12. 怎样通过asp的手段来检查来访者是否用了代理
K/bJ4Uo <% if Request.ServerVariables("HTTP_X_FORWARDED_FOR")<>""
K/bJ4Uo then
K/bJ4Uo response.write "<font color=#FF0000>您通过了代理服务器，"& _
K/bJ4Uo "真实的IP为"&Request.ServerVariables("HTTP_X_FORWARDED_FOR")
K/bJ4Uo
K/bJ4Uo end if
K/bJ4Uo %>
13. 取得控件的绝对位置
//javascript
K/bJ4Uo <script language="javascript">
K/bJ4Uo function getIE(e){
K/bJ4Uo var t=e.offsetTop;
K/bJ4Uo var l=e.offsetLeft;
K/bJ4Uo while(e=e.offsetParent){
K/bJ4Uo t+=e.offsetTop;
K/bJ4Uo l+=e.offsetLeft;
K/bJ4Uo }
K/bJ4Uo alert("top="+t+"\nleft="+l);
K/bJ4Uo }
K/bJ4Uo </script>
//VBScript
K/bJ4Uo <script language="VBScript"><!--
K/bJ4Uo function getIE()
K/bJ4Uo dim t,l,a,b
K/bJ4Uo set a=document.all.img1

K/bJ4Uo wend
K/bJ4Uo msgbox "top="&t&chr(13)&"left="&l,64,"得到控件的位置"
K/bJ4Uo
K/bJ4Uo end function
K/bJ4Uo --></script>
14. 光标是停在文本框文字的最后
K/bJ4Uo <script language="javascript">
K/bJ4Uo function cc()
K/bJ4Uo {
K/bJ4Uo var e = event.srcElement;
K/bJ4Uo var r =e.createTextRange();
K/bJ4Uo r.moveStart('character',e.＆#118alue.length);
K/bJ4Uo r.collapse(true);
K/bJ4Uo r.select();
K/bJ4Uo }
K/bJ4Uo </script>
K/bJ4Uo <input type=text name=text1 ＆#118alue="123" onfocus="cc()">
K/bJ4Uo
15. 判断上一页的来源
K/bJ4Uo asp:
K/bJ4Uo request.servervariables("HTTP_REFERER")
java script:
K/bJ4Uo document.referrer
16. 最小化、最大化、关闭窗口
K/bJ4Uo <object id=hh1 classid="clsid:ADB880A6-D8FF-11CF-9377-00AA003B7A11">
K/bJ4Uo
K/bJ4Uo <param name="Command" ＆#118alue="Minimize"></object>
K/bJ4Uo
K/bJ4Uo <object id=hh2 classid="clsid:ADB880A6-D8FF-11CF-9377-00AA003B7A11">
K/bJ4Uo
K/bJ4Uo <param name="Command" ＆#118alue="Maximize"></object>
K/bJ4Uo
K/bJ4Uo <OBJECT id=hh3 classid="clsid:adb880a6-d8ff-11cf-9377-00aa003b7a11">
K/bJ4Uo
K/bJ4Uo <PARAM NAME="Command" ＆#118alue="Close"></OBJECT>
K/bJ4Uo
<input type=button ＆#118alue=最小化 ＆#111nclick=hh1.Click()>
K/bJ4Uo <input type=button ＆#118alue=最大化 ＆#111nclick=hh2.Click()>
K/bJ4Uo <input type=button ＆#118alue=关闭 ＆#111nclick=hh3.Click()>
K/bJ4Uo 本例适用于IE
17.
K/bJ4Uo <%
K/bJ4Uo '定义数据库连接的一些常量
K/bJ4Uo Const adOpenForwardOnly = 0 '游标只向前浏览记录，不支持分页、Recordset、BookMark
K/bJ4Uo Const 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、BookMark
K/bJ4Uo
K/bJ4Uo Const 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)。
K/bJ4Uo
K/bJ4Uo 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
K/bJ4Uo
Const adLockReadOnly = 1 '锁定类型，默认的，只读，不能作任何修改

