Image slider - slide animation - jQuery

Ok, i'm stuck.
I need to implement animation on my slider over the jQuery. So far i done arrows (navigation) functionality but, can't figure it out how to add sliding effect (1, 2 seconds) after clicking the "next" and "prev" buttons.
Anyone have idea?
$(document).ready(function() {
$('.next').on('click', function() {
var currentImg = $('.current');
var nextImg = currentImg.next();
if(nextImg.length == 0) {
nextImg = $('.slider-secondary img').first();
}
currentImg.removeClass('current');
nextImg.addClass('current');
});
$('.previous').on('click', function() {
var currentImg = $('.current');
var prevImg = currentImg.prev();
if(prevImg.length == 0) {
prevImg = $('.slider-secondary img').last();
}
currentImg.removeClass('current');
prevImg.addClass('current');
});
});
<div class="container">
<div class="slider-primary">
<img src="Assets/arrow-blue-left.png" class="previous" alt="Prev">
<div class="slider-secondary">
<img src="Assets/slider-image-1.jpg" class="current">

Thanks a lot guys for your help and references. I appreciate it.
Slider must not be automatic, it can work only on arrows(navigation) click, which are (and must be) images/icons.
Also it's not alowed to use any existing scripts, plugins, etc.. so i tried to implement some further logic having in mind and considering all of the conditions above.
It's actually one part of the code test. And must be in jQuery in which i don't flow so well obviously.
Here is the css part also
*{
margin: 0;
padding: 0;
}
.container, .slider-primary{
width:100%;
margin:auto;
overflow: hidden;
position: relative;
}
.slider-secondary{
width:100%;
height:600px;
position:relative;
overflow:hidden;
float:left;
}
.slider-secondary img{
display:none;
width:100%;
height:100%;
}
.slider-secondary img.current{
display:inline-block;
}
.previous, .next{
float:left;
cursor: pointer;
position: absolute;
top: 45%;
width: 30px;
height: 40px;
}
.previous{
margin-left:35px;
z-index:100;
}
.next{
margin-left:-65px;
z-index:100;
}

You can use jQuery animate() Method. Here is the link to the documentation.
But I would suggest using any jQuery lightweight library for the same.
You can go for Responsive and Flexible Mobile Touch Slider - Swiper
Demo of the same!

Here is one working example. Hope it'll help you. for the full reference visit codepen
$('.slider').each(function() {
var $this = $(this);
var $group = $this.find('.slide_group');
var $slides = $this.find('.slide');
var bulletArray = [];
var currentIndex = 0;
var timeout;
function move(newIndex) {
var animateLeft, slideLeft;
advance();
if ($group.is(':animated') || currentIndex === newIndex) {
return;
}
bulletArray[currentIndex].removeClass('active');
bulletArray[newIndex].addClass('active');
if (newIndex > currentIndex) {
slideLeft = '100%';
animateLeft = '-100%';
} else {
slideLeft = '-100%';
animateLeft = '100%';
}
$slides.eq(newIndex).css({
display: 'block',
left: slideLeft
});
$group.animate({
left: animateLeft
}, function() {
$slides.eq(currentIndex).css({
display: 'none'
});
$slides.eq(newIndex).css({
left: 0
});
$group.css({
left: 0
});
currentIndex = newIndex;
});
}
function advance() {
clearTimeout(timeout);
timeout = setTimeout(function() {
if (currentIndex < ($slides.length - 1)) {
move(currentIndex + 1);
} else {
move(0);
}
}, 4000);
}
$('.next_btn').on('click', function() {
if (currentIndex < ($slides.length - 1)) {
move(currentIndex + 1);
} else {
move(0);
}
});
$('.previous_btn').on('click', function() {
if (currentIndex !== 0) {
move(currentIndex - 1);
} else {
move(3);
}
});
$.each($slides, function(index) {
var $button = $('<a class="slide_btn">•</a>');
if (index === currentIndex) {
$button.addClass('active');
}
$button.on('click', function() {
move(index);
}).appendTo('.slide_buttons');
bulletArray.push($button);
});
advance();
});

Try below way.
I have created a demo for you.

How can I hide all slides and display the current one in JavaScript?

