I want to make a lot of slides in a one-page scrolling site. A neat way to do this was with a code from Stano. My problem is that this code was only meant to occur once per page. In order to make it fit my needs I made it into this fiddle. I realized that this would accumulate very fast into some rather messy coding if I had 20+ of these:
$(document).ready(function() {
var divs = $('.divs>div');
var now = 0; // currently shown div
divs.hide().first().show(); // hide all divs except first
$(".next").click(function() {
divs.eq(now).hide();
now = (now + 1 < divs.length) ? now + 1 : 0;
divs.eq(now).show(); // show next
});
$(".prev").click(function() {
divs.eq(now).hide();
now = (now > 0) ? now - 1 : divs.length - 1;
divs.eq(now).show(); // show previous
});
});
Is there any way to create a common ID/class for the divs and clickers (previous, next) or a container that ensures that the slider functions by itself without interrupting other sliders?
For example creating a variable with the ID of the container
var test = $('.container').attr('id') )
Implementing the ID in the divs
var divs = $(test).attr( 'id',$(test).attr('id') );
Implementing the ID in the next (and prev), so that when they are being clicked they will only affect the divs with the same ID
$(".next",test).click(function () {...
Maybe have a wrapper with a specific ID where the 3 divs (divs, prev and next) are includes and tell the script that they need to be in the same wrapper in order to affect each other.
<div ID="wrap1">
<div class="prev"></div>
<div class="next"></div>
<div class="divs"></div>
</div>
I do not know how the script will change. Maybe including .child() or .parent()?
I am very new at java scripting and hope that my question is understood properly. Please let me know if there is anything that needs to be clarified.
Check my code, each slider has now a function at document ready, not mixing thing around, and a jquery higher version was used.
$(document).ready(function () {
function FirstSlider(){
var divs = $('.div1>div');
var now = 0; // currently shown div
console.log(divs);
divs.hide().first().show(); // hide all divs except first
$(".nex1").click(function () {
divs.eq(now).hide();
now = (now + 1 < divs.length) ? now + 1 : 0;
divs.eq(now).show(); // show next
});
$(".pre1").click(function () {
divs.eq(now).hide();
now = (now > 0) ? now - 1 : divs.length - 1;
divs.eq(now).show(); // show previous
});
}
function SecondSlider(){
var divs = $('.div2>div');
var now = 0; // currently shown div
divs.hide().first().show(); // hide all divs except first
$(".nex2").click(function () {
divs.eq(now).hide();
now = (now + 1 < divs.length) ? now + 1 : 0;
divs.eq(now).show(); // show next
});
$(".pre2").click(function () {
divs.eq(now).hide();
now = (now > 0) ? now - 1 : divs.length - 1;
divs.eq(now).show(); // show previous
});
}
FirstSlider();
SecondSlider();
});

I am trying to make all my divs the same height even if the browser is resized. I have 4 icon boxes. each box has an icon, a title, and a description. I want to make all of them same size. that means if the highest height of the icon container div is 100px all icon holder div will be 100px. the following code is working but if I resize the browser some time the height of the container divs is much bigger than the actual height. what I am doing wrong? (Note the resize will only happen screen size above 767px) thanks
function allSameHeight(sameSec, sameImg, sameTitle, sameDesc) {
jQuery(sameSec).each(function () {
let highestImg = 0;
let highestTitle = 0;
let highestTxt = 0;
jQuery(sameSec).find(sameImg).each(function () {
if (jQuery(this).height() > highestImg) {
highestImg = jQuery(this).height();
}
});
jQuery(sameSec).find(sameTitle).each(function () {
if (jQuery(this).height() > highestTitle) {
highestTitle = jQuery(this).height();
}
});
jQuery(sameSec).find(sameDesc).each(function () {
if (jQuery(this).height() > highestTxt) {
highestTxt = jQuery(this).height();
}
});
if (jQuery(window).width() > 768) {
jQuery(sameSec).find(sameImg).css("min-height", highestImg);
jQuery(sameSec).find(sameTitle).css("min-height", highestTitle);
jQuery(sameSec).find(sameDesc).css("min-height", highestTxt);
} else {
jQuery(sameSec).find(sameImg).css("min-height", "auto");
jQuery(sameSec).find(sameTitle).css("min-height", "auto");
jQuery(sameSec).find(sameDesc).css("min-height", "auto");
}
});
}
Give a class to all four items. I've used myItem for instance.
const setHeights = () => {
let highestHeight = 0;
//Loop through all elements and get the highest height
$('.myItem').each((index, element) => {
if($(element).outerHeight() > highestHeight) {
highestHeight = $(element).outerHeight();
}
});
//Set the height of all elements to highest
$('.myItem').height(highestHeight);
};
$(window).resize(() => {
//Run each time window is resized
setHeights();
});
.myItem {
width: 25%;
color: white;
float: right;
}
.one {
background: red;
}
.two {
background: blue;
}
.three {
background: purple;
}
.four {
background: orange;
}
h3 {
word-wrap: break-word;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div>
<button onclick="setHeights()">Make them equal</button>
</div>
<div class="myItem one">
<h3>
aaaaaaaaaaaaaaaaa
aaaaaaaaaaaaaaaaa