18. 网页不会被缓存
K/bJ4Uo HTM网页
K/bJ4Uo <META HTTP-EQUIV="pragma" CONTENT="no-cache">
K/bJ4Uo <META HTTP-EQUIV="Cache-Control" CONTENT="no-cache, must-revalidate">
K/bJ4Uo
K/bJ4Uo <META HTTP-EQUIV="expires" CONTENT="Wed, 26 Feb 1997 08:21:57
K/bJ4Uo GMT">
K/bJ4Uo 或者<META HTTP-EQUIV="expires" CONTENT="0">
K/bJ4Uo ASP网页
K/bJ4Uo Response.Expires = -1
K/bJ4Uo Response.ExpiresAbsolute = Now() - 1
K/bJ4Uo Response.cachecontrol = "no-cache"
K/bJ4Uo PHP网页
K/bJ4Uo header("Expires: Mon, 26 Jul 1997 05:00:00 GMT");
K/bJ4Uo header("Cache-Control: no-cache, must-revalidate");
K/bJ4Uo header("Pragma: no-cache");
怎样让表单没有凹凸感？
K/bJ4Uo <input type=text style="border:1 solid #000000">
K/bJ4Uo 或
K/bJ4Uo <input type=text style="border-left:none; border-right:none; border-top:none;
K/bJ4Uo border-bottom: 1 solid #000000"></textarea>
<div><span>&<layer>的区别？
K/bJ4Uo <div>(division)用来定义大段的页面元素，会产生转行
K/bJ4Uo <span>用来定义同一行内的元素，跟<div>的唯一区别是不产生转行
K/bJ4Uo <layer>是ns的标记，ie不支持，相当于<div>
K/bJ4Uo 让弹出窗口总是在最上面:
K/bJ4Uo <body onblur="this.focus();">
不要滚动条?
K/bJ4Uo 让竖条没有:
K/bJ4Uo <body style='overflowcroll;overflow-y:hidden'>
K/bJ4Uo </body>
K/bJ4Uo 让横条没有:
K/bJ4Uo <body style='overflowcroll;overflow-x:hidden'>
K/bJ4Uo </body>
K/bJ4Uo 两个都去掉？更简单了
K/bJ4Uo <body scroll="no">
K/bJ4Uo </body>
怎样去掉图片链接点击后，图片周围的虚线？
K/bJ4Uo <a href="#" onFocus="this.blur()"><img src="logo.jpg"
K/bJ4Uo border=0></a>
电子邮件处理提交表单
K/bJ4Uo <form name="form1" method="post" action="mailto:****@***.com"
K/bJ4Uo enctype="text/plain">
K/bJ4Uo <input type=submit>
K/bJ4Uo </form>
在打开的子窗口刷新父窗口的代码里如何写？
K/bJ4Uo window.opener.location.reload()
如何设定打开页面的大小
K/bJ4Uo <body onload="top.resizeTo(300,200);">
在页面中如何加入不是满铺的背景图片,拉动页面时背景图不动
K/bJ4Uo <html><head>
K/bJ4Uo <STYLE>
K/bJ4Uo body
K/bJ4Uo {background-image:url(logo.gif); background-repeat:no-repeat; background-position:center
K/bJ4Uo }
K/bJ4Uo </STYLE>
K/bJ4Uo </head>
K/bJ4Uo <body bgproperties="fixed" >
K/bJ4Uo </body>
K/bJ4Uo </html>
19. 检查一段字符串是否全由数字组成
K/bJ4Uo <script language="javascript"><!--
K/bJ4Uo function checkNum(str){return str.match(/\D/)==null}
K/bJ4Uo alert(checkNum("1232142141"))
K/bJ4Uo alert(checkNum("123214214a1"))
K/bJ4Uo // --></script>
20. 获得一个窗口的大小
K/bJ4Uo document.body.clientWidth,document.body.clientHeight
21. 怎么判断是否是字符
K/bJ4Uo if (/[^\x00-\xff]/g.test(s)) alert("含有汉字");
K/bJ4Uo else alert("全是字符");
22.TEXTAREA自适应文字行数的多少
K/bJ4Uo <textarea rows=1 name=s1 cols=27 onpropertychange="this.style.posHeight=this.scrollHeight">
K/bJ4Uo
K/bJ4Uo </textarea>
23. 日期减去天数等于第二个日期
K/bJ4Uo <script language=javascript>
K/bJ4Uo function cc(dd,dadd)
K/bJ4Uo {
K/bJ4Uo //可以加上错误处理
K/bJ4Uo var a = new Date(dd)
K/bJ4Uo a = a.＆#118alueOf()
K/bJ4Uo a = a - dadd * 24 * 60 * 60 * 1000
K/bJ4Uo a = new Date(a)
K/bJ4Uo alert(a.getFullYear() + "年" + (a.getMonth() + 1) + "月" +
K/bJ4Uo a.getDate() + "日")
K/bJ4Uo }
K/bJ4Uo cc("12/23/2002",2)
K/bJ4Uo </script>
24. 选择了哪一个Radio
K/bJ4Uo <HTML><script language="vbscript">
K/bJ4Uo function checkme()
K/bJ4Uo for each ob in radio1
K/bJ4Uo if ob.checked then window.alert ob.＆#118alue
K/bJ4Uo next
K/bJ4Uo end function
K/bJ4Uo </script><BODY>
K/bJ4Uo <INPUT name="radio1" type="radio" ＆#118alue="style"
K/bJ4Uo checked>Style
K/bJ4Uo <INPUT name="radio1" type="radio" ＆#118alue="barcode">Barcode
K/bJ4Uo
K/bJ4Uo <INPUT type="button" ＆#118alue="check" ＆#111nclick="checkme()">
K/bJ4Uo
K/bJ4Uo </BODY></HTML>
25.获得本页url的request.servervariables("")集合
K/bJ4Uo Response.Write "<TABLE border=1><!-- Table Header --><TR><TD><B>Variables</B></TD><TD><B>＆#118alue</B></TD></TR>"
K/bJ4Uo
K/bJ4Uo for each ob in Request.ServerVariables
K/bJ4Uo Response.Write "<TR><TD>"&ob&"</TD><TD>"&Request.ServerVariables(ob)&"</TD></TR>"
K/bJ4Uo
K/bJ4Uo next
K/bJ4Uo Response.Write "</TABLE>"
26.

K/bJ4Uo %>
K/bJ4Uo 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
K/bJ4Uo <input ＆#111nkeydown="if(event.keyCode==13)event.keyCode=9">
28. 检测某个网站的链接速度：
K/bJ4Uo 把如下代码加入<body>区域中:
K/bJ4Uo <script language=javascript>
K/bJ4Uo tim=1
K/bJ4Uo setInterval("tim++",100)
K/bJ4Uo b=1
