tilda + ajax (post) 或 XMLHttpRequest mobile don't send

Question

在不同浏览器的桌面版本上，一切都很好，两种方法都能工作。但在移动设备上，没有一个是有效的。页面已完全加载，没有任何错误，所有内容也都加载在移动版上。只有数据不传输。你怎么能决定？

$(document).ready(function(){
var user  = ''; // name
var user2 = ''; // email
var x     = localStorage.getItem("memberarea_profile");
var x2    = JSON.parse(x);
var x3    = window.location; // current url
var dataString = 'email='+user2+'&name='+ user+'&page='+ x3;
$.ajax({
type: 'POST',
url: 'https://server',
crossDomain: true,
data: dataString,
success: function(responseData, textStatus, jqXHR) {
},
error: function(xhr, status, error) {
var err = eval("(" + xhr.responseText + ")");
alert(err.Message);
}
});
function getXmlHttp(){
var xmlhttp;
try {
xmlhttp = new ActiveXObject("Msxml2.XMLHTTP");
} catch (e) {
try {
xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");
} catch (E) {
xmlhttp = false;
}
}
if (!xmlhttp && typeof XMLHttpRequest!='undefined') {
xmlhttp = new XMLHttpRequest();
}
return xmlhttp;
} 
var xhr = getXmlHttp();
//var xhr = new XMLHttpRequest();
xhr.open("POST", '//server', true);
xhr.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
xhr.onreadystatechange = function() {
if(xhr.readyState == XMLHttpRequest.DONE && xhr.status == 200) {
alert('Done');
}
}
xhr.send(dataString);
});

<?php
switch ($_SERVER['HTTP_ORIGIN']) {
case 'http://server': case 'https://server':
header('Access-Control-Allow-Origin: '.$_SERVER['HTTP_ORIGIN']);
header('Access-Control-Allow-Methods: GET, PUT, POST, DELETE, OPTIONS');
header('Access-Control-Max-Age: 1000');
header('Access-Control-Allow-Headers: Content-Type, Authorization, X-Requested-With');
break;
}       
?>

第二个函数中似乎缺少new XMLHttpRequest();的情况。这是默认的类别，所以大多数移动设备都会使用
