我一直在寻找可以检测访问网站的用户使用的是火狐3还是火狐4的代码。我所找到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?

当前回答
为此,您需要检查navigator的值。appVersion或navigator.userAgent 尝试使用:
console.log(navigator.appVersion)

我用ASP代码做了一个检测浏览器,浏览器版本,OS和OS版本的脚本。 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。 所以我必须检测浏览器服务器端。
代码如下:
on error resume next
ua = lcase(Request.ServerVariables("HTTP_USER_AGENT"))
moz = instr(ua,"mozilla")
ffx = instr(ua,"firefox")
saf = instr(ua,"safari")
crm = instr(ua,"chrome")
max = instr(ua,"maxthon")
opr = instr(ua,"opera")
ie4 = instr(ua,"msie 4")
ie5 = instr(ua,"msie 5")
ie6 = instr(ua,"msie 6")
ie7 = instr(ua,"msie 7")
ie8 = instr(ua,"trident/4.0")
ie9 = instr(ua,"trident/5.0")
if moz>0 then
BrowserType = "Mozilla"
BrVer = mid(ua,moz+8,(instr(moz,ua," ")-(moz+8)))
end if
if ffx>0 then
BrowserType = "FireFox"
BrVer = mid(ua,ffx+8)
end if
if saf>0 then
BrowserType = "Safari"
BrVerPlass = instr(ua,"version")
BrVer = mid(ua,BrVerPlass+8,(instr(BrVerPlass,ua," ")-(BrVerPlass+8)))
end if
if crm>0 then
BrowserType = "Chrome"
BrVer = mid(ua,crm+7,(instr(crm,ua," ")-(crm+7)))
end if
if max>0 then
BrowserType = "Maxthon"
BrVer = mid(ua,max+8,(instr(max,ua," ")-(max+8)))
end if
if opr>0 then
BrowserType = "Opera"
BrVerPlass = instr(ua,"presto")
BrVer = mid(ua,BrVerPlass+7,(instr(BrVerPlass,ua," ")-(BrVerPlass+7)))
end if
if ie4>0 then
BrowserType = "Internet Explorer"
BrVer = "4"
end if
if ie5>0 then
BrowserType = "Internet Explorer"
BrVer = "5"
end if
if ie6>0 then
BrowserType = "Internet Explorer"
BrVer = "6"
end if
if ie7>0 then
BrowserType = "Internet Explorer"
BrVer = "7"
end if
if ie8>0 then
BrowserType = "Internet Explorer"
BrVer = "8"
if ie7>0 then BrVer = BrVer & " (in IE7 compability mode)"
end if
if ie9>0 then
BrowserType = "Internet Explorer"
BrVer = "9"
if ie7>0 then BrVer = BrVer & " (in IE7 compability mode)"
if ie8>0 then BrVer = BrVer & " (in IE8 compability mode)"
end if
OSSel = mid(ua,instr(ua,"(")+1,(instr(ua,";")-instr(ua,"("))-1)
OSver = mid(ua,instr(ua,";")+1,(instr(ua,")")-instr(ua,";"))-1)
if BrowserType = "Internet Explorer" then
OSStart = instr(ua,";")
OSStart = instr(OSStart+1,ua,";")
OSStopp = instr(OSStart+1,ua,";")
OSsel = mid(ua,OSStart+2,(OSStopp-OSStart)-2)
end if
Select case OSsel
case "windows nt 6.1"
OS = "Windows"
OSver = "7"
case "windows nt 6.0"
OS = "Windows"
OSver = "Vista"
case "windows nt 5.2"
OS = "Windows"
OSver = "Srv 2003 / XP x64"
case "windows nt 5.1"
OS = "Windows"
OSver = "XP"
case else
OS = OSSel
End select
Response.write "<br>" & ua & "<br>" & BrowserType & "<br>" & BrVer & "<br>" & OS & "<br>" & OSver & "<br>"

var ua = navigator.userAgent;
if (/Firefox\//.test(ua))
var Firefox = /Firefox\/([0-9\.A-z]+)/.exec(ua)[1];
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());
这是对Kennebec答案的改进。
mbrowser=function(){
this.spec_string= navigator.userAgent;
this.name= this.get_name();
this.version= this.get_version();
};
mbrowser.prototype.get_name=function(){
var spec_string=this.spec_string;
var matches=spec_string.match(/(opera|chrome|safari|firefox|msie|trident(?=\/))\/?\s*(\d+)/i) || [];
// Work with the matches.
matches=matches[2]? [matches[1], matches[2]]: [navigator.appName, navigator.appVersion, '-?'];
// Trident.
if(/trident/i.test(matches[1])){
var temp=/\brv[ :]+(\d+)/g.exec(spec_string) || [];
return 'IE';
}
// Chrome.
if(matches[1]==='Chrome'){
var temp=spec_string.match(/\bOPR|Edge\/(\d+)/)
if(temp!=null) {return 'Opera';}
}
if((temp=spec_string.match(/version\/(\d+)/i))!=null){
matches.splice(1,1,temp[1]);
}
var name=matches[0];
return name;
};
mbrowser.prototype.get_version=function(){
var spec_string=this.spec_string;
var matches=spec_string.match(/(opera|chrome|safari|firefox|msie|trident(?=\/))\/?\s*(\d+)/i) || [];
// Work with the matches.
matches=matches[2]? [matches[1], matches[2]]: [navigator.appName, navigator.appVersion, '-?'];
// Trident.
if(/trident/i.test(matches[1])){
var temp=/\brv[ :]+(\d+)/g.exec(spec_string) || [];
var version=(temp[1]||'');
return version;
}
// Chrome.
if(matches[1]==='Chrome'){
var temp=spec_string.match(/\bOPR|Edge\/(\d+)/)
var version=temp[1];
if(temp!=null) {return version;}
}
if((temp=spec_string.match(/version\/(\d+)/i))!=null){
matches.splice(1,1,temp[1]);
}
var version=matches[1];
return version;
};
// m=module.
var browser=new mbrowser();
console.log(browser.name); // Chrome
console.log(browser.version); // 109
这段代码从spec_string (navigator.userAgent)中推导出浏览器名称和编号。但是有各种各样的spec_string,它们有各自的浏览器名称和编号。我没有条件去检查,但是其中的一小部分。如果你能发布一个你知道的浏览器名称和编号的spec_string,那就太好了。然后我可以相应地更新代码。
然后,我将按照以下方式慢慢地构建spec_string项的列表。
'spec_string1'=>[name,number],
'spec_string2'=>[name,number],
以后,无论何时对代码进行更改,都可以在所有已知的spec_string转换上自动对其进行测试。
我们可以一起做这件事。
您可以看到浏览器显示的内容,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); // outputs: `Chrome 62`
