How do I get the HTTP status code with jQuery?

Question

I want to check if a page returns the status code 401. Is this possible?

Here is my try, but it only returns 0.

$.ajax({     url: "http://my-ip/test/test.php",     data: {},     complete: function(xhr, statusText){     alert(xhr.status);      } }); 

Answer 1

this is possible with jQuery $.ajax() method

$.ajax(serverUrl, {    type: OutageViewModel.Id() == 0 ? "POST" : "PUT",    data: dataToSave,    statusCode: {       200: function (response) {          alert('1');          AfterSavedAll();       },       201: function (response) {          alert('1');          AfterSavedAll();       },       400: function (response) {          alert('1');          bootbox.alert('<span style="color:Red;">Error While Saving Outage Entry Please Check</span>', function () { });       },       404: function (response) {          alert('1');          bootbox.alert('<span style="color:Red;">Error While Saving Outage Entry Please Check</span>', function () { });       }    }, success: function () {       alert('1');    }, });
