Forgive me, it's been a while since figuring out anything with jQuery, I need some guidance/help: I'd love to swap an image 00x-a for 00x-b, but not just for a single image, but for many. Once the BTN below an IMG is clicked, I'd love to swap the IMG above for 00x-b while resetting other IMGs to 00x-a.
<div>
<img id="swap_this" src="img-001-a.jpg">
<a class="button">Change-IMG</a>
</div>
<div>
<img id="swap_this" src="img-002-a.jpg">
<a class="button">Change-IMG</a>
</div>
<div>
<img id="swap_this" src="img-003-a.jpg">
<a class="button">Change-IMG</a>
</div>
<script type="text/javascript">
jQuery(document).ready(function($) {
$(".button").click(function(){
$("#swap_this").attr()({
"src":"img-001-b.jpg";
})
})
});
</script>
This should do it. Only the first picture is set to img-001-a.jpg
var arr = ['img-001-a.jpg', 'img-002-a.jpg', 'img-003-a.jpg']
$.each($('.swap_this'), function(index, value) {
if(index == 0) {
$(this).attr('src', arr[0])
console.log($(this).attr('src'));
}
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>

<div>
<img class="swap_this" src="img-002-b.jpg">

Tried to follow up on your answer, but ended up with something else. The below does what I need, but can it be written with "each" or using a for-loop to iterate through? Thx.
// clicking btn_100
$('.btn_100').click(function(e) {
// reset all IMG to version -a.gif..
$(".img_100").attr('src','img-100-a.gif');
$(".img_099").attr('src','img-099-a.gif');
$(".img_098").attr('src','img-098-a.gif');
// set IMG_100 ver -b.gif..
$(".img_100").attr('src','img-100-b.gif');
});
// clicking btn_099
$('.btn_099').click(function(e) {
// reset all IMG to version -a.gif..
$(".img_100").attr('src','img-100-a.gif');
$(".img_099").attr('src','img-099-a.gif');
$(".img_098").attr('src','img-098-a.gif');
// set IMG_100 ver -b.gif..
$(".img_099").attr('src','img-099-b.gif');
});
// and so on..
Maybe this could work…
for(a=1; a<=100; a++) {
// create fns for all btns
$(".btn_" + a).click(function(e) {
// reset all IMG to version -a.gif..
for(i=1; i<=100; i++) {
$(".img_" + i).attr("src","image-" + i + "-a.gif");
}
// set specific IMG to version -b.gif..
$(".img_" + a).attr("src","image-" + a + "-b.gif");
});
}

