我正在使用以下腳本http://uniondesign.ca/wp-content/uploads/2012/09/accordion-demo.html並添加箭頭圖標（如果打開了任何手風琴）n根據手風琴打開n進行了更改n關閉但我被卡住了一旦所有手風琴關閉，我的圖標就不會旋轉。

還附有屏幕截圖以獲取更多詳細信息

我認為您可以在這種情況下使用toggleClass 。 這是我為了使演示工作而進行的更改。

$(document).ready(function($) {
$('#accordion').find('.accordion-toggle').addClass('icon-rotate');
$('#accordion').find('.accordion-content.default').prev('h4').removeClass('icon-rotate');
$('#accordion').find('.accordion-toggle').click(function(e) {
    $(this).toggleClass('icon-rotate').next().slideToggle().addClass('expanded');
    $(".accordion-content").not($(this).next()).slideUp().removeClass('expanded').prev('h4').addClass('icon-rotate');
});

}）;