I'm creating a slider in Vanilla JavaScript.
I have a basic foundation.
Right now I'm not sure how to hide all of the other slides, and display only the current one. Then on the next/prev, show show the next slide, and hide the one that was before.
I have tried few things, but neither did work.
Here is the codepen: https://codepen.io/Aurelian/pen/LBGWpd?editors=0010
// Problem: Make the slides slide one after another
// and make the buttons work prev and next to bring prev or next slide
// Solution
// Select all slides
// On next/prev, get the left/right animate from 0 to 100 or from 0 to -100%
// On button press, get the prev/next parent node
// Add active class on the shown
// Solution Part 2
// Select all slides
// Get the length of the slides
// Display none on every slideItem
// Get the current slide
// Display block/flex on current slide
// On next, advance the slider index by 1
// On prev, advance the slider index by -1
// Make the slider slide every 3sec with setInterval
// Even listener on slider mousehover, stop the autoslide and add "PAUSED" HTML - add
// On live the slder, unpause and remove the HTML "PAUSED"
document.addEventListener('DOMContentLoaded', function() {
var slider = document.querySelector(".slider"),
sliderList = document.querySelector(".slider__list"),
sliderItems = document.querySelectorAll(".slider__item"),
sliderBtnPrev = document.querySelector(".slider__buttons--prev"),
sliderBtnNext = document.querySelector(".slider__buttons--next"),
sliderItemsLength = sliderItems.length,
currentIndex = 0,
isPaused = false;
function prevSlide() {
sliderItems[currentIndex].classList.remove('is-active');
currentIndex = (currentIndex + sliderItemsLength - 1) % sliderItemsLength;
sliderItems[currentIndex].classList.add('is-active');
}
function nextSlide() {
sliderItems[currentIndex].classList.remove('is-active');
currentIndex = (currentIndex + 1) % sliderItemsLength;
sliderItems[currentIndex].classList.add('is-active');
}
function advance() {
isPaused = false;
if ((isPaused = false) = 1) {
setInterval(function() {
nextSlide();
}, 3000);
}
}
sliderBtnPrev.addEventListener('click', function() {
prevSlide();
});
sliderBtnNext.addEventListener('click', function() {
nextSlide();
});
slider.addEventListener('mouseover', function() {
isPaused = true;
});
slider.addEventListener('mouseout', function() {
isPaused = false;
});
advance();
// On press next, change slide
// sliderItems.forEach(function(sliderItem) {
// sliderItem.style.display = "none";
// });
// function prevSlide() {
// console.log('prev slide');
// }
// function nextSlide() {
// console.log('next slide');
// // if (currentIndex) {
// // console.log(sliderItems[currentIndex])
// // }
// // sliderItemsLength.push[1];
// // currentIndex + 1;
// // console.log(currentIndex < (sliderItemsLength + 1));
// // console.log(sliderItems[currentIndex + 1])
// // if (sliderItemsLength < -1) {
// // sliderItemsLength++;
// // }
// // if (currentIndex < (sliderItemsLength + 1)) {
// // sliderItems[currentIndex].classList.add('is-active');
// // }
// // if (numbers.length > 3) {
// // numbers.length = 3;
// // }
// // myArray[myArray.length - 1] + 1
// if (currentIndex < (sliderItemsLength + 1)) {
// sliderItems[currentIndex].classList.add('is-active');
// currentIndex++;
// } else {
// sliderItems.style.display = "none";

You need to hide all slides by default display: none then define a class is-active to change the display to flex
Start counting from -1
The formula to calculate the next slide is :
(currentIndex + 1) % sliderItemsLength
The formula to calculate the prev slide is :
(currentIndex + sliderItemsLength - 1) % sliderItemsLength
document.addEventListener('DOMContentLoaded', function() {
var sliderList = document.querySelector(".slider__list"),
sliderItems = document.querySelectorAll(".slider__item"),
sliderBtnPrev = document.querySelector(".slider__buttons--prev"),
sliderBtnNext = document.querySelector(".slider__buttons--next"),
sliderItemsLength = sliderItems.length,
currentIndex = -1;
function prevSlide() {
sliderItems[currentIndex].classList.remove('is-active');
currentIndex = (currentIndex + sliderItemsLength - 1) % sliderItemsLength;
sliderItems[currentIndex].classList.add('is-active');
}
function nextSlide() {
if (currentIndex > 0) sliderItems[currentIndex].classList.remove('is-active');
else sliderItems[0].classList.remove('is-active');
currentIndex = (currentIndex + 1) % sliderItemsLength;
sliderItems[currentIndex].classList.add('is-active');
}
sliderBtnPrev.addEventListener('click', function() {
prevSlide();

When i changed position of functions why doesn't it work with javascript closure?

