I want to build a slider with buttons and I can`t figure out how should I do it.
When I hit the right button it slides 2 pages then show a blank, and thinking the problem is on the arrowRight function.
If anyone knows why my code isn't working please explain to me.
//FOR SLIDER
let sliderImages = document.querySelectorAll(".slide"),
arrowLeft = document.querySelector("#arrow-left"),
arrowRight = document.querySelector("#arrow-right"),
current = 0;
function reset() {
for (let i = 0; i < sliderImages.length; i++) {
sliderImages[i].style.display = 'none';
}
}
function startSlide() {
reset();
sliderImages[0].style.display = 'block';
}
startSlide();
function slideLeft() {
reset();
sliderImages[current - 1].style.display = 'block';
current--
}
arrowLeft.addEventListener('click', function () {
if (current === 0) {
current = sliderImages.length;
}
slideLeft();
})
function slideRight() {
reset();
sliderImages[current + 1].style.display = 'block';
current++
}
arrowRight.addEventListener('click', function () {
if (current === sliderImages.length) {
current = 0;
}
slideRight();
})
I don't think your method is perfect for that task. Usually it's two containers - one for visible part, other is full of images. It'll look something like this:
const sliderImages = document.querySelectorAll(".slide"),
arrowLeft = document.querySelector("#arrow-left"),
arrowRight = document.querySelector("#arrow-right"),
container = document.querySelector(".container");
document.addEventListener("DOMContentLoaded", function() {
container.style.width = 100 * sliderImages.length + "%";
sliderImages.forEach((el) => {
el.style.width = 100 / sliderImages.length + "%";
})
startSlider()
});
function startSlider() {
let pos = 0;
arrowLeft.addEventListener("click", slideLeft)
arrowRight.addEventListener("click", slideRight)
function slideLeft() {
if(pos === 0) {
pos = sliderImages.length - 1;
} else{
pos--;
}
slide()
}
function slideRight() {
if(pos === sliderImages.length - 1) {
pos = 0;
} else {
pos++;
}
slide()
}
function slide() {
$(container).animate({left: -100 * pos + "%"}, 500)
}
}
*{
padding: 0;
margin: 0;
}
body{
width: 100%;
}
.outer-container {
width: 80%;
margin: 5px auto;
overflow: hidden;
position: relative;
}
.slide > img {
width: 100%;
}
.container {
display: flex;
position: relative;
}

If you just a fix for your code, here's what I've changed:
arrowRight.addEventListener('click', function () {
//Make sure that's current less than the number of images
if (current + 1 == sliderImages.length) {
current = 0;
} else {
current++;
}
slide();
})
//Moved checks and current position management from slide
//Functions to click listeners
arrowLeft.addEventListener('click', function () {
if (current === 0) {
current = sliderImages.length - 1;
} else {
current--;
}
slide();
})
//That let me merge your two function into one
//And your checks for positions was a little off
function slide(){
reset();
sliderImages[current].style.display = 'block';
}
I hope my answer helped you. If you have any questions about this code add a comment below.

can u help me to adjust my code to make infinite slider? I tried on my own but when I changed conditions I got the problem with proper working.. just want to make it go from the last slide to first when the limit of slides is reached.. this is my code in JS
var nextBtn = $('.next_btn');
var prevBtn = $('.prev_btn');
var allSlides = $('.slide');
var indexSlide = 0;
$(allSlides[indexSlide]).addClass('visible');
nextBtn.on('click', function(){
if (indexSlide >= allSlides.length - 1) {
indexSlide = allSlides.length - 1;
} else {
$(allSlides[indexSlide]).removeClass('visible');
indexSlide++;
$(allSlides[indexSlide]).addClass('visible');
}
})
prevBtn.on('click', function(){
if (indexSlide <=0) {
indexSlide = 0;
} else {
$(allSlides[indexSlide]).removeClass('visible');
indexSlide--;
$(allSlides[indexSlide]).addClass('visible');
}
})
hide slide,
increment/decrement index
check whether it's in range (otherwise set proper value)
show new slide
var nextBtn = $('.next_btn');
var prevBtn = $('.prev_btn');
var allSlides = $('.slide');
var indexSlide = 0;
var lastIndex = allSlides.length - 1;
$(allSlides[indexSlide]).addClass('visible');
nextBtn.on('click', function() {
$(allSlides[indexSlide]).removeClass('visible');
indexSlide++;
if (indexSlide > lastIndex) {
indexSlide = 0;
}
$(allSlides[indexSlide]).addClass('visible');
})
prevBtn.on('click', function() {
$(allSlides[indexSlide]).removeClass('visible');
indexSlide--;
if (indexSlide < 0) {
indexSlide = lastIndex;
}
$(allSlides[indexSlide]).addClass('visible');
})
.slide {
display: none;
}
.slide.visible {
display: block;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

