您可以將自定義圖像 url 作為數據屬性分配給幻燈片 div，然后在 slick init 上循環遍歷您的點，獲取自定義點圖像 url 并通過幻燈片 id 將其渲染到 slick dot 中。
請注意，在我的示例中，我.slick-slide使用此數據屬性在 div 中設置了一個點圖像...
data-dot-img="https://i.imgur.com/6X5GKWJ.png"
這是一個小提琴...... https://jsfiddle.net/joshmoto/fxy7gudv/
請參閱下面的工作示例...
// my slick slider options
const options = {
slidesToShow: 1,
slidesToScroll: 1,
dots: true,
arrows: false,
adaptiveHeight: true,
autoplay: true
};
// my slick slider as const object
const mySlider = $('.slider').on('init', function(slick) {
// set this slider as const for use in set time out
const slider = this;
// slight delay so init completes render
setTimeout(function() {
// dot buttons
let dots = $('.slick-dots > LI > BUTTON', slider);
// each dot button function
$.each(dots, function(i,e) {
// slide id
let slide_id = $(this).attr('aria-controls');
// custom dot image
let dot_img = $('#'+slide_id).data('dot-img');
$(this).html('<img src="' + dot_img + '" alt="" />');
});
}, 100);
}).slick(options);
