I have created a horizontal projects gallery.
I want to let the visitor drag right & left to scroll.
This is my pen: https://codepen.io/omritk1/pen/qBByEoR.
My problem is that after the scroll, on "mouseup", it triggers click on the link.
How can I prevent this event but also let the user click on the link.
(I have used this pen as to set the JS: https://codepen.io/toddwebdev/pen/yExKoj)
const slider = document.querySelector('.catalog-list');
let isDown = false;
let startX;
let scrollLeft;
slider.addEventListener('mousedown', (e) => {
isDown = true;
slider.classList.add('active');
startX = e.pageX - slider.offsetLeft;
scrollLeft = slider.scrollLeft;
});
slider.addEventListener('mouseleave', () => {
isDown = false;
slider.classList.remove('active');
});
slider.addEventListener('mouseup', () => {
isDown = false;
slider.classList.remove('active');
});
slider.addEventListener('mousemove', (e) => {
if(!isDown) return;
e.preventDefault();
const x = e.pageX - slider.offsetLeft;
const walk = (x - startX) * 1;
slider.scrollLeft = scrollLeft - walk;
console.log(walk);
});

Looks like a duplicate of this .
Try the below snippet.
const slider = document.querySelector(".catalog-list");
const preventClick = (e) => {
e.preventDefault();
e.stopImmediatePropagation();
}
let isDown = false;
let isDragged = false;
let startX;
let scrollLeft;
slider.addEventListener("mousedown", e => {
isDown = true;
slider.classList.add("active");
startX = e.pageX - slider.offsetLeft;
scrollLeft = slider.scrollLeft;
});
slider.addEventListener("mouseleave", () => {
isDown = false;
slider.classList.remove("active");
});
slider.addEventListener("mouseup", (e) => {
isDown = false;
const elements = document.querySelectorAll("a");
if(isDragged){
for(let i = 0; i<elements.length; i++){
elements[i].addEventListener("click", preventClick);
}
}
else{
for(let i = 0; i<elements.length; i++){
elements[i].removeEventListener("click", preventClick);
}
}
slider.classList.remove("active");
isDragged = false;
});
slider.addEventListener("mousemove", e => {
if (!isDown) return;
isDragged = true;
e.preventDefault();
const x = e.pageX - slider.offsetLeft;
const walk = (x - startX) * 2;
slider.scrollLeft = scrollLeft - walk;
console.log(walk);
});

Add this to your CSS file
.active .catalog-item {
pointer-events: none;
}
EDIT: Credits: https://stackoverflow.com/a/24273710/5757893
EDIT: Then remove the following line from mousedown event
slider.classList.add('active');
And add it to the mousemove event method as follows:
if (Math.abs(startX - e.pageX) > 10) {
slider.classList.add('active');
}
So that if you start dragging at least 10 pixels it won't register pointer events, but if you didn't move too much, it'll stay click the link.

