How to achieve the same function of position:sticky using jQuery or JavaScript?

I'm having a hard time figuring out why the code below doesn't work as expected.
What I'm trying to achieve is same functionality with position:sticky whereas when the scrolled reaches the top of the #second-header then fixes its position below the #header which is also fixed, however, the height of the #header is unknown which is I believe can be calculated using the function outerHeight(true) on JQuery.
Then after reaching out to the bottom of the #second-header-container, remove the fixed position of #second-header turning it back to normal position.
Due to browser compatibility issues and other customization, I cannot simply use the position:sticky of css.
It looks like my logic is wrong, and I need help.
jQuery(document).ready(function(){
var $document = jQuery(document);
var header = jQuery('#header');
var second_header = jQuery('#second-header-container').find('#second-header');
var second_header_container = jQuery('#second-header-container');
var second_header_offset = second_header.offset().top;
var second_header_container_offset = second_header_container.offset().top;
jQuery(window).scroll(function(){
var top_margin = header.outerHeight(true);
var second_header_height = second_header.outerHeight(true);
var second_header_container_height = second_header_container.outerHeight(true);
if( jQuery(window).scrollTop() > (second_header_offset - second_header_height) && jQuery(window).scrollTop() < second_header_container_height) {
second_header.addClass('fixer');
second_header.css({position:'fixed', top:top_margin, 'z-index':'999999'});
} else {
second_header.removeClass('fixer');
second_header.css({position:'relative', top:'0px', 'z-index':'0'});
}
});
});

<div id="second-header">SECOND-HEADER</div>

To achieve this you need first check if the scroll height is near the second div header and within the height of the second div. Then add a class that make it stick below the main header. I have created a sticky class and added it while scrolling conditions are met.
Please check below code
jQuery(document).ready(function() {
var headerHeight = $('#header').outerHeight(true);
var secondHeaderContainer = $('#second-header-container');
const secondHeaderTopPos = secondHeaderContainer.offset().top;
const secondHeaderContainerHeight = $(secondHeaderContainer).height();
$(window).scroll(function() {
const scrollTop = $(this).scrollTop();
const secondContainerHeightEnd = secondHeaderContainerHeight + secondHeaderTopPos - $('#second-header').height() - headerHeight;
if (((secondHeaderTopPos - headerHeight) <= scrollTop) && (secondContainerHeightEnd >= scrollTop)) {
$('#second-header').addClass('sticky').css('top', headerHeight);
} else {
$('#second-header').removeClass('sticky');
}
});
});

Text Center on Progress Bar

I am trying to place the percentage total in the center of the colored progress bar but am struggling to do so.
I have tried placing the <p> tag within the different <div> tags but can't quite work it out.
Can anyone help?
// on page load...
moveProgressBar();
// on browser resize...
$(window).resize(function() {
moveProgressBar();
});
// SIGNATURE PROGRESS
function moveProgressBar() {
console.log("moveProgressBar");
var getPercent = ($('.progress-wrap').data('progress-percent') / 100);
var getProgressWrapWidth = $('.progress-wrap').width();
var progressTotal = getPercent * getProgressWrapWidth;
var animationLength = 1000;
// on page load, animate percentage bar to data percentage length
// .stop() used to prevent animation queueing
$('.progress-bar').stop().animate({
left: progressTotal
}, animationLength);
}
.progress-size {
width: 100%;
height: 50px;
}
.progress-wrap {
border: 1px solid #FFFFFF;
background: #3498DB;
height: 50px;
margin: 0px 0;
overflow: hidden;
position: relative;
}
.progress-bar {
background: #ddd;
left: 0;
position: absolute;
top: 0;
}
.progress-value {
vertical-align: middle;
line-height: 50px;
padding-left: 20px;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="progress-wrap" data-progress-percent="25">
<div class="progress-bar progress-size"></div>
</div>
<p class="progress-value progress-size alt text-center">25%</p>

