在最后一张幻灯片后继续滚动

Question

我有一个滑块，当滑块点击最后一张幻灯片时，它将继续向下滚动页面？

请看这个代码笔：

$(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) {
e.preventDefault();
if  (e.originalEvent.deltaY < 0) {
$(this).slick('slickNext'); 
} else {
$(this).slick('slickPrev')
}
}));

Answer 1

您可以通过检查它是否是最后一个 silde 来实现这一点，然后不要阻止默认操作，这将触发页面上的滚动，其他明智的 防止默认操作并滑动滑块：

if (slideCount - totalSildeToShow == currentIndex)
return;

请参阅下面的片段：

$(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')
}
}));

Answer 2

无论如何，

这可以反向工作吗？目前，当用户向上滚动备份网站时，滑块只是停留在循环中......

我知道这是个老问题，但我找到了这样的解决方案：

if (e.originalEvent.deltaY < 0) {
if (currentIndex === 0) 
return;
e.preventDefault();
$(this).slick('slickPrev');
} else {
if (slideCount - totalSildeToShow === currentIndex)
return;
e.preventDefault();
$(this).slick('slickNext');
}
