hybrid方法的可能：
    Mozilla/5.0

    AppleWebKit/604.1.38 (KHTML, like Gecko) 
    Mobile/15A372 weibo/80011134

    var os = function() {
        var ua = navigator.userAgent,
        isWindowsPhone = /(?:Windows Phone)/.test(ua),
        isSymbian = /(?:SymbianOS)/.test(ua) || isWindowsPhone, 
        isAndroid = /(?:Android)/.test(ua), 
         isFireFox = /(?:Firefox)/.test(ua), 
         isChrome = /(?:Chrome|CriOS)/.test(ua),
         isTablet = /(?:iPad|PlayBook)/.test(ua) || (isAndroid && !/(?:Mobile)/.test(ua)) || (isFireFox && /(?:Tablet)/.test(ua)),
         isPhone = /(?:iPhone)/.test(ua) && !isTablet,
         isPc = !isPhone && !isAndroid && !isSymbian;
         return {
            isTablet: isTablet,
            isPhone: isPhone,
            isAndroid : isAndroid,
            isPc : isPc
        };
     }();
     if(os.isAndroid || os.isPhone || os.isTablet){
        document.write(‘mobile‘)
     }else{
        document.write(‘pc‘);
     }

移动端返回的是：“Mozilla/5.0 (Linux; Android 6.0; Nexus 5 Build/MRA58N) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Mobile Safari/537.36”

移动端有“Mobile”这个值。。PC端没有；
