1.獲得系統時間:
<%=now()%>
2.取得來訪用的IP:
<%=request.servervariables("remote_host")%>
3.獲得系統,瀏覽器版本:
<script>
window.document.write("版本："+navigator.appName+navigator.appVersion+" browser.")
</script>
4.去除IE混動條:
<body scroll="no">
<body style="overflow-y:hidden">
5.進入網站,跳出廣告:
<script language="javascript">
<!--
<!-- 注意更改文件所在路徑-->
window.open(''http://www.******.com','''',''height=200,width=300,top=0,left=30'');
// -->
</script>
6.隨機數:
<%randomize%>
<%=(int(rnd()*n)+1)%>
N爲可改變數
7.向上混動代碼:
<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.自動關閉網頁:
<script LANGUAGE="javascript">
<!--
setTimeout(''window.close();'', 10000); //60秒後關閉
// -->
</script>
<p align="center">本頁10秒後自動關閉,請注意刷新頁面</p>
9.隨機背景音樂:
<%randomize%>
<bgsound src="mids/<%=(int(rnd()*60)+1)%>.mid" loop="-1">
可以修改數字，限制調用個數，我這裏是６０個．
10.自動刷新本頁面:
<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+"秒後重刷本頁！"
else
curtime=cursec+"秒後重刷本頁！"
window.status=curtime
setTimeout("beginrefresh()",1000)
}
}
window.οnlοad=beginrefresh
file://-->
</script>
11.ACCESS數據庫連接:
<%
option explicit
dim startime,endtime,conn,connstr,db
startime=timer()
'更改數據庫名字
db="data/dvBBS5.mdb"
Set conn = Server.CreateObject("ADODB.Connection")
connstr="Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & Server.MapPath(db)
'如果你的服務器採用較老版本Access驅動，請用下面連接方法
'connstr="driver={Microsoft Access Driver (*.mdb)};dbq=" & Server.MapPath(db)
conn.Open connstr
function CloseDatabase
Conn.close
Set conn = Nothing
End function
%>
12.SQL數據庫連接:
<%
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.用鍵盤打開網頁代碼:
<script language="javascript">
function ctlent(eventobject)
{
if((event.ctrlKey && window.event.keyCode==13)||(event.altKey && window.event.keyCode==83))
{
window.open('網址','','')
}
}
</script>
這裏是Ctrl+Enter和Alt+S的代碼 自己查下鍵盤的ASCII碼再換就行
14.讓層不被控件覆蓋代碼:
<div z-Index:2><object ***></object></div> ＃ 前面
<div z-Index:1><object ***></object></div> ＃ 後面
<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廣告代碼:
<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彈出窗口小代碼:
<script language=vbscript>
msgbox"你還沒有註冊或登陸論壇","0","精品論壇"
location.href = "login.asp"
</script>

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

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寫文件某一行的函數
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

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.讀文件最後一行的函數
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))

