我正在创建一个在线商店,想用图片和“图像颜色更改器”来做出好的动画效果,就像其他在线商店一样。
当你将鼠标移动到图像上方时,我希望它会显示一个带有点和颜色更改选项的条形。
我已经配置了图像和箭头以在图像之间切换,以及图像下方的点,但我只想在鼠标在上方时显示这些点。
类似于 这个。
我已经有代码,但我不知道在哪里和如何编写代码才能实现这一目标。

let slideIndex = 1;
showSlides(slideIndex);
// Next/previous controls
function plusSlides(n) {
showSlides(slideIndex += n);
}
// Thumbnail image controls
function currentSlide(n) {
showSlides(slideIndex = n);
}
function showSlides(n) {
let i;
let slides = document.getElementsByClassName("mySlides");
let dots = document.getElementsByClassName("dot");
if (n > slides.length) {
slideIndex = 1
}
if (n < 1) {
slideIndex = slides.length
}
for (i = 0; i < slides.length; i++) {
slides[i].style.display = "none";
}
for (i = 0; i < dots.length; i++) {
dots[i].className = dots[i].className.replace(" active", "");
}
slides[slideIndex - 1].style.display = "block";
dots[slideIndex - 1].className += " active";
}
