Hi there,
Sorry but my JS-Knowledge is very bad. I tried to implement multiple slideshows wthin one website. I used this tutorial. But I'm not able to create more than two slideshows without bugs. I tried to adjust the JS code but wasn't successful. At least I have to implement 4 slideshows.
My Code:
<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=device-width, initial-scale=1">
<style>
* {box-sizing: border-box}
body {font-family: Verdana, sans-serif; margin:0}
.mySlides1, .mySlides2 {display: none}
img {vertical-align: middle;}
/* Slideshow container */
.slideshow-container {
max-width: 1000px;
position: relative;
margin: auto;
}
/* Next & previous buttons */
.prev, .next {
cursor: pointer;
position: absolute;
top: 50%;
width: auto;
padding: 16px;
margin-top: -22px;
color: white;
font-weight: bold;
font-size: 18px;
transition: 0.6s ease;
border-radius: 0 3px 3px 0;
user-select: none;
}
/* Position the "next button" to the right */
.next {
right: 0;
border-radius: 3px 0 0 3px;
}
/* On hover, add a grey background color */
.prev:hover, .next:hover {
background-color: #f1f1f1;
color: black;
}
</style>
</head>
<body>
<h2 style="text-align:center">Multiple Slideshows</h2>
<div class="slideshow-container">
<div class="mySlides1">
<img src="images/gallery/fulls/06.jpg" style="width:100%">

<div class="mySlides1">

</div>
<div class="mySlides1">
<img src="images/gallery/fulls/03.jpg" style="width:100%">
</div>
<a class="prev" onclick="plusSlides(-1, 0)">❮</a>
<a class="next" onclick="plusSlides(1, 0)">❯</a>
</div>
<div class="slideshow-container">
<div class="mySlides2">
<img src="images/gallery/fulls/03.jpg" style="width:100%">
</div>
<div class="mySlides2">

<div class="mySlides2">
<img src="images/gallery/fulls/01.jpg" style="width:100%">
</div>
<a class="prev" onclick="plusSlides(-1, 1)">❮</a>
<a class="next" onclick="plusSlides(1, 1)">❯</a>
</div>
<div class="slideshow-container">
<div class="mySlides3">
<img src="images/gallery/fulls/07.jpg" style="width:100%">
</div>
<div class="mySlides2">
<img src="images/gallery/fulls/03.jpg" style="width:100%">
</div>
<div class="mySlides2">
<img src="images/gallery/fulls/05.jpg" style="width:100%">
</div>
<a class="prev" onclick="plusSlides(-1, 2)">❮</a>
<a class="next" onclick="plusSlides(1, 2)">❯</a>
</div>
<script>
var slideIndex = [1,1,1];
var slideId = ["mySlides1", "mySlides2", "mySlides3"]
showSlides(1, 0);
showSlides(1, 1);
showSlides(1, 2);
function plusSlides(n, no) {
showSlides(slideIndex[no] += n, no);
}
function showSlides(n, no) {
var i;
var x = document.getElementsByClassName(slideId[no]);
if (n > x.length) {slideIndex[no] = 1}
if (n < 1) {slideIndex[no] = x.length}
for (i = 0; i < x.length; i++) {
x[i].style.display = "none";
}
x[slideIndex[no]-1].style.display = "block";
}
</script>
</body>
</html>
Standard code from https://www.w3schools.com/howto/howto_js_slideshow.asp (only JS):
var slideIndex = [1,1];
/* Class the members of each slideshow group with different CSS classes */
var slideId = ["mySlides1", "mySlides2"]
showSlides(1, 0);
showSlides(1, 1);
function plusSlides(n, no) {
showSlides(slideIndex[no] += n, no);
}
function showSlides(n, no) {
var i;
var x = document.getElementsByClassName(slideId[no]);
if (n > x.length) {slideIndex[no] = 1}
if (n < 1) {slideIndex[no] = x.length}
for (i = 0; i < x.length; i++) {
x[i].style.display = "none";
}
x[slideIndex[no]-1].style.display = "block";
}
Thank you for any help
