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/tes         


        

Answer 1

The third argument is the XMLHttpRequest object, so you can do whatever you want.

$.ajax({
  url  : 'http://example.com',
  type : 'post',
  data : 'a=b'
}).done(function(data, statusText, xhr){
  var status = xhr.status;                //200
  var head = xhr.getAllResponseHeaders(); //Detail header info
});
