我一直在寻找可以让我检测访问该网站的用户是否拥有 Firefox 3 或 4 的代码。我发现的只是检测浏览器类型而不是版本的代码。
如何检测这样的浏览器版本?
您可以查看浏览器所说的内容,并使用该信息记录或测试多个浏览器。
navigator.sayswho= (function(){ var ua= navigator.userAgent; var tem; var M= ua.match(/(opera|chrome|safari|firefox|msie|trident(?=\/))\/?\ s*(\d+)/i) || []; if(/trident/i.test(M[1])){ tem= /\brv[ :]+(\d+)/g.exec(ua) || []; return 'IE '+(tem[1] || ''); } if(M[1]=== 'Chrome'){ tem= ua.match(/\b(OPR|Edge) \/(\d+)/); if(tem!= null) return tem.slice(1).join('').replace('OPR', 'Opera'); } M= M[2]? [ M[1], M[2]]: [navigator.appName, navigator.appVersion, '-?']; if((tem= ua.match(/version\/(\d+)/i))!= null ) M.splice(1, 1, tem[1]); return M.join(' '); })(); console.log(navigator.sayswho); // 输出:`Chrome 62`
这是对 Kennebec 答案的改进。
function get_browser() { var ua=navigator.userAgent,tem,M=ua.match(/(opera|chrome|safari|firefox|msie|trident(?=\/))\/?\s*(\d+) /i) || []; if(/trident/i.test(M[1])){ tem=/\brv[ :]+(\d+)/g.exec(ua) || [];返回 {name:'IE',version:(tem[1]||'')}; } if(M[1]==='Chrome'){ tem=ua.match(/\bOPR|Edge\/(\d+)/) if(tem!=null) {return {name:'Opera',版本:tem[1]};} } M=M[2]? [M[1], M[2]]: [navigator.appName, navigator.appVersion, '-?']; if((tem=ua.match(/version\/(\d+)/i))!=null) {M.splice(1,1,tem[1]);} return { name: M[0],版本:M[1] }; } var browser=get_browser(); // browser.name = 'Chrome' // browser.version = '40' console.log(browser);
这样你就可以保护自己免受代码的晦涩难懂。

