Question

我有一个滑块，当滑块碰到最后一张幻灯片时，它会继续向下滚动页面吗？

请参阅此Codepen：

int **p;

Answer 1

您可以通过检查是否为最后一个对象来实现此目的，然后不要阻止默认操作，这将触发在页面上滚动，否则请使用preventDefault操作并滑动滑块：

 if (slideCount - totalSildeToShow == currentIndex)
      return;

请参见以下代码段：

$(document).ready(function() {
  $('.customer-logos').slick({
    slidesToShow: 4,
    slidesToScroll: 1,
    autoplay: false,
    autoplaySpeed: 1500,
    arrows: false,
    dots: false,
    pauseOnHover: false,
    responsive: [{
      breakpoint: 768,
      settings: {
        slidesToShow: 4
      }
    }, {
      breakpoint: 520,
      settings: {
        slidesToShow: 3
      }
    }]
  });
});

const slider = $(".customer-logos");


slider.on('wheel', (function(e) {

  var slideCount = $(this)[0].slick["slideCount"];
  var currentIndex = $(this).slick("slickCurrentSlide");
  var totalSildeToShow =  $(this)[0].slick.options["slidesToShow"];

  if (e.originalEvent.deltaY < 0) {

    e.preventDefault();
    $(this).slick('slickPrev');

  } else {
    if (slideCount - totalSildeToShow == currentIndex)
      return;
    e.preventDefault();
    $(this).slick('slickNext')
  }
}));
