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?

这结合了罗伯的原始答案和皮劳2016年的更新

    var isOpera = !!window.opera || navigator.userAgent.indexOf(' OPR/') >= 0;
    // Opera 8.0+ (UA detection to detect Blink/v8-powered Opera)
var isFirefox = typeof InstallTrigger !== 'undefined';   // Firefox 1.0+
var isSafari = Object.prototype.toString.call(window.HTMLElement).indexOf('Constructor') > 0;
    // At least Safari 3+: "[object HTMLElementConstructor]"
var isChrome = !!window.chrome && !isOpera;              // Chrome 1+
var isIE = /*@cc_on!@*/false || !!document.documentMode;
// Edge 20+
var isEdge = !isIE && !!window.StyleMedia;
// Chrome 1+
var output = 'Detecting browsers by ducktyping:<hr>';
output += 'isFirefox: ' + isFirefox + '<br>';
output += 'isChrome: ' + isChrome + '<br>';
output += 'isSafari: ' + isSafari + '<br>';
output += 'isOpera: ' + isOpera + '<br>';
output += 'isIE: ' + isIE + '<br>';
output += 'isIE Edge: ' + isEdge + '<br>';
document.body.innerHTML = output;

var BrowserType; (function (BrowserType) { BrowserType["OPERA"] = "Opera"; BrowserType["OPERA2"] = "OPR"; BrowserType["EDGE"] = "Edg"; BrowserType["CHROME"] = "Chrome"; BrowserType["SAFARI"] = "Safari"; BrowserType["FIREFOX"] = "Firefox"; BrowserType["UNKNOWN"] = "unknown"; })(BrowserType || (BrowserType = {})); const detectBrowser = () => { return Object.values(BrowserType).find((browser) => navigator.userAgent.indexOf(browser) != -1); }; console.log(detectBrowser());

简单的一行JavaScript代码会告诉你浏览器的名称:

function GetBrowser()
{
    return  navigator ? navigator.userAgent.toLowerCase() : "other";
}

不知道它是否对任何人都有用，但这里有一个变体，会让TypeScript高兴:

export function getBrowser() {

 // Opera 8.0+
    if ((!!window["opr"] && !!["opr"]["addons"]) || !!window["opera"] || navigator.userAgent.indexOf(' OPR/') >= 0) {
        return 'opera';
    }

    // Firefox 1.0+
    if (typeof window["InstallTrigger"] !== 'undefined') {
        return 'firefox';
    }

    // Safari 3.0+ "[object HTMLElementConstructor]" 
    if (/constructor/i.test(window["HTMLElement"]) || (function(p) { return p.toString() === "[object SafariRemoteNotification]"; })(!window['safari'] || (typeof window["safari"] !== 'undefined' && window["safari"].pushNotification))) {
        return 'safari';
    }

    // Internet Explorer 6-11
    if (/*@cc_on!@*/false || !!document["documentMode"]) {
        return 'ie';
    }

    // Edge 20+
    if (!(/*@cc_on!@*/false || !!document["documentMode"]) && !!window["StyleMedia"]) {
        return 'edge';
    }

    // Chrome 1+
    if (!!window["chrome"] && !!window["chrome"].webstore) {
        return 'chrome';
    }

    // Blink engine detection
    if (((!!window["chrome"] && !!window["chrome"].webstore) || ((!!window["opr"] && !!["opr"]["addons"]) || !!window["opera"] || navigator.userAgent.indexOf(' OPR/') >= 0)) && !!window["CSS"]) {
        return 'blink';
    }
}

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();

const isChrome = /Chrome/.test(navigator.userAgent)
const isFirefox = /Firefox/.test(navigator.userAgent)
