圆滑的旋转木马移动导航点 [英] Slick carousel moving nav dots

问题描述

我正在使用 http://kenwheeler.github.io/slick 轮播，我需要即使有8张以上的幻灯片，也可以将点数限制为8.

I am using http://kenwheeler.github.io/slick carousel and I need to limit dots number to 8 even if there more than 8 slides.

导航点应在左右方向具有箭头，以提示用户要显示的点更多.

Nav dots should have arrows to the left and to the right that suggest user that there are more dots to show.

有人可以提出一个解决方案/在使用圆滑的自定义导航点方面有类似的经验吗?

Can anybody suggest a solution / had similar experience in customizing nav dots with slick?

推荐答案

我想出了一个解决方案使用CSS将点数限制为三个

I came up with a solution to limit the number of dots to three using CSS

/* hiding all bullets by default */
.slick-dots li {
    display: none
}
/* only displaying the active bullets and the 2 bullets next to it */
.slick-dots li.slick-active,
.slick-dots li.slick-active + li,
.slick-dots li.slick-active + li + li {
    display: block;
}
/* displaying the last three bullets when slick-active class isn't applied to any li before them  */
.slick-dots li:nth-last-child(1),
.slick-dots li:nth-last-child(2),
.slick-dots li:nth-last-child(3) {
    display: block;
}
/* hiding the last three bullets if slick-active exist before them */
.slick-dots li.slick-active ~ li:nth-last-child(1),
.slick-dots li.slick-active ~ li:nth-last-child(2),
.slick-dots li.slick-active ~ li:nth-last-child(3) {
    display: none;
}
/* specific conditions to always display the last three bullets */
.slick-dots li.slick-active + li + li:nth-last-child(3),
.slick-dots li.slick-active + li + li:nth-last-child(2),
.slick-dots li.slick-active + li + li:nth-last-child(1),
.slick-dots li.slick-active + li:nth-last-child(3),
.slick-dots li.slick-active + li:nth-last-child(2),
.slick-dots li.slick-active + li:nth-last-child(1){
    display: block;
}

当然可以使用预处理器来完成此操作，但是它可以正常工作.

Of course this can be made pretty with preprocessors but it is working.
