//取得用户代理字符串 并全部小写。 var ua = navigator.userAgent.toLowerCase(); document.write(ua);
在上篇文章给大家介绍了基于javascript代码检测访问网页的浏览器呈现引擎、平台、Windows操作系统、移动设备和游戏系统
,感兴趣的朋友可以点击全文了解详情。
1、识别呈现引擎
引擎主要包含四种:IE、Gecko、WebKit、Opera
2、识别浏览器
主流浏览器包含四种:IE、Chrome、Firefox、Opera
3、识别平台
主流平台包含三类:Windows、Mac、Unix
4、识别Windows操作系统
Windows操作系统包含:Windows 98、Window NT、Window XP、Window Vista、Windows 7…
5、识别移动设备
主流的移动设备包含三类:iPhone、iPod、Anroid、Nokia
6、识别游戏系统。
主流的游戏系统包含两类:Wii、PS3。
网上发现的比较简单的区分代码:
JavaScript
var ua = navigator.userAgent.toLowerCase(); var isStrict = document.compatMode == "CSS1Compat" isOpera = ua.indexOf("opera") > -1 isChrome = ua.indexOf("chrome") > -1 isSafari = !isChrome && (/webkit|khtml/).test(ua) isSafari3 = isSafari && ua.indexOf('webkit/5') != -1 isIE = !isOpera && ua.indexOf("msie") > -1 isIE7 = !isOpera && ua.indexOf("msie 7") > -1 isIE8 = !isOpera && ua.indexOf("msie 8") > -1 isGecko = !isSafari && !isChrome && ua.indexOf("gecko") > -1 isGecko3 = isGecko && ua.indexOf("rv:1.9") > -1 isBorderBox = isIE && !isStrict isWin7 = ua.indexOf("nt 6.1") > -1 isVista = ua.indexOf("nt 6.0") > -1 isWin2003 = ua.indexOf("nt 5.2") > -1 isWinXp = ua.indexOf("nt 5.1") > -1 isWin2000 = ua.indexOf("nt 5.0") > -1 isWindows = (ua.indexOf("windows") != -1 || ua.indexOf("win32") != -1) isMac = (ua.indexOf("macintosh") != -1 || ua.indexOf("mac os x") != -1) isAir = (ua.indexOf("adobeair") != -1) isLinux = (ua.indexOf("linux") != -1) var sys = ""; var broser = ""; if(isIE){ broser = "IE 6"; }else if(isIE7){ broser = "IE 7"; }else if(isIE8){ broser = "IE 8"; }else if(isOpera){ broser = "Opera"; }else if(isChrome){ broser = "Chrome"; }else if(isSafari){ broser = "Safari"; }else if(isSafari3){ broser = "Safari3"; }else{ broser = "Unknow"; } if(isWin7){ sys = "Windows 7"; }else if(isVista){ sys = "Vista"; }else if(isWinXp){ sys = "Windows xp"; }else if(isWin2003){ sys = "Windows 2003"; }else if(isWin2000){ sys = "Windows 2000"; }else if(isWindows){ sys = "Windows"; }else if(isMac){ sys = "Macintosh"; }else if(isAir){ sys = "Adobeair"; }else if(isLinux){ sys = "Linux"; }else{ sys = "Unknow"; } document.write(ua); alert(sys + ":" + broser);
比较全面的区分代码:
JavaScript
var client = function(){ //呈现引擎 var engine = { ie : 0, gecko : 0, webkit : 0, khtml : 0, opera : 0, //完整的版本号 ver : null }; //浏览器 var browser = { //主要浏览器 ie : 0, firefox : 0, konq : 0, opera : 0, chrome : 0, safari : 0, //具体的版本号 ver : null }; //平台、设备和操作系统 var system ={ win : false, mac : false, xll : false, //移动设备 iphone : false, ipod : false, nokiaN : false, winMobile : false, macMobile : false, //游戏设备 wii : false, ps : false }; //检测呈现引擎和浏览器 var ua = navigator.userAgent; if (window.opera){ engine.ver = browser.ver = window.opera.version(); engine.opera = browser.opera = parseFloat(engine.ver); } else if (/AppleWebKit\/(\S+)/.test(ua)){ engine.ver = RegExp["$1"]; engine.webkit = parseFloat(engine.ver); //确定是Chrome还是Safari if (/Chrome\/(\S+)/.test(ua)){ browser.ver = RegExp["$1"]; browser.chrome = parseFloat(browser.ver); } else