javascript - 如何关闭 Accordion 菜单的打开部分？

Question

我正在尝试制作 Accordion ，但我不知道如何关闭打开的 Accordion 。如您所见，在您尝试关闭当前 View 之前， Accordion 可以正常工作。

我该怎么做？

注意: Accordion 只能在移动断点处看到。

$(function() {

  $('.footer-links-holder').click(function() {

    if ($('.footer-links-holder').hasClass('active')) {
      $('.footer-links-holder').removeClass('active')
    }

    $(this).toggleClass('active')

  });


});

Answer 1

在删除所有事件类之前尝试存储被点击元素的当前事件状态。

例如:

$(function() {
  $('.footer-links-holder').click(function() {
    const thisIsActive = $(this).hasClass('active');
    $('.footer-links-holder.active').removeClass('active');

    if (!thisIsActive) {
      $(this).toggleClass('active');
    }
  });
});