</div>
<div class="myItem two">
<h3>

</div>
<div class="myItem three">

</h3>
</div>
<div class="myItem four">
<h3>

ddddddddddd
ddddddddddddd
ddddddddddddddd
ddddddddddddddddd
</h3>
</div>
For this case there are multiple approaches, I'll mention the two most common (in my opinion):

I have slider and when i mouseover on slider play button is displaying, but slider images are inside a tag and when play button is not hidden i can't click on images inside a tag. i tried set same z-index for both (slider images and play button) but still not working
i need to click on play button when it shown and go to link placed bottom of this play button
if it is possible please help, and sorry for my bad english.
Main question: how can i click on play button with and redirect to link placed inside a tag?

There are a few ways to get around this problem.
One would involve getting rid of the anchor tags altogether, grouping each image inside a single container and assigning a click event listener to each one to ultimately open the link. If you then add another click listener to the arrow button which executes event.preventDefault(); the click event will be passed through to the object below - the <div> including your image.
If you want to keep the anchor tags, things are a little tricky. Luckily there are some helpful JavaScript functions, foremost document.elementsFromPoint(x,y).
If you feed the current mouse coordinates to this function - e.g. by clicking on the arrow button - it will return an array of objects below this point.
This array contains the anchor element in the background, so it's just a matter of picking it out of the array, get the link assigned to it and open it using the window.open() command.
Here's an example:
function bid(n) {
return document.getElementById(n)
}
let sliderPlayButtonContainer = bid('slider-play-button-container');
let sliderPlayButton = bid('slider-play-button');
sliderPlayButtonContainer.addEventListener('click', (event) => {
var list = document.elementsFromPoint(event.clientX, event.clientY)
var anchorElement = list.find(element => element instanceof HTMLImageElement && element.className == 'slide-img').parentElement;
window.open(anchorElement.href, anchorElement.target);
});
function showSliderPlayButton() {
sliderPlayButton.style.transform = "scale(5)";
sliderPlayButton.style.opacity = "1";
sliderPlayButton.style.transition = "250ms";
}
sliderPlayButtonContainer.addEventListener('mouseover', () => {
showSliderPlayButton();
});
#slider-play-button-container {
position: absolute;
z-index: 2;
left: 0;
right: 0;
text-align: center;
cursor: pointer;
}
#slider-play-button {
position: relative;
top: 25vh;
width: 2vw;
opacity: 1;
}
.slide-img {
width: 100%;
height: 55vh;
object-fit: cover;
border-radius: .7vw;
overflow: hidden;
}

parentElement property helped a lot to solve my problem
playButtonATagHref = sliderImage[imgOffset].parentElement.href;
sliderPlayButton.addEventListener('click',()=>{

