如何检测浏览器的版本?

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

为什么不另一个解决方案:

navigator.userAgent.includes("Firefox")? log("Mozilla") :log("Chrome")

浏览器JavaScript库提供了此功能。

if (bowser.msie && bowser.version <= 6) {
  alert('Hello China');
}

它似乎保养得很好。

我用它来获得实际浏览器版本的名称和编号(int):

这个磨合

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

给我。

以下是截至2019年5月处理浏览器检测的几个著名库。

Bowser by lancedikson - 3,761★s -最后更新于2019年5月26日- 4.8KB

var result = bowser.getParser(window.navigator.userAgent); console.log(结果); 文档。write("You are using " + result.parsedResult.browser.name + " v" + result.parsedResult.browser.version + “on”+ result.parsedResult.os.name); < script src = " https://unpkg.com/bowser@2.4.0 es5.js " > < /脚本>

*支持边缘基于铬

jQuery浏览器由gabceb - 504★s -最后更新2015年11月23日- 1.3KB

明显的提到:

该浏览器- 1355★s -最后更新于2018年10月2日 Modernizr - 23,397★s -最后更新2019年1月12日-喂喂喂马，特征检测应该驱动任何canIuse风格的问题。浏览器检测实际上只是为各个浏览器提供定制的图像、下载文件或说明。

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>"

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`