这结合了 kennebec (K) 的答案和 Hermann Ingjaldsson 的 (H) 答案:
维护原始答案的最小代码。 (K)
适用于 Microsoft Edge (K)
扩展导航器对象,而不是创建新的变量/对象。 (K)
将浏览器版本和名称分隔为独立的子对象。 (H)
navigator.browserSpecs = (function(){ var ua = navigator.userAgent, tem, M = ua.match(/(opera|chrome|safari|firefox|msie|trident(?=\/))\/?\s* (\d+)/i) || []; if(/trident/i.test(M[1])){ tem = /\brv[ :]+(\d+)/g.exec(ua) || []; return {name:'IE',version:(tem[1] || '')}; } if(M[1]=== 'Chrome'){ tem = ua.match(/\b( OPR|Edge)\/(\d+)/); if(tem != null) return {name:tem[1].replace('OPR', 'Opera'),version:tem[2]}; } M = M[2]? [M[1], M[2]]: [navigator.appName, navigator.appVersion, '-?']; if((tem = ua.match(/version\/(\d+) /i))!= null) M.splice(1, 1, tem[1]); return {name:M[0], version:M[1]}; })(); console.log(navigator.browserSpecs); //Object { name: "Firefox", version: "42" } if (navigator.browserSpecs.name == 'Firefox') { // 为 Firefox 做点什么。 if (navigator.browserSpecs.version > 42) { // 为大于 42 的 Firefox 版本做一些事情。 } } else { // 为所有其他浏览器做一些事情。 }
bowser JavaScript 库提供此功能。
if (bowser.msie && bowser.version <= 6) {
alert('Hello China');
}
它似乎维护得很好。
使用这个:http://www.quirksmode.org/js/detect.html
alert(BrowserDetect.browser); // will say "Firefox"
alert(BrowserDetect.version); // will say "3" or "4"
我一直在为自己寻找解决方案,因为 jQuery 1.9.1 及更高版本已删除 $.browser
功能。我想出了这个对我有用的小功能。它确实需要一个全局变量(我叫我的_browser)来检查它是哪个浏览器。我写了一个 jsfiddle 来说明它是如何使用的,当然它可以通过为 _browser.foo 添加一个测试来扩展到其他浏览器,其中 foo 是浏览器的名称。我只做了流行的。
_浏览器 = {};函数detectBrowser() { var uagent = navigator.userAgent.toLowerCase(), match = ''; _browser.chrome = /webkit/.test(uagent) && /chrome/.test(uagent) && !/edge/.test(uagent); _browser.firefox = /mozilla/.test(uagent) && /firefox/.test(uagent); _browser.msie = /msie/.test(uagent) || /trident/.test(uagent) || /edge/.test(uagent); _browser.safari = /safari/.test(uagent) && /applewebkit/.test(uagent) && !/chrome/.test(uagent); _browser.opr = /mozilla/.test(uagent) && /applewebkit/.test(uagent) && /chrome/.test(uagent) && /safari/.test(uagent) && /opr/.test(uagent); _browser.version = ''; for (x in _browser) { if (_browser[x]) { match = uagent.match( new RegExp("(" + (x === "msie" ? "msie|edge" : x) + ")( | \/)([0-9]+)") ); if (match) { _browser.version = match[3]; } else { match = uagent.match(new RegExp("rv:([0-9]+)")); _browser.version = 匹配?匹配[1]:“”; } 休息; } } _browser.opera = _browser.opr;删除_browser.opr; } 检测浏览器(); console.log(_browser)
要检查当前浏览器是否是 Opera,你会这样做
if (_browser.opera) { // Opera specific code }
编辑 修复了格式,修复了 IE11 和 Opera/Chrome 的检测,从结果更改为 browserResult。现在 _browser
键的顺序无关紧要。更新了 jsFiddle 链接。
2015/08/11 编辑为 Internet Explorer 12 (EDGE) 添加了新的测试用例,修复了一个小的正则表达式问题。更新了 jsFiddle 链接。
function BrowserCheck()
{
var N= navigator.appName, ua= navigator.userAgent, tem;
var M= ua.match(/(opera|chrome|safari|firefox|msie|trident)\/?\s*(\.?\d+(\.\d+)*)/i);
if(M && (tem= ua.match(/version\/([\.\d]+)/i))!= null) {M[2]=tem[1];}
M= M? [M[1], M[2]]: [N, navigator.appVersion,'-?'];
return M;
}
这将返回一个数组,第一个元素是浏览器名称,第二个元素是字符串格式的完整版本号。
在纯 Javascript 中,您可以在 navigator.userAgent
上进行 RegExp 匹配以查找 Firefox 版本:
var uMatch = navigator.userAgent.match(/Firefox\/(.*)$/),
ffVersion;
if (uMatch && uMatch.length > 1) {
ffVersion = uMatch[1];
}
如果不是 Firefox 浏览器,ffVersion
将是 undefined
。
jQuery 可以很好地处理这个问题 (jQuery.browser)
var ua = $.browser;
if ( ua.mozilla && ua.version.slice(0,3) == "1.9" ) {
alert( "Do stuff for firefox 3" );
}
编辑:正如 Joshua 在下面的评论中所写,自 1.9 版起,jQuery 不再支持 jQuery.browser 属性(有关详细信息,请阅读 jQuery 1.9 release notes)。 jQuery 开发团队 recommends 使用更完整的方法,例如使用 Modernizr 库调整 UI。
这是 Fzs2 和 kennebec 对于 New Edge Chromium 的更新
function get_browser() { var ua=navigator.userAgent,tem,M=ua.match(/(opera|chrome|safari|firefox|msie|trident(?=\/))\/?\s*(\d+) /i) || []; if(/trident/i.test(M[1])){ tem=/\brv[ :]+(\d+)/g.exec(ua) || [];返回 {name:'IE',version:(tem[1]||'')}; } if(M[1]==='Chrome'){ tem=ua.match(/\bEdg\/(\d+)/) if(tem!=null) {return {name:'Edge(Chromium)' , version:tem[1]};} tem=ua.match(/\bOPR\/(\d+)/) if(tem!=null) {return {name:'Opera', version:tem[1]} ;} } M=M[2]? [M[1], M[2]]: [navigator.appName, navigator.appVersion, '-?']; if((tem=ua.match(/version\/(\d+)/i))!=null) {M.splice(1,1,tem[1]);} return { name: M[0],版本:M[1] }; } var browser=get_browser(); // browser.name = 'Edge(Chromium)' // browser.version = '86' console.log(browser);
