jquery - 我怎样才能让这个 Accordion 中的元素在第二次点击它们后切换和隐藏内容？

标签 jquery html css

我有一个用 css3 制作的 Accordion ，当使用 :target 伪类点击时，将内容的高度设置为零，然后设置为 150px。我想使用 jquery 使内容在我再次单击同一元素时切换，我该怎么做？

我试过创建一个单独的类并在查询中使用 toggleClass 方法。

$(document).ready(function() {
  $("a.accordion__trigger").click(function() {
    $("accordion__trigger").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: flex;
  align-items: center;
  background-color: rgba(255, 255, 255, 0.5);
  overflow: hidden;
  height: 0;
  -webkit-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;
}

.final__accordion .accordion__content:target {
  height: 150px;
  text-align: left;
}

.accordion__content__hidden {
  height: 0;
}

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

.final__accordion .accordion__title {
  position: relative;
  display: block;
  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;
  width: 15px;
  height: 15px;
  border-left: 1px solid #FFFFFF;
  border-bottom: 1px solid #FFFFFF;
  -webkit-transform: rotate(-45deg);
  transform: rotate(-45deg);
  content: "";
}

  <div class="accordion__item">

    <div id="final__tab3" class="accordion__content">

最佳答案

我建议您在单击 anchor 元素时切换内容元素上的类。而且，如果您在 CSS 中的 toggleClass 名称上添加 :target 样式，那么它将像魅力一样工作。

为了您的信息，我已将 jQuery 单击事件更改为:$(this).parent().find(".accordion__content").toggleClass("accordion__content__hidden"); 并更改了目标样式从 accordion__content:target 到 accordion__content__hidden:target CSS。

请参阅下面的代码段:

$(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: flex;
  align-items: center;
  background-color: rgba(255, 255, 255, 0.5);
  overflow: hidden;
  height: 0;
  -webkit-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;
}

.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;
  display: block;
  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;
  width: 15px;
  height: 15px;
  border-left: 1px solid #FFFFFF;
  border-bottom: 1px solid #FFFFFF;
  -webkit-transform: rotate(-45deg);
  transform: rotate(-45deg);
