Comma between numbers script

I have tried endless solutions that I have found for this on these forums and none that I have found work or I am simply putting it in the wrong place. I am trying to force commas for thousand and millions places. Any suggestions and placement would be appreciated.
Thank you.
jQuery(window).scroll(startCounter);
function startCounter() {
var hT = jQuery('.counter').offset().top,
hH = jQuery('.counter').outerHeight(),
wH = jQuery(window).height();
if (jQuery(window).scrollTop() > hT+hH-wH) {
jQuery(window).off("scroll", startCounter);
jQuery('.counter').each(function () {
var $this = jQuery(this);
jQuery({ Counter: 0 }).animate({ Counter: $this.text() }, {
duration: 4000,
easing: 'swing',
step: function () {
$this.text(Math.ceil(this.Counter));
}
});
});
}
}

Assuming you would want to comma seperate values by hunders,thousands,millions,...
You may do:
let num = 9876543210;
console.log(num.toString().replace(/\B(?=(\d{3})+(?!\d))/g, ","));
// or
console.log((num).toLocaleString());
// or
console.log(new Intl.NumberFormat('en-US', {}).format(num));

Jquery - How to loop this slider?

So I've been working on a slider and I don't really know how to make it repeat itself. So far I've only listed 10 slides but in the end I'll have around 20.
Here's a link to a JS fiddle so you can see what I've got so far:
https://jsfiddle.net/sth23e2w/
$(document).ready(function() {
//settings for slider
var width = 360;
var animationSpeed = 1000;
var pause = 3000;
var currentSlide = 1;
//cache DOM elements
var $slider = $(".characters");
var $slideContainer = $(".slide-characters", $slider);
var $slides = $(".char-avatar", $slider);
$(".right-slide").click(function() {
$slideContainer.animate(
{ "margin-left": "+=" + width },
animationSpeed,
function() {
if (++currentSlide === $slides.length) {
currentSlide = 1;
$slideContainer.css("margin-left", 0);
}
}
);
});
$(".left-slide").click(function() {
$slideContainer.animate(
{ "margin-left": "-=" + width },
animationSpeed,
function() {
if (++currentSlide === $slides.length) {
currentSlide = 1;
$slideContainer.css("margin-left", 0);
}
}
);
});
});
Or if you really want you could check out the live version I've got over at Codepen: https://codepen.io/Crownedpride/project/editor/ZmbqRv/
If you want to know what it's going to be used for:
I'm currently writing a fantasy novel which I've got an artist drawing characters for. I want to display those characters on my own website via that setup I've made. There's roughly going to be 20 different characters that he'going to draw for me, although later there might be more depending if there'll be a Volume 2.
I'm looking forward to your replies.
ps: I'm really new to Jquery/js so please go easy on me >_<

$.each animation running separately

I'm trying to run each animation function one after the other instead of all at once.
This is what I've got so far:
$(document).ready(function(){
var bars = $('.bar');
bars.each(function(){
var widthpercent = $(this).attr("data-percent");
$(this).fadeIn();
$(this).animate({width:widthpercent},500);
});
});
I've tried using .delay() and setTimeout() in various combinations to no avail.
Could anyone point me in the right direction? Thank you!

It sounds to me like you're looking for animate's complete function. You can write a recursive function to keep calling the function in the complete function until all the items have been animated. To simplify: every time one element is animated, a callback is fired that animates the next element. That is the purpose of the complete parameter, so I'm certain that is what you're looking for.
Here's an example you can adapt to your specific needs.
Live demo here (click).
var $divs = $('div');
function animate(element) {
$(element).animate({height: '30px'}, {
complete: function() {
if (current < $divs.length-1) {
++current;
animate($divs[current]);
}
}
});
}
var current = 0;
animate($divs[current]);
Further, this same logic can be applied to your fadeIn. Just wrap fadeIn's callback around that logic, like this:
Live demo here (click).
var $divs = $('div');
function animate(element) {
$(element).fadeIn(function() { //now the animation is a callback to the fadeIn
$(element).animate({height: '70px'}, {
complete: function() {
if (current < $divs.length-1) {
++current;
animate($divs[current]);
}
}
});
});
}
var current = 0;
animate($divs[current]);
And here's your code: live demo here (click).
$(document).ready(function(){
var $divs = $('.bar');
function animate(element) {
$(element).fadeIn(function() { //you could unwrap this depending on what you're looking for
var widthpercent = $(element).attr("data-percent");
$(element).animate({
width:widthpercent,
duration: '500ms'
}, {
complete: function() {
if (current < $divs.length-1) {
++current;
animate($divs[current]);
}
}
});
}); //end fadeIn callback
}
var current = 0;
animate($divs[current]);
});

Try this:
var animate = function (el) {
return function () {
var widthpercent = el.data('percent');
el.fadeIn();
el.animate({
width: widthpercent
}, 500);
}
}
var bars = $('.bar');
bars.each(function (index) {
var $this = $(this);
setTimeout(animate($this), index * 500);
});
Fiddle

$(document).ready(function(){
var bars = $('.bar');
bars.each(function(i){
var widthpercent = $(this).attr("data-percent");
$(this).delay(i*800).animate({width:widthpercent,opacity:1,},500);
});
});
This will animate after delaying 800 * i milliseconds.
See this JSFiddle example.

How do I call this function that's within a jquery plugin?