I've tried to fix this problem for the past 1 hour without success. Basically, once I reach "imageB", I have to click 1 extra time before the image resets back to "imageA". I don't understand why this is happening. Any assistance will be greatly appreciated:
HTML:
<body>
<div class="main-container">
<div class="image-div">
<img width="500px" id="image-holder" src="images/imageA.jpeg" alt="" />
</div>
<button onclick="nextImage()">Next</button>
</div>
<script src="index.js"></script>
</body>
JS:
let imageHolder = document.getElementById("image-holder");
let images = ["images/imageA.jpeg", "images/imageB.jpeg"];
let i = 1;
function nextImage() {
if (i < images.length) {
imageHolder.setAttribute("src", images[i]);
i++;
} else {
i = 0;
}
}
I made a code which can solve your problem, but I think it's a little long, maybe you can find a code more readable on more short than my, anyway here is my solution and it works for me:
everytime when you click in the button, the function give the next item in the array (next source), but if the item is in the end of the array he start again by the first item in the array.
<div class="main-container">
<div class="image-div">
<img width="500px" id="image-holder" src="./img1.png" alt="" />
</div>
<button onclick="nextImage()">Next</button>
</div>
let imageHolder = document.getElementById("image-holder");
let images = ["./img1.png", "./oz.png","./img2.png"];
function nextImage() {
let getSrcAttr = imageHolder.getAttribute("src");
let newSrc =
imageHolder.setAttribute("src",images[(images.indexOf(getSrcAttr))+1]);
if(images.indexOf(getSrcAttr) == (images.length)-1){
newSrc = imageHolder.setAttribute("src",images[0]);
}
}
I am trying to make a script that will take the images from one div element and put it to div rndmImage randomly on button click, I should see images when document is loaded, but the new div where images should go after click must be empty until click heapends. And I need only JavaScript, no jQuery, alse i can not change the html, and it has to work for any number of images. So if you have some ideas that would be great. Here's my code.
window.addEventListener('load', start, false);
function start() {
var butt = document.getElementsByTagName('button')[0];
var rnImg = document.getElementsByClassName('ekran');
var pictures = document.getElementsByTagName('img');
var choose = Math.floor(Math.random()*pictures.length);
butt.addEventListener('click', menjaj, false);
function menjaj(e) {
var new = e.button;
var img = [];
for(var i = 0; i< pictures.length; i++) {
var dodaj = img[i];
img.push(dodaj);
}
//ekran.src = 'slike/' + slike[izbor] + '.jpg';
}
}
<body>
<div class="wrapper">
<div>
<img src="slike/leto1.jpg" alt="leto1">
<img src="slike/leto2.jpg" alt="leto2">
<img src="slike/leto3.jpg" alt="leto3">
<img src="slike/leto4.jpg" alt="leto4">
<img src="slike/leto5.jpg" alt="leto5">
<img src="slike/leto6.jpg" alt="leto6">
<img src="slike/leto7.jpg" alt="leto7">
<img src="slike/leto8.jpg" alt="leto8">
<img src="slike/leto9.jpg" alt="leto9">
</div>
<div>
<button type="button">choose</button>
</div>
<div class="rndmImage"></div>
</div>
</body>
This is a working snippet of your code:
window.addEventListener('load', start, false);
function start () {
var butt = document.getElementsByTagName('button')[0];
var rnImg = document.getElementsByClassName('rndmImage')[0]; //Change selector to existing class and select the first (the only) one
var pictures = document.getElementsByTagName('img');
butt.addEventListener('click', menjaj, false);
function menjaj (e) {
// var new = e.button;// 'new' is reserved word in JS, you can't use it as variable name
// var btn = e.button;// but this line is useless
var choose = Math.floor(Math.random() * pictures.length); //better move this line inside this function to get rundom image every button clicks
var img = document.createElement('img'); //creates new img tag
img.src = pictures[choose].src;
rnImg.innerHTML = ''; //to delete previous image
rnImg.appendChild(img);
// var img = []; //useless lines of code
// for(var i = 0; i< pictures.length; i++) {
// var dodaj = img[i];
// img.push(dodaj);
// }
//ekran.src = 'slike/' + slike[izbor] + '.jpg';
}
}
welcome to StackOverflow!
I would first hide the .wrapper > div img as that will prevent the images to show, then, append a data-pos to help select the position and simply randomize them and pick the src to show on the placeholder
and remember that you have a <div> as placeholder, so you can't assign src, only if you change it to <img>
so, something like this 😊
function chooseImg() {
// get total images available
var totalImages = document.querySelectorAll('.wrapper > div img').length
log('totalImages', totalImages)
// get a random position
var rndPosition = Math.floor(Math.random() * totalImages)
log('rndPosition', rndPosition)
// get hold of the image for such position
var rndImage = document.querySelector('.wrapper > div img[data-pos="' + rndPosition + '"]')
log('rndImage', rndImage)
// assign the source to the DIV
document.querySelector('.rndmImage').style = 'background-image: url("' + rndImage.src + '")'
}
function log(txt, obj) {
console.log(txt, obj)
}
.wrapper > div img {
display: none;
}
.rndmImage {
background-size: contain;

You can do this with plain javascript like this:
document.querySelector("button").addEventListener("click", () => {

If you're able to use randojs, you can even simplify the randomness and make it all cryptographically secure like this:
document.querySelector("button").addEventListener("click", () => document.querySelector(".rndmImage").innerHTML = rando(document.querySelectorAll(".wrapper img")).value.outerHTML);

Try this:

