I wonder how I can highlight only the paragraph that at any moment correspondes to value retrieved from the input with a type of range.
When I move the slider I want to add a class to the paragraph which correspondes to the input value at that given time. I have achieved setting the class (I just used inline styling to test with), but how can I also at the same time remove the class from all the other paragraphs which don't correspond to the value?
This is what I got now:
<input id="part" type="range" min="1" max="6" value="6" step="1">
<p class="update-1">Lorem ipsum dolor sit amet, consectetur adipisicing elit. In nobis nemo porro saepe facere minus!</p>
<p class="update-2">Lorem ipsum dolor sit amet.</p>
<p class="update-3">Lorem ipsum dolor sit amet, consectetur adipisicing elit. Rem impedit neque odio, aut. Quos sapiente quisquam molestias, fugit iste aliquid, aperiam porro cumque quaerat pariatur obcaecati.</p>
<p class="update-4">Lorem ipsum dolor.</p>
<p class="update-5">Lorem ipsum dolor sit amet, consectetur adipisicing elit. Placeat, eius dolorum consectetur.</p>
<p class="update-6">Lorem ipsum dolor sit amet, consectetur adipisicing elit. Odio, dolore nesciunt nisi porro odit explicabo debitis? Iure qui, impedit fugiat officia itaque dolores. Laudantium.</p>
JS / jQuery:
var p = document.getElementById('part');
p.addEventListener('input', function () {
$('p.update-' + p.value).css('color', 'red');
}, false )
On the following example, when the range input moves, all <p> elements are changed to the .transparent class, then the selected one receives the new .selected class.
function highlight(){
var x = document.getElementsByTagName("p");
var i;
for (i = 0; i < x.length; i++) {
x[i].className = "transparent";
}
var sell = document.getElementById("parag").value;
document.getElementById("a" + sell).className = "selected";
}
body {
background: #f7f7f7;
}
.selected {
color: #000000;
background: rgba(215, 255, 0, 0.8);
}
.transparent {
color: #666666;
background: transparent;
}
<input id=parag type="range" name="range" min="1" max="6" step="1" oninput="highlight()">
<p id=a1 class="transparent">Lorem ipsum dolor sit amet, consectetur adipisicing elit. In nobis nemo porro saepe facere minus!</p>
<p id=a2 class="transparent">Lorem ipsum dolor sit amet.</p>
<p id=a3 class="transparent">Lorem ipsum dolor sit amet, consectetur adipisicing elit. Rem impedit neque odio, aut. Quos sapiente quisquam molestias, fugit iste aliquid, aperiam porro cumque quaerat pariatur obcaecati.</p>
<p id=a4 class="transparent">Lorem ipsum dolor.</p>
<p id=a5 class="transparent">Lorem ipsum dolor sit amet, consectetur adipisicing elit. Placeat, eius dolorum consectetur.</p>
<p id=a6 class="transparent">Lorem ipsum dolor sit amet, consectetur adipisicing elit. Odio, dolore nesciunt nisi porro odit explicabo debitis? Iure qui, impedit fugiat officia itaque dolores. Laudantium.</p>
An alternative solution only using javascript and reducing the number of operations is:
// save the previous selected paragraph
var oldSelectedParagraph = null;
window.onload= function(e) {
document.getElementById('part').addEventListener('change', function () {
// if the previous selected paragraph exists remove the attribute
if (oldSelectedParagraph != null) {
oldSelectedParagraph[0].style.color = '';
}
//save current selected paragraph if valid and set the attribute
oldSelectedParagraph = document.querySelectorAll('p.update-' + this.value);
if (oldSelectedParagraph.length == 1) {
oldSelectedParagraph[0].style.color = 'red';
} else {
oldSelectedParagraph = null;
}
}, false )
}
<input id="part" type="range" min="1" max="6" value="6" step="1">
<p class="update-1">Lorem ipsum dolor sit amet, consectetur adipisicing elit. In nobis nemo porro saepe facere minus!</p>
<p class="update-2">Lorem ipsum dolor sit amet.</p>
<p class="update-3">Lorem ipsum dolor sit amet, consectetur adipisicing elit. Rem impedit neque odio, aut. Quos sapiente quisquam molestias, fugit iste aliquid, aperiam porro cumque quaerat pariatur obcaecati.</p>
<p class="update-4">Lorem ipsum dolor.</p>
<p class="update-5">Lorem ipsum dolor sit amet, consectetur adipisicing elit. Placeat, eius dolorum consectetur.</p>
<p class="update-6">Lorem ipsum dolor sit amet, consectetur adipisicing elit. Odio, dolore nesciunt nisi porro odit explicabo debitis? Iure qui, imped</p>

