JS判断客户端是安卓还是iOS

if (/(iPhone|iPad|iPod|iOS)/i.test(navigator.userAgent)) { alert(navigator.userAgent); 
    window.location.href ="iPhone.html"; } else if (/(Android)/i.test(navigator.userAgent)) { alert(navigator.userAgent); 
    window.location.href ="Android.html"; } else { window.location.href ="pc.html"; };
