How do I get HTTP error response code in Jquery POST

I have a wrapper function used to send requests to a server, I need to do something specific if the server returns a code of 401 and I'm not sure how to get this data

$.mobile.showPageLoadingMsg();
$.post(apiUrl+method,p,function(d) {

$.mobile.hidePageLoadingMsg();
console.log(d.success);
console.log(d.message);

if(d.success == true){
window[callback](d.data);
}
else{
if(d.message != null){
alert(d.message);
}
}
},'json')
.error(function() {
//need to check for 401 status here to do something
$.mobile.hidePageLoadingMsg();
alert("error");
});


If my server side code throws a 401 exception the jquery .error function picks this up just because its not 200 OK but I need to check if its a 401 code.

Answer

In the error callback, check xhr.status where xhr is the first argument to the function.