<div class="slide">1</div>
<div class="slide">2</div>
<div class="slide">3</div>
I am trying to add a class to a div when another class is been removed with JS.
This is my HTML:
<body class="homepage">
<div id="wrap">
<div id="projects">
<section id="project-0" class="slide active"> Slide 1</section>
<section id="project-1" class="slide active"> Slide 2</section>
<section id="project-2" class="slide active"> Slide 3</section>
</div>
</div>
<div class="content"> Website main content </div>
This is a vertical slide, so when you scroll down, the active class is removed with JS. What I want to achieve is to add a class to body when the active is removed from project-2.
This is what I have so far, but it doesn't recognise the class active because it's been added via JS...
if(!$("#project-2").hasClass("active")){
$("body").addClass("shifted");
}
JS:
var delta = 0;
var currentSlideIndex = 0;
var scrollThreshold = 30;
var slides = $(".slide");
var numSlides = slides.length;
function elementScroll (e) {
console.log (Math.abs(delta));
// --- Scrolling up ---
if (e.originalEvent.detail < 0 || e.originalEvent.wheelDelta > 0) {
delta--;
if ( Math.abs(delta) >= scrollThreshold) {
prevSlide();
}
}
// --- Scrolling down ---
else {
delta++;
if (delta >= scrollThreshold) {
nextSlide();
}
}
// Prevent page from scrolling
return false;
}
function showSlide() {
// reset
delta = 0;
slides.each(function(i, slide) {
$(slide).toggleClass('active', (i >= currentSlideIndex));
});
}
function prevSlide() {
currentSlideIndex--;
if (currentSlideIndex < 0) {
currentSlideIndex = 0;
}
showSlide();
}
function nextSlide() {
currentSlideIndex++;
if (currentSlideIndex > numSlides) {
currentSlideIndex = numSlides;
}
showSlide();
}
$(window).on({
'DOMMouseScroll mousewheel': elementScroll
});
You can see here how it works
Thanks
By looking at your JS code I believe you want to add class to body while scrolling down. You may try below code:
function prevSlide() {
currentSlideIndex--;
if(currentSlideIndex == (numSlides-1))
{
$("body").removeClass("shifted"); // remove the class from body
}
if (currentSlideIndex < 0) {
currentSlideIndex = 0;
}
showSlide();
}
function nextSlide() {
currentSlideIndex++;
if (currentSlideIndex > numSlides) {
currentSlideIndex = numSlides;
$("body").addClass("shifted"); // add the class to body
}
showSlide();
}
Your check for the absence of the class is only started once. You had to do this with an interval from 100 ms or whatever you want:
setInterval(function()
{
if (!$("#project-2").hasClass("active")){
$("body").addClass("shifted");
}
}, 100);
I'm trying to make a count-down that counts down from 200 to 0 in steps of 10.
This timer can be stopped and should then be reset to 200, however, I need also the value of the moment is stopped. The countdown fills the div #log with innerHTML. Whenever I "stop" the timer, I take the value of #log and place it in #price and I hide #log. The problem here is that the timer continues in the background, while I want it to reset so it can be started again by clicking on start. However, it just continues counting down and only after it's done, I can start it again.
In the example, it doesn't take so long for it to reach 0, but in the end, it'll take 15-20 seconds to reach 0, which'll be too long to wait for.
So in short: Countdown 200-0, but on click of Start-button or spacebar, it should stop the function running at the moment, so it can be started again.
See this PEN
If you have any suggestions on how to approach it completely different, you're very welcome to share!

I "re-code" your code because there are several issues there.
Just read the code and tell me if that's you are looking for or if you have any questions..
var log = document.getElementById("log");
var btn = document.getElementById("btn");
var price = document.getElementById("price");
var counting = false;
var timer;
var c = 0;
function start(count) {
btn.blur();
if (!counting) {
c = count;
counting = true;
log.innerHTML = count;
timer = setInterval(tick, 1500);
tick();
};
};
function tick() {
if (c >= 0) {
log.innerHTML = c;
c -= 10;
}
else {
clearInterval(timer);
c = arguments[0];
counting = false;
btn.className = "normal";
}
}
btn.onclick = function() {
resetTimer();
var btnClassName = btn.getAttribute("class");
if (btnClassName == "normal") {
price.style.display = 'none';
log.style.display = 'block';
btn.className = "counting";
log.innerHTML = "";
start(200);
} else {
pause();
}
};
document.body.onkeyup = function(e) {
if(e.keyCode == 32) {
e.preventDefault();
pause();
}
}
function pause() {
resetTimer();
price.innerHTML = log.innerHTML;
price.style.display = 'block';
log.style.display = 'none';
btn.className = 'normal';
counting = false;
}
function resetTimer() {
clearInterval(timer);

