Sorry for my english! :)

I submit bug. Below function, which works fine for example in jQuery v1.7.1, but i was tested it on 1.11.0 and 1.10.2 jquery and have bug.

Description a bug:

The same function is working ok. Writes and erases checked = "checked" every time, but visually bird appears for the first time, deletes the first time, but any time longer. Visually, the bird does not show up more than once.

function:

$('input[name="checkall"]').click(function() {

$( this ).is( ':checked' ) ?

$(".mlistan :checkbox").attr('checked', 'checked') :

$(".mlistan :checkbox").removeAttr('checked');

});

I hope that helped.
