JSONP事件不起作用

下面的代碼在接收到「401 - 未授權」錯誤時拋出錯誤，不會發生.fail或.always錯誤。有沒有辦法觸發失敗並檢索來自服務器的響應錯誤[myErrorMessage]？JSONP事件不起作用

的JavaScript

$(document).ready(function() { 

    var jqXHR = $.ajax({ 
     url: "http://[myDomain]/[myPage]", 
     dataType: "jsonp", 
     jsonpCallback: "myFunction" 
    }) 
     .done(function() { alert("success"); }) 
     .fail(function() { alert("error"); }) 
     .always(function() { alert("complete"); }); 

    function myFunction(data) { 
     alert("callback"); 
    } 

});

請求結果