You can just position the text absolutely inside the bar and then set the right to 100 minus the percentage:
// on page load...
moveProgressBar();
// on browser resize...
$(window).resize(function() {
moveProgressBar();
});
// SIGNATURE PROGRESS
function moveProgressBar() {
console.log("moveProgressBar");
var getPercent = ($('.progress-wrap').data('progress-percent') / 100);
var getProgressWrapWidth = $('.progress-wrap').width();
var progressTotal = getPercent * getProgressWrapWidth;
var animationLength = 1000;
// on page load, animate percentage bar to data percentage length
// .stop() used to prevent animation queueing
$('.progress-bar').stop().animate({
left: progressTotal
}, animationLength);
$('.progress-value').stop().animate({
right: 100 - $('.progress-wrap').data('progress-percent') + '%'
}, animationLength);
}
.progress-size {
width: 100%;
height: 50px;
}
.progress-wrap {
border: 1px solid #FFFFFF;
background: #3498DB;
height: 50px;
margin: 0px 0;
overflow: hidden;
position: relative;
}
.progress-bar {
background: #ddd;
left: 0;
position: absolute;
top: 0;
}
.progress-value {
line-height: 50px;
position: absolute;
top: 0;
bottom: 0;
left: 0;
right: 100%;
text-align:center;
margin:0;
overflow:hidden;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="progress-wrap" data-progress-percent="25">
<div class="progress-bar progress-size"></div>
<p class="progress-value alt text-center">25%</p>
</div>

You don't need positioning here. Simply put your .progress-value element into the wrapper and use the padding-left attribute to animate the percentage value as well. To center the value, you can i.e. use an offset and half of your total progress value: (progressTotal-15)/2
Here is the working example:
// on page load...
moveProgressBar();
// on browser resize...
$(window).resize(function() {
moveProgressBar();
});
// SIGNATURE PROGRESS
function moveProgressBar() {
console.log("moveProgressBar");
var getPercent = ($('.progress-wrap').data('progress-percent') / 100);
var getProgressWrapWidth = $('.progress-wrap').width();
var progressTotal = getPercent * getProgressWrapWidth;
var animationLength = 1000;
// on page load, animate percentage bar to data percentage length
// .stop() used to prevent animation queueing
$('.progress-bar').stop().animate({
left: progressTotal
}, animationLength);
$('.progress-value').stop().animate({
paddingLeft: (progressTotal-15)/2
}, animationLength);
}
.progress-size {
width: 100%;
height: 50px;
}
.progress-wrap {
border: 1px solid #FFFFFF;
background: #3498DB;
height: 50px;
margin: 0px 0;
overflow: hidden;
position: relative;
}
.progress-bar {
background: #ddd;
left: 0;
position: absolute;
top: 0;
}
.progress-value {
padding-left: 10px;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="progress-wrap" data-progress-percent="25">
<div class="progress-bar progress-size"></div>
<p class="progress-value progress-size alt text-center">25%</p>
</div>

I am not able to add and remove the classes

My Code:
window.addEventListener('scroll', scrollWhere);
function scrollWhere(e) {
var windowScroll = $(window).scrollTop();
var idScroll = $('.me').offset().top;
var height = $("#half-who").height();
if (windowScroll > idScroll) {
$('.me').addClass('me-fixed');
} else {
$('.me').removeClass('me-fixed');
}
}
I want to add a class when the scroll is past a certain point and remove it when is smaller than that certain point.

Get your idScroll value outside scrollWhere function as because it re-initiate calculation again and again and returns different values each time as because it has a fixed position. check below snippet for reference.
window.addEventListener('scroll', scrollWhere);
var idScroll = $('.me').offset().top;
function scrollWhere(e) {
var windowScroll = $(window).scrollTop();
//var height = $("#half-who").height();
if (windowScroll > idScroll) {
$('.me').addClass('me-fixed');
} else {
$('.me').removeClass('me-fixed');
}
}
.container {
height: 300vh;
width: 100%;
background-color: grey;
padding: 0;
margin: 0;
}
.content {
height: 100px;
width: 100%;
background-color: cyan;
}
.me {
height: 50px;
width: 100%;
background-color: red;
}
.me-fixed {
position: fixed;
top: 0;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="container">
<div class="content"></div>
<div class="me"></div>
</div>