I'm a new javascript, let me direct to the point. I have heard that we have to avoid global variables as much as we can, so, i learn to use closure for make sure that variables can not access to each other.
I have slideShow function which is on the top and toggleMenu function on the bottom, these functions are work fine in my webpage.
My problems is when i changed position of functions, slideShow function to the bottom and toggleMenu function to the top, my webpage it looks not fine, doesn't work properly
May be there is something that i don't know? or i did something wrong? if any one would give me some advices i would appreciate that, thank you.
Here is original code
var slideShow = (function () {
var slideImages = document.getElementsByClassName("slide");
var leftSide = document.getElementById("arrow-left");
var rightSide = document.getElementById("arrow-right");
var slideBullets = document.getElementsByClassName("bullets");
var current = 0;
function reset() {
for (let i = 0; i < slideImages.length; i++) {
slideImages[i].style.display = 'none';
slideBullets[i].classList.remove("clicked");
}
};
function showImages() {
for (let i = 0; i < slideImages.length; i++) {
slideImages[0].style.display = 'block';
slideBullets[current].classList.add("clicked");
}
};
function arrowSlide() {
leftSide.addEventListener("click", function () {
reset();
if (current === 0) {
current = slideImages.length;
}
slideImages[current - 1].style.display = 'block';
current--;
slideBullets[current].classList.add("clicked");
});
rightSide.addEventListener("click", function () {
reset();
if (current === slideImages.length - 1) {
current = - 1;
}
slideImages[current + 1].style.display = 'block';
current++;
slideBullets[current].classList.add("clicked");
});
};

return {

arrowSlide: arrowSlide(),
showBulletsImages: showBulletsImages(),
autoSlide: autoSlide()
};
})();

The issue seems to be with this
return {
toggleMenu: toggleMenu()
};
inside the toggleMenu immediately invoking function . This IIFE does not have any toggleMenu function
Beside return like
return {
reset: reset(),
showImages: showImages(),
arrowSlide: arrowSlide(),
showBulletsImages: showBulletsImages(),
autoSlide: autoSlide()
};
is not appropriate ,replace it with the following
There is no reason tha slideShow has to IIFE
return {
reset: reset,
showImages: showImages,
arrowSlide: arrowSlide,
showBulletsImages: showBulletsImages,
autoSlide: autoSlide
};
Here is a working demo at stackblitz

Carousel Images Same Height

I have an image/video carousel and I'm having trouble keeping all the content in the carousel the same height.
When you click on the thumbnails, the main image heights don't match up.
How do I keep everything the same height, yet responsive at the same time?
(I added some pictures to show what I mean)
Here's the codepen.
Edit: I want to keep the main images shown in the carousel the same height, not the thumbnails.
$(document).ready(function() {
// get all images loaded
var images = $(".chair-class");
// thumbnails containers
var thumbnailContainer = $("#thumbnails");
var iframe1 = $('#sketchfab-iframe-1')[0];
var iframe2 = $('#sketchfab-iframe-2')[0];
var player1 = $f(iframe1);
var player2 = $f(iframe2);
// generate thumbnail images
generateThumbnails(images, thumbnailContainer);
// listeners for controls arrows
$(".prev-next-button").on("click", function() {
player1.api('pause');
player2.api('pause');
// get the images
var currentImageIndex = images.index($(".chair-class[data-active=true]"));
var isPrevious = $(this).hasClass("previous");
var nextIndex;
if (isPrevious) {
if (currentImageIndex === 0) {
nextIndex = images.length - 1;
}
if (currentImageIndex > 0) {
nextIndex = currentImageIndex - 1;
}
} else {
if (currentImageIndex === images.length - 1) {
nextIndex = 0;
}
if (currentImageIndex < images.length - 1) {
nextIndex = currentImageIndex + 1;
}
}
// remove any active class from images
images.removeClass("active").attr('data-active', "false");
// get the next active image and add active class to that next current image
var $nextImage = $(images[nextIndex]);
var iframeId = $nextImage.data('iframe');
if (iframeId) {
$(images[nextIndex]).attr('data-active', "true");
$('.sketchfab-iframe').removeClass('active');
$('#' + iframeId).addClass('active');
} else {
$(images[nextIndex]).addClass("active").attr('data-active', "true");
$('.sketchfab-iframe').removeClass('active');
}
});

event.preventDefault();
var images = $(".chair-class");

It's fixed by setting all the image height to 70vh.
Guess something is not working with StackOverflow Fiddle.

