如何使用JavaScript检测我的浏览器版本和操作系统？

标签： javascript browser operating-system version

我尝试使用下面的代码，但它只显示Chrome和Mozilla中的结果不能在IE6中运行。 

<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>

输出：

Browser CodeName: Mozilla

Browser Name: Netscape

Browser Version: 5.0 (Windows)

Cookies Enabled: true

Platform: Win32

User-agent header: Mozilla/5.0 (Windows NT 5.1; rv:12.0) Gecko/20100101 Firefox/12.0

我只需要获得“Firefox / 12.0”版本。

I＆＃39; M伤感地说：我们的sh *吨的运气在这一个

。

我想推荐给WhichBrowser的作者：每个人都撒谎。

基本上，没有浏览器是诚实的。无论你使用Chrome还是IE，他们都会告诉你他们是＆＃34; Mozilla Netscape＆＃34;有Gecko和Safari支持。在这个帖子中飞来飞去的任何小提琴上自己试试吧：

hims056's fiddle

Hariharan's fiddle

或任何其他...尝试使用Chrome（可能仍会成功），然后尝试使用最新版本的IE，你会哭。当然，有一些启发式方法可以做到这一点，但是掌握所有边缘情况将会很乏味，并且它们很可能在一年的时间内不再起作用。

拿你的代码，例如：

<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说：

  

浏览器代码名称：Mozilla

     

浏览器名称：Netscape

     

浏览器版本：5.0（Windows NT 6.1; WOW64）AppleWebKit / 537.36   （KHTML，像Gecko一样）Chrome / 40.0.2214.115 Safari / 537.36

     

启用Cookie：true

     

平台：Win32

     

用户代理标头：Mozilla / 5.0（Windows NT 6.1; WOW64）   AppleWebKit / 537.36（KHTML，与Gecko一样）Chrome / 40.0.2214.115   Safari浏览器/ 537.36

IE说：

  

浏览器代码名称：Mozilla

     

浏览器名称：Netscape

     

浏览器版本：5.0（Windows NT 6.1; WOW64; Trident / 7.0; SLCC2; .NET   CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729; Media Center PC   6.0; .NET4.0C; .NET4.0E; InfoPath.3; rv：11.0）像Gecko

     

启用Cookie：true

     

平台：Win32

     

用户代理标头：Mozilla / 5.0（Windows NT 6.1; WOW64; Trident / 7.0;   SLCC2; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729;   Media Center PC 6.0; .NET4.0C; .NET4.0E; InfoPath.3; rv：11.0）喜欢   壁虎

至少Chrome仍然包含一个包含＆＃34; Chrome＆＃34;确切的版本号。但是，对于IE，你必须从它支持的东西中推断出来实际弄明白（还有谁会夸耀他们支持.NET或Media Center：P），然后将它与{{1}匹配在最后得到版本号。当然，即使是这种复杂的启发式方法，一旦IE 12（或任何他们想要称之为它）出现，它们很可能会失败。

PPK的剧本是这种事情的权威，正如@Jalpesh所说，这可能会以正确的方式指出你

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;

要使用JavaScript检测操作系统，最好使用 navigator.userAgent而不是navigator.appVersion 

<script type="text/javascript">
function showMe (it, box) {
var vis = (box.checked) ? "block" : "none";
document.getElementById(it).style.display = vis;}
</script>

适用于Firefox，Chrome，Opera，Internet Explorer和Safari 

var ua="Mozilla/1.22 (compatible; MSIE 10.0; Windows 3.1)";
//ua = navigator.userAgent;
var b;
var browser;
if(ua.indexOf("Opera")!=-1) {

    b=browser="Opera";
}
if(ua.indexOf("Firefox")!=-1 && ua.indexOf("Opera")==-1) {
    b=browser="Firefox";
    // Opera may also contains Firefox
}
if(ua.indexOf("Chrome")!=-1) {
    b=browser="Chrome";
}
if(ua.indexOf("Safari")!=-1 && ua.indexOf("Chrome")==-1) {
    b=browser="Safari";
    // Chrome always contains Safari
}

if(ua.indexOf("MSIE")!=-1 && (ua.indexOf("Opera")==-1 && ua.indexOf("Trident")==-1)) {
    b="MSIE";
    browser="Internet Explorer";
    //user agent with MSIE and Opera or MSIE and Trident may exist.
}

if(ua.indexOf("Trident")!=-1) {
    b="Trident";
    browser="Internet Explorer";
}

// now for version

我无法使用相同的代码在Chrome，Firefox，IE11和Edge上获得其他一些答案。 我想出了以下内容，它似乎适用于上面列出的那些浏览器。我还想查看用户使用的操作系统。我尚未针对具有覆盖用户的用户代理设置的浏览器进行过测试，因此里程可能会有所不同。 IF的顺序对于正常工作很重要。

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
