不惯用的html标签技巧
1.不准粘贴
onpaste="return false"
2.防止复制
oncopy="return false;" oncut="return false;"
3.IE地址栏前换成自己的图标
<link rel="Shortcut Icon" href="favicon.ico">
4.可以在收藏夹中显示出你的图标
<link rel="Bookmark" href="favicon.ico">
5.关闭输入法<input style="ime-mode:disabled">
6. 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>
7. 防止被人frame
<SCRIPT LANGUAGE=javascript><!--
if (top.location != self.location)top.location=self.location;
// --></SCRIPT>
8. 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 = -1
Response.ExpiresAbsolute = Now() - 1
Response.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");
9. 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>
9.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>
10. 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
