document.getElementsByName("r1");
document.getElementById(id);
定時timer=setInterval('scrollwindow()',delay);
clearInterval(timer);
UNCODE編碼escape() ,unescape

自動刷新
快速轉(zhuǎn)到位置obj.scrollIntoView(true)
錨
anchors
網(wǎng)頁傳遞參數(shù)location.search();
可編輯obj.contenteditable=true
執(zhí)行菜單命令
obj.execCommand
雙字節(jié)字符

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
獲得style內(nèi)容obj.style.cssText
HTML標(biāo)簽
document.documentElement.innerHTML
第一個style標(biāo)簽
document.styleSheets[0]
style標(biāo)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。word
上一網(wǎng)頁源
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
禁止選取
禁止粘貼
地址欄圖標(biāo)
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(biāo)
查看源碼
關(guān)閉輸入法
自動全選
ENTER鍵可以讓光標(biāo)移到下一個輸入框
文本框的默認(rèn)值
title換行obj.title = "123 sdfs "
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(guān)閉win.closed
checkbox扁平
獲取選中內(nèi)容document.selection.createRange().duplicate().text
自動完成功能打開該功能
關(guān)閉該功能
窗口最大化
無關(guān)閉按鈕IEwindow.open("aa.htm", "meizz", "fullscreen=7");
統(tǒng)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

//過濾數(shù)字
//特殊用途

//正則匹配
匹配中文字符的正則表達式：?[\u4e00-\u9fa5]
匹配雙字節(jié)字符(包括漢字在內(nèi))：[^\x00-\xff]
匹配空行的正則表達式：\n[\s|?]*\r
匹配HTML標(biāo)記的正則表達式：/.*|/
匹配首尾空格的正則表達式：(^\s*)|(\s*$)(像vbscript那樣的trim函數(shù))
匹配Email地址的正則表達式：\w+([-+.]\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*
匹配網(wǎng)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(wǎng)頁表單里的文本框輸入內(nèi)容：
用正則表達式限制只能輸入中文：οnkeyup="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：?οnkeyup="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(shù)字：οnkeyup="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(shù)字和英文：οnkeyup="value=value.replace(/[\W]/g,'')?"onbeforepaste="clipboardData.setData('text',clipboardData.getData('text').replace(/[^\d]/g,''))"
