Hi I want to replace a div that is already displayed with another Hidden div choosed when i click on one of them(3 other divs(hidden) initially). the 4 links related to the 4 divs and in same way i can do that in each link clicked. below is the code:
<script type="text/javascript">
#4 Id of divs
var models = document.getElementById('models')
var geometry = document.getElementById('geometry')
var assembly = document.getElementById('assembly')
var loads = document.getElementById('loads')
#4 ID OF links (related to each div)
var models1 = document.getElementById('models1')
var geometryy = document.getElementById('geometryy')
var assemblyy = document.getElementById('assemblyy')
var loads1 = document.getElementById('loads1')
geometryy.addEventListener("click", function () {
models.style.display = "none"
loads.style.display = "none"
assembly.style.display = "none"
geometry.style.display = "block"
})
assemblyy.addEventListener("click", function () {
geometry.style.display = "none"
models.style.display = "none"
loads.style.display = "none"
assembly.style.display = "block"
})
loads1.addEventListener("click", function () {
geometry.style.display = "none"
models.style.display = "none"
assembly.style.display = "none"
loads.style.display = "block"
})
models1.addEventListener("click", function () {
models.style.display = "block"
geometry.style.display = "none"
assembly.style.display = "none"
loads.style.display = "none"
})
</script>

what i want :at first the "models" div is shown and the other 3 divs("geometry",assembly","loads") are hidden , so i want when i click on "geometry" div , the first div "models" become hidden and the other divs ("assembly" and "loads" still hidden) and so on if click on assembly... i i want to apply that on every div(because evry div has the 4 links)
But it doesn't give me any result!

Programatically setting images widths based on container width

I have a series of images i'd liike to output per row. I ned these image to take up the ful width of each row in question. The only way I can think to to do this is by calculating the combined widths of the images vs container width. Then use the pecenateg difference to reduce the image widths.
I have this working nearly 100% as expected, but the images do not quite fill the space in some cases. There must be a flaw in my logic as this should always fit the space based on the calculations.
As you can see from the example below, the images do not quite line up in the righthand side. I think the flaw in my logic is on this line return imageWidths + (60 * imgs.length);
Demo: http://jsfiddle.net/rev3tsuf/5/
JS:
function processImageRows(className, containerWidth) {
let imgWidths = getImageWidthCombines(className);
// initiate image width setting if too large for container
if (imgWidths > containerWidth) {
let percent = Math.ceil((containerWidth / imgWidths) * 100);
getImageWidthCombines(className, percent);
}
}
function getImageWidthCombines(className, percent = false) {
// loop through images for given row and return combined width
let imgs = document.querySelectorAll(`#image-wrapper .${ className } img.set-img`);
let imageWidths = 0;
imgs.forEach(function(el, index) {
if (percent) {
// if percentage is set that means we now set the widths as opposed to return their value
el.style.width = `${Math.floor(el.width * (percent / 100))}px`;
} else {
el.style.width = null;
imageWidths += el.offsetWidth;
}
});
// ??? needs 60 added otherwsie doesn't get right percentage.
return imageWidths + (60 * imgs.length);
}
HTML:
<div class="container">
<div class="row row-1">
<div class="col-auto">
<img src="https://via.placeholder.com/400x473.png" />
</div>
... more images
</div>
<div class="row row-2">
<div class="col-auto">
<img src="https://via.placeholder.com/473x473.png" />
</div>
... more images
</div>
<div class="row row-3">
<div class="col-auto">
<img src="https://via.placeholder.com/578x473.png" class="set-img" />
</div>
... more images
</div>
</div>
I also have a window resize event that triggers the above process, but i've left that out of the example in order to keep it simple.
Any help would be greatly appreciated. It's taken me two days to get this far, and half a day stuck on this one issue, now i'm completely stuck with nothing more to try.

