PPK's script is THE authority for this kind of things, as @Jalpesh said, this might point you in the right way

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;
    }
