1. oncontextmenu="window.event.returnValue=false" 将彻底屏蔽鼠标右键
<table border oncontextmenu=return(false)><td>no</table> 可用于Table2. <body onselectstart="return false"> 取消选取、防止复制
3. onpaste="return false" 不准粘贴
4. oncopy="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

<div>(division)用来定义大段的页面元素，会产生转行
<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
<layer>是ns的标记，ie不支持，相当于<div>让弹出窗口总是在最上面:
<body onblur="this.focus();">不要滚动条?
让竖条没有:
<body style='overflow:scroll;overflow-y:hidden'>
</body>
让横条没有:
<body style='overflow:scroll;overflow-x:hidden'>

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>

a = a.valueOf()
a = a - dadd * 24 * 60 * 60 * 1000

// trim 去除字符串两端的空格

// 起死原因：以文本框为例，当一个文本框的输入不符合条件时，这时，鼠标点击另一个文本框，触发第一个文本框的离开事件
