javascript - 如何在单击时切换 Slick slider (向下滑动并向上滑动)

Question

我正在尝试在某些 Slick slider 上获得平滑的向下滑动动画。

我需要 slider 和“元素”按钮在单击上述标题时以向下滑动的方式进行动画处理。

我有它， slider /按钮容器确实在单击时向下滑动(切换一个改变容器最大高度的类)，但是 slider 和按钮只是弹出到 View 中并且不会向下动画容器。

Codepen 链接:https://codepen.io/Finches/pen/jYrzWv

在此处实现平滑的向下滑动过渡有什么帮助吗？代码片段...

.service-content-wrapper {
  margin: 0 auto;
  width: 100%;
  visibility: hidden;
  margin-bottom: 25px;
  max-height: 0;
  transition: max-height 2s;
}

.accordion-content-wrapper {
  background: blue;
}

.active {
  max-height: 1000px;
  visibility: visible;
}

$('.title-box').click(function() {
  $(this).siblings('.service-content-wrapper').toggleClass('active');
});

Answer 1

如果您想在不使用 @keyframes 的情况下通过 css 设置高度动画，您可能需要更改一些内容，看看下面是否是您想要的幻灯片显示方式，请尝试全屏查看。

$('.accordion-content-wrapper').slick({
  prevArrow: false
});

$('.title-box').click(function() {
  $(this).siblings('.service-content-wrapper').toggleClass('active');
});

body {
  font-family: 'Open Sans', sans-serif;
}

.title-box h1 {
  margin: 0 auto;
  text-align: center;
  padding: 25px;
}

.service-content-wrapper {
  margin: 0 auto;
  width: 100%;
  /*   margin-bottom: 25px; */
  height: 0px;
  position: relative;
  transition: 1s;
}

.accordion-content-wrapper {
  background: blue;
}

.active {
  transition: 1s;
  height: 350px;
}

.slide-1,
.slide-2 {
  width: 100%;
}

.slick-next {
  position: absolute;
  bottom: 10px;
  right: 10px;
}

.title-box {
  background: gray;
  width: 100%;
  z-index: 9999 !important;
  position: relative;
}

.service-container {
  /*   background: pink; */
  margin: 10px;
  overflow: hidden;
  position: relative;
}

.page-container {
  padding: 25px;
}

.btn {
  padding: 15px;
  background: salmon;
  text-align: center;
  text-transform: uppercase;
  font-weight: 900;
  margin-top: 15px;
  margin-bottom: 15px;
}

.btn:hover {
  background: red;
}
