How to catch location header in jQuery Ajax request?

Question

JavaScript

Good afternoon!

Tell me, please, is it possible in some way to get access to the headers, namely to Location, when making an AJAX request with JQuery?
The thing is that you need to make it so that if the request goes AJAX, you need to catch this Location and redirect the browser ( window.location ), and not perform the same AJAX, but using that method. And if it turned out that the request was made directly, through the browser, in fact, go to the same Location.

How to do it?

Answer 1

$.ajax({
    url: 'https://jsonplaceholder.typicode.com/users',
    method: 'GET',
    dataType: 'json',
    success: function (data, status, jqXHR) {
        console.log(jqXHR.getAllResponseHeaders()); 
        // или jqXHR.getResponseHeader('location') (если такой header есть) 
    }
});

// pragma: no-cache
// content-type: application/json; charset=utf-8
// cache-control: public, max-age=14400

How is it like that?

$(document).ajaxComplete(function (event, xhr) {
    var url = xhr && xhr.getResponseHeader('location');
    if (url) {
        window.location.assign(url);
    }
});
