JS判斷當前手機類型

window.onload = function () {
    var u = navigator.userAgent;
    if (u.indexOf('Android') > -1 || u.indexOf('Linux') > -1) {//安卓手機
    alert("安卓手機");
    // window.location.href = "mobile/index.html";
    } else if (u.indexOf('iPhone') > -1) {//蘋果手機
    // window.location.href = "mobile/index.html";
    alert("蘋果手機");
    } else if (u.indexOf('Windows Phone') > -1) {//winphone手機
    alert("winphone手機")
    // window.location.href = "mobile/index.html";
    }
}
