javascript :if(confirm("确实要删除吗?"))location="boos.asp?&areyou=删除&page=1"">删除</a>

13. 取得控件的绝对位置
//Javascript
<script language="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);
}
</script>

//VBScript
<script language="VBScript"></script>

14. 光标是停在文本框文字的最后
<script language="javascript">
function cc()
{
var e = event.srcElement;
var r =e.createTextRange();
r.moveStart("character",e.value.length);
r.collapse(true);
r.select();
}
</script>
<input type=text name=text1 value="123" onfocus="cc()">
