如何使用 JavaScript 检测浏览器版本和操作系统？

小开

PPK 的剧本是这类事情的权威，正如@Jalpesh 所说，这可能会给你指出正确的方向

var wn = window.navigator,
platform = wn.platform.toString().toLowerCase(),
userAgent = wn.userAgent.toLowerCase(),
storedName;


// ie
if (userAgent.indexOf('msie',0) !== -1) {
browserName = 'ie';
os = 'win';
storedName = userAgent.match(/msie[ ]\d{1}/).toString();
version = storedName.replace(/msie[ ]/,'');


browserOsVersion = browserName + version;
}

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 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);

试试这个。

// Browser with version  Detection
navigator.sayswho= (function(){
var N= navigator.appName, ua= navigator.userAgent, tem;
var M= ua.match(/(opera|chrome|safari|firefox|msie)\/?\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;
})();


var browser_version          = navigator.sayswho;
alert("Welcome to " + browser_version);

我对 Platform.js(演示在这里)有一些很好的经验，但仍然建议要谨慎:

原文

我想向您推荐《哪个浏览器: 每个人都会撒谎》的作者。

基本上，没有哪个浏览器是诚实的。无论你是使用 Chrome 还是 IE 浏览器，它们都会告诉你它们是支持 Gecko 和 Safari 的“ Mozilla Netscape”。你可以自己试试这个帖子里的任何一个小提琴:

他的小提琴

哈里哈兰的小提琴

或者其他任何东西... ... 用 Chrome 试试(可能还会成功) ，然后用最新版本的 IE 试试，你会哭的。当然，有一些启发式的方法，可以把它们都做好，但是要掌握所有的边缘情况是很乏味的，而且它们很可能在一年的时间内就不再起作用了。

以你的代码为例:

<div id="example"></div>
<script type="text/javascript">
txt = "<p>Browser CodeName: " + navigator.appCodeName + "</p>";
txt+= "<p>Browser Name: " + navigator.appName + "</p>";
txt+= "<p>Browser Version: " + navigator.appVersion + "</p>";
txt+= "<p>Cookies Enabled: " + navigator.cookieEnabled + "</p>";
txt+= "<p>Platform: " + navigator.platform + "</p>";
txt+= "<p>User-agent header: " + navigator.userAgent + "</p>";
document.getElementById("example").innerHTML=txt;
</script>

Chrome 表示:

浏览器代码: Mozilla

浏览器名称: Netscape

浏览器版本: 5.0(Windows NT 6.1; WOW64) AppleWebKit/537.36 Chrome/40.0.2214.115 Safari/537.36

启用 Cookies: true

平台: Win32

User-agent header: Mozilla/5.0(Windows NT 6.1; WOW64) AppleWebKit/537.36(KHTML，like Gecko) Chrome/40.0.2214.115 Safari/537.36

IE 表示:

浏览器代码: Mozilla

浏览器名称: Netscape

浏览器版本: 5.0(Windows NT 6.1; WOW64; Trident/7.0; SLCC2; . NET . NET CLR 3.5.30729; . NET CLR 3.0.30729; Media Center PC 6.0; . NET4.0 C; . NET4.0 E; InfoPath.3; rv: 11.0)类似于 Gecko

启用 Cookies: true

平台: Win32

用户代理头: Mozilla/5.0(Windows NT 6.1; WOW64; Trident/7.0; . NET CLR 2.0.50727; . NET CLR 3.5.30729; . NET CLR 3.0.30729; Media Center PC 6.0; . NET4.0 C; . NET4.0 E; InfoPath.3; rv: 11.0) like 壁虎

至少 Chrome 还有一个包含“ Chrome”和确切版本号的字符串。但是，对于 IE，你必须从它所支持的东西中推断出实际的版本号(还有谁会吹嘘他们支持 .NET或者 Media Center: P) ，然后将它与最后的 rv:进行匹配来得到版本号。当然，即使是这种复杂的启发式方法也很可能在 IE12(或者他们想叫它什么)出来时就失败了。

有一个用于此目的的库: https://github.com/bestiejs/platform.js#readme

那么你可以这样使用它

// example 1
platform.os; // 'Windows Server 2008 R2 / 7 x64'


// example 2 on an iPad
platform.os; // 'iOS 5.0'


// you can also access on the browser and some other properties
platform.name; // 'Safari'
platform.version; // '5.1'
platform.product; // 'iPad'
platform.manufacturer; // 'Apple'
platform.layout; // 'WebKit'


// or use the description to put all together
platform.description; // 'Safari 5.1 on Apple iPad (iOS 5.0)'

要使用 JavaScript 检测操作系统，最好使用 UserAgent 代替了 Navator.appVersion

{
var OSName = "Unknown OS";
if (navigator.userAgent.indexOf("Win") != -1) OSName = "Windows";
if (navigator.userAgent.indexOf("Mac") != -1) OSName = "Macintosh";
if (navigator.userAgent.indexOf("Linux") != -1) OSName = "Linux";
if (navigator.userAgent.indexOf("Android") != -1) OSName = "Android";
if (navigator.userAgent.indexOf("like Mac") != -1) OSName = "iOS";
console.log('Your OS: ' + OSName);
}