for some reason the close button on the sidebar is not showing nor working, the show sidebar works perfectly fine however the closing function is not working. im providing the html, css ans javascript related to the close function
here's my html:
<aside class="sidenav">
<div class="sidenav__close-icon">
<i class="bi bi-x-lg"></i>
</div>
<img class="sidenav__logo" src="../static/img/ManageX5.png">
<ul class="sidenav__list">
<li class="sidenav__list-item">
<a class="sidenav__list-item-items" href="{{url_for('dashboard')}}">Dashboard</a>
</li>
<li class="sidenav__list-item">
<a class="sidenav__list-item-items" href="{{url_for('profile')}}">Profile</a>
</li>
<li class="sidenav__list-item">
<a class="sidenav__list-item-items" href="{{url_for('users')}}">Users</a>
</li>
<li class="sidenav__list-item">
<a class="sidenav__list-item-items" href="{{url_for('projects')}}">Projects</a>
</li>
<li class="sidenav__list-item">
<a class="sidenav__list-item-items" href="{{url_for('sites')}}">Sites</a>
</li>
</ul>
<ul class="sidenav__logout">
<li class="list-logout-item">
<a class="sidenav__list-item-logout" href="#">logout</a>
</li>
</ul>
</aside>
this is the JS part:
const menuIconEl = $('.menu-icon');
const sidenavEl = $('.sidenav');
const sidenavCloseEl = $('.sidenav__close-icon');
/*===== Add and remove provided class names =====*/
function toggleClassName(el, className) {
if (el.hasClass(className)) {
el.removeClass(className);
} else {
el.addClass(className);
}
}
/*===== Open the side nav on click =====*/
menuIconEl.on('click', function() {
toggleClassName(sidenavEl, 'active');
});
/*===== Close the side nav on click =====*/
sidenavCloseEl.on('click', function() {
toggleClassName(sidenavEl, 'active');
});
and this is the css related to the sidebar:
.sidenav__close-icon {
position: absolute;
visibility: visible;
top: 8px;
right: 12px;
cursor: pointer;
font-size: 20px;
color: #000;
}
The reason of why you can't see the close icon isn't showing up is that you don't have the necessary styles that makes the element (.sidenav__close-icon) to be rendered/shown as an icon.
If you have it somewhere in your project, I suggest you making some tweaks like the following:
You can use jQuery's toggleClass method to toggle a class
function toggleClassName(el, className) {
el.toggleClass(className);
}
The close button/icon has CSS properties (position, top, right) that makes it positioned to top right of the page which results in not visible. You may have to add the following CSS in order to give close icon a relative position. In your case, the relativity can be inherited from its parent, the .sidenav element.
.sidenav {
position: relative;
width: 200px;
}
.sidenav__close-icon {
position: absolute;
visibility: visible;
top: 8px;
right: 12px;
cursor: pointer;
font-size: 20px;
color: #000;
}
Here's a snippet which toggles active class and demonstrates the change
const menuIconEl = $('.menu-icon');
const sidenavEl = $('.sidenav');
const sidenavCloseEl = $('.sidenav__close-icon');
/*===== Add and remove provided class names =====*/
function toggleClassName(el, className) {
el.toggleClass(className);
// Much shorter, but the following lines can also work
/*if (el.hasClass(className)) {
el.removeClass(className);
} else {
el.addClass(className);
}*/
}
/*===== Open the side nav on click =====*/
menuIconEl.on('click', function () {
toggleClassName(sidenavEl, 'active');
});
/*===== Close the side nav on click =====*/
sidenavCloseEl.on('click', function () {
toggleClassName(sidenavEl, 'active');
});
.sidenav {
position: relative;
width: 200px;
}
.sidenav__close-icon {
position: absolute;
visibility: visible;
top: 8px;
right: 12px;
cursor: pointer;
font-size: 20px;
color: #000;
}
.active {
outline: 1px solid red;

What I am looking to achieve is to make the items in the list continue scrolling even at the last item in both directions. i.e: Let it continue to scroll starting from the first OR last item all over again. I have worked out the HTML and CSS but don't know what method to use in js/jquery. I'd really appreciate any help or a good pointer.
Here is the HTML
<html>
<div class="container">
<ul class="horscroll" id="autoscrollR">
<li>
<a href="#myGallery" data-slide-to="0" data-tooltip="acci"><img
class="img-thumbnail"
src="http://dummyimage.com/96x96/f0f0f0/626262.png&text=1" >
</a>
</li>
<li>
<a href="#myGallery2" data-slide-to="1" data-tooltip="aiico"><img
class="img-thumbnail"
src="http://dummyimage.com/96x96/f0f0f0/626262.png&text=2">
</a>
</li>
<li>
<a href="#myGallery3" data-slide-to="2" data-tooltip="asaba"><img
class="img-thumbnail"
src="http://dummyimage.com/96x96/f0f0f0/626262.png&text=3">
</a>
</li>
...........
</ul>
</div> </html>
And the CSS is used is very basic for an example:
.container{
max-width: 100%;
}
.horscroll {
display: -webkit-inline-box;
width: 100%;
overflow: auto;
margin:10px;
}
ul {
padding: 0;
margin: 0;
list-style: none;
}
li {
display: list-item;
text-align: -webkit-match-parent;
}
.img-thumbnail {
margin: 5px 5px 0px 5px;
border: 1px solid #;
border-radius: 4px;
}
Now the Js function to use is where I am stuck.
Here is the FIDDLE LINK
So you are looking for something like this:-
var bgWidth = 350; //Max-width of <li> you would like to set.
var scrollPos = Math.ceil($('body').width() / 20);
$(document).ready(function() {
$('body').width(bgWidth + $(window).width());
$(window).scroll(function() {
if ($(window).scrollLeft() >= ($('body').width() - $(window).width())) {
$(window).scrollLeft(1 + scrollPos / 4);
} else if ($(window).scrollLeft() == 0) {
$(window).scrollLeft($('body').width() - $(window).width() - scrollPos / 4);
}
});
});
$(window).resize(function() {
$('body').width(bgWidth + $(window).width());
});
.container {
max-width: 100%;
}
.horscroll {
display: -webkit-inline-box;
width: 100%;
overflow: auto;
margin: 10px;
}
ul {
padding: 0;
margin: 0;
list-style: none;
}
li {
display: list-item;
text-align: -webkit-match-parent;
}
.img-thumbnail {
margin: 5px 5px 0px 5px;
border: 1px solid #;
border-radius: 4px;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="container">
<ul class="horscroll" id="autoscrollR">
<li>
<a href="#myGallery" data-slide-to="0" data-tooltip="acci"><img class="img-thumbnail" src="http://dummyimage.com/96x96/f0f0f0/626262.png&text=1">
</a>
</li>
<li>
<a href="#myGallery2" data-slide-to="1" data-tooltip="aiico"><img class="img-thumbnail" src="http://dummyimage.com/96x96/f0f0f0/626262.png&text=2">

