宽屏版字体: 小|中|大|超大

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

简单邮件

快速转到位置

obj.scrollIntoView(true)

锚

<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

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。

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

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

地址栏图标

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

查看源码

关闭输入法

自动全选

ENTER键可以让光标移到下一个输入框

文本框的默认值

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

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

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

//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网页可见区域高："+ document.body.offsetHeight +" (包括边线的宽)";

s += "\r\n网页正文全文宽："+ document.body.scrollWidth;

s += "\r\n网页正文全文高："+ document.body.scrollHeight;

s += "\r\n网页被卷去的高："+ document.body.scrollTop;

s += "\r\n网页被卷去的左："+ document.body.scrollLeft;

s += "\r\n网页正文部分上："+ window.screenTop;

s += "\r\n网页正文部分左："+ window.screenLeft;

s += "\r\n屏幕分辨率的高："+ window.screen.height;

s += "\r\n屏幕分辨率的宽："+ window.screen.width;

s += "\r\n屏幕可用工作区高度："+ window.screen.availHeight;

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：+.)+[w-]+(/[w]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,''))"