我无法用同样的代码在 Chrome、 Firefox、 IE11和 Edge 上找到其他一些答案。我想出了下面的方法，它似乎适用于上面列出的那些浏览器。我还想看看用户使用的是什么操作系统。我还没有使用用户覆盖的 User-Agent 设置在浏览器上测试过这一点，所以里程可能会有所不同。IF 的顺序对于正确工作非常重要。

let os, osStore, bStore, appVersion, browser;
// Chrome
if(navigator.vendor === "Google Inc."){
appVersion = navigator.appVersion.split(" ");
os = [appVersion[1],appVersion[2],appVersion[3],appVersion[4],appVersion[5]].join(" ");
os = os.split("(")[1].split(")")[0]
browser = appVersion[appVersion.length-2].split("/").join(" ");
console.log("Browser:",browser,"- OS:",os);
}


// Safari
else if(navigator.vendor === "Apple Computer, Inc."){
appVersion = navigator.appVersion.split(" ");
os = [appVersion[1],appVersion[2],appVersion[3],appVersion[4],appVersion[5]].join(" ");
os = os.split("(")[1].split(")")[0];
browser = appVersion[appVersion.length-1].split("/").join(" ");
console.log("Browser:",browser,"- OS:",os);
}


// Firefox is seems the only browser with oscpu
else if(navigator.oscpu){
bStore = navigator.userAgent.split("; ").join("-").split(" ");
browser = bStore[bStore.length-1].replace("/"," ");
osStore = [bStore[1],bStore[2],bStore[3]].join(" ");
osStore = osStore.split("-");
osStore.pop(osStore.lastIndexOf)
osStore = osStore.join(" ").split("(");
os = osStore[1];
console.log("Browser:",browser,"- OS:",os);
}


// IE is seems the only browser with cpuClass
// MSIE 11:10 Mode
else if(navigator.appName === "Microsoft Internet Explorer"){
bStore = navigator.appVersion.split("; ");
browser = bStore[1]+" / "+bStore[4].replace("/"," ");
os = [bStore[2],bStore[3]].join(" ");
console.log("Browser:",browser,"- OS:",os);
}


// MSIE 11
else if(navigator.cpuClass){
bStore = navigator.appVersion.split("; ");
osStore = [bStore[0],bStore[1]].join(" ");
os = osStore.split("(")[1];
browser = "MSIE 11 "+bStore[2].split("/").join(" ");
console.log("Browser:",browser,"- OS:",os);

// Edge
else if(navigator.appVersion){
browser = navigator.appVersion.split(" ");
browser = browser[browser.length -1].split("/").join(" ");

要获得基于 Mozilla 核心的新 Microsoft Edge，请添加:

else if ((verOffset=nAgt.indexOf("Edg"))!=-1) {
browserName = "Microsoft Edge";
fullVersion = nAgt.substring(verOffset+5);
}

之前

// In Chrome, the true version is after "Chrome"
else if ((verOffset=nAgt.indexOf("Chrome"))!=-1) {
browserName = "Chrome";
fullVersion = nAgt.substring(verOffset+7);

为此目的有3个库。你可以在线比较它们 https://www.whatsmyua.info(在不同的浏览器和设备中加载这个页面)并选择最适合你需要的。

用于 platform.js 的例子

<script src="platform.js"></script>

// on an iPad
platform.name; // 'Safari'
platform.version; // '5.1'
platform.product; // 'iPad'
platform.manufacturer; // 'Apple'
platform.layout; // 'WebKit'
platform.os; // 'iOS 5.0'
platform.description; // 'Safari 5.1 on Apple iPad (iOS 5.0)'


// or parsing a given UA string
var info = platform.parse('Mozilla/5.0 (Macintosh; Intel Mac OS X 10.7.2; en; rv:2.0) Gecko/20100101 Firefox/4.0 Opera 11.52');
info.name; // 'Opera'
info.version; // '11.52'
info.layout; // 'Presto'
info.os; // 'Mac OS X 10.7.2'
info.description; // 'Opera 11.52 (identifying as Firefox 4.0) on Mac OS X 10.7.2'

Ua-parser.js 的用法示例

<script src="ua-parser.min.js"></script>

var parser = new UAParser();
console.log(parser.getResult());
/*
/// This will print an object structured like this:
{
ua: "",
browser: {

version: "",
major: "" //@deprecated
},
engine: {

version: ""
},
os: {
name: "",
version: ""
},
device: {
model: "",
type: "",
vendor: ""
},
cpu: {
architecture: ""
}
}
*/
// Default result depends on current window.navigator.userAgent value


// Now let's try a custom user-agent string as an example
var uastring1 = "Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/535.2 (KHTML, like Gecko) Ubuntu/11.10 Chromium/15.0.874.106 Chrome/15.0.874.106 Safari/535.2";
parser.setUA(uastring1);
var result = parser.getResult();
// You can also use UAParser constructor directly without having to create an instance:
// var result = UAParser(uastring1);


console.log(result.browser);        // {name: "Chromium", version: "15.0.874.106"}
console.log(result.device);         // {model: undefined, type: undefined, vendor: undefined}
console.log(result.os);             // {name: "Ubuntu", version: "11.10"}
console.log(result.os.version);     // "11.10"
console.log(result.engine.name);    // "WebKit"
console.log(result.cpu.architecture);   // "amd64"
