Bootstrap手风琴为特定面板添加活动类

Question

How add active class on opened panel ? I open panel by hash.

 $(document).ready(function () {
            var id = window.location.hash;
            $(id).trigger('click');
            $("#accordion").find('id').addClass("in");
        });
        }

But now i need add active class on .panel-header . With click i did this

 $('.panel-heading a').click(function() {
    $(this).parents('.panel-header').addClass('active');
});

How add active class without user click ? On .panel-header to opened panel?

Here code with html JsFiddle