my javascript file
imgcount = 0;
function changeImage() {
document.getElementById("imagechange").src =
"https://picsum.photos/200/" + (300 + imgcount);
imgcount++;
}
everytime you click button you get a new image
I'm trying to work on a simple slider by Javascript.
It would be great if you could give me a little help.
Thank you.
HMTL below
<div class="carousel-container">
<div class="auto-slide">
<img src="img/cheetah.png" alt="">
<img src="img/elephant.png" alt="">
<img src="img/penguin.png" alt="">
<img src="img/zebra.png" alt="">
</div>
</div>
Javascript below
// auto
const slideBox = document.querySelector(".auto-slide")
const autoSlideImages = document.querySelectorAll(".auto-slide img");
// counter
let count = 0;
function autoSlide(){
if(count < autoSlideImages.length - 1){
count++;
console.log("hi.");
}else{
count = 0;
console.log("bye");
}
slideBox.innerHTML = "<img" + autoSlideImages[count]; + ">";
}
setInterval("autoSlide()", 1500);
Thank you again.
You can use,
slideBox.innerHTML = "<img src='" + autoSlideImages[count].src + "'>";
I am sure this will fix your issue!
If you want to do this with the better way you can use my CODEPEN DEMO
replace
setInterval("autoSlide()", 1500);
to
setInterval(autoSlide, 1500);
I want to change an image to some other image when i click on the object. the code is stacked in the following order:
<li><img><some text></img></li>
<li><img><some text></img></li>
<li><img><some text></img></li>
<li><img><some text></img></li>
<li><img><some text></img></li>
What I wish to do is, when I click on the <li> i want to change the image to a coloured version of the image, i.e. some other image. Now, I know I can use JQuery/JS to accomplish it. But I don't want a huge amount of JS code to accomplish something so simple.
Can it be done using something simpler? Like pseudo selectors? .active class?
I cannot seem to think of it.
To change image onclik with javascript you need to have image with id:
<p>
<img alt="" src="http://www.userinterfaceicons.com/80x80/minimize.png"
style="height: 85px; width: 198px" id="imgClickAndChange" onclick="changeImage()"/>
</p>
Then you could call the javascript function when the image is clicked:
function changeImage() {
if (document.getElementById("imgClickAndChange").src == "http://www.userinterfaceicons.com/80x80/minimize.png"){
document.getElementById("imgClickAndChange").src = "http://www.userinterfaceicons.com/80x80/maximize.png";
} else {
document.getElementById("imgClickAndChange").src = "http://www.userinterfaceicons.com/80x80/minimize.png";
}
}
This code will set the image to maximize.png if the current img.src is set to minimize.png and vice versa.

How about this? It doesn't require so much coding.
$(".plus").click(function(){
$(this).toggleClass("minus") ;
})
.plus{
background-image: url("https://cdn0.iconfinder.com/data/icons/ie_Bright/128/plus_add_blue.png");
width:130px;
height:130px;
background-repeat:no-repeat;
}
.plus.minus{
background-image: url("https://cdn0.iconfinder.com/data/icons/ie_Bright/128/plus_add_minus.png");
width:130px;
height:130px;
background-repeat:no-repeat;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="plus">CHANGE</div>
If your images are named you can reference them through the DOM and change the source.
document["imgName"].src="../newImgSrc.jpg";
or
document.getElementById("imgName").src="../newImgSrc.jpg";
The most you could do is to trigger a background image change when hovering the LI. If you want something to happen upon clicking an LI and then staying that way, then you'll need to use some JS.
I would name the images starting with bw_ and clr_ and just use JS to swap between them.
example:
$("#images").find('img').bind("click", function() {
var src = $(this).attr("src"),
state = (src.indexOf("bw_") === 0) ? 'bw' : 'clr';
(state === 'bw') ? src = src.replace('bw_','clr_') : src = src.replace('clr_','bw_');
$(this).attr("src", src);
});

Here, when clicking next or previous, the src attribute of an img tag is changed to the next or previous value in an array.
<div id="imageGallery">
<img id="image" src="http://adamyost.com/images/wasatch_thumb.gif" />
<div id="previous">Previous</div>
<div id="next">Next</div>
</div>
<script src="http://code.jquery.com/jquery-1.11.0.min.js"></script>

$( document ).ready(function() {
var images = [
"http://placehold.it/350x150",
"http://placehold.it/150x150",
"http://placehold.it/50x150"
];
var imageIndex = 0;
$("#previous").on("click", function(){
imageIndex = (imageIndex + images.length -1) % (images.length);
$("#image").attr('src', images[imageIndex]);
});
$("#next").on("click", function(){
imageIndex = (imageIndex+1) % (images.length);
$("#image").attr('src', images[imageIndex]);
});
$("#image").attr(images[0]);
});
</script>
I was able to implement this by modifying this answer: jQuery array with next and previous buttons to scroll through entries
If you don't want use js, I think, you can use instead of img and then use css like
a {
background: url('oldImage.png');
}
a:visited {
background: url('newImage.png');
}
EDIT: Nope. Sorry it works only for :hover
You can try something like this:
CSS
div {
width:200px;
height:200px;
background: url(img1.png) center center no-repeat;
}
.visited {
background: url(img2.png) center center no-repeat;
}
HTML
<div href="#" onclick="this.className='visited'">
<p>Content</p>

IE uses attachEvent instead of addEventListener.
You may want to use a cross-browser Javascript library such as jQuery to handle these issues (and many more) for you.
