Javascript技巧參考
事件源對(duì)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

訪問(wèn)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(chuàng)建元素
document.createElement("SPAN");
根據(jù)鼠標(biāo)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(duì)象綁定事件
document.all.xxx.detachEvent('onclick',a);
插件數(shù)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(duì)象
document.getElementsByName("r1");
document.getElementById(id);

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(diǎn)
hidefocus=true
根據(jù)寬度換行
style="word-break:break-all"
自動(dòng)刷新
<meta HTTP-EQUIV="refresh" CONTENT="8;URL=http://c98.yeah.net">

網(wǎng)頁(yè)傳遞參數(shù)
location.search();
可編輯
obj.contenteditable=true
執(zhí)行菜單命令
obj.execCommand
雙字節(jié)字符
/[^\x00-\xff]/
漢字
/[\u4e00-\u9fa5]/
讓英文字符串超出表格寬度自動(dòng)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(nèi)容
obj.style.cssText
HTML標(biāo)簽
document.documentElement.innerHTML
第一個(gè)style標(biāo)簽
document.styleSheets[0]
style標(biāo)簽里的第一個(gè)樣式
document.styleSheets[0].rules[0]
防止點(diǎn)擊空鏈接時(shí)，頁(yè)面往往重置到頁(yè)首端。
<a href="javascript:function()">word</a>
上一網(wǎng)頁(yè)源
asp:
request.servervariables("HTTP_REFERER")
javascript:
document.referrer
釋放內(nèi)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(biāo)
<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

關(guān)閉輸入法
<input style="ime-mode:disabled">
自動(dòng)全選
<input type=text name=text1 value="123" onfocus="this.select()">
ENTER鍵可以讓光標(biāo)移到下一個(gè)輸入框
<input onkeydown="if(event.keyCode==13)event.keyCode=9">
文本框的默認(rèn)值
<input type=text value="123" onfocus="alert(this.defaultValue)">
title換行
obj.title = "123 sdfs "
獲得時(shí)間所代表的微秒
var n1 = new Date("2004-10-10".replace(/-/g, "\/")).getTime()
窗口是否關(guān)閉
win.closed
checkbox扁平
<input type=checkbox style="position: absolute; clip:rect(5px 15px 15px 5px)"><br>
獲取選中內(nèi)容
document.selection.createRange().duplicate().text
自動(dòng)完成功能
<input type=text autocomplete=on>打開該功能
<input type=text autocomplete=off>關(guān)閉該功能
窗口最大化
