jquery. All elements of class 'closer' now fire off an AJAX request to attr 'ajax_href' and remove themselves from the DOM

ajax_close_button.js

$('.closer').click(function() {
    var url = $(this).attr('ajax_href');
    $.ajax({
        type: "POST",
        url: url,
    });

    $(this).parent().fadeOut('fast', function() {
      console.log('Im gone);
    });
});
