js 替换回车

str.replace(/\r\n/ig,"");
str.replace(/\r\n/g,"");

事件源对象

event.srcElement.tagName 
event.srcElement.type

捕获释放

event.srcElement.setCapture();  
event.srcElement.releaseCapture();

事件按键

event.keyCode 
event.shiftKey 
event.altKey 
event.ctrlKey

事件返回值

event.returnValue

鼠标位置

event.x 
event.y

窗体活动元素

document.activeElement

绑定事件

document.captureEvents(Event.KEYDOWN);

访问窗体元素

document.all("txt").focus(); 
document.all("txt").select();

窗体命令

document.execCommand

窗体COOKIE

document.cookie

菜单事件

document.oncontextmenu

创建元素

document.createElement("SPAN");

根据鼠标获得元素：

document.elementFromPoint(event.x,event.y).tagName=="TD 
document.elementFromPoint(event.x,event.y).appendChild(ms)

窗体图片

document.images[索引]

窗体事件绑定

document.onmousedown=scrollwindow;

元素

document.窗体.elements[索引]

对象绑定事件

document.all.xxx.detachEvent('onclick',a);

插件数目

navigator.plugins

取变量类型

typeof($js_libpath) == "undefined"

下拉框

下拉框.options[索引] 
下拉框.options.length

查找对象

document.getElementsByName("r1"); 
document.getElementById(id);

定时

timer=setInterval('scrollwindow()',delay); 
clearInterval(timer);

UNCODE编码

escape() ,unescape

父对象

obj.parentElement(dhtml) 
obj.parentNode(dom)

交换表的行

TableID.moveRow(2,1)

替换CSS

document.all.csss.href = "a.css";

并排显示

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

obj.execCommand

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  +=  "\r\n网页可见区域宽："+  document.body.clientWidth;   
s  +=  "\r\n网页可见区域高："+  document.body.clientHeight;   
s  +=  "\r\n网页可见区域高："+  document.body.offsetWeight  +"  (包括边线的宽)";

s  +=  "\r\n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,''))"

//消除图像工具栏

//无提示关闭