查看 navigator.userAgent
- Firefox/xxx.xxx.xxx
在末尾指定。
<script type="text/javascript">
var version = navigator.appVersion;
alert(version);
</script>
我根据 Hermann Ingjaldsson 的回答编写了一个版本检测器,但更健壮,它返回一个包含名称/版本数据的对象。它涵盖了主要的浏览器,但我不关心过多的移动浏览器和次要浏览器:
function getBrowserData(nav) {
var data = {};
var ua = data.uaString = nav.userAgent;
var browserMatch = ua.match(/(opera|chrome|safari|firefox|msie|trident(?=\/))\/?\s*([\d\.]+)/i) || [];
if (browserMatch[1]) { browserMatch[1] = browserMatch[1].toLowerCase(); }
var operaMatch = browserMatch[1] === 'chrome';
if (operaMatch) { operaMatch = ua.match(/\bOPR\/([\d\.]+)/); }
if (/trident/i.test(browserMatch[1])) {
var msieMatch = /\brv[ :]+([\d\.]+)/g.exec(ua) || [];
data.name = 'msie';
data.version = msieMatch[1];
}
else if (operaMatch) {
data.name = 'opera';
data.version = operaMatch[1];
}
else if (browserMatch[1] === 'safari') {
var safariVersionMatch = ua.match(/version\/([\d\.]+)/i);
data.name = 'safari';
data.version = safariVersionMatch[1];
}
else {
data.name = browserMatch[1];
data.version = browserMatch[2];
}
var versionParts = [];
if (data.version) {
var versionPartsMatch = data.version.match(/(\d+)/g) || [];
for (var i=0; i < versionPartsMatch.length; i++) {
versionParts.push(versionPartsMatch[i]);
}
if (versionParts.length > 0) { data.majorVersion = versionParts[0]; }
}
data.name = data.name || '(unknown browser name)';
data.version = {
full: data.version || '(unknown full browser version)',
parts: versionParts,
major: versionParts.length > 0 ? versionParts[0] : '(unknown major browser version)'
};
return data;
};
然后可以像这样使用它:
var brData = getBrowserData(window.navigator || navigator);
console.log('name: ' + brData.name);
console.log('major version: ' + brData.version.major);
// etc.
var nVer = navigator.appVersion;
var nAgt = navigator.userAgent;
var browserName = navigator.appName;
var fullVersion = ''+parseFloat(navigator.appVersion);
var majorVersion = parseInt(navigator.appVersion,10);
var nameOffset,verOffset,ix;
// In Opera, the true version is after "Opera" or after "Version"
if ((verOffset=nAgt.indexOf("Opera"))!=-1) {
browserName = "Opera";
fullVersion = nAgt.substring(verOffset+6);
if ((verOffset=nAgt.indexOf("Version"))!=-1)
fullVersion = nAgt.substring(verOffset+8);
}
// In MSIE, the true version is after "MSIE" in userAgent
else if ((verOffset=nAgt.indexOf("MSIE"))!=-1) {
browserName = "Microsoft Internet Explorer";
fullVersion = nAgt.substring(verOffset+5);
}
// In Chrome, the true version is after "Chrome"
else if ((verOffset=nAgt.indexOf("Chrome"))!=-1) {
browserName = "Chrome";
fullVersion = nAgt.substring(verOffset+7);
}
// In Safari, the true version is after "Safari" or after "Version"
else if ((verOffset=nAgt.indexOf("Safari"))!=-1) {
browserName = "Safari";
fullVersion = nAgt.substring(verOffset+7);
if ((verOffset=nAgt.indexOf("Version"))!=-1)
fullVersion = nAgt.substring(verOffset+8);
}
// In Firefox, the true version is after "Firefox"
else if ((verOffset=nAgt.indexOf("Firefox"))!=-1) {
browserName = "Firefox";
fullVersion = nAgt.substring(verOffset+8);
}
// In most other browsers, "name/version" is at the end of userAgent
else if ( (nameOffset=nAgt.lastIndexOf(' ')+1) <
(verOffset=nAgt.lastIndexOf('/')) )
{
browserName = nAgt.substring(nameOffset,verOffset);
fullVersion = nAgt.substring(verOffset+1);
if (browserName.toLowerCase()==browserName.toUpperCase()) {
browserName = navigator.appName;
}
}
// trim the fullVersion string at semicolon/space if present
if ((ix=fullVersion.indexOf(";"))!=-1)
fullVersion=fullVersion.substring(0,ix);
if ((ix=fullVersion.indexOf(" "))!=-1)
fullVersion=fullVersion.substring(0,ix);
majorVersion = parseInt(''+fullVersion,10);
if (isNaN(majorVersion)) {
fullVersion = ''+parseFloat(navigator.appVersion);
majorVersion = parseInt(navigator.appVersion,10);
}
document.write(''

