我可以为光滑的滑块的每个自定义点使用不同的图像吗？

问题描述

我对滑滑的资深人士有疑问：

我想在圆滑的滑块上放置点的自定义图像，但是我想使用其他图像我的滑点。例如，我有5张幻灯片，我希望我的5个点有单独的图像，所以有5张不同的图像（如果我在活动状态和非活动状态使用不同的图像，则为10张）

有人可以对此提出建议吗？我想在这里尝试一下，但是后来我意识到，每个点仅适用于相同的图像：

 $('.productslider').slick({
                lazyLoad: 'ondemand',dots: true,customPaging : function(slider,i) {
                    return '<a href="#"><img src="images/realmix/products/freshness_energy_active.png" /><img src="images/realmix/products/freshness_energy_active.png" /></a>';
                },speed: 300,slidesToShow: 1,slidesToScroll: 1,adaptiveHeight: true,infinite: true,responsive: [
                    {
                        breakpoint: 400,settings: {
                            mobileFirst: true,centerMode: true,centerPadding: '10px',dots: true

                        }
                    }
                ]
              });

解决方法

您可以为幻灯片div分配一个自定义图像url作为数据属性，然后在光滑的init上循环遍历各个点，获取自定义点图像url并通过幻灯片id将其渲染为光滑的点。

在我的示例中，请注意，我正在使用此data属性在.slick-slide div中设置点图像...

data-dot-img="https://i.imgur.com/6X5GKWJ.png"

请参见下面的工作示例...

// 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);
