javascript - Slick slider 使用数据属性对带有幻灯片的导航项进行分组

转载作者：行者123 更新时间：2023-12-04 12:55:42

我正在使用 Slick Slider JS 来构建历史时间线。每个日期范围导航项都使用 data-group 连接到多张幻灯片。属性。我需要调整我的代码以转换 timeline__nav ul当第一张幻灯片匹配 data-group 时，使用上一个和下一个按钮向左或向右属性滑入 View 。
我现有的代码在下面的代码段中。

$('.timeline__slider').slick({
  infinite: false,
  arrows: false,
  dots: false,
  autoplay: false,
  speed: 800,
  cssEase: 'linear',
  slidesToShow: 2,
  slidesToScroll: 2,
  responsive: [{
    breakpoint: 800,
    settings: {
      slidesToShow: 1,
      slidesToScroll: 1
    }
  }]
});

var timeLineItem = $('.timeline__nav li').css("width");
var left = $('.timeline__nav li').offset().left;

$('.js-previous-slide').click(function() {
  $('.timeline__slider').slick('slickPrev');
  // If the first timeline__item in data-group and it matches the
  // timeline__nav item's data-group attribute, animate left.
  $('.timeline__nav ul').animate({
    'left': '+=' + timeLineItem
  }, 150, function() {});
});

$('.js-next-slide').click(function() {
  $('.timeline__slider').slick('slickNext');
  // If the first timeline__item in data-group and it matches the
  // timeline__nav item's data-group attribute, animate right.
  $('.timeline__nav ul').animate({
    'left': '-=' + timeLineItem
  }, 150, function() {});
});

$('.timeline__slider').on('afterChange', function(event, slick, currentSlide, nextSlide) {
  if (currentSlide === 0) {
    $('.js-previous-slide').prop('disabled', true);
    $('.js-previous-slide').addClass('is-disabled');
  } else {
    $('.js-previous-slide').prop('disabled', false);
    $('.js-previous-slide').removeClass('is-disabled');
  }

  if (slick.slideCount === currentSlide + 1) {
    $('.js-next-slide').prop('disabled', true);
    $('.js-next-slide').addClass('is-disabled');
  } else {
    $('.js-next-slide').prop('disabled', false);
    $('.js-next-slide').removeClass('is-disabled');
  }

  $('.timeline__nav li.is-active').removeClass('is-active');

  $('.slick-current .timeline__item').each(function() {
    $('.timeline__nav li[data-group="' + $(this).attr('data-group') + '"').addClass('is-active');
  });
});

          <p>In 1990, a grant for $175,000 was received from the federal government to build a facility, thanks to a Board member who introduced MRWC to the concept of funding applications. The 5,000 square foot facility was built with home-grade materials,
            and no blueprints or contractors. It was well ahead of most wildlife rehabilitation centres at that time and seemed far too big to ever fill. Little did we realize what was coming.</p>

最佳答案

动态时间线滑动 slider
干得好。 很好且可扩展动态分组 和 自动禁用 导航(当没有幻灯片与日期范围相关时)。
基本上，我剥离了所有数据组属性，转而采用动态方法。在初始化时，迭代导航并应用数据组属性。然后解析日期范围并评估所有幻灯片以查看列出的日期是否适合该范围。我看到我们可以进行直接匹配(例如 1989 年到 1992 年)，但是这样你就可以拥有像幻灯片一样的子集，从 1989 年到 1990 年或 1990-1991 年，它仍然会匹配那个日期范围。
我还稍微整理了您的功能，并添加了一个禁用的导航选项，该选项没有相关的日期范围幻灯片。
如果您的幻灯片只有一个日期 (1994) 或跨越 2 个不同集合 (1990-2010) 的日期范围，则可以轻松扩展此功能。

          <p>In 1990, a grant for $175,000 was received from the federal government to build a facility, thanks to a Board member who introduced MRWC to the concept of funding applications. The 5,000 square foot facility was built with home-grade materials,
            and no blueprints or contractors. It was well ahead of most wildlife rehabilitation centres at that time and seemed far too big to ever fill. Little did we realize what was coming.</p>
