At work, you need to use JS to get the name and version number of the currently used browser. A lot of information on the Internet has a keyword called navigator.appName, but there are only two browser names obtained by this method, either IE. Or Netscap, which can be used to determine whether IE is used, but I want to get the specific browser product name such as Firefox, Chrome, etc.

Copy code The code is as follows:

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), // Cheetah Browser

              isUc: /ucweb/.test(UserAgent), // UC Browser

               is360: /360se/.test(UserAgent), // 360 Browser

                isBaidu: /bidubrowser/.test(UserAgent), // Baidu Browser

              isSougou: /metasr/.test(UserAgent), // Sogou Browser

               isChrome: /chrome/.test(UserAgent.substr(-33, 6)), // Chrome browser

               isFirefox: /firefox/.test(UserAgent), // Firefox

              isOpera: /opera/.test(UserAgent), // Opera browser

                 isSafire: /safari/.test(UserAgent) && !/chrome/.test(UserAgent), // safire browser

              isQQ:/qqbrowser/.test(UserAgent)//qq browser

        };

})()
