篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了网页中一些比较隐蔽的用法相关的知识，希望对你有一定的参考价值。

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.οnmοusedοwn=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 οncοntextmenu="return false" οndragstart="return false" onselectstart ="return false" οnselect="document.selection.empty()" οncοpy="document.selection.empty()" onbeforecopy="return false"οnmοuseup="document.selection.empty()>

禁止粘贴
<input type=text οnpaste="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 οnclick="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" οnfοcus="this.select()">

ENTER键可以让光标移到下一个输入框
<input οnkeydοwn="if(event.keyCode==13)event.keyCode=9">

文本框的默认值
<input type=text value="123" οnfοcus="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 οnlοad="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 οnmοuseοver="this.bgColor='#f0f0f0'" οnmοuseοut="this.bgColor='#ffffff'">

//各种尺寸

//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：οnkeyup="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： οnkeyup="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：οnkeyup="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：οnkeyup="value=value.replace(/[/W]/g,'') "onbeforepaste="clipboardData.setData('text',clipboardData.getData('text').replace(/[^/d]/g,''))"
