以下のコードを使用してみましたが、IE6ではChromeとMozillaが機能しないという結果しか表示されません。

<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>

出力：

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

バージョン「Firefox/12.0」のみを入手する必要があります。

この目的のためのライブラリがあります: https://github.com/bestiejs/platform.js#readme

その後、このように使用できます

// 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)'

@Jalpeshが言ったように、PPKのスクリプトはこの種のことの権威です。これは正しい方法であなたを指すかもしれません

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;
    }

これを試してみてください..

// 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);
