js jQuery 判断跳转是手机还是电脑

<script type="text/javascript">
$(function () {
var system = {};
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) {//如果是电脑跳转到百度
window.location.href = http://www.baidu.com;
} else { //如果是手机,跳转到谷歌
window.location.href = http://www.google.com;
}
});
</script>