I made an image slider but I have a problem. İf you click the next button, it doesn't hide the image on the left side of the slider.
The code is here :

HTML:
<section id="slider">
<div class="arrow">
<
>
</div>
<div class="slider">
<ul>
<li class="slides"><img src="resimler/resim1.jpg"></li>
<li class="slides"><img src="resimler/resim2.jpg"></li>
<li class="slides"><img src="resimler/resim3.jpg"></li>
<li class="slides"><img src="resimler/resim4.jpg"></li>
</ul>
</div>
</section>
CSS:
section#slider {
margin-left: 150px;
border: 3px solid #333;
width: 1004px;
height: 575px;
position: relative;
}
div.slider {
overflow: hidden;
width: 960px;
}
div.slider ul {
list-style-type: none;
overflow: hidden;
}
div.slider ul li {
width: 960px;
float: left;
}
div.slider ul li img {
width: 960px;
}
div.arrow {
font-size: 50px;
position: absolute;
top: 40%;
}
div.arrow a {
text-decoration: none;
background-color: #333;
color: #999;
display: inline-block;
width: 35px;
height: 70px;
line-height: 70px;
}
div.arrow a:nth-child(1) {
margin-left: 20px;
padding-left: 3px;
}
div.arrow a:nth-child(2) {
margin-left: 870px;
padding-left: 3px;
}
jQuery:
$(document).ready(function() {
var liWidth = $('div.slider ul li').width();
var toplamLi = $('div.slider ul li').length;
var toplamWidth = liWidth * toplamLi;
var liDeger = 0;
$('div.slider ul').css({
width: toplamWidth + "px"
});
$('div.arrow a:nth-child(2)').click(function() {
if (liDeger < toplamLi - 1) {
liDeger++;
toplamWidth = liDeger * liWidth;
$('div.slider ul').animate({
marginLeft: '-' + toplamWidth + "px"
}, 500);
}
return false;
});
$('div.arrow a:nth-child(1)').click(function() {
if (liDeger > 0) {
liDeger--;
toplamWidth = liDeger * liWidth;
$('div.slider ul').animate({
marginLeft: '-' + toplamWidth + "px"
}, 500);
}
return false;
});
});

Changes done only to CSS:
1.
div.slider ul {
margin: 0; padding: 0; //added
}
and 2.
div.slider {
margin: 14px auto 0; //added
}
rest is same
$(document).ready(function() {
var liWidth = $('div.slider ul li').width();
var toplamLi = $('div.slider ul li').length;
var toplamWidth = liWidth * toplamLi;
var liDeger = 0;
$('div.slider ul').css({
width: toplamWidth + "px"
});
$('div.arrow a:nth-child(2)').click(function() {
if (liDeger < toplamLi - 1) {
liDeger++;
toplamWidth = liDeger * liWidth;
$('div.slider ul').animate({
marginLeft: '-' + toplamWidth + "px"
}, 500);
}
return false;
});
$('div.arrow a:nth-child(1)').click(function() {
if (liDeger > 0) {
liDeger--;
toplamWidth = liDeger * liWidth;
$('div.slider ul').animate({
marginLeft: '-' + toplamWidth + "px"
}, 500);
}
return false;
});
});

The easiest would be to keep track of which image you are showing, and hide the rest by CSS. You already know the index of the list item that contains it (liDeger), so you can use that to show the correct image and hide all the others.
The important part is that you want to show the new image as soon as the sliding starts, but only hide the previous one after the sliding ends.
So for example the "next" arrow:
$('div.arrow a:nth-child(2)').click(function() {
if (liDeger < toplamLi - 1) {
liDeger++;
// Add "active" class to next image
var activeLi = $('.slider li').eq(liDeger);
activeLi.addClass('active');
toplamWidth = liDeger * liWidth;
$('div.slider ul').animate({
marginLeft: '-' + toplamWidth + "px"
}, 500, function() {
// Remove "active" class from previous image after the animation
activeLi.prev().removeClass('active') ;
});
}
return false;
});
And the "previous" arrow goes the other way
$('div.arrow a:nth-child(1)').click(function() {
if (liDeger > 0) {
liDeger--;
// Add "active" class to previous image
var activeLi = $('.slider li').eq(liDeger);
activeLi.addClass('active');
toplamWidth = liDeger * liWidth;
$('div.slider ul').animate({
marginLeft: '-' + toplamWidth + "px"
}, 500, function() {
// Remove "active" class from next image after the animation
activeLi.next().removeClass('active') ;
});
}
return false;
});
Then all you need is some CSS to hide everything but the active image:
div.slider ul li {
visibility: hidden;
}
div.slider ul li.active {
visibility: visible;
}
And add a "active" class to the first list item in the HTML:
<div class="slider">
<ul>
<li class="slides active"><img src="resimler/resim1.jpg"></li>
...
</div>