检测浏览器及其版本
此代码段基于来自 MDN 的文章。他们在其中简要提示了可用于检测浏览器名称的各种关键字。
https://i.stack.imgur.com/BUfGl.png
我做了一些更改来检测 Edge 和 UCBrowser 等浏览器
getBrowser = () => { const userAgent = navigator.userAgent;让浏览器=“未知”; // 检测浏览器名称 browser = (/ucbrowser/i).test(userAgent) ? 'UCBrowser' : 浏览器;浏览器 = (/edg/i).test(userAgent) ? “边缘”:浏览器;浏览器 = (/googlebot/i).test(userAgent) ? 'GoogleBot' : 浏览器;浏览器 = (/chromium/i).test(userAgent) ? “铬”:浏览器;浏览器 = (/firefox|fxios/i).test(userAgent) && !(/seamonkey/i).test(userAgent) ? 'Firefox' : 浏览器; browser = (/; msie|trident/i).test(userAgent) && !(/ucbrowser/i).test(userAgent) ? 'IE' : 浏览器; browser = (/chrome|crios/i).test(userAgent) && !(/opr|opera|chromium|edg|ucbrowser|googlebot/i).test(userAgent) ? 'Chrome' : 浏览器;; browser = (/safari/i).test(userAgent) && !(/chromium|edg|ucbrowser|chrome|crios|opr|opera|fxios|firefox/i).test(userAgent) ? 'Safari' : 浏览器;浏览器 = (/opr|opera/i).test(userAgent) ? 'Opera' : 浏览器; // 检测浏览器版本切换 (browser) { case 'UCBrowser': return `${browser}/${browserVersion(userAgent,/(ucbrowser)\/([\d\.]+)/i)}`;案例'Edge':返回`${browser}/${browserVersion(userAgent,/(edge|edga|edgios|edg)\/([\d\.]+)/i)}`;案例“GoogleBot”:返回 `${browser}/${browserVersion(userAgent,/(googlebot)\/([\d\.]+)/i)}`; case 'Chromium': return `${browser}/${browserVersion(userAgent,/(chromium)\/([\d\.]+)/i)}`; case 'Firefox': 返回 `${browser}/${browserVersion(userAgent,/(firefox|fxios)\/([\d\.]+)/i)}`;案例“Chrome”:返回 `${browser}/${browserVersion(userAgent,/(chrome|crios)\/([\d\.]+)/i)}`; case 'Safari': return `${browser}/${browserVersion(userAgent,/(safari)\/([\d\.]+)/i)}`; case 'Opera': return `${browser}/${browserVersion(userAgent,/(opera|opr)\/([\d\.]+)/i)}`; case 'IE': const version = browserVersion(userAgent,/(trident)\/([\d\.]+)/i); // IE 版本使用 trident 版本映射 // IE/8.0 = Trident/4.0, IE/9.0 = Trident/5.0 返回版本 ? `${browser}/${parseFloat(version) + 4.0}` : `${browser}/7.0`;默认值:返回“未知/0.0.0.0”; } } browserVersion = (userAgent,regex) => { return userAgent.match(regex) ? userAgent.match(regex)[2] : null; } console.log(getBrowser());
为此,您需要检查 navigator.appVersion 或 navigator.userAgent 的值尝试使用:
console.log(navigator.appVersion)
我在 ASP 代码中制作了一个脚本来检测浏览器、浏览器版本、操作系统和操作系统版本。我在 ASP 中这样做的原因是因为我想将数据存储在日志数据库中。所以我不得不检测浏览器服务器端。