Here's a simple example to add a class when scroll passing a certain point. Hope you can get an idea. >>> JSFiddle
$(window).scroll(function(){
var winH = $(window).scrollTop();
var ruler = $('.ruler').position().top;
if(ruler < winH){
$('.nav').addClass('me-fixed');
}
else{
$('.nav').removeClass('me-fixed');
}
});
body{
height: 1500px;
}
.nav{
height: 50px;
background: #a1bfbe;
color: #000;
width: 100%;
position: relative;
top: 250px;
text-align: center;
}
.nav.me-fixed{
background: #c2debf;
}
p{
font-size: 20px;
display: none;
}
.me-fixed p{
display: block;
}
.ruler{
position: fixed;
top: 150px;
border-bottom: 1px solid red;
width: 100%;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="nav">
<p>
Fixed
</p>
</div>
<div class="ruler">
</div>
Also if you can provide the html and css structure, it will be easy to identify the issue.

Multiple Window Events - Jquery

I'm trying to write a function that watches the window for a few things:
If the window is greater-than 900px and the window is scrolled passed 100 add a BG color to the nav
If the nav is scrolled passed 100 and the window is resized to less-than 900px change the BG color nav.
I've written two functions that should be doing the trick. My problem is my functions work right up until you scroll passed 100 and resize the screen: they won't apply the second class with the second bg color.
Snippet below. Can anyone provide assistance?
$(document).ready(function() {
$(window).scroll(function() {
var scroll = $(window).scrollTop();
var nav = $('nav');
if( scroll > 100 ) {
nav.addClass('scrolled');
} else {
nav.removeClass('scrolled');
}
});
$(window).resize(function() {
var mq = window.matchMedia('(min-width: 100px) and (max-width: 900px)');
if( mq.matches && $('nav').hasClass('scrolled')) {
$('nav').removeClass('scrolled');
console.log("Working");
$('nav').addClass('scrolledTwo');
} else {
console.log("Not working");
$('nav').removeClass('scrolledTwo');
}
});
});
* {
padding: 0;
margin: 0;
}
nav {
height: 70px;
width: 100%;
border: 1px solid;
transition: all .2s ease;
background-color: transparent;
position: fixed;
top: 0;
left: 0;
z-index: 1000;
}
.nav-fixedWidth {
height: inherit;
width: 1000px;
margin: 0 auto;
border: 1px solid #ccc;
}
main {
width: 100%;
height: 2000px;
border: 1px solid;
background-color: #f1f1f1;
}
.scrolled {
background-color: red;
}
.scrolledTwo {
background-color: blue;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<nav>
<div class="nav-fixedWidth"></div>
</nav>
<main></main>

