[averichev]

I want show fancybox when calling ajax request

But if i open overlay before open fancybox - i have errror _"this.el is undefined"_ on line 1818
this.el.addClass('fancybox-lock');

$(document).on('click', '[data-fancy]', function (e) {
        e.preventDefault();

        // show loading and overlay
        //$.fancybox.helpers.overlay.open(); // this line causes an error
        $.fancybox.showLoading();

        // post ajax request
        $.post('/ajax/', {}, function (r) {
            // open fancybox with ajax result
            $.fancybox.open(r);
        });
    })