I'm using a jquery plugin on my page, vTicker, "for easy and simple vertical news automatic scrolling". I'm using it in combination with an rss jquery plugin. It's working fine, but I need to create a button that will do a manual scroll. Can anyone tell me how to do this? I'm guessing I need to call the moveUp function from the vTicker file, but because of the way the function is created, as well as how the vticker itself is created, I'm not really sure how to do it.
I create my vTicker like this:
$('#ticker1').rssfeed(uRL).ajaxStop(function() {
$('#ticker1 div.rssBody').vTicker();
})
And here is the vTicker code:
/*
* Tadas Juozapaitis ( kasp3rito#gmail.com )
*/
(function($){
$.fn.vTicker = function(options) {
var defaults = {
speed: 700,
pause: 15000,
showItems: 3,
animation: '',
mousePause: true,
isPaused: false
};
var options = $.extend(defaults, options);
moveUp = function(obj2, height){
if(options.isPaused)
return;
var obj = obj2.children('ul');
var iframe = $('#iFrame2');
first = obj.children('li:first').clone(true);
second = obj.children('li:odd:first').clone(true);
iframe.attr('src', (second.children('h4').children('a').attr("href")));
obj.animate({top: '-=' + height + 'px'}, options.speed, function() {
$(this).children('li:first').remove();
$(this).css('top', '0px');
});
if(options.animation == 'fade')
{
obj.children('li:first').fadeOut(options.speed);
obj.children('li:last').hide().fadeIn(options.speed);
}
first.appendTo(obj);
};
return this.each(function() {
var obj = $(this);
var maxHeight = 0;
obj.css({overflow: 'hidden', position: 'relative'})
.children('ul').css({position: 'absolute', margin: 0, padding: 0})
.children('li').css({margin: 0, padding: 0});
obj.children('ul').children('li').each(function(){
if($(this).height() > maxHeight)
{
maxHeight = $(this).height();
}
});
obj.children('ul').children('li').each(function(){
$(this).height(maxHeight);
});
obj.height(maxHeight * options.showItems);
var interval = setInterval(function(){ moveUp(obj, maxHeight); }, options.pause);
if(options.mousePause)
{
obj.bind("mouseenter",function(){
options.isPaused = true;
}).bind("mouseleave",function(){
options.isPaused = false;
});
}
});
};
})(jQuery);
Thanks for reading.

The short answer is, you can't. The moveUp function is totally isolated within the scope of the plugin, and you cannot call it directly.
To modify the plugin so that you can manually scroll, add this just before the line return this.each(function() {:
$.fn.extend({
vTickerMoveUp: function() {
var obj = $(this);
var maxHeight = 0;
obj.children('ul').children('li').each(function(){
if($(this).height() > maxHeight) maxHeight = $(this).height();
});
moveUp(obj, maxHeight);
}
});
Then, to scroll, do this:
var ticker = $('#ticker1 div.rssBody').vTicker();
ticker.vTickerMoveUp();

Since the moveup declaration is missing a var that means moveup() would be statically defined as a property of window (ie, global) once vTicker has been called. And thus I would think you could call moveup() from anywhere after that.

jQuery: The 'body' element is activating the scroll event twice

I've implemented an animation for my photo blog. I still have big problem because the 'body' element is activating the animation twice.
I think the problem stems from the $('body').animate. Because I think that when the body is animating, the scroll event would be activated again and thus triggering the event twice.
The problem of my code is scrolling the page up. When I scroll the page upwards. The scrollAnimatePrev will trigger and then $('body') element will animate itself. After the animation the animating variable is set to false. But the $('body') element triggers the scroll event because I guess when I set the scrollTop the scroll event is triggered. So once again currentPos is set to the $(window).scrollTop() then currentPos > previousPos returns true and !animating returns true so it will trigger the scrollAnimate.
Now I want to fix this. How?
$(function() {
var record = 0;
var imgHeight = $(".images").height();
var offset = $(".images").eq(0).offset();
var offsetHeight = offset.top;
var previousPos = $(window).scrollTop();
var animating = false;
var state = 0;
$(window).scroll(function() {
var currentPos = $(window).scrollTop();
console.log(currentPos);
if(currentPos > previousPos && !animating) {
record++;
scrollAnimate(record, imgHeight, offsetHeight);
animating = true;
} else if (currentPos < previousPos && !animating) {
record--
scrollAnimatePrev(record, imgHeight, offsetHeight);
animating = true;
}
previousPos = currentPos;
console.log(previousPos)
})
function scrollAnimate(record, imgHeight, offsetHeight) {
$('body').animate(
{scrollTop: (parseInt(offsetHeight) * (record+1)) + (parseInt(imgHeight) * record)},
1000,
"easeInOutQuart"
)
.animate(
{scrollTop: (parseInt(offsetHeight) * (record)) + (parseInt(imgHeight) * (record))},
1000,
"easeOutBounce",
function() {
animating = false;
}
)
}
function scrollAnimatePrev(record, imgHeight, offsetHeight) {
$('body').animate(
{scrollTop: ((parseInt(imgHeight) * record) + (parseInt(offsetHeight) * record)) - offsetHeight},
1000,
"easeInOutQuart"
)
.animate(
{scrollTop: ((parseInt(imgHeight) * record) + (parseInt(offsetHeight) * record))},
1000,
"easeOutBounce",
function() {
animating = false;
}
)
}
})

I think it might be firing that callback twice. I had a similar problem recently.
I had something similiar to
$('#id, #id2').animate({width: '200px'}, 100, function() { doSomethingOnceOnly(); })
It was calling my doSomethingOnceOnly() twice, and I thought it must have been the dual selectors in the $ argument. I simply made it 2 different selectors and it worked fine. So like this
$('#id').animate({width: '200px'}, 100);
$('#id2').animate({width: '200px'}, 100, function() { doSomethingOnceOnly(); );

Using a flag to control the trigger did the trick for me.
var targetOffset = 0;
var allow_trigger = true;
$('html,body').animate({scrollTop: targetOffset}, 'slow', function() {
if (allow_trigger) {
allow_trigger = false;
doSomethingOnlyOnce();
}
});
