jquery - Slick Slider 自定义 HTML 分页

Question

是否可以像 Bootstrap Carousel 允许的那样，仅使用 HTML 为 Slick Slider 创建自定义分页点。

Bootstrap 分页示例

<ol class="carousel-indicators">
    <li data-target="#carouselExampleIndicators" data-slide-to="0" class="active"></li>
    <li data-target="#carouselExampleIndicators" data-slide-to="1"></li>
    <li data-target="#carouselExampleIndicators" data-slide-to="2"></li>
</ol>

我知道您可以像这样创建自定义点；

customPaging : function(slider, i) {
    var thumb = $(slider.$slides[i]).data('thumb');
    return '<a><img src="'+thumb+'"></a>';
}

但是这种方法对我想要实现的目标不起作用。这是我希望能够用作我的分页导航的内容。

jQuery(document).ready(function($){
	$('.step').click(function(){
		var elem = $(this);
		var pointer = $('#pointer');

		if( elem.hasClass('one') ){
			pointer.css('left', '0');
		}else if( elem.hasClass('two') ){
			pointer.css('left', '20%');
		}else if( elem.hasClass('three') ){
			pointer.css('left', '40%');
		}else if( elem.hasClass('four') ){
			pointer.css('left', '60%');
		}else{
			pointer.css('left', '80%');
		}

		$('.step').removeClass('active');
		elem.addClass('active');
	});
});

.steps {
	 position: relative;
	 margin-top: 4rem;
	 padding-top: 14rem;
	 display: -webkit-flex;
	 display: -moz-flex;
	 display: -ms-flex;
	 display: -o-flex;

}
 .steps #pointer svg {

	 height: auto;
}
 .steps .step {
	 width: 20%;
	 text-align: center;
}
 .steps .step svg circle {
	 fill: blue;
	 -webkit-transition: fill 0.3s ease;
	 -o-transition: fill 0.3s ease;
	 transition: fill 0.3s ease;
}

	 -o-transition: max-height 0s, opacity 0.3s ease;
	 transition: max-height 0s, opacity 0.3s ease;
}
 .steps .step.active svg circle {
	 fill: lightblue;
}
 .steps .step.active p {
	 opacity: 1;
	 max-height: unset;
}

您可以使用纯 CSS/HTML 来做到这一点。 Slick-slider 在事件幻灯片上使用 slick-active。在 CSS 中使用指针 pseudoe element ::before 和 Sign up with ::after。

.slick-dots {
  padding-top: 100px;
}
.slick-dots .slick-active  {
  position:relative;
}
.slick-dots .slick-active::before {
  content: "";
  /* use the ppointer instead of this link */
  background: url(https://s3-us-west-2.amazonaws.com/s.cdpn.io/652/codepen.png) top center no-repeat;
  position:absolute;
  top: -70px;
  left: -25px;
  width: 50px;
  height: 50px;
  border: 1px solid red;
}

.slick-dots .slick-active::after {
  content: "Sign Up ";
  position:absolute;
  top: 30px;
  left: -50px;
  width: 100px;
  border: 1px solid red;
}

$().ready(function(){
  $('.slick-carousel').slick({
    arrows: true,
    centerPadding: "0px",
    dots: true,
    slidesToShow: 1,
    infinite: false
  });
});

body {
  background: #333;
  font-family: sans-serif;
  margin: 0;
  padding: 0;
}
body .slick-slide .slide-content {
  margin: 0 10%;
  padding: 50px 100px;
  background: #fff;
}
body .slick-list {
  margin: 20px 0px;
}
body .slick-prev,
body .slick-next {
  position: absolute;

  height: 30px;
}
body .slick-prev:before,
body .slick-next:before {
  content: ">";
  color: #fff;
  font-size: 25px;
}
body .slick-prev {
  left: 10%;
}
body .slick-prev:before {
  content: "<";
}
body .slick-dots {
  list-style: none;
  margin: 0 auto;
  text-align: center;
}
body .slick-dots li {
  display: inline-block;
}
body .slick-dots li button {
  transition: 0.2s background-color ease-in-out 0s;

  margin-right: 10px;
  border-radius: 50%;
}
body .slick-dots li.slick-active button {
  background-color: #fff;
}
.slick-dots {
  padding-top: 100px;
}
.slick-dots .slick-active {
  position: relative;
}
.slick-dots .slick-active::before {
  content: "";
  background: url(https://s3-us-west-2.amazonaws.com/s.cdpn.io/652/codepen.png)
    top center no-repeat;
  position: absolute;
  top: -70px;
  left: -25px;
  width: 50px;
  height: 50px;
  border: 1px solid red;
}
.slick-dots .slick-active::after {
  content: "Sign Up ";
  position: absolute;

将 SVG 指针用作外部文件。

使用这些。如果它们不起作用，请在私有(private)/隐身窗口中打开。并且您不应该使用 AdBlocker。

请记住，您需要调整 ::before 和 ::after 元素的位置和大小。
