         var ua = navigator.userAgent.toLowerCase();
         var agents = ["android", "iphone",
             "symbianos", "windows phone",
             "ipad", "ipod"
         ];
         var flag = true;
         for (var v in agents) {
             if (ua.indexOf(agents[v]) > 0) {
                 flag = false;
                 break;
             }
         }
         return flag;
     }
