jquery - Check if all children elements are hidden

Question

I'm a bit stuck here with my script:

Its a checkbox filtering all .notme images and hiding it's list items. The problem is now I cant get a working callback function for the fadeToggle. It should behave like this :

If all children of #list-team-single-container are "displayed none" - do something.

$('#show-only-my-teams').change(function(){
    $('.notme').each(function(){
        $(this).parent().parent().fadeToggle('fast', function(){
        });
    });
}); 

Answer 1

if($('#list-team-single-container').children(':visible').length == 0) {
   // action when all are hidden
}
