在不同浏览器的桌面版本上，一切正常，两种方法都有效。但在手机上，没有一个工作。页面已完全加载，没有错误，所有内容也在移动版本上加载。只有数据不被传输。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;
   }       
   ?>

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