JavaScript

HTML JavaScript 正则表达式 IE Microsoft

获取事件源对象

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();

-- document.all 好像是不推荐使用的

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]

--这么用不太现实吧，窗体里要是元素特别多，还得一个一个数啊？除非万不得已

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";

-- 实现动态换肤的基础

并排显示（内联）

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" C>

简单邮件

<a  href="[email=aaa@bbb.com?subject=ccc&body=xxxyyy]mailto:aaa@bbb.com?subject=ccc&body=xxxyyy[/email]">

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>

-- 这个用法还是不建议的，显示的还是由CSS管理，不要hardcode

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 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

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

<input type=text onkeypress="return event.keyCode>=48&&event.keyCode<=57||(this.value.indexOf('.')<0?event.keyCode==46:false)" onpaste="return !clipboardData.getData('text').match(/\D/)" ondragenter="return false">

特殊用途

<input type=button value=导入收藏夹 onclick="window.external.ImportExportFavorites(true,'http://localhost');"> 
<input type=button value=导出收藏夹 onclick="window.external.ImportExportFavorites(false,'http://localhost');"> 
<input type=button value=整理收藏夹 onclick="window.external.ShowBrowserUI('OrganizeFavorites', null)"> 
<input type=button value=语言设置 onclick="window.external.ShowBrowserUI('LanguageDialog', null)"> 
<input type=button value=加入收藏夹 onclick="window.external.AddFavorite('http://www.google.com/', 'google')"> 
<input type=button value=加入到频道 onclick="window.external.addChannel('http://www.google.com/')"> 
<input type=button value=加入到频道 onclick="window.external.showBrowserUI('PrivacySettings',null)">

不缓存

<META HTTP-EQUIV="pragma" CONTENT="no-cache"> 
<META HTTP-EQUIV="Cache-Control" CONTENT="no-cache, must-revalidate"> 
<META HTTP-EQUIV="expires" CONTENT="0">

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- ./?%&=]*)?

正则表达式例子：

//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

<IMG SRC="mypicture.jpg" HEIGHT="100px" WIDTH="100px" GALLERYIMG="false"> or 
<head> 
<meta http-equiv="imagetoolbar" content="no"> 
</head>

无提示关闭

function Close() { 
      var ua=navigator.userAgent;
      var ie=navigator.appName=="Microsoft Internet Explorer"?true:false; 
      if(ie) { 
            var IEversion=parseFloat(ua.substring(ua.indexOf("MSIE ")+5,ua.indexOf(";",ua.indexOf("MSIE ")))) 
            if(IEversion< 5.5) { 
                  var str = '<object id=noTipClose classid="clsid:ADB880A6-D8FF-11CF-9377-00AA003B7A11">' 
                  str += '<param name="Command" value="Close"></object>'; 
                  document.body.insertAdjacentHTML("beforeEnd", str); 
                  document.all.noTipClose.Click(); 
            } else { 
                  window.opener =null; 
                  window.close(); 
            } 
      }else { 
            window.close() 
      } 
}

取得控件得绝对位置(1)

<script language="javascript">
    function getoffset(e){
        var t = e.offsetTop;
        var l = e.offsetLeft;
        while (e = e.offsetParent) {
            t += e.offsetTop;
            l += e.offsetLeft;
        }
        var rec = new Array(1);
        rec[0] = t;
        rec[1] = l;
        return rec
    }
</script>

获得控件的绝对位置(2)

oRect = obj.getBoundingClientRect();
oRect.left
oRect.

光标停在文字最后

<script language="javascript">
    function cc(){
        var e = event.srcElement;
        var r = e.createTextRange();
        r.moveStart('character', e.value.length);
        r.collapse(true);
        r.select();
    }
</script>
<input type=text name=text1 value="123" onfocus="cc()">

//页面进入和退出的特效
进入页面

<meta http-equiv="Page-Enter" content="revealTrans(duration=x, transition=y)">

推出页面
