Posted on 2007-03-22 16:07 Jaunt 閱讀(317) 評論(0) 編輯收藏所屬分類: JavaScript

事件源對象
event.srcElement.tagName
event.srcElement.type
捕獲釋放
event.srcElement.setCapture();?
event.srcElement.releaseCapture();?
事件按鍵
event.keyCode
event.shiftKey
event.altKey
event.ctrlKey
事件返回值
event.returnValue
鼠標位置
event.x
event.y
窗體活動元素
document.activeElement
綁定事件
document.captureEvents(Event.KEYDOWN);
訪問窗體元素
document.all("txt").focus();
document.all("txt").select();
窗體命令
document.execCommand
窗體COOKIE
document.cookie
菜單事件
document.oncontextmenu
創建元素
document.createElement("SPAN");?
根據鼠標獲得元素：
document.elementFromPoint(event.x,event.y).tagName=="TD
document.elementFromPoint(event.x,event.y).appendChild(ms)?
窗體圖片
document.images[索引]
窗體事件綁定
document.onmousedown=scrollwindow;
元素
document.窗體.elements[索引]
對象綁定事件
document.all.xxx.detachEvent('onclick',a);
插件數目
navigator.plugins
取變量類型
typeof($js_libpath) == "undefined"
下拉框
下拉框.options[索引]
下拉框.options.length
查找對象
document.getElementsByName("r1");
document.getElementById(id);
定時
timer=setInterval('scrollwindow()',delay);
clearInterval(timer);
UNCODE編碼
escape() ,unescape
父對象
obj.parentElement(dhtml)
obj.parentNode(dom)
交換表的行
TableID.moveRow(2,1)

替換CSS
document.all.csss.href="a.css";

并排顯示
display:inline

隱藏焦點
hidefocus=true

根據寬度換行
style="word-break:break-all"

自動刷新
<meta HTTP-EQUIV="refresh" CONTENT="8;URL=http://c98.yeah.net">

簡單郵件
<a? href=" mailto:aaa@bbb.com?subject=ccc&body=xxxyyy ">?

快速轉到位置
obj.scrollIntoView(true)

錨
<a name="first">
<a href="#first">anchors</a>

網頁傳遞參數
location.search();

可編輯
obj.contenteditable=true

執行菜單命令
obj.execCommand

雙字節字符
/[^\x00-\xff]/
漢字
/[\u4e00-\u9fa5]/

讓英文字符串超出表格寬度自動換行
word-wrap: break-word; word-break: break-all;

透明背景
<IFRAME src="1.htm" width=300 height=180 allowtransparency></iframe>

獲得style內容
obj.style.cssText

HTML標簽
document.documentElement.innerHTML

第一個style標簽
document.styleSheets[0]

style標簽里的第一個樣式
document.styleSheets[0].rules[0]

防止點擊空鏈接時，頁面往往重置到頁首端。
<a href="javascript:function()">word</a>

上一網頁源
asp:
request.servervariables("HTTP_REFERER")
javascript:
document.referrer

釋放內存
CollectGarbage();

禁止右鍵
document.oncontextmenu = function() { return false;}

禁止保存
<noscript><iframe src="*.htm"></iframe></noscript>

禁止選取

<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()>?

禁止粘貼
<input type=text onpaste="return false">

地址欄圖標
<link rel="Shortcut Icon" href="favicon.ico">
favicon.ico 名字最好不變16*16的16色,放虛擬目錄根目錄下

收藏欄圖標
<link rel="Bookmark" href="favicon.ico">

查看源碼
<input type=button value=查看網頁源代碼 onclick="window.location = 'view-source:'+ 'http://www.csdn.net/'">

關閉輸入法
<input style="ime-mode:disabled">

自動全選
<input type=text name=text1 value="123" onfocus="this.select()">

ENTER鍵可以讓光標移到下一個輸入框
<input onkeydown="if(event.keyCode==13)event.keyCode=9">

文本框的默認值
<input type=text value="123" onfocus="alert(this.defaultValue)">

title換行
obj.title = "123&#13sdfs&#32"

獲得時間所代表的微秒
var n1 = new Date("2004-10-10".replace(/-/g, "\/")).getTime()

窗口是否關閉
win.closed

checkbox扁平
<input type=checkbox style="position: absolute; clip:rect(5px 15px 15px 5px)"><br>

獲取選中內容
document.selection.createRange().duplicate().text

自動完成功能
<input? type=text? autocomplete=on>打開該功能?
<input? type=text? autocomplete=off>關閉該功能???

窗口最大化
<body onload="window.resizeTo(window.screen.width - 4,window.screen.height-50);window.moveTo(-4,-4)">

無關閉按鈕IE
window.open("aa.htm", "meizz", "fullscreen=7");

統一編碼/解碼
alert(decodeURIComponent(encodeURIComponent("http://你好.com?as= hehe")))
encodeURIComponent對":"、"/"、";" 和 "?"也編碼

表格行指示
<tr onmouseover="this.bgColor='#f0f0f0'" onmouseout="this.bgColor='#ffffff'">

//正則匹配

匹配中文字符的正則表達式：?[\u4e00-\u9fa5] 
匹配雙字節字符(包括漢字在內)：[^\x00-\xff] 
匹配空行的正則表達式：\n[\s|?]*\r 
匹配HTML標記的正則表達式：/<(.*)>.*<\/\1>|<(.*)?\/>/? 
匹配首尾空格的正則表達式：(^\s*)|(\s*$)（像vbscript那樣的trim函數） 
匹配Email地址的正則表達式：\w+([-+.]\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)* 
匹配網址URL的正則表達式：http://([\w-]+\.)+[\w-]+(/[\w-?./?%&=]*)? 
以下是例子： 
利用正則表達式限制網頁表單里的文本框輸入內容： 
用正則表達式限制只能輸入中文：onkeyup="value=value.replace(/[^\u4E00-\u9FA5]/g,'')"?onbeforepaste="clipboardData.setData('text',clipboardData.getData('text').replace(/[^\u4E00-\u9FA5]/g,''))"
1.用正則表達式限制只能輸入全角字符：?onkeyup="value=value.replace(/[^\uFF00-\uFFFF]/g,'')"?onbeforepaste="clipboardData.setData('text',clipboardData.getData('text').replace(/[^\uFF00-\uFFFF]/g,''))"
2.用正則表達式限制只能輸入數字：onkeyup="value=value.replace(/[^\d]/g,'')?"onbeforepaste="clipboardData.setData('text',clipboardData.getData('text').replace(/[^\d]/g,''))"
3.用正則表達式限制只能輸入數字和英文：onkeyup="value=value.replace(/[\W]/g,'')?"onbeforepaste="clipboardData.setData('text',clipboardData.getData('text').replace(/[^\d]/g,''))"
