javascript 获取浏览器版本
工作中需要通过JS去获取当前使用的浏览器的名字以及版本号,网上大堆资料都有一个关键词是 navigator.appName,但是这个方法获取的浏览器的名字只有两种要么是IE要么就是Netscap,倒是可以用来判断是否使用了IE,但是我想获取具体的浏览器产品名字比如 Firefox,Chrome等。
代码如下:
function BroswerUtil() { } BroswerUtil.prototype = { getBrowserVersion: function () { var agent = navigator.userAgent.toLowerCase(); var arr = []; var Browser = ""; var Bversion = ""; var verinNum = ""; //IE if (agent.indexOf("msie") > 0) { var regStr_ie = /msie [\d.]+;/gi; Browser = "IE"; Bversion = "" + agent.match(regStr_ie) } //firefox else if (agent.indexOf("firefox") > 0) { var regStr_ff = /firefox\/[\d.]+/gi; Browser = "firefox"; Bversion = "" + agent.match(regStr_ff); } //Chrome else if (agent.indexOf("chrome") > 0) { var regStr_chrome = /chrome\/[\d.]+/gi; Browser = "chrome"; Bversion = "" + agent.match(regStr_chrome); } //Safari else if (agent.indexOf("safari") > 0 && agent.indexOf("chrome") < 0) { var regStr_saf = /version\/[\d.]+/gi; Browser = "safari"; Bversion = "" + agent.match(regStr_saf); } //Opera else if (agent.indexOf("opera") >= 0) { var regStr_opera = /version\/[\d.]+/gi; Browser = "opera"; Bversion = "" + agent.match(regStr_opera); } else { var browser = navigator.appName; if (browser == "Netscape") { var version = agent.split(";"); var trim_Version = version[7].replace(/[ ]/g, ""); var rvStr = trim_Version.match(/[\d\.]/g).toString(); var rv = rvStr.replace(/[,]/g, ""); Bversion = rv; Browser = "IE" } } verinNum = (Bversion + "").replace(/[^0-9.]/ig, ""); arr.push(Browser); arr.push(verinNum); return arr; }, WB: (function () { var UserAgent = navigator.userAgent.toLowerCase(); alert(UserAgent) return { isIE6: /msie 6.0/.test(UserAgent), // IE6 isIE7: /msie 7.0/.test(UserAgent), // IE7 isIE8: /msie 8.0/.test(UserAgent), // IE8 isIE9: /msie 9.0/.test(UserAgent), // IE9 isIE10: /msie 10.0/.test(UserAgent), // IE10 isIE11: /msie 11.0/.test(UserAgent), // IE11 isLB: /lbbrowser/.test(UserAgent), // 猎豹浏览器 isUc: /ucweb/.test(UserAgent), // UC浏览器 is360: /360se/.test(UserAgent), // 360浏览器 isBaidu: /bidubrowser/.test(UserAgent), // 百度浏览器 isSougou: /metasr/.test(UserAgent), // 搜狗浏览器 isChrome: /chrome/.test(UserAgent.substr(-33, 6)), // Chrome浏览器 isFirefox: /firefox/.test(UserAgent), // 火狐浏览器 isOpera: /opera/.test(UserAgent), // Opera浏览器 isSafire: /safari/.test(UserAgent) && !/chrome/.test(UserAgent), // safire浏览器 isQQ:/qqbrowser/.test(UserAgent)//qq浏览器 }; })() }
