jQuery - get AJAX response headers

Question

How do we get access to the response headers when we fire an ajax request using jQuery? I tried with the below code as per the suggestions given in some sites. But xhr

Answer 1

For backward compatibility with XMLHttpRequest, a jqXHR object will expose the following properties and methods: getAllResponseHeaders() and getResponseHeader(). From the $.ajax() doc : http://api.jquery.com/jQuery.ajax/

For jQuery > 1.3

success: function(res, status, xhr) { 
  alert(xhr.getResponseHeader("myHeader"));
}
