[推荐]ASP初学者常用的代码

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: <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.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">  </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) } } 　

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.动网FLASH广告代码: <object classid="clsid27CDB6E-AE6D-11cf-96B8-444553540000" codebase="http:
