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?
当前回答
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';
}
}
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());
这是我定制的解决方案。
const inBrowser = typeof window !== 'undefined'
const UA = inBrowser && window.navigator.userAgent.toLowerCase()
const isIE =
UA && /; msie|trident/i.test(UA) && !/ucbrowser/i.test(UA).test(UA)
const isEdge = UA && /edg/i.test(UA)
const isAndroid = UA && UA.indexOf('android') > 0
const isIOS = UA && /iphone|ipad|ipod|ios/i.test(UA)
const isChrome =
UA &&
/chrome|crios/i.test(UA) &&
!/opr|opera|chromium|edg|ucbrowser|googlebot/i.test(UA)
const isGoogleBot = UA && /googlebot/i.test(UA)
const isChromium = UA && /chromium/i.test(UA)
const isUcBrowser = UA && /ucbrowser/i.test(UA)
const isSafari =
UA &&
/safari/i.test(UA) &&
!/chromium|edg|ucbrowser|chrome|crios|opr|opera|fxios|firefox/i.test(UA)
const isFirefox = UA && /firefox|fxios/i.test(UA) && !/seamonkey/i.test(UA)
const isOpera = UA && /opr|opera/i.test(UA)
const isMobile =
/\b(BlackBerry|webOS|iPhone|IEMobile)\b/i.test(UA) ||
/\b(Android|Windows Phone|iPad|iPod)\b/i.test(UA)
const isSamsung = UA && /samsungbrowser/i.test(UA)
const isIPad = UA && /ipad/.test(UA)
const isIPhone = UA && /iphone/.test(UA)
const isIPod = UA && /ipod/.test(UA)
console.log({
UA,
isAndroid,
isChrome,
isChromium,
isEdge,
isFirefox,
isGoogleBot,
isIE,
isMobile,
isIOS,
isIPad,
isIPhone,
isIPod,
isOpera,
isSafari,
isSamsung,
isUcBrowser,
}
}
您可以尝试以下方法检查浏览器版本。
<!DOCTYPE html>
<html>
<body>
<p>What is the name(s) of your browser?</p>
<button onclick="myFunction()">Try it</button>
<p id="demo"></p>
<script>
function myFunction() {
if((navigator.userAgent.indexOf("Opera") || navigator.userAgent.indexOf('OPR')) != -1 )
{
alert('Opera');
}
else if(navigator.userAgent.indexOf("Edg") != -1 )
{
alert('Edge');
}
else if(navigator.userAgent.indexOf("Chrome") != -1 )
{
alert('Chrome');
}
else if(navigator.userAgent.indexOf("Safari") != -1)
{
alert('Safari');
}
else if(navigator.userAgent.indexOf("Firefox") != -1 )
{
alert('Firefox');
}
else if((navigator.userAgent.indexOf("MSIE") != -1 ) || (!!document.documentMode == true )) //IF IE > 10
{
alert('IE');
}
else
{
alert('unknown');
}
}
</script>
</body>
</html>
如果你只需要知道IE浏览器版本，那么你可以遵循下面的代码。这段代码适用于IE6到IE11版本
<!DOCTYPE html>
<html>
<body>
<p>Click on Try button to check IE Browser version.</p>
<button onclick="getInternetExplorerVersion()">Try it</button>
<p id="demo"></p>
<script>
function getInternetExplorerVersion() {
var ua = window.navigator.userAgent;
var msie = ua.indexOf("MSIE ");
var rv = -1;
if (msie > 0 || !!navigator.userAgent.match(/Trident.*rv\:11\./)) // If Internet Explorer, return version number
{
if (isNaN(parseInt(ua.substring(msie + 5, ua.indexOf(".", msie))))) {
//For IE 11 >
if (navigator.appName == 'Netscape') {
var ua = navigator.userAgent;
var re = new RegExp("Trident/.*rv:([0-9]{1,}[\.0-9]{0,})");
if (re.exec(ua) != null) {
rv = parseFloat(RegExp.$1);
alert(rv);
}
}
else {
alert('otherbrowser');
}
}
else {
//For < IE11
alert(parseInt(ua.substring(msie + 5, ua.indexOf(".", msie))));
}
return false;
}}
</script>
</body>
</html>
短变体(更新2020年7月10日移动浏览器检测修复)
var browser = (function() { var test = function(regexp) {return regexp.test(window.navigator.userAgent)} switch (true) { case test(/edg/i): return "Microsoft Edge"; case test(/trident/i): return "Microsoft Internet Explorer"; case test(/firefox|fxios/i): return "Mozilla Firefox"; case test(/opr\//i): return "Opera"; case test(/ucbrowser/i): return "UC Browser"; case test(/samsungbrowser/i): return "Samsung Browser"; case test(/chrome|chromium|crios/i): return "Google Chrome"; case test(/safari/i): return "Apple Safari"; default: return "Other"; } })(); console.log(browser)
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();
