访问窗体元素
document.all("txt").focus();
document.all("txt").select();
窗体命令

交换表的行
TableID.moveRow(2,1)
替换CSS

display:inline
隐藏焦点
hidefocus=true
根据宽度换行
style="word-break:break-all"
自动刷新
<meta HTTP-EQUIV="refresh" CONTENT="8;URL=http://c98.yeah.net">
简单邮件
<a href="mailto:aaa@bbb.com?subject=ccc&body=xxxyyy">
快速转到位置
obj.scrollIntoView(true)
锚
<a name="first">
<a href="#first">anchors</a>
网页传递参数
location.search();
可编辑
obj.contenteditable=true
执行菜单命令

双字节字符
/[^x00-xff]/
汉字
/[u4e00-u9fa5]/
让英文字符串超出表格宽度自动换行
word-wrap: break-word; word-break: break-all;
透明背景
<IFRAME src="1.htm" width=300 height=180 allowtransparency></iframe>
获得style内容
obj.style.cssText
HTML标签
document.documentElement.innerHTML
第一个style标签
document.styleSheets[0]
style标签里的第一个样式
document.styleSheets[0].rules[0]
防止点击空链接时，页面往往重置到页首端。
<a href="javascript:function()">word</a>
上一网页源
asp:
request.servervariables("HTTP_REFERER")
javascript:
document.referrer
释放内存
CollectGarbage();
禁止右键
document.oncontextmenu = function() { return false;}
禁止保存
<noscript><iframe src="*.htm"></iframe></noscript>
禁止选取<body oncontextmenu="return false" ondragstart="return false" onselectstart ="return false" onselect="document.selection.empty()" oncopy="document.selection.empty()" onbeforecopy="return false"onmouseup="document.selection.empty()>
禁止粘贴
<input type=text onpaste="return false">
地址栏图标
<link rel="Shortcut Icon" href="favicon.ico">
favicon.ico 名字最好不变16*16的16色,放虚拟目录根目录下
收藏栏图标
<link rel="Bookmark" href="favicon.ico">
查看源码
<input type=button value=查看网页源代码 onclick="window.location = 'view-source:'+ 'http://www.csdn.net/'">
关闭输入法
<input style="ime-mode:disabled">
自动全选
<input type=text name=text1 value="123" onfocus="this.select()">
ENTER键可以让光标移到下一个输入框
<input onkeydown="if(event.keyCode==13)event.keyCode=9">
文本框的默认值
<input type=text value="123" onfocus="alert(this.defaultValue)">
title换行
obj.title = "123&#13sdfs&#32"
获得时间所代表的微秒
var n1 = new Date("2004-10-10".replace(/-/g, "/")).getTime()
窗口是否关闭
win.closed
checkbox扁平
<input type=checkbox style="position: absolute; clip:rect(5px 15px 15px 5px)"><br>
获取选中内容
document.selection.createRange().duplicate().text
自动完成功能
<input type=text autocomplete=on>打开该功能
<input type=text autocomplete=off>关闭该功能
窗口最大化
<body onload="window.resizeTo(window.screen.width - 4,window.screen.height-50);window.moveTo(-4,-4)">
无关闭按钮IE
window.open("aa.htm", "meizz", "fullscreen=7");
统一编码/解码
alert(decodeURIComponent(encodeURIComponent("http://你好.com?as= hehe")))
encodeURIComponent对":"、"/"、";" 和 "?"也编码
表格行指示
<tr onmouseover="this.bgColor='#f0f0f0'" onmouseout="this.bgColor='#ffffff'">

//各种尺寸

s  +=  "rn网页可见区域宽："+  document.body.clientWidth;  
s  +=  "rn网页可见区域高："+  document.body.clientHeight;  
s  +=  "rn网页可见区域高："+  document.body.offsetWeight  +"  (包括边线的宽)";  
s  +=  "rn网页可见区域高："+  document.body.offsetHeight  +"  (包括边线的宽)";  
s  +=  "rn网页正文全文宽："+  document.body.scrollWidth;  
s  +=  "rn网页正文全文高："+  document.body.scrollHeight;

s  +=  "rn网页被卷去的左："+  document.body.scrollLeft;  
s  +=  "rn网页正文部分上："+  window.screenTop;  
s  +=  "rn网页正文部分左："+  window.screenLeft;  
s  +=  "rn屏幕分辨率的高："+  window.screen.height;  
s  +=  "rn屏幕分辨率的宽："+  window.screen.width;  
s  +=  "rn屏幕可用工作区高度："+  window.screen.availHeight;  
s  +=  "rn屏幕可用工作区宽度："+  window.screen.availWidth;

//过滤数字

//特殊用途

//不缓存

//正则匹配

匹配中文字符的正则表达式： [u4e00-u9fa5]
匹配双字节字符(包括汉字在内)：[^x00-xff]
匹配空行的正则表达式：n[s| ]*r
匹配HTML标记的正则表达式：/<(.*)>.*</1>|<(.*) />/ 
匹配首尾空格的正则表达式：(^s*)|(s*$)（像vbscript那样的trim函数）
匹配Email地址的正则表达式：w+([-+.]w+)*@w+([-.]w+)*.w+([-.]w+)*
匹配网址URL的正则表达式：http://([w-]+.)+[w-]+(/[w- ./?%&=]*)? 
以下是例子：
利用正则表达式限制网页表单里的文本框输入内容：
用正则表达式限制只能输入中文：onkeyup="value=value.replace(/[^u4E00-u9FA5]/g,'')" onbeforepaste="clipboardData.setData('text',clipboardData.getData('text').replace(/[^u4E00-u9FA5]/g,''))"
1.用正则表达式限制只能输入全角字符： onkeyup="value=value.replace(/[^uFF00-uFFFF]/g,'')" onbeforepaste="clipboardData.setData('text',clipboardData.getData('text').replace(/[^uFF00-uFFFF]/g,''))"
2.用正则表达式限制只能输入数字：onkeyup="value=value.replace(/[^d]/g,'') "onbeforepaste="clipboardData.setData('text',clipboardData.getData('text').replace(/[^d]/g,''))"
3.用正则表达式限制只能输入数字和英文：onkeyup="value=value.replace(/[W]/g,'') "onbeforepaste="clipboardData.setData('text',clipboardData.getData('text').replace(/[^d]/g,''))"