添加我自己对赫尔曼答案的实现。我需要操作系统检测,因此已添加。还包括一些您可能需要 ES5 化的 ES6 代码(因为我们有一个转译器)。
detectClient() {
let nav = navigator.appVersion,

let agent = navigator.userAgent,
engine = agent.match(/(opera|chrome|safari|firefox|msie|trident(?=\/))\/?\s*(\d+)/i) || [],

if(engine[1] === 'Chrome'){
build = agent.match(/\bOPR\/(\d+)/);
if(build !== null) {
return {browser: 'Opera', version: build[1]};
}
}
engine = engine[2] ? [engine[1], engine[2]] : [navigator.appName, nav, '-?'];
if((build = agent.match(/version\/(\d+)/i)) !== null) {
engine.splice(1, 1, build[1]);
}
return {
browser: engine[0],

switch (true) {
case nav.indexOf('Win') > -1:

client.os = os;

返回:Object {browser: "Chrome", version: "50", os: "UNIX"}
我想分享我为必须解决的问题编写的这段代码。它在大多数主要浏览器中都经过了测试,对我来说就像一个魅力!
似乎这段代码与其他答案非常相似,但它进行了修改,以便我可以在 jquery 中使用它插入浏览器对象,这对我来说最近错过了,当然它是上述代码的组合,几乎没有改进我的部分:

var M = ua.match(/(opera|chrome|safari|firefox|msie|trident(?=\/))\/?\s*(\d+)/i) || [],

res;
if(/trident/i.test(M[1])){
tem = /\brv[ :]+(\d+)/g.exec(ua) || [];
res = 'IE ' + (tem[1] || '');
}
else if(M[1] === 'Chrome'){
tem = ua.match(/\b(OPR|Edge)\/(\d+)/);
if(tem != null)
res = tem.slice(1).join(' ').replace('OPR', 'Opera');
else
res = [M[1], M[2]];
}
else {
M = M[2]? [M[1], M[2]] : [navigator.appName, navigator.appVersion, '-?'];
if((tem = ua.match(/version\/(\d+)/i)) != null) M = M.splice(1, 1, tem[1]);
res = M;
}
res = typeof res === 'string'? res.split(' ') : res;
$.browser = {

console.log($.browser.name, $.browser.version, $.browser.msie);

