我正在为自己寻找一个解决方案，因为jQuery 1.9.1及以上已经删除了$。浏览器的功能。我想出了这个小函数。 它确实需要一个全局变量(我称之为mine _browser)来检查它是哪个浏览器。我已经写了一个jsfiddle来说明如何使用它，当然，它可以通过为_browser添加一个测试来扩展到其他浏览器。Foo，其中Foo是浏览器的名称。我只做了流行的。

detectBrowser ()

_browser = {}; function 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 = match ? match[1] : ""; } break; } } _browser.opera = _browser.opr; delete _browser.opr; } detectBrowser(); console.log(_browser)

检查当前浏览器是否是Opera

if (_browser.opera) { // Opera specific code }

编辑修复了格式，修复了对IE11和Opera/Chrome的检测，从结果更改为browserResult。现在_browser键的顺序不重要了。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regexp问题。更新了jsFiddle链接。

加上我自己对赫尔曼答案的实现。我需要操作系统检测，所以它被添加。还包括一些ES6代码(因为我们有一个转译器)，你可能需要es5化。

detectClient() {
    let nav = navigator.appVersion,
        os = 'unknown',
        client = (() => {
            let agent = navigator.userAgent,
                engine = agent.match(/(opera|chrome|safari|firefox|msie|trident(?=\/))\/?\s*(\d+)/i) || [],
                build;

            if(/trident/i.test(engine[1])){
                build = /\brv[ :]+(\d+)/g.exec(agent) || [];
                return {browser:'IE', version:(build[1] || '')};
            }

            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],
              version: engine[1]
            };
        })();

    switch (true) {
        case nav.indexOf('Win') > -1:
            os = 'Windows';
        break;
        case nav.indexOf('Mac') > -1:
            os = 'MacOS';
        break;
        case nav.indexOf('X11') > -1:
            os = 'UNIX';
        break;
        case nav.indexOf('Linux') > -1:
            os = 'Linux';
        break;
    }        

    client.os = os;
    return client;
}

返回:对象{浏览器:"Chrome"，版本:"50"，操作系统:"UNIX"}

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

console.log(navigator.appVersion)

var ua = navigator.userAgent;

if (/Firefox\//.test(ua))
   var Firefox = /Firefox\/([0-9\.A-z]+)/.exec(ua)[1];

堆栈溢出-浏览器检测JavaScript? 堆栈溢出-如何检测Safari, Chrome, IE, Firefox和Opera浏览器?

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

    BrowserType = "Internet Explorer"
    BrVer = "6"
end if

    BrVer = "7"
end if

    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"
