I’m trying to include slider in a html page
<!DOCTYPE html>
<html>
<head>
<title>Slider Example</title>
<style>
.slider-container {
position: absolute;
top: 50%;
right: 0;
transform: translateY(-50%);
background-color: #f0f0f0;
padding: 20px;
border: 1px solid #ccc;
border-radius: 5px;
box-shadow: 0px 0px 5px rgba(0, 0, 0, 0.1);
}
.slider {
width: 300px;
margin: 0 auto;
overflow: hidden;
position: relative;
box-shadow: 0px 0px 5px rgba(0, 0, 0, 0.1);
}
.slider img {
display: block;
width: 100%;
height: auto;
}
.slider button {
position: absolute;
top: 50%;
transform: translateY(-50%);
background-color: transparent;
border: none;
font-size: 24px;
color: #555;
padding: 0 10px;
cursor: pointer;
}
.slider button.prev {
left: 0;
}
.slider button.next {
right: 0;
}
</style>
</head>
<body>
<div class="slider-container">
<h2>Slider Example</h2>
<div class="slider">
<img src="https://via.placeholder.com/500x250?text=Slide+1" alt="Slide 1">
<img src="https://via.placeholder.com/500x250?text=Slide+2" alt="Slide 2">
<img src="https://via.placeholder.com/500x250?text=Slide+3" alt="Slide 3">

</div>
<button class="prev">❮</button>
<button class="next">❯</button>
</div>
<script>
var slideIndex = 1;
showSlides(slideIndex);
function plusSlides(n) {
showSlides(slideIndex += n);
}
function currentSlide(n) {
showSlides(slideIndex = n);
}
function showSlides(n) {
var i;
var slides = document.getElementsByClassName("slider")[0].getElementsByTagName("img");
slideIndex += n; // increment or decrement slideIndex based on value of n
if (slideIndex > slides.length) { slideIndex = 1 }
if (slideIndex < 1) { slideIndex = slides.length }
for (i = 0; i < slides.length; i++) {
slides[i].style.display = "none";
}
slides[slideIndex-1].style.display = "block";
}
// add event listeners for prev and next buttons
document.querySelector('.prev').addEventListener('click', function() {
plusSlides(-1);
});
document.querySelector('.next').addEventListener('click', function() {
plusSlides(1);
});
</script>
</body>
</html>
Only the first and last slide is displayed and the slide is not advancing correctly.
Suggestions on how to fix this will be really helpful
>Solution :
function showSlides(n) {
var i;
var slides = document.getElementsByClassName("slider")[0].getElementsByTagName("img");
slideIndex = n; // set slideIndex to the value of n
if (slideIndex > slides.length) { slideIndex = 1 }
if (slideIndex < 1) { slideIndex = slides.length }
for (i = 0; i < slides.length; i++) {
slides[i].style.display = "none";
}
slides[slideIndex-1].style.display = "block";
}
