How to do ajax when switching to https?

Question

AJAX

Colleagues, the site was transferred to https. ajax stopped working. Tried it in different ways. Maybe I'm doing something wrong in the code itself?

$.ajax({
type: 'POST',
url: ' https://myhost.ru/includes/ajax-php/add_to_cart.php ',
data: {id_product: id, session_id: session, count: count_product, region: region, params_product: params2},
success: function(data) {
var res = JSON.parse(data);
alert(res.count);
}
});

Answer 1

Colleagues, the issue has been resolved. I stepped myself. I connected jquery via the http link, but it was necessary via https: https://code.jquery.com/jquery-2.2.4.min.js
Due to the mixing of protocols on the site, jquery did not work.
Thank you all for your sympathy.
