説明補足説明コード分割コード関連書籍コメント投稿

このサンプルは、jQueryのhoverAccordion()プラグインを利用してホーバー型のアコーディオンを表示します。マウスをタブ上に移動すると自動的にコンテンツが表示されます。

      $('#accordion').hoverAccordion({   
        activateitem: '1',   
        speed: 'fast'  
      });   
      $('#accordion').children('li:first').addClass('firstitem');   
      $('#accordion').children('li:last').addClass('lastitem');   
    });