I am after creating a drop down page like on my examples below:
This is how I would like it to show when the arrow on the side is cliked.
How would I make something like this and is there any examples any where for me to study to help me make this ?
If you can use jquery you can play with hasClass, addClass and removeClass to change the height of the submenu
Working Demo.
$(".btn").click(function() {
if ($(".menu").hasClass("dropped")) {
$(".menu").removeClass("dropped");
} else {
$(".menu").addClass("dropped");
}
});
.menu {
height: 0;
overflow: hidden;
transition: all 0.5s ease 0s;
}
.dropped {
height: inherit;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<button class="btn">
Dropdown
</button>
<div class="menu">
<p>Stufss...</p>
<p>Stufss...</p>
<p>Stufss...</p>
<p>Stufss...</p>
<p>Stufss...</p>
<p>Stufss...</p>
</div>
With 3 div elements you can get a result like the one pictured. From the picture it looks like one div is wrapping around two other div elements, a div element that already has some information and a div element that will grow/shrink in size through appending/removing elements when the user presses the dropdown button.
Here is a working example:
var extraInformation = document.getElementById('infoLong');
var dropdown = document.getElementById('dropdown');
// The extra info that will be appended into the infoLong div
var someHeading = document.createElement('h4');
someHeading.innerHTML = 'Detailed Game Information';
someHeading.style.background = '#C58AC5';
var teamOneInfo = document.createElement('p');
teamOneInfo.innerHTML = 'Team 1: Lost';
teamOneInfo.style.background = '#FF516B';
var teamTwoInfo = document.createElement('p');
teamTwoInfo.innerHTML = 'Team 2: Won';
teamTwoInfo.style.background = '#3FBFBF';
// Should add more detailed information when the dropdown button
// is pressed only if the infoLong div is empty
dropdown.addEventListener('click', function(){
if(extraInformation.children.length === 0){
extraInformation.appendChild(someHeading);
extraInformation.appendChild(teamOneInfo);
extraInformation.appendChild(teamTwoInfo);
}else{
while(extraInformation.firstChild){
extraInformation.removeChild(extraInformation.firstChild);
}
}
});
#infoShort {
background: #3FBFBF;
}
p {
margin: 0;
}
h4 {
margin: 0;
}
<div id='gameInfoContainer'>
<div id='infoShort'>
<h3>Game Summary</h3>
<button id='dropdown'>Dropdown</button>
</div>
<div id='infoLong'></div>
</div>
I want to add and remove classes depending on whether the user scrolls down or up. So far I tried this with wheelDelta event. There is no scrollbar, the page uses 100vw and 100vw with overflow hidden. I want to achieve something similar to this: http://www.sound-of-change.com/#/intro/.
HTML
<div id="wrapper">
<div class="item-1"></div>
<div class="item-2"></div>
<div class="item-3"></div>
<div class="item-4"></div>
</div>
CSS
#wrapper {
width:100vw;
height:100vh;
overflow:hidden;
}
So whenever a user scrolls I want to be able to add and remove classes for each time someone scrolls down or up.
For example, the user is able to scroll down or up 4 times. And actually goes up or down (depending on the scroll direction) in the actions list.
Default: Situation 0
Scroll down once -> Situation 1
Scroll down again -> Situation 2
But if the users scrolls up now -> Situation 1 will be triggered
Scroll down again -> Back to situation 2
Scroll down again -> Situation 3
So far I only managed to trigger an event on scroll up and down, but that's it. Example:
$('body').bind('mousewheel', function(e){
if(e.originalEvent.wheelDelta /120 > 0) {
$(".cd-background-wrapper").css({'-webkit-filter': "grayscale(0%)"});
$(".logo-text").removeClass("hide-logo");
$(".logo-img").removeClass("come-closer");
}
else{
$(".cd-background-wrapper").css({'-webkit-filter': "grayscale(100%)"});
$(".logo-text").addClass("hide-logo");
$(".logo-img").addClass("come-closer");
}
});
Use a counter to know which situation you are, something like this:
var count = 1;
$("body").on('mousewheel', function(e) {
if (e.originalEvent.wheelDelta / 120 > 0) {
count -= 1;
} else {
count += 1;
}
if (count < 1) count = 1;
if (count > 4) count = 4;
switch (count) {
case 1:
// do something
break;
case 2:
// do something
break;
case 3:
// do something
break;
case 4:
// do something
break;
}
// Just a example that it works
$("#wrapper").attr("data-slide", count);
});
body {
margin: 0;
}
[data-slide="1"] {
background-color: red;
}
[data-slide="2"] {
background-color: green;
}
[data-slide="3"] {
background-color: blue;
}
[data-slide="4"] {
background-color: orange;
}
#wrapper {
width: 100vw;
height: 100vh;
overflow: hidden;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="wrapper" data-slide="1"></div>
I have a bunch of elements of the same type that have different parents, but I would like to be able to seamlessly navigate/cycle through all of them as if they were together.
<div>

I've managed to get this far: https://jsfiddle.net/pj0ecxge/
Currently it doesn't function as intended, as prev() and next() are only meant to target sibling elements, so the arrows don't work if the previous or next element is in another parent.
A single element will always be open by default, but it won't always be the same element as shown in the example. Also, only one element can be open at the same time.
If it makes a difference, I can add a single class to all children elements, but I can't change the HTML structure i.e put them all inside the same parent.
It would be nice if the navigation is infinite - i.e clicking next while the last element is open will show the first element and vice versa, but this is not required if it's too complex to do.
Thanks in advance and any help will be very appreciated!
You can check whether there are next/previous elements, if not then you can move a layer up/down like
$('.prev').click(function(e) {
e.preventDefault();
var current = $('.open');
var prev = current.prev();
if (!prev.length) {
prev = current.parent().prev('div').children('a:last-child')
}
if (prev.length) {
current.removeClass('open');
prev.addClass('open');
}
});
$('.next').click(function(e) {
e.preventDefault();
var current = $('.open');
var next = current.next();
if (!next.length) {
next = current.parent().next('div').children('a:first-child')
}
if (next.length) {
current.removeClass('open');
next.addClass('open');
}
});
* {
margin: 0;
padding: 0;
box-sizing: border-box;
text-align: center;
}
div {
font-size: 0;
}
div a {
width: 150px;
height: 150px;
border: 2px solid black;
}
a {
display: inline-block;
}
.open {
background: red;
}
.prev,
.next {
font-size: 100px;
text-decoration: none;
margin: 50px;
}

Find the next set when the current set has reached either end. And the if the set is the last one then go back to the first one (and vice-versa).
$('.prev').click(function(e) {
e.preventDefault();
var current = $('.open');
var prev = current.prev();
if (!prev.length) {
prev = current.parent().prev('div').children('a:last-of-type');
if (!prev.length) {
prev = $('div:last-of-type').children('a:last-of-type');
}
}
current.removeClass('open');
prev.addClass('open');
});
$('.next').click(function(e) {
e.preventDefault();
var current = $('.open');
var next = current.next();
if (!next.length) {
next = current.parent().next('div').children('a:first-of-type');
if (!next.length) {
next = $('div:first-of-type').children('a:first-of-type');
}
}
current.removeClass('open');
next.addClass('open');
});
