javascript - jQuery Accordion 不会删除单击上一个 Accordion 时的类

Question

我正在制作一个常见问题解答部分，但在使 Accordion 正确运行方面遇到了一些麻烦。

当我逐个单击它们并在打开下一个之前关闭它们时，一切都很好。但是，如果我打开一个，使其保持打开状态，然后单击下一个，“显示”类仍保留在前一个类上。

我希望我说得清楚，你可以在我的代码中看到我在说什么:

$(".js-accordion").click(function(e) {
  e.preventDefault();

  var $this = $(this);

  if ($this.next().hasClass("show")) {
    $this.removeClass("show");
    $this.next().removeClass("show");
    $this.next().stop().slideUp(350);
  } else {
    $this.addClass("show");
    $this.parent().parent().find("div .accordion__inner").removeClass("show");
    $this.parent().parent().find("div .accordion__inner").stop().slideUp(350);
    $this.next().stop().toggleClass("show");
    $this.next().stop().slideToggle(350);
  }
});

.accordion__box {
  max-width: 600px;
  margin: 20px auto;
  box-shadow: 0px 14px 20px 5px rgba(0, 0, 0, 0.1);
}

.accordion__inner {
  overflow: hidden;
  display: none;
  padding: 10px 20px;
  position: relative;
  background-color: #fff;
  border-bottom-left-radius: 5px;
  border-bottom-right-radius: 5px;
}

.accordion__header {
  border-radius: 5px;
  font-weight: 900;
  font-size: 24px;
  font-family: "Lato", sans-serif;
  margin-bottom: 0;
  color: #fff;
  display: flex;
  justify-content: space-between;
  background-color: #004a80;
  padding: 20px 30px 20px 40px;
  cursor: pointer;
  transition: all 0.3s ease-in-out;
}

.accordion__header.show {
  background-color: #EF2A72;
  border-bottom-left-radius: 0;
  border-bottom-right-radius: 0;
}

.accordion__header.show::after {
  transition: all 0.3s ease-in-out;
  transform: rotate(180deg);
}

.accordion__header::after {
  content: "\f107";
  color: #fff;
  max-width: 30px;
  height: 30px;
  width: 100%;
  border-radius: 5px;
  display: flex;
  align-items: center;
  justify-content: center;
  font-family: "Font Awesome 5 Pro";
  font-size: 30px;
  font-weight: 500;
  transition: all 0.3s ease-in-out;
}

Answer 1

您可以使用.not()排除所有不在点击js-accordion的accordion__box内的元素。

演示代码:

$(".js-accordion").click(function(e) {
  e.preventDefault();

  var $this = $(this);
  $this.toggleClass("show")//add show to one which is clicked
  $this.closest(".accordion").find(".js-accordion").not($this).removeClass("show")//remove from other
  $this.next().slideToggle(350);//show accrodian
  $this.closest(".accordion").find(".accordion__inner").not($this.next()).stop().slideUp(350);//slideup another


});

.accordion__box {
  max-width: 600px;
  margin: 20px auto;
  box-shadow: 0px 14px 20px 5px rgba(0, 0, 0, 0.1);
}

.accordion__inner {
  overflow: hidden;
  display: none;
  padding: 10px 20px;
  position: relative;
  background-color: #fff;
  border-bottom-left-radius: 5px;
  border-bottom-right-radius: 5px;
}

.accordion__header {
  border-radius: 5px;
  font-weight: 900;
  font-size: 24px;
  font-family: "Lato", sans-serif;
  margin-bottom: 0;
  color: #fff;
  display: flex;
  justify-content: space-between;
  background-color: #004a80;
  padding: 20px 30px 20px 40px;
  cursor: pointer;
  transition: all 0.3s ease-in-out;
}

.accordion__header.show {
  background-color: #EF2A72;
  border-bottom-left-radius: 0;
  border-bottom-right-radius: 0;
}

.accordion__header.show::after {
  transition: all 0.3s ease-in-out;
  transform: rotate(180deg);
}

.accordion__header::after {
  content: "\f107";
  color: #fff;
  max-width: 30px;
  height: 30px;
  width: 100%;
  border-radius: 5px;
  display: flex;
  align-items: center;
  justify-content: center;
  font-family: "Font Awesome 5 Pro";
  font-size: 30px;
  font-weight: 500;
  transition: all 0.3s ease-in-out;
