<script type="text/javascript">
var version = navigator.appVersion;
alert(version);
</script>

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"

这个页面似乎有一个非常漂亮的代码片段，它只使用appString和appVersion属性作为最后的手段，因为它声称它们在某些浏览器中是不可靠的。 页面上的代码如下:

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 15+, the true version is after "OPR/" 
if ((verOffset=nAgt.indexOf("OPR/"))!=-1) {
 browserName = "Opera";
 fullVersion = nAgt.substring(verOffset+4);
}
// In older Opera, the true version is after "Opera" or after "Version"
else 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(''
 +'Browser name  = '+browserName+'<br>'
 +'Full version  = '+fullVersion+'<br>'
 +'Major version = '+majorVersion+'<br>'
 +'navigator.appName = '+navigator.appName+'<br>'
 +'navigator.userAgent = '+navigator.userAgent+'<br>'
)

我用它来获得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 { name: 'Explorer', version: 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]); return { name: M[0], version: parseInt(M[1]) }; } function getBrowser(){ let info = getInfoBrowser(); $("#i-name").html(info.name); $("#i-version").html(info.version); } <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <input type="button" onclick="getBrowser();" value="Get Info Browser"/> <hr/> Name: <span id="i-name"></span><br/> Version: <span id="i-version"></span>

这个磨合

铬;火狐浏览器;狩猎;Internet Explorer (>= 9);歌剧;边缘

给我。

为此，您需要检查navigator的值。appVersion或navigator.userAgent 尝试使用:

console.log(navigator.appVersion)

检测浏览器及其版本

此代码片段基于MDN的文章。他们给出了可以用来检测浏览器名称的各种关键字的简短提示。

为了检测Edge和UCBrowser这样的浏览器，我做了一些改动

getBrowser = () => { const userAgent = navigator.userAgent; let browser = "unkown"; // Detect browser name browser = (/ucbrowser/i).test(userAgent) ? 'UCBrowser' : browser; browser = (/edg/i).test(userAgent) ? 'Edge' : browser; browser = (/googlebot/i).test(userAgent) ? 'GoogleBot' : browser; browser = (/chromium/i).test(userAgent) ? 'Chromium' : browser; browser = (/firefox|fxios/i).test(userAgent) && !(/seamonkey/i).test(userAgent) ? 'Firefox' : browser; browser = (/; msie|trident/i).test(userAgent) && !(/ucbrowser/i).test(userAgent) ? 'IE' : browser; browser = (/chrome|crios/i).test(userAgent) && !(/opr|opera|chromium|edg|ucbrowser|googlebot/i).test(userAgent) ? 'Chrome' : browser;; browser = (/safari/i).test(userAgent) && !(/chromium|edg|ucbrowser|chrome|crios|opr|opera|fxios|firefox/i).test(userAgent) ? 'Safari' : browser; browser = (/opr|opera/i).test(userAgent) ? 'Opera' : browser; // detect browser version switch (browser) { case 'UCBrowser': return `${browser}/${browserVersion(userAgent,/(ucbrowser)\/([\d\.]+)/i)}`; case 'Edge': return `${browser}/${browserVersion(userAgent,/(edge|edga|edgios|edg)\/([\d\.]+)/i)}`; case 'GoogleBot': return `${browser}/${browserVersion(userAgent,/(googlebot)\/([\d\.]+)/i)}`; case 'Chromium': return `${browser}/${browserVersion(userAgent,/(chromium)\/([\d\.]+)/i)}`; case 'Firefox': return `${browser}/${browserVersion(userAgent,/(firefox|fxios)\/([\d\.]+)/i)}`; case 'Chrome': return `${browser}/${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 version is mapped using trident version // IE/8.0 = Trident/4.0, IE/9.0 = Trident/5.0 return version ? `${browser}/${parseFloat(version) + 4.0}` : `${browser}/7.0`; default: return `unknown/0.0.0.0`; } } browserVersion = (userAgent,regex) => { return userAgent.match(regex) ? userAgent.match(regex)[2] : null; } console.log(getBrowser());
