demo:

// 初始化(options: 可设置需要忽略掉的特征属性, callback: 回调方法)
new Fingerprint2({excludeHasLiedBrowser: true, excludeIndexedDB: true,excludeUserAgent: true, excludeJsFonts: true, customFunction: function(){
    // 获取浏览器所在机器操作系统版本
    var u = navigator.userAgent,version = '';
    if (u.indexOf('Mac OS X') > -1) {
        //ios
        var regStr_saf = /OS [\d._]*/gi;
        var verinfo = u.match(regStr_saf);
        version = (verinfo + "").replace(/[^0-9|_.]/ig,'').replace(/_/ig,'.');
    } else if (u.indexOf('Android') > -1
        || u.indexOf('Linux') > -1) {
        //android
        version = u.substr(u.indexOf('Android') + 8, u.indexOf(";", u.indexOf("Android")) - u.indexOf('Android') - 8);
    } else if (u.indexOf('BB10') > -1) {
        //黑莓bb10系统
        version = u.substr(u.indexOf('BB10') + 5, u.indexOf(";", u.indexOf("BB10")) - u.indexOf('BB10') - 5);
    } else if (u.indexOf('IEMobile')) {
        //windows phone
        version = u.substr(u.indexOf('IEMobile') + 9, u.indexOf(";", u.indexOf("IEMobile")) - u.indexOf('IEMobile') - 9);
    }
    return version;
  }}).get(function(result, components){
    console.log(result); //a hash, representing your device fingerprint
    console.log(components); // an array of FP components
    document.getElementById('ua').innerHTML = '<p>hash:</p><p>'+ result +'</p>'
  });
