jquery - jQuery : IE11 AJAX error handler not giving error information

Question

在Firefox和IE11中，JQuery从AJAX调用获取的错误信息之间存在很大的差异:

ajaxData = {id: 1234, quantity: 3};
$.ajax({
    type: 'POST',
    url: BASE_URL + 'ajax/this-page-does-not-exist.php',
    dataType: 'json',
    data: ajaxData,
    error: function(xhr, textStatus, errorThrown){
        // in Firefox:
        //  - xhr.responseText has the "Not found" HTML message returned by the server
        //  - xhr.status is 404
        //  - textStatus is 'error'
        //  - errorThrown is 'Not Found'
        // in IE11:
        //  - xhr.responseText is empty
        //  - xhr.status is 0
        //  - textStatus is 'error'
        //  - errorThrown is empty

    },
    success: function(data, textStatus, xhr){
        // ...
    }
});

这是怎么了？

这可能与我在这里询问的内容相同:

IE11 returns status 0 during Ajax POST operation from an iFrame (XMLHttpRequest: Network Error 0x2ee4)

微软表示，他们将调查该问题。