Hope this helps you!
i have a typical carousel when i click left button if marginLeft is 0 it doesn't slide but i don't know what limited value to set for the slider when i click right button.
i tried calculating the images width and the margin space between them to set the limit value for the right button so slider doesn't slide past it but that doesn't work if you see it on another device because it's width is higher.
codepen : https://codepen.io/anon/pen/bXBaYW?editors=1010
// caoursel
const carousel = document.getElementById('carousel');
const leftArrow = carousel.querySelector('.carousel-left-arrow');
const rightArrow = carousel.querySelector('.carousel-right-arrow');
const slides = carousel.querySelector('.slides');
const slideImgs = carousel.querySelectorAll('.slide img');
let marginLeft = 0;
// works fine
function scrollLeft() {
if (getComputedStyle(slides).marginLeft >= '0px') return;
marginLeft += 310;
slides.style.marginLeft = marginLeft + "px";
}
// need to set right slide a limited value.
function scrollRight() {
if (getComputedStyle(slides).marginLeft <= '-1240px') return; // dont scroll past this value
marginLeft -= 310;
slides.style.marginLeft = marginLeft + "px";
}
leftArrow.addEventListener('click', scrollLeft);
rightArrow.addEventListener('click', scrollRight);
i want the slider to stop sliding when i reach the last image.
What you need to do is to not hardcode the width of the .slides container in CSS and JS.
Thus allowing you to dynamically compute the width of the .slides container, and the remaining space you can scroll/slide.
Below is an illustration of the variable and their values in relation to the whole component.
remainingSpaceToScroll will tell you how much space you have on the right, so you can not exceed the limit. The value of it can be found with simple math, by subtracting the sum of parentWidth and currentScroll from the value in scrollWidth.
Here is the code from your example updated so you can inspect.
I've removed the space between the slides for the simplicity sake.
https://codepen.io/anon/pen/BXpaNv
const carousel = document.getElementById("carousel");
const leftArrow = carousel.querySelector(".carousel-left-arrow");
const rightArrow = carousel.querySelector(".carousel-right-arrow");
const slides = carousel.querySelector(".slides");
const slideImgs = carousel.querySelectorAll(".slide img");
let marginLeft = 0;
let carouselImageWidth = 300;
function scrollLeft() {
let parentWidth = carousel.offsetWidth;
let scrollWidth = parseInt(getComputedStyle(slides).width, 10);
let currentScroll = Math.abs(
parseInt(getComputedStyle(slides).marginLeft, 10)
);
let remainingSpaceToScroll = currentScroll;
if (remainingSpaceToScroll <= 0) {
return;
} else if (remainingSpaceToScroll >= carouselImageWidth) {
marginLeft = -(currentScroll - carouselImageWidth);
} else {
marginLeft = -(currentScroll - remainingSpaceToScroll);
}
slides.style.marginLeft = marginLeft + "px";
}
function scrollRight() {
let parentWidth = carousel.offsetWidth;
let scrollWidth = parseInt(getComputedStyle(slides).width, 10);
let currentScroll = Math.abs(
parseInt(getComputedStyle(slides).marginLeft, 10)
);
let remainingSpaceToScroll = scrollWidth - (parentWidth + currentScroll);
if (remainingSpaceToScroll <= 0) {
return;
} else if (remainingSpaceToScroll >= carouselImageWidth) {
marginLeft = -(currentScroll + carouselImageWidth);
} else {
marginLeft = -(currentScroll + remainingSpaceToScroll);
}
slides.style.marginLeft = marginLeft + "px";
}
leftArrow.addEventListener("click", scrollLeft);
rightArrow.addEventListener("click", scrollRight);