40種網頁常用小技巧(JavaScript)
1. οncοntextmenu="window.event.returnValue=false" 將徹底屏蔽鼠標右鍵
<table border οncοntextmenu=return(false)><td>no</table> 可用於Table
2. <body onselectstart="return false"> 取消選取、防止複製
3. οnpaste="return false" 不準粘貼
4. οncοpy="return false;" oncut="return false;" 防止複製
5. <link rel="Shortcut Icon" href="favicon.ico"> IE地址欄前換成自己的圖標
6. <link rel="Bookmark" href="favicon.ico"> 可以在收藏夾中顯示出你的圖標
7. <input style="ime-mode:disabled"> 關閉輸入法
8. 永遠都會帶着框架
<script language="JavaScript"><!--
if (window == top)top.location.href = "frames.htm"; //frames.htm爲框架網頁
// --></script>
9. 防止被人frame
<SCRIPT LANGUAGE=JAVASCRIPT><!--
if (top.location != self.location)top.location=self.location;
// --></SCRIPT>
10. 網頁將不能被另存爲
<noscript><iframe src=*.html></iframe></noscript>
11. <input type=button value=查看網頁源代碼
οnclick="window.location = "view-source:"+ "http://www.pconline.com.cn"">
12.刪除時確認
<a href="javascript :if(confirm("確實要刪除嗎?"))location="boos.asp?&areyou=刪除&page=1"">刪除</a>
13. 取得控件的絕對位置
//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"><!--
function getIE()
dim t,l,a,b
set a=document.all.img1
t=document.all.img1.offsetTop
l=document.all.img1.offsetLeft
while a.tagName<>"BODY"
set a = a.offsetParent
t=t+a.offsetTop
l=l+a.offsetLeft
wend
msgbox "top="&t&chr(13)&"left="&l,64,"得到控件的位置"
end function
--></script>
14. 光標是停在文本框文字的最後
<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" οnfοcus="cc()">
15. 判斷上一頁的來源
javascript :
document.referrer
16. 最小化、最大化、關閉窗口
<object id=hh1 classid="clsid:ADB880A6-D8FF-11CF-9377-00AA003B7A11">
<param name="Command" value="Minimize"></object>
<object id=hh2 classid="clsid:ADB880A6-D8FF-11CF-9377-00AA003B7A11">
<param name="Command" value="Maximize"></object>
<OBJECT id=hh3 classid="clsid:adb880a6-d8ff-11cf-9377-00aa003b7a11">
<PARAM NAME="Command" VALUE="Close"></OBJECT>
<input type=button value=最小化 οnclick=hh1.Click()>
<input type=button value=最大化 οnclick=hh2.Click()>
<input type=button value=關閉 οnclick=hh3.Click()>
本例適用於IE
17.屏蔽功能鍵Shift,Alt,Ctrl
<script>
function look(){
if(event.shiftKey)
alert("禁止按Shift鍵!"); //可以換成ALT CTRL
}
document.οnkeydοwn=look;
</script>
18. 網頁不會被緩存
<META HTTP-EQUIV="pragma" CONTENT="no-cache">
<META HTTP-EQUIV="Cache-Control" CONTENT="no-cache, must-revalidate">
<META HTTP-EQUIV="expires" CONTENT="Wed, 26 Feb 1997 08:21:57 GMT">
或者<META HTTP-EQUIV="expires" CONTENT="0">
19.怎樣讓表單沒有凹凸感？
<input type=text style="border:1 solid #000000">
或
<input type=text style="border-left:none; border-right:none; border-top:none; border-bottom:
1 solid #000000"></textarea>
20.<div><span>&<layer>的區別？
<div>(division)用來定義大段的頁面元素，會產生轉行
<span>用來定義同一行內的元素，跟<div>的唯一區別是不產生轉行
<layer>是ns的標記，ie不支持，相當於<div>
21.讓彈出窗口總是在最上面:
<body οnblur="this.focus();">
22.不要滾動條?
讓豎條沒有:
<body style="overflow:scroll;overflow-y:hidden">
</body>
讓橫條沒有:
<body style="overflow:scroll;overflow-x:hidden">
</body>
兩個都去掉？更簡單了
<body scroll="no">
</body>
23.怎樣去掉圖片鏈接點擊後，圖片周圍的虛線？
<a href="#" onFocus="this.blur()"><img src="logo.jpg" border=0></a>
24.電子郵件處理提交表單
<form name="form1" method="post" action="mailto:****@***.com" enctype="text/plain">
<input type=submit>
</form>
25.在打開的子窗口刷新父窗口的代碼裏如何寫？
window.opener.location.reload()
26.如何設定打開頁面的大小
<body οnlοad="top.resizeTo(300,200);">
打開頁面的位置<body οnlοad="top.moveBy(300,200);">
