如何检测Safari, Chrome, IE, Firefox和Opera浏览器?

我有5个插件/扩展Firefox, Chrome, Internet Explorer(IE)， Opera和Safari。

我如何正确识别用户浏览器和重定向(一旦安装按钮已被点击)下载相应的插件?

短变体(更新2020年7月10日移动浏览器检测修复)

打字文件版本:

export enum BROWSER_ENUM {
  EDGE ,
  INTERNET_EXPLORER ,
  FIRE_FOX ,
  OPERA ,
  UC_BROWSER ,
  SAMSUNG_BROWSER ,
  CHROME ,
  SAFARI ,
  UNKNOWN ,
}

const testUserAgent = (regexp: RegExp): boolean => regexp.test(window.navigator.userAgent);

function detectBrowser(): BROWSER_ENUM {
  switch (true) {
    case testUserAgent(/edg/i): return BROWSER_ENUM.EDGE;
    case testUserAgent(/trident/i): return BROWSER_ENUM.INTERNET_EXPLORER;
    case testUserAgent(/firefox|fxios/i): return BROWSER_ENUM.FIRE_FOX;
    case testUserAgent(/opr\//i): return BROWSER_ENUM.OPERA;
    case testUserAgent(/ucbrowser/i): return BROWSER_ENUM.UC_BROWSER;
    case testUserAgent(/samsungbrowser/i): return BROWSER_ENUM.SAMSUNG_BROWSER;
    case testUserAgent(/chrome|chromium|crios/i): return BROWSER_ENUM.CHROME;
    case testUserAgent(/safari/i): return BROWSER_ENUM.SAFARI;
    default: return BROWSER_ENUM.UNKNOWN;
  }
}

export const BROWSER: BROWSER_ENUM = detectBrowser();

export const IS_FIREFOX = BROWSER === BROWSER_ENUM.FIRE_FOX;

函数式算法，只是为了好玩:

 const BROWSER =  Object.entries({
     "Microsoft Edge": /edg/i,
     "Microsoft Internet Explorer": /trident/i,
     "Mozilla Firefox": /firefox|fxios/i,
     "Opera": /opr\//i,
     "UC Browser": /ucbrowser/i,
     "Samsung Browser": /samsungbrowser/i,
     "Google Chrome": /chrome|chromium|crios/i,
     "Apple Safari": /safari/i,
     "Unknown": /.+/i,
 }).find(([, value]) => value.test(window.navigator.userAgent)).pop();

var BrowserDetect = {
        init: function () {
            this.browser = this.searchString(this.dataBrowser) || "Other";
            this.version = this.searchVersion(navigator.userAgent) || this.searchVersion(navigator.appVersion) || "Unknown";
        },
        searchString: function (data) {
            for (var i = 0; i < data.length; i++) {
                var dataString = data[i].string;
                this.versionSearchString = data[i].subString;

                if (dataString.indexOf(data[i].subString) !== -1) {
                    return data[i].identity;
                }
            }
        },
        searchVersion: function (dataString) {
            var index = dataString.indexOf(this.versionSearchString);
            if (index === -1) {
                return;
            }

            var rv = dataString.indexOf("rv:");
            if (this.versionSearchString === "Trident" && rv !== -1) {
                return parseFloat(dataString.substring(rv + 3));
            } else {
                return parseFloat(dataString.substring(index + this.versionSearchString.length + 1));
            }
        },

        dataBrowser: [
            {string: navigator.userAgent, subString: "Edge", identity: "MS Edge"},
            {string: navigator.userAgent, subString: "MSIE", identity: "Explorer"},
            {string: navigator.userAgent, subString: "Trident", identity: "Explorer"},
            {string: navigator.userAgent, subString: "Firefox", identity: "Firefox"},
            {string: navigator.userAgent, subString: "Opera", identity: "Opera"},  
            {string: navigator.userAgent, subString: "OPR", identity: "Opera"},  

            {string: navigator.userAgent, subString: "Chrome", identity: "Chrome"}, 
            {string: navigator.userAgent, subString: "Safari", identity: "Safari"}       
        ]
    };

    BrowserDetect.init();


    var bv= BrowserDetect.browser;
    if( bv == "Chrome"){
        $("body").addClass("chrome");
    }
    else if(bv == "MS Edge"){
     $("body").addClass("edge");
    }
    else if(bv == "Explorer"){
     $("body").addClass("ie");
    }
    else if(bv == "Firefox"){
     $("body").addClass("Firefox");
    }


$(".relative").click(function(){
$(".oc").toggle('slide', { direction: 'left', mode: 'show' }, 500);
$(".oc1").css({
   'width' : '100%',
   'margin-left' : '0px',
   });
});

import getAgent, { getAccurateAgent } from "@egjs/agent";

const agent = getAgent();
getAccurateAgent().then((accurate_agent)=>{
    console.log(agent,'accurate.');
})
console.log(agent);

如果您需要知道某个特定浏览器的数字版本是什么，可以使用下面的代码片段。目前它会告诉你Chrome/Chromium/Firefox的版本:

var match = $window.navigator.userAgent.match(/(?:Chrom(?:e|ium)|Firefox)\/([0-9]+)\./);
var ver = match ? parseInt(match[1], 10) : 0;

此方法目前对检测所有浏览器有效。我引用vue-element-admin模板

 export function fnBrowserDetect() {
      var browserName = (function(agent) {
        switch (true) {
          case agent.indexOf('edge') > -1: return 'MS Edge'
          case agent.indexOf('edg/') > -1: return 'Edge (chromium based)'
          case agent.indexOf('opr') > -1 && !!window.opr: return 'Opera'
          case agent.indexOf('chrome') > -1 && !!window.chrome: return 'Chrome'
          case agent.indexOf('trident') > -1: return 'MS IE'
          case agent.indexOf('firefox') > -1: return 'Mozilla Firefox'
          case agent.indexOf('safari') > -1: return 'Safari'
          default: return 'other'
        }
      })(window.navigator.userAgent.toLowerCase())
      return browserName.toLowerCase()
    }
