判断终端是PC还是手机

//one
var system ={win: false, mac: false, xll: false };
var p = navigator.platform;
system.win = p.indexOf("Win") == 0;
system.mac = p.indexOf("Mac") == 0;
system.x11 = (p == "X11") || (p.indexOf("Linux") == 0);
if(!(system.win||system.mac||system.xll)){window.location.href=""; }


//two
function IsPC() {
    var userAgentInfo = navigator.userAgent;
    var Agents = ["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;
}
