本文主要为大家带来一篇javascript浏览器用户代理检测脚本实现方法。小编觉得挺不错的,现在就分享给大家,也给大家做个参考。一起跟随小编过来看看吧,希望能帮助到大家。
以下是完整的用户代理字符串检测脚本,包括检测呈现引擎、平台、Windows操作系统、移动设备和游戏系统。
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, safari: 0, konq: 0, opera: 0, chrome: 0, // 具体的版本号 ver: null }; // 平台、设备和操作系统 var system = { win: false, mac: false, x11: false, // 移动设备 iphone: false, ipod: false, ipad: false, ios: false, android: false, nokiaN: false, winMobile: false, // 游戏系统 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Chroeme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) || /Konqueror\/([^;]+)/.test(ua)){ engine.ver = browser.ver = RegExp["$1"]; engine.khtml = browser.konq = parseFloat(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 = parseFloat(browser.ver); } } else if (/MSIE ([^;]+)/.test(ua)){ engine.ver = browser.ver = RegExp["$1"]; engine.ie = browser.ie = parseFloat(engine.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(?:dows )?([^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; case "6.1": system.win = "7"; break; default: system.win = "NT"; break; } } else if(RegExp["$1"] == "9x"){ 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.ipad = ua.indexOf("iPad") >-1; system.nokiaN = ua.indexOf("NokiaN") > -1; // windows mobile if(system.win == "CE"){ system.winMobile = system.win; } else if(system.win == "Ph" ){ if(/Windows Phone OS (\d+.\d+)/.test(ua)){ system.win = "Phone"; system.winMobile = parseFloat(RegExp["$1"]); } } // 检测IOS版本 if(system.mac && ua.indexOf("Mobile")> -1){ if(/CPU (?:Phone )?OS (\d+_\d+)/.test(ua)){ system.ios = parseFloat(RegExp.$1.replace("_",".")); } else{ system.ios = 2; // 不能真正检测出来,所以只能猜测 } } // 检测Android版本 if(/Android (\d+\.\d+)/.test(ua)){ system.android = parseFloat(RegExp.$1); } // 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 }; // console.log(engine); // console.log(browser); // console.log(system); }();