Your code is working fine it is even applying the second class with the second bg color if you will resize slowly your window. The only issue is this if( mq.matches && $('nav').hasClass('scrolled')) condition. As you have mentioned $('nav').hasClass('scrolled') so first time when you will resize it will be true and then
$('nav').removeClass('scrolled');
console.log("Working");
$('nav').addClass('scrolledTwo');
this will apply scrolledTwo class to nav. After that when you will further resize it will never pass this if( mq.matches && $('nav').hasClass('scrolled')) condition, until you don't resize the screen width to less than 100px or greater than 900px and scroll, and will always goto else and you will always see the red color. Try removing it
$(document).ready(function() {
$(window).scroll(function() {
var scroll = $(window).scrollTop();
var nav = $('nav');
if( scroll > 100 ) {
nav.addClass('scrolled');
} else {
nav.removeClass('scrolled');
}
});
$(window).resize(function() {
var mq = window.matchMedia('(min-width: 100px) and (max-width: 900px)');
if( mq.matches ) {
$('nav').removeClass('scrolled');
console.log("Working");
$('nav').addClass('scrolledTwo');
} else {
console.log("Not working");
$('nav').removeClass('scrolledTwo');
}
});
});
* {
padding: 0;
margin: 0;
}
nav {
height: 70px;
width: 100%;
border: 1px solid;
transition: all .2s ease;
background-color: transparent;
position: fixed;
top: 0;
left: 0;
z-index: 1000;
}
.nav-fixedWidth {
height: inherit;
width: 1000px;
margin: 0 auto;
border: 1px solid #ccc;
}
main {
width: 100%;
height: 2000px;
border: 1px solid;
background-color: #f1f1f1;
}
.scrolled {
background-color: red;
}
.scrolledTwo {
background-color: blue;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<nav>
<div class="nav-fixedWidth"></div>
</nav>
<main></main>
Another issue in your code is if I scroll and resize the screen width between 100 to 900 and then again resize it to out of this window then there is no class assigned to your div and that is due to no class added in else of resize function. Changing that to this will do that trick also :)
else {
console.log("Not working");
$('nav').removeClass('scrolledTwo');
var scroll = $(window).scrollTop();
if( scroll > 100 ) {
$('nav').addClass('scrolled');
}
}

lightbox with 2 different progress bar inside

I have created a lightbox in javascript and I have placed inside it a progress bar that I have also created it in javascript. My problem is that when I was trying to insert a second progress bar inside my lightbox only the first works. Any idea how to fix this?
this is my jsfiddle :http://jsfiddle.net/QHMKk/3/
and my code is this:
my javascript is:
function show() {
document.getElementById('light').style.display='block';
document.getElementById('fade').style.display='block';
}
function start() {
var stepSize = 50;
setTimeout((function() {
var filler = document.getElementById("filler"),
percentage = 0;
return function progress() {
filler.style.height = percentage + "%";
percentage +=1;
if (percentage <= 100) {
setTimeout(progress, stepSize);
}
}
}()), stepSize);
}
function start() {
var stepSize = 50;
setTimeout((function() {
var filler2 = document.getElementById("filler2"),
percentage = 0;
return function progress() {
filler.style.height = percentage + "%";
percentage +=1;
if (percentage <= 100) {
setTimeout(progress, stepSize);
}
}
}()), stepSize);
}
this is my html:
OPEN
<div id="light" class="white_content_stats">
<div class="prog">
<div id="filler" class="filler"></div>
</div>
</br>
<div class="prog2">
<div id="filler2" class="filler2"></div>
</div>
<a href = "javascript:void(0)" onclick = " document.getElementById('light').style.display='none';document.getElementById('fade').style.display='none'; ">
</br>CLOSE</a>
and this is my CSS:
.black_overlay_stats{
display: none;
position: absolute;
top: 0%;
left: 0%;
width: 100%;
height: 50%;
z-index:1001;
-moz-opacity: 0.6;
opacity:.70;
filter: alpha(opacity=70);
}
.white_content_stats {
display: none;
position:fixed;
top: 15%;
width: 300px;
padding: 30px;
margin-left:10px;
background-color:#F2F2F2;
border-radius: 0px;
box-shadow: 0px 0px 0px 20px rgba(0,0,0,0.6);
z-index:1002;
}
.prog {
height: 100px;
width: 30px;
border: 1px solid white;
position: relative;
}
.filler {
height: 0%;
width: 30px;
position: absolute;
bottom: 0;
background-color: grey;
}
.prog2 {
height: 100px;
width: 30px;
border: 1px solid white;
position: relative;
}
.filler2 {
height: 0%;
width: 30px;
position: absolute;
bottom: 0;
background-color: grey;
}

You define 2 functions with the same name start, so the second will be used and only it will be run, hence you can see only 1 progress bar works. You can modify the function start to make it accept an argument of id like this:
function start(id) {
//...
var filler = document.getElementById(id)
//...
}
Then call both start('filler') and start('filler2'):

Note that you should not use inline event property.