EDIT
To adjust your work just customize CSS class as below:
.row {
margin-right: -4px;
margin-left: -4px;
}
.row .col-auto:first-child{
margin-left: 0!important; /* ADDED */
}
.row .col-auto:last-child{
margin-right: 0 !important; /* ADDED */
}
.row .col-auto{
margin-left: auto; /* ADDED */
margin-right:auto; /* ADDED */
}
.col-auto {
padding-right: 4px !important; /* ADDED !important */
padding-left: 4px !important; /* ADDED !important */
padding-bottom: 8px;
position: relative;
overflow: hidden;
cursor: pointer;
}
DEMO with JS CODE your code:
function processImageRows(className, containerWidth) {
let imgWidths = getImageWidthCombines(className);
// initiate image width setting if too large for container
if (imgWidths > containerWidth) {
let percent = Math.ceil((containerWidth / imgWidths) * 100);
getImageWidthCombines(className, percent);
}
}
function getImageWidthCombines(className, percent = false) {
// loop through images for given row and return combined width
let imgs = document.querySelectorAll(`#image-wrapper .${ className } img.set-img`);
let imageWidths = 0;
imgs.forEach(function(el, index) {
if (percent) {
// if percentage is set that means we now set the widths as opposed to return their value
el.style.width = `${Math.floor(el.width * (percent / 100))}px`;
} else {
el.style.width = null;
imageWidths += el.offsetWidth;
}
});
// ??? needs 60 added otherwsie doesn't get right percentage.
return imageWidths + (60 * imgs.length);
}
// this is called after each image load
function checkLoadingProgress() {
let containerWidth = document.getElementById('image-wrapper').clientWidth;
let imgsTotal = 0;
let imgsLoaded = 0;
// loop through rows
['row-1', 'row-2', 'row-3'].forEach(function(el, index) {
imgsTotal = document.querySelectorAll(`#image-wrapper .${el} img.set-img`).length;
imgsLoaded = document.querySelectorAll(`#image-wrapper .${el} img.set-img.image-loaded`).length;
// only process is all images have loaded for the given row
if (imgsLoaded > 0 && imgsLoaded == imgsTotal) {
processImageRows(el, containerWidth);
}
});
// finally all images have loaded. Updated loading class on container
let allImgsTotal = document.querySelectorAll(`#image-wrapper img.set-img`).length;
let allImgsLoaded = document.querySelectorAll(`#image-wrapper img.set-img.image-loaded`).length;
if (allImgsTotal == allImgsLoaded) {
document.getElementById('image-wrapper').classList.add('image-loaded');
document.getElementById('image-wrapper').classList.remove('image-loading');
}
}
// bind onload event to images
let imgs = document.querySelectorAll('img.set-img');
imgs.forEach(function(el, index) {
el.addEventListener('load', function() {
this.classList.add('image-loaded');
checkLoadingProgress();
}, false);

BEFORE EDIT:
From the point you know the container size or use flex box, no need to have js, you can simply use CSS by fixing a container as below:
.flexible-container{
max-height: 100%;
overflow:hidden;
position: relative;
}
And then set img with class w-100 and the below CSS:
.flexible-container img{
position: absolute;
left:50%;
top:50%;
transform: translate(-50%, -50%);
}
Images size will be respected and won't be stretch as the extra height will be hidden by container overflow: hidden;.
With class col so automatic width as you seems to have you are grid, pretty much either use grid directly or customize flex class as below:
.flex-15{
flex:1 1 15% !important;
}
.flex-30{
flex:1 1 30% !important;
}
DEMO:
.row-1, .row-2, .row-3{
height: 20vh;
margin-bottom: 10px;
}
.flexible-container{
max-height: 100%;
overflow:hidden;
position: relative;
}
.flexible-container img{
position: absolute;
left:50%;
top:50%;
transform: translate(-50%, -50%);
margin: 1px;
}
.flex-15{
flex:1 1 15% !important;
}
.flex-30{
flex:1 1 30% !important;

I want to use an event listener to get every element on the page to respond to a keypush - however, I'm having problems replicating the Javascript code for each element, it just won't work.
const input = document.querySelector('input');
document.addEventListener('keydown', logKey);
function logKey(e) {
if(e.code == 'KeyB') {
var tag = document.querySelector('.batman');
tag.classList.toggle('active');
}
}
I want to use a different key - say 'KeyA' for a different element - say '.spiderman'. I've tried replicating the code above with these replacements, but this hasn't worked.
What's the best way to achieve this?

