使用swiper js创建一个历史时间轴，每年有多个幻灯片

Question

我正在使用 Swiper JS，我正在努力寻找一种方法来从分页中删除重复项。我希望能够为每一年制作一张包含内容的幻灯片，但也为特定年份制作多张幻灯片 - 但只为其编写 1 个分页（使用 nav/swipe 工作）。

因此，如果幻灯片位于：

1989, 1990, 1992, 1992, 1992

那么分页显示为：

1989、1990、1992

（滑动和 left/right 箭头也适用于此并滚动浏览所有幻灯片，不遗漏任何幻灯片，但每个副本都停留在 1992 年）。

<div class="swiper-container">
    <!-- Additional required wrapper -->
    <div class="swiper-wrapper">
        <!-- Slides -->
        <div class="swiper-slide" year="1989">Content</div>
      <div class="swiper-slide" year="1990">Content</div>
      <div class="swiper-slide" year="1992">Content</div>
                  <div class="swiper-slide" year="1992">Content</div>
                  <div class="swiper-slide" year="1992">Content</div>
               <div class="swiper-slide" year="1993">Content</div>
    </div>
    <!-- If we need pagination -->
    <div class="swiper-pagination"></div>

    <!-- If we need navigation buttons -->
    <div class="swiper-button-prev"></div>
    <div class="swiper-button-next"></div>
</div>

var mySwiper = new Swiper ('.swiper-container', {
    // If we need pagination
    pagination: {
      el: '.swiper-pagination',
            clickable: true,
        renderBullet: function (index, className) {
          return '<span class="' + className + '">' + (menu[index]) + '</span>';
        },
    },

    // Navigation arrows
    navigation: {
      nextEl: '.swiper-button-next',
      prevEl: '.swiper-button-prev',
    },
  })

这是一个包含重复年份的干净示例：

到目前为止我尝试过的事情：

找到重复的年份并将它们从菜单中删除 - 现在的主要问题是跳过那张幻灯片。

删除重复的 dom 分页元素 - 滑动时这看起来会损坏，因为有一个点没有突出显示分页。

任何人都可以帮助我了解如何实现这一目标吗？

Answer 1

您可以通过实现自己的逻辑来实现这一点。这意味着您处理对上一个、下一个和年份元素的点击。

您使用的版本是旧版本，这就是我在 .timeline 元素上使用 trigger 的原因。新版本的 swiperjs 有 slideChange 事件，您可以利用它来获得相同的结果。

您可以在此处找到 fiddle：https://jsfiddle.net/3ryo71m5/。

这是一个例子：

var years = [];
let slideIndex = 0;
let currentSlide = 0;

var timelineSwiper = new Swiper('.timeline .swiper-container', {
  direction: 'vertical',
  loop: false,

  speed: 1600,
  pagination: '.swiper-pagination',
  paginationBulletRender: function(swiper, index, className) {
    let el = swiper.slides[index];
    var yearValue = el.getAttribute('year');

    if (!years.includes(yearValue)) {
      // Set data attribute to slides to link to year element
      el.setAttribute("data-parent", index);

      // Use this var for next iteration to group similar slides
      slideIndex = index;
      years.push(yearValue);
      let clsName = index == 0 ? "swiper-pagination-bullet-custom swiper-pagination-bullet-custom-active" : "swiper-pagination-bullet-custom";


      return `<span class="${clsName}" data-index='${index}'>${yearValue}</span>`;
    }
    el.setAttribute("data-parent", slideIndex);
    return "";
  },
  paginationClickable: false,

  breakpoints: {
    768: {
      direction: 'horizontal',
    }
  }
});

// Handle click on next arrow if not reached the end of slider
$(".swiper-button-next").on("click", function() {
  if (!timelineSwiper.isEnd) {
    timelineSwiper.slideTo(++currentSlide);
    $(".timeline").trigger("slideChange");
  }
});


// Handle click on prev arrow if not reached the beginning of slider
$(".swiper-button-prev").on("click", function() {
  if (!timelineSwiper.isBeginning) {
    timelineSwiper.slideTo(--currentSlide);
    $(".timeline").trigger("slideChange");
  }
});

// Handle click on years
$(".swiper-pagination span").on("click", function() {
  let el = $(this);
  let pageIndex = el.attr("data-index");
  timelineSwiper.slideTo(pageIndex);
  $(".timeline").trigger("slideChange");
  currentSlide = pageIndex;

});

// On slide change move active class to relevant element
$(".timeline").on("slideChange", function() {
  $(".swiper-pagination-bullet-custom-active").removeClass("swiper-pagination-bullet-custom-active");

  let active = timelineSwiper.activeIndex;
  let index = timelineSwiper.slides[active].getAttribute("data-parent");

  $(`.swiper-pagination span[data-index="${index}"]`).addClass("swiper-pagination-bullet-custom-active");
});
