Js判断客户端是不是为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;
        }
