精华ASP代码
1. οncοntextmenu="window.event.returnvalue=false" 将彻底屏蔽鼠标右键<table border οncοntextmenu=return(false)><td>no</table> 可用于Table
2. <body onselectstart="return false"> 取消选取、防止复制
3. οnpaste="return false" 不准粘贴
4. οncοpy="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"><!--if (window == top)top.location.href = "frames.htm"; //frames.htm为框架网页// --></script>
9. 防止被人frame<SCRIPT LANGUAGE=javascript><!-- if (top.location != self.location)top.location=self.location;// --></SCRIPT>
10. <noscript><iframe src=*.html></iframe></noscript> 网页将不能被另存为
11. <input type=button value=查看网页源代码 οnclick="window.location = view-source:+ http://www.csdn.net/'">
12. 怎样通过asp的手段来检查来访者是否用了代理<% if Request.ServerVariables("HTTP_X_FORWARDED_FOR")<>"" thenresponse.write "<font color=#FF0000>您通过了代理服务器,"& _"真实的IP为"&Request.ServerVariables("HTTP_X_FORWARDED_FOR")end if%>
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"><!--function getIE()dim t,l,a,bset a=document.all.img1t=document.all.img1.offsetTopl=document.all.img1.offsetLeftwhile a.tagName<>"BODY"set a = a.offsetParentt=t+a.offsetTopl=l+a.offsetLeftwendmsgbox "top="&t&chr(13)&"left="&l,64,"得到控件的位置"end function--></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" οnfοcus="cc()">
15. 判断上一页的来源asp:request.servervariables("HTTP_REFERER")
javascript:document.referrer
16. 最小化、最大化、关闭窗口<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=关闭 οnclick=hh3.Click()>本例适用于IE
17. <%定义数据库连接的一些常量Const adOpenForwardOnly = 0 游标只向前浏览记录,不支持分页、Recordset、BookMarkConst adOpenKeyset = 1 键集游标,其他用户对记录说做的修改将反映到记录集中,但其他用户增加或删除记录不会反映到记录集中。支持分页、Recordset、BookMarkConst adOpenDynamic = 2 动态游标功能最强,但耗资源也最多。用户对记录说做的修改,增加或删除记录都将反映到记录集中。支持全功能浏览(ACCESS不支持)。Const adOpenStatic = 3 静态游标,只是数据的一个快照,用户对记录说做的修改,增加或删除记录都不会反映到记录集中。支持向前或向后移动
Const adLockReadOnly = 1 锁定类型,默认的,只读,不能作任何修改Const adLockPessimistic = 2 当编辑时立即锁定记录,最安全的方式Const adLockOptimistic = 3 只有在调用Update方法时才锁定记录集,而在此前的其他操作仍可对当前记录进行更改、插入和删除等Const adLockBatchOptimistic = 4 当编辑时记录不会被锁定,而更改、插入和删除是在批处理方式下完成的
Const adCmdText = &H0001Const adCmdTable = &H0002%>
18. 网页不会被缓存HTM网页<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">ASP网页Response.Expires = -1Response.ExpiresAbsolute = Now() - 1Response.cachecontrol = "no-cache"PHP网页header("Expires: Mon, 26 Jul 1997 05:00:00 GMT");header("Cache-Control: no-cache, must-revalidate");header("Pragma: no-cache");
19. 检查一段字符串是否全由数字组成<script language="javascript"><!--function checkNum(str){return str.match(//D/)==null}alert(checkNum("1232142141"))alert(checkNum("123214214a1"))// --></script>
20. 获得一个窗口的大小document.body.clientWidth,document.body.clientHeight
21. 怎么判断是否是字符if (/[^/x00-/xff]/g.test(s)) alert("含有汉字");else alert("全是字符");
22.TEXTAREA自适应文字行数的多少<textarea rows=1 name=s1 cols=27 onpropertychange="this.style.posHeight=this.scrollHeight"></textarea>
23. 日期减去天数等于第二个日期<script language=javascript>function cc(dd,dadd){//可以加上错误处理var a = new Date(dd)a = a.valueOf()a = a - dadd * 24 * 60 * 60 * 1000a = new Date(a)alert(a.getFullYear() + "年" + (a.getMonth() + 1) + "月" + a.getDate() + "日")}cc("12/23/2002",2)</script>
24. 选择了哪一个Radio<HTML><script language="vbscript">function checkme()for each ob in radio1if ob.checked then window.alert ob.valuenextend 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>
25.获得本页url的request.servervariables("")集合Response.Write "<TABLE border=1><!-- Table Header --><TR><TD><B>Variables</B></TD><TD><B>value</B></TD></TR>"for each ob in Request.ServerVariablesResponse.Write "<TR><TD>"&ob&"</TD><TD>"&Request.ServerVariables(ob)&"</TD></TR>"nextResponse.Write "</TABLE>"
26.本机ip<%=request.servervariables("remote_addr")%>服务器名<%=Request.ServerVariables("SERVER_NAME")%>服务器IP<%=Request.ServerVariables("LOCAL_ADDR")%>服务器端口<%=Request.ServerVariables("SERVER_PORT")%>服务器时间<%=now%>IIS版本<%=Request.ServerVariables"SERVER_SOFTWARE")%>脚本超时时间<%=Server.ScriptTimeout%>本文件路径<%=server.mappath(Request.ServerVariables("SCRIPT_NAME"))%>服务器CPU数量<%=Request.ServerVariables("NUMBER_OF_PROCESSORS")%>服务器解译引擎<%=ScriptEngine & "/"& ScriptEngineMajorVersion &"."&ScriptEngineMinorVersion&"."& ScriptEngineBuildVersion %>服务器操作系统<%=Request.ServerVariables("OS")%>
27.ENTER键可以让光标移到下一个输入框<input οnkeydοwn="if(event.keyCode==13)event.keyCode=9">
28. 检测某个网站的链接速度:把如下代码加入<body>区域中:<script language=javascript>tim=1setInterval("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=测试中……> =》<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=urlif(tim>200){document.forms[0]["txt"+b].value="链接超时"}else{document.forms[0]["txt"+b].value="时间"+tim/10+"秒"}b++}function run(){for(var i=1;i<autourl.length;i++)document.write("<img src=http://"+autourl[i]+"/"+Math.random()+" width=1 height=1 οnerrοr=auto(http://";;;+autourl[i]+")>")}run()</script>
29. 各种样式的光标auto :标准光标default :标准箭头hand :手形光标wait :等待光标text :I形光标vertical-text :水平I形光标no-drop :不可拖动光标not-allowed :无效光标help :?帮助光标all-scroll :三角方向标move :移动标crosshair :十字标e-resizen-resizenw-resizew-resizes-resizese-resizesw-resize

2.修改contentType并下载gif等格式<%function dl(f,n)on error resume next
set s=CreateObject("Adodb.Stream") S.Mode=3 S.Type=1 S.Open s.LoadFromFile(server.mappath(f))if err.number>0 then response.write err.number & ":" & err.descriptionelseresponse.contentType="application/x-gzip"response.addheader "Content-Disposition:","attachment; filename=" & nresponse.binarywrite(s.Read(s.size))end ifend function
call dl("012922501.gif","t1.gif")%>
19. 检查一段字符串是否全由数字组成<script language="javascript"><!--function checkNum(str){return !//D/.test(str)}alert(checkNum("1232142141"))alert(checkNum("123214214a1"))// --></script>
20. 获得一个窗口的大小document.body.clientWidth,document.body.clientHeightdocument.body.offsetWidth,document.body.offsetHeight有时还需要知道window.screenTop,window.screenLeft