Your forgot to assign each separate div a classname. I added the names for all of them, but only tied in batman and spiderman (b and s keys). Try it out, and you can easily add the rest of them.
const input = document.querySelector('input');
document.addEventListener('keydown', logKey);
function logKey(e) {
if(e.code == 'KeyB') {
var tag = document.querySelector('.batman');
tag.classList.toggle('active');
console.log('B clicked')
}
if (e.code == 'KeyS') {
var tag = document.querySelector('.spiderman');
tag.classList.toggle('active');
console.log('S clicked')
}
}

My jquery slider refresh rate won't update live

I am trying to develop a simple jquery slider, the slier switches between images and text each three seconds by default (var segundos = 3;), the slider has a button which acts as a play/pause action and a menu option which lets you increase or decrease the ammoun of seconds it will switch between images each time. This is done via the classes .resta and .suma(decrease and decrease).
Now, the slider works good but there is a problem, when the segundos variable (segundos means seconds) changes the effect don't take action unless the slider is paused, it won't automatically refresh while theslider is running. It has to go like this: pause slider > change default seconds > play slider > see results
My objective is to make it so it changes the refresh rate while the slider is up and running.
Here is the code:
<script>
$(document).ready(function(){
var segundos = 3000;
var stop = true;
var slideInterval;
$('.play').click(function(){
if (stop == false) {
stop = true;
$('#playpause').text('Play it');
clearInterval(slideInterval);
}
else {
stop = false;
$('#playpause').text('Pause it');
slideInterval = setInterval(swapSlides, segundos);
}
});
function swapSlides(){
//var cs = $('div.currentslide:first');
var cs = $('#polaroid1').children('.currentslide:first');
var ns = cs.next();
if(ns.hasClass('mySlides1')){
cs.removeClass('currentslide');
ns.addClass('currentslide');
}
else{
ns = $('#polaroid1').children('div.mySlides1:first');
cs.removeClass('currentslide');
ns.addClass('currentslide');
}
}
$('.resta').click(function(){
if(segundos > 1000){
segundos = segundos - 1000;
segundoss = (segundos/1000);
$('.segundos').text(" " + segundoss + "s ");
}
});
$('.suma').click(function(){
if(segundos >= 1000 && segundos < 15000){
segundos = segundos + 1000;
segundoss = (segundos/1000);
$('.segundos').text(" " + segundoss + "s ");
}
});
});

It has to go like this: pause slider > change default seconds > play
slider > see results
My objective is to make it so it changes the refresh rate while the
slider is up and running.
That's because you never do anything to your slideInterval when you increase/decrease the slide interval time (segundos).
Solution:
Add function to restart your slideInterval like so:
function _restartSlide() {
clearInterval(slideInterval);
slideInterval = setInterval(swapSlides, segundos);
}

Set multiple div height based on a defined div

How do I make <div A> and <div C> to have same height as <div B> in javascript/jquery?
<div id="wrapper">
<div id="divA"></div>
<div id="divB"></div>
<div id="divC"></div>
</div>
<script>
$('#divA').css('height', $('#divB').innerHeight());
$('#divC').css('height', $('#divB').innerHeight());
</script>

Try
$("#divA, #divC").height($("#divB").height());
$("#divA, #divC").height($("#divB").height());
#divA, #divC {
height: 50px;
width:50px;
background:gold;
}
#divB {
height: 100px;
width:50px;
background:red;
}
div {
display:inline-block;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js">
</script>
<div id="wrapper">
<div id="divA"></div>
<div id="divB"></div>
<div id="divC"></div>
</div>

Try this demo : fiddle
var selDivB = $('#divB').height();
$('#divA, #divC').height(selDivB);
