javascript - How to determine error if using $.post() or $.get() -

-

i know how handle errors $.post or $.get 

$.post(url,data,function(data,status,xhr),datatype) $.get(url,data,function(data,status,xhr),datatype)

without using $.ajax has error handler.

$.ajax({     url: url,     type: $(this).attr("method"),     datatype: "json",     data: data,     processdata: false,     contenttype: false,     success: function (data, status)     {      },     error: function (xhr, desc, err)     {       } });

jquery's post , get promisses, can chain functions done, fail , always on these:

var jqxhr = $.post( "example.php", function() {     alert("success"); }) .done(function() {     alert("second success"); }) .fail(function() {     alert("error"); }) .always(function() {     alert("finished"); });

or later, varibale:

jqxhr.always(function() {     alert("second finished"); });

see documentation.
