JS判断当前手机类型

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