Find element on site from a fancybox iframe

问题

I'm trying to update a element on my site from a fancybox. In the fancybox i do a $.post() and get back html data that i want to populate in a div on my page. I open up a iframe window with html and this script below is in that iframe. It cant find it from the fancybox so anybody got idea or solution on how to reach a element thats not inside the fancybox iframe?

$('.add-to-cart').click(function () {
    var $this = $(this).closest('form');

    $.post($this.attr('action'), { quantity: $this.find('#quantity_id').val() }, function (data) {
        parent.$.fancybox.close();
        $('#container').html(data);
    }, 'html');

    return false;
});

Try this:

$('#container', $(parent.document)).html(data);
