光滑的滑块 - 在 li.slick 活动点之前添加 class
Slick slider - Add class before li.slick-active dot
我有 Slick Slider (#my-slider),我想添加 class (.past)所有 .slick-dots li 元素 before li.slick-active one.
它目前的样子
我想要它的样子
我尝试了以下方法:
(function ($) {
jQuery(document).ready(function () {
$('#my-slider').on('init', function(event, slick){
var $items = slick.$dots.find('li.slick-active').prevAll();
$items.addClass('past');
});
$('#my-slider').slick({
dots: true,
arrows: true,
infinite: false,
speed: 500,
fade: true,
autoplay: false,
cssEase: 'linear'
});
});
})(jQuery);
还有这个
(function ($) {
jQuery(document).ready(function () {
$('#my-slider').on('init', function(event, slick){
$('#my-slider .slick-dots li.slick-active').prevAll().addClass('past');
});
$('#my-slider').slick({
dots: true,
arrows: true,
infinite: false,
speed: 500,
fade: true,
autoplay: false,
cssEase: 'linear'
});
});
})(jQuery);
但运气不好。
滑块有效,但它根本不提供 过去 class。
您可以使用 beforeChange
光滑事件 add/remove .past
类 使用 nextSlide
值在所有点上。
Note: You do not need to use jQuery(document).ready(function () { });
inside (function ($) { })(jQuery);
. The first function is
shorthand for doc ready, so you are calling doc ready twice. Remove
jQuery(document).ready(function () { });
as it is not needed.
请参阅下面的现场演示,了解您在代码中的注释问题...
// our slick mySlider
let mySlider = $('#my-slider').slick({
slidesToShow: 1,
slidesToScroll: 1,
dots: true,
arrows: false,
adaptiveHeight: true,
autoplay: true,
pauseOnHover: false,
pauseOnFocus: false,
autoplaySpeed: 1000
});
// our mySlider dots
let dots = $('.slick-dots > LI', mySlider);
// before mySlider change slick event
mySlider.on('beforeChange', function(event, slick, currentSlide, nextSlide) {
// remove dot past classes on dots after next slide dot
$(dots[nextSlide]).nextAll().removeClass('past');
// add dot past classes on dots before next slide dot
$(dots[nextSlide]).prevAll().addClass('past');
});
