クリックすると、ブートストラップのアコーディオンパネルヘッダーをどのようにターゲットできますか？

Question

私はブートストラップcollapse（アコーディオン）を使用していて、開かれている場合は.panel-headerの背景色を変更したいと考えています。これまでのところ私はこれを持っているが、私はつまみを打った。

$('.panel-group').on('show.bs.collapse', function() { 
    $(this).find('.panel-heading').addClass('active-panel'); 
}); 

$('.panel-group').on('hide.bs.collapse', function() { 
    $(this).find('.panel-heading').removeClass('active-panel'); 
}); 

問題は.panel-groupは（ドキュメントは構造のために上記のリンクを参照）、すべての.panel-heading年代の親であり、すべてのパネルで、それの結果がそれらに適用される.active-panelクラスを持つということです。クリックされたパネル見出しのみをターゲットにするにはどうすればよいですか？

月、このヘルプあなた..

$('.panel-collapse.in').siblings('.panel-heading').addClass('active'); 
 
    $('.panel-collapse').on('show.bs.collapse', function() { 
 
    $(this).siblings('.panel-heading').addClass('active'); 
 
    }); 
 

 
    $('.panel-collapse').on('hide.bs.collapse', function() { 
 
    $(this).siblings('.panel-heading').removeClass('active'); 
 
    });

.active{ 
 
    background:#FF0 !important; 
 
}