navigator.sayswho= (function(){ var ua= navigator.userAgent, tem, M= ua.match(/(opera|chrome|safari|firefox|msie|trident(?=\/))\/?\s* (\d+)/i) || []; if(/trident/i.test(M[1])){ tem= /\brv[ :]+(\d+)/g.exec(ua) || []; return 'IE '+(tem[1] || ''); } if(M[1]=== 'Chrome'){ tem= ua.match(/\b(OPR|Edge)\/ (\d+)/); if(tem!= null) return tem.slice(1).join('').replace('OPR', 'Opera'); } M= M[2]? [M[ 1], M[2]]: [navigator.appName, navigator.appVersion, '-?']; if((tem= ua.match(/version\/(\d+)/i))!= null) M .splice(1, 1, tem[1]); return M.join(' '); })(); console.log(navigator.sayswho); // 输出:`Chrome 62`
我用它来获取实际浏览器版本的名称和编号(int):
function getInfoBrowser() { var ua = navigator.userAgent, tem, M = ua.match(/(opera|chrome|safari|firefox|msie|trident(?=\/))\/?\s*(\d+) /i) || []; if (/trident/i.test(M[1])) { tem = /\brv[ :]+(\d+)/g.exec(ua) || []; return { 名称:'Explorer',版本:parseInt((tem[1] || '')) }; } if (M[1] === 'Chrome') { tem = ua.match(/\b(OPR|Edge)\/(\d+)/); if (tem != null) { let app = tem.slice(1).toString().split(','); return { name: app[0].replace('OPR', 'Opera'), version: parseInt(app[1]) }; } } M = M[2] ? [M[1], M[2]] : [navigator.appName, navigator.appVersion, '-?']; if ((tem = ua.match(/version\/(\d+)/i)) != null) M.splice(1, 1, tem[1]);返回{名称:M[0],版本:parseInt(M[1])}; } function getBrowser(){ 让 info = getInfoBrowser(); $("#i-name").html(info.name); $("#i-version").html(info.version); }
这个跑进
铬合金 ;火狐;苹果浏览器 ; Internet Explorer (>= 9) ;歌剧;边缘
为了我。
对于任何使用 Angular 的 PWA 应用程序,您可以将代码放在 index.html 的正文部分中以检查是否支持浏览器 -
<body>
<div id="browser"></div>
<script>
var operabrowser = true;
operabrowser = (navigator.userAgent.indexOf('Opera Mini') > -1);
if (operabrowser) {
txt = "<p>Browser not supported use different browser...</p>";
document.getElementById("browser").innerHTML = txt;
}
</script>
</body>
在这里,这比@kennebec 片段具有更好的兼容性;将返回浏览器名称和版本(返回 72 而不是 72.0.3626.96)。
在 Safari、Chrome、Opera、Firefox、IE、Edge、UCBrowser 以及移动设备上进行了测试。
function browser() {
var userAgent = navigator.userAgent,
match = userAgent.match(/(opera|chrome|crios|safari|ucbrowser|firefox|msie|trident(?=\/))\/?\s*(\d+)/i) || [],
result = {},
tem;
if (/trident/i.test(match[1])) {
tem = /\brv[ :]+(\d+)/g.exec(userAgent) || [];
result.name = "Internet Explorer";
} else if (match[1] === "Chrome") {
tem = userAgent.match(/\b(OPR|Edge)\/(\d+)/);
if (tem && tem[1]) {
result.name = tem[0].indexOf("Edge") === 0 ? "Edge" : "Opera";
}
}
if (!result.name) {
tem = userAgent.match(/version\/(\d+)/i); // iOS support
result.name = match[0].replace(/\/.*/, "");
if (result.name.indexOf("MSIE") === 0) {
result.name = "Internet Explorer";
}
if (userAgent.match("CriOS")) {
result.name = "Chrome";
}
}
if (tem && tem.length) {
match[match.length - 1] = tem[tem.length - 1];
}
result.version = Number(match[match.length - 1]);
return result;
}
var ua = navigator.userAgent;
if (/Firefox\//.test(ua))
var Firefox = /Firefox\/([0-9\.A-z]+)/.exec(ua)[1];
我写这个是为了我的需要。
它获取信息,例如是否是移动设备或是否具有视网膜显示器
var nav = {
isMobile:function(){

