I've just embarked on creating a simple landing-page website. One component of the page is a basic image slider with navigation controls powered by JavaScript. I managed to get everything functioning except for achieving a smooth transition between images - similar to the one demonstrated in this example. Upon analyzing related inquiries on Stackoverflow, I discovered that my issue lies in updating the 'display' element through
slides[i].style.display = "none"; slides[slideIndex-1].style.display = "block";Cheers, Jerome
var 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) {
var i;
var slides = document.getElementsByClassName("item");
var 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";
}
//automatic
var slideIndexAuto = 0;
showSlidesAuto();
function showSlidesAuto() {
var i;
var slides = document.getElementsByClassName("item");
var dots = document.getElementsByClassName("dot");
for (i = 0; i < slides.length; i++) {
slides[i].style.display = "none";
dots[i].className = dots[i].className.replace(" active", "");
}
slideIndexAuto++;
if (slideIndexAuto > slides.length) {
slideIndexAuto = 1
}
slides[slideIndexAuto - 1].style.display = "block";
dots[slideIndexAuto - 1].className += " active";
setTimeout(showSlidesAuto, 5000);
