Js判断客户端是否为PC还是手持设备

 function IsPC()        {            var userAgentInfo = navigator.userAgent;            var Agents = new Array("Android", "iPhone", "SymbianOS", "Windows Phone", "iPad", "iPod");            var flag = true;            for (var v = 0; v < Agents.length; v++) {                if (userAgentInfo.indexOf(Agents[v]) > 0) { flag = false; break; }            }            return flag;        }