27.在頁面中如何加入不是滿鋪的背景圖片,拉動頁面時背景圖不動
<STYLE>
body
{background-image:url(logo.gif); background-repeat:no-repeat;
background-position:center;background-attachment: fixed}
</STYLE>
28. 檢查一段字符串是否全由數字組成
<script language="Javascript"><!--
function checkNum(str){return str.match(//D/)==null}
alert(checkNum("1232142141"))
alert(checkNum("123214214a1"))
// --></script>
29. 獲得一個窗口的大小
document.body.clientWidth; document.body.clientHeight
30. 怎麼判斷是否是字符
if (/[^/x00-/xff]/g.test(s)) alert("含有漢字");
else alert("全是字符");
31.TEXTAREA自適應文字行數的多少
<textarea rows=1 name=s1 cols=27 onpropertychange="this.style.posHeight=this.scrollHeight">
</textarea>
32. 日期減去天數等於第二個日期
<script language=Javascript>
function cc(dd,dadd)
{
//可以加上錯誤處理
var a = new Date(dd)
a = a.valueOf()
a = a - dadd * 24 * 60 * 60 * 1000
a = new Date(a)
alert(a.getFullYear() + "年" + (a.getMonth() + 1) + "月" + a.getDate() + "日")
}
cc("12/23/2002",2)
</script>
33. 選擇了哪一個Radio
<HTML><script language="vbscript">
function checkme()
for each ob in radio1
if ob.checked then window.alert ob.value
next
end function
</script><BODY>
<INPUT name="radio1" type="radio" value="style" checked>Style
<INPUT name="radio1" type="radio" value="barcode">Barcode
<INPUT type="button" value="check" οnclick="checkme()">
</BODY></HTML>
34.腳本永不出錯
<SCRIPT LANGUAGE="JavaScript">
<!-- Hide
function killErrors() {
return true;
}
window.onerror = killErrors;
// -->
</SCRIPT>
35.ENTER鍵可以讓光標移到下一個輸入框
<input οnkeydοwn="if(event.keyCode==13)event.keyCode=9">
36. 檢測某個網站的鏈接速度：
把如下代碼加入<body>區域中:
<script language=Javascript>
tim=1
setInterval("tim++",100)
b=1
var autourl=new Array()
autourl[1]="www.njcatv.net"
autourl[2]="javacool.3322.net"
autourl[3]="www.sina.com.cn"
autourl[4]="www.nuaa.edu.cn"
autourl[5]="www.cctv.com"
function butt(){
document.write("<form name=autof>")
for(var i=1;i<autourl.length;i++)
document.write("<input type=text name=txt"+i+" size=10 value=測試中……> =》<input type=text
name=url"+i+" size=40> =》<input type=button value=GO
οnclick=window.open(this.form.url"+i+".value)><br>")
document.write("<input type=submit value=刷新></form>")
}
butt()
function auto(url){
document.forms[0]["url"+b].value=url
if(tim>200)
{document.forms[0]["txt"+b].value="鏈接超時"}
else
{document.forms[0]["txt"+b].value="時間"+tim/10+"秒"}
b++
}
function run(){for(var i=1;i<autourl.length;i++)document.write("<img src=http://"+autourl+"/"+Math.random()+" width=1 height=1
οnerrοr=auto("http://"+autourl+"")>")}
run()</script>
37. 各種樣式的光標
auto ：標準光標
default ：標準箭頭
hand ：手形光標
wait ：等待光標
text ：I形光標
vertical-text ：水平I形光標
no-drop ：不可拖動光標
not-allowed ：無效光標
help ：?幫助光標
all-scroll ：三角方向標
move ：移動標
crosshair ：十字標
e-resize
n-resize
nw-resize
w-resize
s-resize
se-resize
sw-resize
38.頁面進入和退出的特效
進入頁面<meta http-equiv="Page-Enter" content="revealTrans(duration=x, transition=y)">
推出頁面<meta http-equiv="Page-Exit" content="revealTrans(duration=x, transition=y)">
這個是頁面被載入和調出時的一些特效。duration表示特效的持續時間，以秒爲單位。transition表示使用哪種特效，取值爲1-23:
0 矩形縮小
1 矩形擴大
2 圓形縮小
3 圓形擴大
4 下到上刷新
5 上到下刷新
6 左到右刷新
7 右到左刷新

23 以上22種隨機選擇一種
39.在規定時間內跳轉
<META http-equiv=V="REFRESH" content="5;URL=http://www.51js.com">
40.網頁是否被檢索
<meta name="ROBOTS" content="屬性值">
其中屬性值有以下一些:
屬性值爲"all": 文件將被檢索，且頁上鍊接可被查詢；
屬性值爲"none": 文件不被檢索，而且不查詢頁上的鏈接；
屬性值爲"index": 文件將被檢索；