if (/Version\/(\S+)/.test(ua)){ browser.ver = RegExp["$1"]; browser.safari = parseFloat(browser.ver); } else { //近似地确定版本号 var safariVersion = 1; if(engine.webkit < 100){ safariVersion = 1; } else if (engine.webkit < 312){ safariVersion = 1.2; } else if (engine.webkit < 412){ safariVersion = 1.3; } else { safariVersion = 2; } browser.safari = browser.ver = safariVersion; } } else if (/KHTML\/(\S+)/.test(ua) || /Konquersor\/([^;]+)/.test(ua)){ engine.ver = browser.ver = RegExp["$1"]; engine.khtml = browser.kong = paresFloat(engine.ver); } else if (/rv:([^\)]+)\) Gecko\/\d{8}/.test(ua)){ engine.ver = RegExp["$1"] engine.gecko = parseFloat(engine.ver); //确定是不是Firefox if (/Firefox\/(\S+)/.test(ua)){ browser.ver = RegExp["$1"]; browser.firefox = pareseFloat(browser.ver); } } else if(/MSIE([^;]+)/.test(ua)){ browser.ver = RegExp["$1"]; browser.firefox = parseFloat(browser.ver); } //检测浏览器 browser.ie = engine.ie; browser.opera = engine.opera; //检测平台 var p = navigator.platform; system.win = p.indexOf("Win") == 0; system.mac = p.indexOf("Mac") == 0; system.x11 = (p == "X11") || (p.indexOf("Linux") == 0); //检测Windows操作系统 if (system.win){ if (/Win(?:doms)?([^do]{2})\s?(\d+\.\d+)?/.test(ua)){ if (RegExp["$1"] == "NT"){ switch(RegExp["$2"]){ case "5.0": system.win = "2000"; break; case "5.1": system.win = "XP"; break; case "6.0": system.win = "Vista"; break; default : system.win = "NT"; break; } } else if (RegExp["$1"]){ system.win = "ME"; } else { system.win = RegExp["$1"]; } } } //移动设备 system.iphone = ua.indexOf("iPhone") > -1; system.ipod = ua.indexOf("iPod") > -1; system.nokiaN = ua.indexOf("NokiaN") > -1; system.winMobile = (system.win == "CE"); system.macMobile = (system.iphone || system.ipod); //游戏系统 system.wii = ua.indexOf("Wii") > -1; system.ps = /playstation/i.test(ua); //返回这些对象 return { engine: engine, browser: browser, system: system }; }()

Detailed explanation of JavaScript string replacement method and FAQ This article will explore two ways to replace string characters in JavaScript: internal JavaScript code and internal HTML for web pages. Replace string inside JavaScript code The most direct way is to use the replace() method: str = str.replace("find","replace"); This method replaces only the first match. To replace all matches, use a regular expression and add the global flag g: str = str.replace(/fi

Core points This in JavaScript usually refers to an object that "owns" the method, but it depends on how the function is called. When there is no current object, this refers to the global object. In a web browser, it is represented by window. When calling a function, this maintains the global object; but when calling an object constructor or any of its methods, this refers to an instance of the object. You can change the context of this using methods such as call(), apply(), and bind(). These methods call the function using the given this value and parameters. JavaScript is an excellent programming language. A few years ago, this sentence was