I have created a very raw, pure CSS solution, as good starting point for you. Using different animations and delays you could achieve some really awesome effects.
body {
margin: 0;
padding: 0;
}
.route {
height: 100vh;
position: relative;
color: #fff;
}
.navbar {
position: fixed;
}
.slide {
position: relative;
height: 100%;
width: 33.33%;
margin: 0;
float: left;
}
.slide-1 {
background-image: url(https://picsum.photos/1200/800?image=11);
}
.slide-2 {
background-image: url(https://picsum.photos/1200/800?image=12);
}
.slide-3 {
background-image: url(https://picsum.photos/1200/800?image=13);
}
.slideshow {
position: absolute;
top: 0;
bottom: 0;
right: 0;
left: 0;
z-index: 0;
overflow: hidden;
color: #000;
}
.slideshow-inner {
position: relative;
height: 100%;
width: 300%;
animation: move 20s ease infinite;
}
.intro .intro-content {
text-align: center;
position: absolute;
}
#keyframes move {
0% {
transform: translate(0, 0);
}
33.33% {
transform: translate(-33.33%, 0);
}
66.66% {
transform: translate(-66.66%, 0);
}
}

Presumably you mean a time-based slideshow rather than one where the user presses buttons. The various options are all typically handled with JavaScript. As your background element has children, I would extend your existing code by adding new classes corresponding to new background images, and switching between them.
.bg1 {
background-image: url(asset-path("img1.png"));
}
.bg2 {
background-image: url(asset-path("img2.png"));
}
.bg3 {
background-image: url(asset-path("img3.png"));
}
Then add the first class to your background element:
<div id="home" class="intro route bg-image bg1" >
and include JS code to cycle through the classes, like below - included as part of a snippet so you can see the effect.
function updateSlide() {
const bgCount = 3; //This needs to match the number of background classes - main weakness of this snippet
const bgElem = document.getElementById('home'); // Background element
let foundClasses = []; //List of background classes found
let bgIndex = 0;
for(let classIndex = 0; classIndex < bgElem.classList.length; classIndex++) { // Using a full for in case the element somehow gets multiple background classes
const thisClass = bgElem.classList.item(classIndex);
if(thisClass.substr(0, 2) == 'bg') {
foundClasses += thisClass;
bgIndex = parseInt(thisClass.substr(2)) + 1;
}
}
if(bgIndex > bgCount) {
bgIndex = 1;
}
bgElem.classList.add('bg' + bgIndex); //Apply the new class
bgElem.classList.remove(foundClasses); //Remove all previous background classes
}
setInterval(updateSlide, 2000); // Change every 2 seconds
#home {
display: block;
}
.bg1 {
background: red;
}
.bg2 {
background: yellow;
}
.bg3 {
background: green;
}
<div id="home" class="bg1">Test</div>
Long-term, you would want the cycling script to get its background-count from a Rails variable or the HTML instead of a hard-coded value.
Kindly help me with my problem, my scroll effects are not working. I am not able to identify the problem. I am using bootstrap 4. Here's my code.
//SCROLL EFFECT
$(".nav-link").click(function () {
var href = $(this).attr('href');
scrollAmount = 0;
if (href == "#home")
scrollAmount = 0;
else
scrollAmount = $(href).offset().top - 65;
$('html, body').animate({
scrollTop: scrollAmount
}, 1000);
});

Try with data();
$(document).ready(function(){
var countTimer = 1000;
$('a').on('click', function(event){
//event.preventDefault();
var currentID = $(this).attr('id');
//console.log(currentID);
var destination = $(this).data('anchor');
//console.log(destination);
var p = $('#' + destination);
var position = p.position();
$('body,html').animate({
scrollTop:position.top
}, countTimer);
});
})