Though you have already got your answer, you can try something like this:
Also I have taken liberty to reformat your code, and for demonstration purpose, have kept delay for interval as 1000
JSFiddle
function Counter(obj) {
var _initialVaue = obj.initialValue || 0;
var _interval = null;
var status = "Stopped";
var start = function() {
this.status = "Started";
if (!_interval) {
_interval = setInterval(obj.callback, obj.delay);
}
}
var reset = function() {
stop();
start();
}
var stop = function() {
if (_interval) {
this.status = "Stopped";
window.clearInterval(_interval);
_interval = null;
}
}
return {
start: start,
reset: reset,
stop: stop,
status: status
}
}
function init() {
var counterOption = {}
var count = 200;
counterOption.callback = function() {
if (count >= 0) {
printLog(count);
count -= 10;
} else {
counter.stop();
}
};
counterOption.delay = 1000;
counterOption.initialValue = 200
var counter = new Counter(counterOption);
function registerEvents() {
document.getElementById("btn").onclick = function() {
if (counter.status === "Stopped") {
count = counterOption.initialValue;
counter.start();
printLog("")
toggleDivs(counter.status)
}
};
document.onkeyup = function(e) {
if (e.keyCode === 32) {
printLog(counterOption.initialValue);
counter.stop();
toggleDivs(counter.status)
printPrice(count);
}
}
}
function printLog(str) {
document.getElementById("log").innerHTML = str;
}
function printPrice(str) {
document.getElementById("price").innerHTML = str;
}
function toggleDivs(status) {
document.getElementById("log").className = "";
document.getElementById("price").className = "";
var hideID = (status === "Started") ? "price" : "log";
document.getElementById(hideID).className = "hide";
}
registerEvents();
}
init();
body {
font: 100% "Helvetica Neue", sans-serif;
text-align: center;
}
.hide{
display: none;
}

I need when i click button, it shows "you look amazing" . and it will be hide after 5 seconds. here is my jsfiddle: https://jsfiddle.net/5cvsm1a2/
May i know how to do this? thanks in advance.
You can use setTimeout() like
var timer;
btn.addEventListener('click', function (e) {
clearTimeout(timer);
if (el.classList.contains('is-hidden')) {
fadeIn(el);
timer = setTimeout(function () {
fadeOut(el);
},5000)
} else {
fadeOut(el);
}
});
// fade out
function fadeOut(el) {
el.style.opacity = 1;
(function fade() {
if ((el.style.opacity -= .1) < 0) {
el.style.display = 'none';
el.classList.add('is-hidden');
} else {
requestAnimationFrame(fade);
}
})();
}
// fade in
function fadeIn(el, display) {
if (el.classList.contains('is-hidden')) {
el.classList.remove('is-hidden');
}
el.style.opacity = 0;
el.style.display = display || "block";
(function fade() {
var val = parseFloat(el.style.opacity);
if (!((val += .1) > 1)) {
el.style.opacity = val;
requestAnimationFrame(fade);
}
})();
}
var btn = document.querySelector('.js-btn');
var el = document.querySelector('.js-fade');
var timer;
btn.addEventListener('click', function(e) {
clearTimeout(timer);
if (el.classList.contains('is-hidden')) {
fadeIn(el);
timer = setTimeout(function() {
fadeOut(el);
}, 5000)
} else {
fadeOut(el);
}
});
.is-hidden {
display: none;
}
.btn {
background: #ccc;
border-radius: 3px;
display: inline-block;
padding: 5px;
}
body {
padding: 40px;
}
<span class="js-btn btn">Click me</span>
<div class='js-fade is-hidden'>You look amazing!</div>
I see that your code contains only js but as you are asking about jquery solution(which is way simplier) here u have some:
$('.js-btn').on('click', function() {
$('.js-fade').fadeIn().delay(5000).fadeOut();
});
I'm making a whack-a-mole game and this is what I have so far, I'm aware this is sloppy and probably isn't the easiest/smartest way to do this. What I need to know is how to get my animations to animate at separate times. This current code works to animate 9 different moles coming out of holes but I need them to animate at different times(so none of them will come up at the same time, or within a few milliseconds of eachother) My current code is

Generate 9 random numbers between 0 and your start time variation. Decide the max distance you want between the animations and scale the random numbers to that time frame. Then, set 9 timers to those times from now so each timer starts an animation.
If you wanted the animations to start over 500 milliseconds, you'd do something like this:
var randomTimes = [9];
for (var i = 0; i < 9; i++) {
randomTimes[i] = Math.floor(Math.random() * 501);
}
Now you have 9 random times spread out over 500 milliseconds and you can use those values with setTimeout to start each animation at a random time.
Copy/pasting a function this way is indeed sloppy!
You need to setup a flag:
var isMole = false;//at first there is no mole
if(!isMole){
//there is no mole, you can show one here
isMole = true;//there is a mole now!
}else{
//there is a mole, we wait.
}
Now set that flag to false when the mole times out or it struck by a hammer!
