javascript - 如何在 Accordion 中切换类 "active"

标签 javascript jquery html css

我试图让我的 Accordion 的行为如下图所示，但我不知道如何使用 jquery 代码切换“事件”类。

第一个元素(“在线现金返还”)以“事件”开始，但我想在单击另一个元素时删除其类。

该图像非常清楚地解释了我想要的预期行为。

enter image description here

我的代码:

$('.menu').on('click', function() {
  $('.content').hide();
  $(this).find('.content').show();
});


$('.menu').on('click', function(event) {
  $target = $(event.target);
  $target.addClass('active');
});

最佳答案

您可以使用单个函数来完成您需要的所有操作，不需要两个监听器。

在监听器/函数内，使用 jQuery 从 div.sectionThree-container 中选择具有类 active 的所有子级，并删除此类。
现在，由于您位于单击的 .menu 内，因此 this 上下文引用您想要的单击菜单，因此只需找到其“.content”并显示它，找到 h2 并添加“active”类，找到圆圈并向其添加“active”类。

看下面，这是你需要的吗？

$('.menu').on('click', function() {
  $(".sectionThree-container .active").removeClass("active")
  $('.sectionThree-container .content').hide();
  let clickedContent = $(this);
  clickedContent.find('.content').show();
  clickedContent.find('h2').addClass('active');
  clickedContent.find('.circle').addClass('active');
});
.sectionThree-container>ul {
  list-style: none;
}

.sectionThree-container>ul p {
  display: none;
}

.sectionThreeOptions>h2 {
  font-family: Poppins;
  font-style: normal;
  font-weight: bold;
  font-size: 22px;
  line-height: 22px;
  color: #4F4F4F;
  margin-left: 22px;
  cursor: pointer;
}

.sectionThreeOptions>h2.active {
  font-family: Poppins;
  font-style: normal;
  font-weight: bold;
  font-size: 30px;
  line-height: 22px;
  color: #222222;
  margin-left: 0;
}

.sectionThree-container .circle {
  width: 32px;
  height: 32px;
  left: 142px;
  top: 2050px;
  background: #FF6B7D;
  color: #fff;
  border-radius: 50%;
  margin: 20px 0 20px 0;
  display: flex;
  justify-content: center;
  align-items: center;
  margin-right: 30px;
}

.sectionThree-container .circle.active {
  width: 60px;
  height: 60px;
  left: 128px;
  top: 1820px;

如果您想减少代码行数，可以在单个语句中进行一些 jQuery 选择，例如 clickedContent.find("h2, .circle").addClass('active')
