整理了一些初学者常用的ASP代码

By | 2006 年 6 月 16 日

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”>
<!–
<!– 注意更改文件所在路径–>
window.open(”http://www.XXXXXX.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”>
<!–
setTimeout(”window.close();”, 10000); //60秒后关闭
// –>
</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)
}
}
window.onload=beginrefresh
file://–>
</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 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

JSP显示在线人数代码

/**
* 编写以下SessionCounter.java
* 并编译为SessiionCounter.class
* 然后放到你的网站的classpath的
* SessionCount(自己建立此目录)下面
*/
package SessionCount;
import javax.servlet.*;
import javax.servlet.http.*;
public class SessionCounter implements HttpSessionListener {
private static int activeSessions = 0;
public void sessionCreated(HttpSessionEvent se) {
activeSessions++;
}
public void sessionDestroyed(HttpSessionEvent se) {
if(activeSessions > 0)
activeSessions–;
}
public static int getActiveSessions() {
return activeSessions;
}
}
接着建立online.jsp文件用于显示在线人数
<%@ page import=”SessionCount.SessionCounter” %>
在线:<%= SessionCounter.getActiveSessions() %>
然后需要在你的网站的WEB-INF中建立web.xml
文件内容如下:
<!– Web.xml –>
<?xml version=”1.0″ encoding=”ISO-8859-1″?>
<!DOCTYPE web-app
PUBLIC “-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN”
“http://java.sun.com/j2ee/dtds/web-app_2.3.dtd”>
<web-app>
<!– Listeners –>
<listener>
<listener-class>
SessionCount.SessionCounter
</listener-class>
</listener>
</web-app>
然后重新启动你的应用服务器,访问online.jsp检查是否显示正确。
在线人数统计代码(PHP+文本)
&lt;?php

$filename=”online.txt”;
$onlinetime=900; //多长时间算掉线,单位:秒

$online_id=file($filename);
$total_online=count($online_id);
$ip = getIp();
$nowtime=time();

//删除已掉线已列入的用户
for($i=0;$i&lt;$total_online;$i++){
$oldip=explode(“|*|”,$online_id[$i]);

$hasonlinetime=$nowtime-$oldip[0];
if($hasonlinetime&lt;$onlinetime and $ip!=$oldip[1]) $nowonline[]=$online_id[$i];
}

//记录当前IP用户
$nowonline[]=$nowtime.”|*|”.$ip.”|*|”;

//得到当前在线人数并重新写入文件
$total_online=count($nowonline);
$fp=fopen($filename,”w”;
rewind($fp);
for($i=0;$i&lt;$total_online;$i++){

fputs($fp,$nowonline[$i]);
fputs($fp,”n”;
}
fclose($fp);

if($total_online==0)$total_online=1;
echo$total_online;

?&gt;
调用代码为:
 当前在线:<%=Application(“Count”)%>人 

记得代码要用在ASP页中!