jQuery
<script>
//Read more button
var parsToHide = 3;
var initReadMore = function() {
$('#hs_cos_wrapper_petition-area-module-2_').children().each(function( index, element ) {
if ( index == parsToHide + 5) {
console.log("Logging from read more function");

console.log($('.read-more-btn').text() == 'READ MORE' ? 'READ LESS' : 'READ MORE');
}
document.addEventListener("DOMContentLoaded", () => {
initReadMore();
});
Above is my script. I am essentially trying to get my button to show Read Less once clicked and then show Read more when clicked again. Essentially toggling the text. I've done a ternary check in my readMore function but in the log, it shows "READ MORE" every time it's clicked. It doesn't toggle between "READ LESS" and "READ MORE".
Any idea why?
I am trying to toggle the text for my button. It seems correct but the toggle wont occur.
I've created some clickable tabs but for some reason the tab content does not display on click. I can't see anything out of place with my code. Any ideas would be greatly appreciated. Thanks.

const tabs = document.querySelectorAll('[data-tab-target]');
const tabContents = document.querySelectorAll('[data-tab-content]');
tabs.forEach(tab => {
tab.addEventListener('click', () => {
const target = document.querySelector(tab.dataset.tabTarget)
tabContents.forEach(tabContents => {

tabs.forEach(tab => {

you can keep a variable with the selected tab, and go from there, also it's better to have only one listener on your tablist, i would set an id to <ul class="tablist"> for faster select.. something like this:
const tabs = document.getElementById("tablist");
let selected = document.querySelectorAll("[data-tab-target]")[0];
const tabContents = document.querySelectorAll("[data-tab-content]");
let selectedContent = tabContents[0];
tabs.addEventListener("click", (e) => {
selected.classList.remove("active-tab");
selected = e.target;
selected.classList.toggle("active-tab");
const index = [...selected.parentNode.children].indexOf(selected);
selectedContent.classList.remove("active-tab");
selectedContent = tabContents[index];
selectedContent.classList.toggle("active-tab");
});
.active-tab {
color: red;
}
<div class="container-tabs">
<ul class="tablist" id="tablist">

you need to consider the border so add box-sizing: content-box; and also 1px to the final width (I am finding why ...)
$.each($('button'), (i, v) => {
$(v).css('width', ($(v).find('span').outerWidth() + 1) + 'px');
$(v).css('top', i * 100 + 'px');
});
section {
position: relative;
width: 300px;
}
button {
position: absolute;
box-sizing: content-box;
padding: 0;
text-align: left;
}
span {

I am struggling to figure this out. I have a div that is set to overflow: scroll;. I want to be able to click a link and have the content in that div scroll to the top of the linked element. For some reason it always seems like it scrolls until the top of the element hits the top of the body. I need it to stop when it hits the top of the overflow div. In the example I have below when you click "link to paragraph 3" I need it to put paragraph 3 at the top of the scrollable div.
$(document).ready(function(){
$("a").click(function(e){
e.preventDefault();
var anchor = $(this).attr("href");
console.log(anchor);
$(".parent").animate({
scrollTop: $(anchor).offset().top - $(".parent").offset().top
}, 2000);
});
});
body {background-color:tan;}
.parent {height:100px; overflow-y:scroll; background-color:#ffff; margin-top:100px;}

jQuery's .offset() method returns the offset of the element relative to the document. To counteract this, you need to substract the offset of the container. Below I have modified the 4th line of javascript only.
$(document).ready(function(){
$("a").click(function(e){
e.preventDefault();
var anchor = $(this).attr("href");
console.log(anchor);
$(".parent").animate({
scrollTop: $(".parent").scrollTop() + $(anchor).offset().top - $(".parent").offset().top
}, 2000);
});
});

background-color:tan;

So I when I start scrolling into my div, my initial value is 0. When I reach the bottom of the div, I want my value to be 100.
Here's an example :
var initial = 0;
var end = 100;
$('div').scroll(function() {
initial++;
console.log(initial);
});
div {

In this example, if you check the console, When I scroll, the last value is 5, I want it to be 100
Thanks for your help !
You can set initial to be the percentage of the scrollable height
var $test = $('.test');
var scrollableHeight = $test.height() - $test[0].scrollHeight; // get amount of scroll available
$test.scroll(function() {
var $this = $(this);
var initial = $this.scrollTop() / scrollableHeight * -100; // divide the scroll top by the amount of scrollable height to get the percentage then times by -100 to make it a positive number out of 100
console.log(parseInt(initial)); // parseInt is optional - just gives you integers
});
.test {
width: 200px;
height: 300px;
border: 1px solid;
overflow-y: scroll;
background-color: #fff;