isOpera: function() {
return navigator.userAgent.match(/Opera Mini/i);
},
isWindows: function() {
return navigator.userAgent.match(/IEMobile/i);

return false;

getIOSVersion:function(){

var OSVersion = navigator.appVersion.match(/OS (\d+_\d+)/i);
OSVersion = OSVersion[1] ? +OSVersion[1].replace('_', '.') : 0;
return OSVersion;
}
else
return false;
},
isStandAlone:function(){
if(_.is(navigator.standalone))
return navigator.standalone;
return false;
},
isChrome:function(){

属性来返回正确的浏览器版本。已弃用
我根据我在其他帖子中找到的内容使用了这段 javascript 代码。
var browserHelper = function () { var self = {}; /// IE 6+ self.isIEBrowser = function () { return /*@cc_on!@*/false || !!document.documentMode; }; /// Opera 8.0+ self.isOperaBrowser = function () { return (!!window.opr && !!opr.addons) || !!window.opera || navigator.userAgent.indexOf('OPR/') >= 0; }; /// Firefox 1.0+ self.isFirefoxBrowser = function () { return typeof InstallTrigger !== 'undefined'; }; /// Safari 3.0+ self.isSafariBrowser = function () { return /constructor/i.test(window.HTMLElement) || (function (p) { return p.toString() === "[object SafariRemoteNotification]"; })(!window['safari'] || (typeof safari !== 'undefined' && window['safari'] 。推送通知)); }; /// Edge 20+ self.isEdgeBrowser = function () { return !self.isIEBrowser() && !!window.StyleMedia; }; /// Chrome 1 - 87 self.isChromeBrowser = function () { return (!!window.chrome && (!!window.chrome.webstore || !!window.chrome.runtime)) || (navigator.userAgent.indexOf("Chrome") > -1) && !self.isOperaBrowser(); }; /// 边缘(基于铬) self.isEdgeChromiumBrowser = function () { return self.isChromeBrowser() && (navigator.userAgent.indexOf("Edg") != -1); }; /// 闪烁 self.isBlinkBasedOnBrowser = function () { return (self.isChromeBrowser() || self.isOperaBrowser()) && !!window.CSS; }; /// 返回导航器的名称 self.browserName = function () { if (self.isOperaBrowser()) return "Opera";如果(self.isEdgeBrowser())返回“边缘”; if (self.isEdgeChromiumBrowser()) return "Edge (based on chromium)"; if (self.isFirefoxBrowser()) 返回“火狐”; if (self.isIEBrowser()) 返回“Internet Explorer”; if (self.isSafariBrowser()) 返回“Safari”; if (self.isChromeBrowser()) return "Chrome";返回“未知”; };回归自我; }; var bName = document.getElementById('browserName'); bName.innerText = browserHelper().browserName(); #browserName { 字体系列:Arial,Verdana;字体大小:1.2rem;颜色:#ff8000;文本对齐:居中;边框:2px 实心#ff8000;边界半径:0.5rem;填充:0.5rem;最大宽度:25%;边距:自动; }
对于 chromium 浏览器来说就是这么简单。
版本:navigator.userAgentData.brands[0].version
浏览器名称:navigator.userAgentData.brands[0].brand
这让我得到了 Firefox 的版本,
let versionNumber = parseInt(window.navigator.userAgent.match(/Firefox\/([0-
9]+)\./)[1]);
tem = ua.match(/\b(OPR|Edge)\/(\d+)/i); if (tem != null) return {name : tem[1] === 'OPR' ? 'Opera' : tem[1], version : tem[2]};
