**Hey there, coding enthusiasts! I could really use some help right now. I am trying to create a smooth image transition effect using Javascript, where one image fades out while the next one fades in seamlessly. As someone who is still relatively new to programming and seeking guidance, how can I achieve this without any noticeable background changes?
I was hoping that the code would smoothly fade between images in a loop. Here is what I have managed to come up with so far.**
======HTML CODE=====
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Javascript Image Transition</title>
====CSS======
<style>
body {
text-align: center;
}
h1 {
color: green;
}
img {
position: absolute;
left: 400px;
}
</style>
</head>
<body>
<div id="scroll-image">
<img src="SnugBear_home.png" class="test"/>
<img src="img.png" class="test"/>
<img src="img2.png" class="test"/>
</div>
=======Javascript Code=======
<script>
startImageTransition();
function startImageTransition() {
var images = document.getElementsByClassName("test");
for ( var i = 0; i < images.length; ++i) {
images[i].style.opacity = 1;
}
var top = 1;
var cur = images.length - 1;
setInterval(changeImage, 3000);
async function changeImage() {
var nextImage = (1 + cur) % images.length;
images[cur].style.zIndex = top + 1;
images[nextImage].style.zIndex = top;
images[cur].style.zIndex = top;
images[nextImage].style.zIndex = top + 1;
top = top + 1;
images[cur].style.opacity = 1;
cur = nextImage;
}
function transition() {
return new Promise(function(resolve, reject) {
var del = 0.01;
var id = setInterval (changeOpacity, 10);
function changeOpacity() {
images[cur].style.opacity -= del;
if (images[cur].style.opacity <= 0) {
clearInterval(id);
resolve();
}
}
})
}
}
</script>
</body>
