如何阻止此 CSS 手风琴自动向下滚动？

Question

我正在为我正在制作的网站使用 CSS 和 jQuery 制作的手风琴。该站点还使用 Bootstrap 为其其他部分设置样式。

每次打开或关闭标签页时，页面都会出于某种原因自动向下滚动，我应该更改什么？提前谢谢大家。

$(document).ready(function() {
  $("a.accordion__trigger").click(function() {
    $(this).parent().find(".accordion__content").toggleClass("accordion__content__hidden");
  });
});

.final__accordion {
  position: relative;
  display: block;
  border: 1px solid #e0e0e0;
  font-size: 0.8rem;
}

.final__accordion .accordion__item {
  display: block;
  margin-top: 5px;
}

.final__accordion .accordion__content {
  display: -webkit-box;
  display: -ms-flexbox;
  display: flex;
  -webkit-box-align: center;
  -ms-flex-align: center;
  align-items: center;
  background-color: rgba(255, 255, 255, 0.5);
  overflow: hidden;
  height: 0;
  -webkit-transition: height 1s ease, padding 0.3s linear;
  -o-transition: height 1s ease, padding 0.3s linear;
  transition: height 1s ease, padding 0.3s linear;
}

.final__accordion .accordion__content p {
  padding: 20px;
  margin: 0;
  text-align: left;
  max-width: initial;
}

.accordion__item .accordion__content {
  overflow: hidden;
  box-sizing: content-box;
  -moz-box-sizing: content-box;
}

.final__accordion .accordion__content__hidden:target {
  /*CHANGED TARGET ON TOGGLE CLASSNAME*/
  height: 150px;
  text-align: left;
}

.accordion__content__hidden {
  height: 0;
}

.final__accordion .accordion__trigger {
  text-decoration: none;
}

.final__accordion .accordion__title {
  position: relative;

  margin: 0;
  padding: 10px;
  font-size: 1em;
  background-color: rgb(234, 10, 42);
  color: #FFFFFF;
  border: 1px solid red;
  cursor: pointer;
}

.final__accordion .accordion__title:hover {
  background-color: red;
}

.final__accordion .accordion__title:after {
  position: absolute;
  top: calc(50% - 12px);
  right: 20px;

Answer 1

单击 <a>nchor 标记时，默认行为是跳转到由 href 值确定的位置。所以所有 <a> 都有 href="#/" 这基本上可以防止这种跳跃行为。
使用 jQuery 时，您需要使用 #id .01% 的时间和 .class 99.99% 的时间。所以所有 #id 都被删除了。
对于滑动等动画效果有.slideUp/Down/Toggle()
手风琴的行为是一次只能打开一个部分。因此，所有 .content 除了 .content 之后的 .trigger（即 $(this)）将 .slideUp()。那么点击.trigger之后的.content会.slideToggle().
.open 在 .title 上 .toggleClass() 以动画箭头。

顺便说一句，我从所有类中删除了 .accordion__ 部分以节省我的理智，如果你愿意，可以随意用 .accordion__ 把它弄乱。

$(".trigger").on('click', function(e) {
  $('.title').not($(this)).removeClass('open');
  $(this).toggleClass('open');
  $('.content').not($(this).next('.content')).slideUp();
  $(this).next('.content').slideToggle();
});

  overflow-y: scroll
