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 <bodyoncontextmenu= "returnfalse" ondragstart= "returnfalse"

onselectstart= "returnfalse" onselect= "document.selection.empty()" oncopy= "document.selection.empty()" onbeforecopy= "returnfalse" 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 sdfs "

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

表格行指示

//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,’’))"
