Use vertical tab toggle multiple times - javascript

i need a toggle-tab-section with a vertical tab-menu.
I started with the base script of w3schools: https://www.w3schools.com/howto/tryit.asp?filename=tryhow_js_vertical_tabs
and customized and improved it.
Now i have the problem, that i need this toggle-section multiple times on one site. So i created a parent div around the section with an unique id.
For the script now i need to get only the elements in this parent, so i tried to call them with the parent instead of "document" but this wont work for me.
function toggleTabs(evt, tabID, itemID) {
var i, tabcontent, tablinks, wrapper;
wrapper = document.getElementById('item' + itemID);
tabcontent = wrapper.getElementsByClassName("tabcontent");
for (i = 0; i < tabcontent.length; i++) {
tabcontent[i].style.display = "none";
}
tablinks = wrapper.getElementsByClassName("tablinks");
for (i = 0; i < tablinks.length; i++) {
tablinks[i].className = tablinks[i].className.replace(" active", "");
}
wrapper.getElementById(tabID).style.display = "block";
evt.currentTarget.className += " active";
}
Single tabsection (working) https://jsfiddle.net/029mua5h/
Multiple tabsection (not working) https://jsfiddle.net/029mua5h/1/


wrapper.getElementById(tabID).style.display = "block"; does not work. This is because .getElementById is not a prototype of a single element. Since id's are meant to be unique, it does not make sense to look for an id inside an element, because we know that there can only be one element with a spesific id. therefore we have to use the proper
document.getElementById(tabID).style.display = "block";
function toggleTabs(evt, tabID, itemID) {
var i, tabcontent, tablinks, wrapper;
wrapper = document.getElementById('item' + itemID);
tabcontent = wrapper.getElementsByClassName("tabcontent");
for (i = 0; i < tabcontent.length; i++) {
tabcontent[i].style.display = "none";
}
tablinks = wrapper.getElementsByClassName("tablinks");
for (i = 0; i < tablinks.length; i++) {
tablinks[i].className = tablinks[i].className.replace(" active", "");
}
document.getElementById(tabID).style.display = "block";
evt.currentTarget.className += " active";
}

How to change the color of the header when scrolling down the page?

The site has several sections. The first one with a picture, on it header should be transparent. The following blocks are colored and on them the header must take the color of the block. How can I achieve this?
I wrote code to change the header from transparent to the color of the second block, but I think there is a better solution than writing this for each block, but I can't find it.
$(function() {
let header = $('.header'),
intro = $('.intro');
$(window).scroll(function() {
if ($(this).scrollTop() > intro.outerHeight()) {
header.addClass('header_filled');
} else {
header.removeClass('header_filled');
}
});
});

In order to determine wether the header block is above any of your blocks that change its color, you need to check if the header position + height "touches" the top edge of the element. After that you can simply apply the background color of the "touched" element to your header.
$(window).scroll(function(){
var $header = $(".header");
var header_position = $header.offset().top;
var header_height = $header.outerHeight();
$('.header-color').each(function(){
var color_block_position = $(this).offset().top;
if (header_position + header_height >= color_block_position) {
$header.css({
'background-color': $(this).css('background-color')
});
}
});
});
.header {
background-color: #CECECE;

jquery animate not working on first click

I'm trying to implement Read More button with animation. Animation working fine after the first click but on the first click, it seems that the animation method doesn't come into consideration.
JSFiddle link for the below code.
Here is my code:
var text = $('.content')
const originalHeight = text.height();
$(".show-more a").on("click", function() {
var $this = $(this);
var $content = $this.parent().prev("div.content");
var linkText = $this.text().toUpperCase();
var fullHeight = text[0].scrollHeight;
if (linkText === "SHOW MORE") {
linkText = "Show less";
$content.addClass('showContent').removeClass('hideContent');
text.animate({
'height': fullHeight
});
} else {
linkText = "Show more";
$content.addClass('hideContent').removeClass('showContent');
text.animate({
'height': originalHeight
});
};
$this.text(linkText);
});
div.text-container {

Javascript === is a case sensitive comparison. Your code is if (linkText === "SHOW MORE") where your main text is Show more. Thats all.

I would need something like this:
http://www.laurelhalo.com/
The main area should keep its width while hovering one of the two sidebars, and push off on one side. There also should be a sliding animation, like in the example.
How is it possible to realize that? Is it possible with jQuery?
Would be very thankful for help. :)

Just add min-width:100%; to your main-area class.
$(".left-area").mouseenter(function() {
$(".left-area-content").show();
$(".left-area-content-preview").hide();
}).mouseleave(function() {
$(".left-area-content").hide();
$(".left-area-content-preview").show();
});
$(".right-area").mouseenter(function() {
$(".right-area-content").show();
$(".right-area-content-preview").hide();

$(".right-area-content").hide();
$(".right-area-content-preview").show();

Bootstrap 4 sticky-top change Navbar color

To get a sticky navbar I used the Bootstrap 4 class sticky-top. I prefer the css solution instead of some JS, because that made some errors in the past.
I want to have my navbar in a transparent color when the user reaches it. (The moment my navbar gets sticky - that works). Before that it should have a random color. (That does not work - The grey background emerges from the transparent background of the sticky-top class).
I have not found a good solution to get this yet. I have tried to add a new class via JS, but that did not work.
Codepen example
/* Open tabs */
function openTab(evt, parameter) {
var i, tabcontent, tablinks;
tabcontent = document.getElementsByClassName("tabcontent");
for (i = 0; i < tabcontent.length; i++) {
tabcontent[i].style.display = "none";
}
tablinks = document.getElementsByClassName("tablinks");
for (i = 0; i < tablinks.length; i++) {
tablinks[i].className = tablinks[i].className.replace(" active", "");
}
document.getElementById(parameter).style.display = "block";
evt.currentTarget.className += " active";
}
/* Open tabs END */
/* Smooth scroll */
//Only where the class smooth-scroll is, scrolling is enabled
$(document).ready(function () {
$('a.smooth-scroll[href*="#"]:not([href="#three"])').click(function () {
if (location.pathname.replace(/^\//, '') == this.pathname.replace(/^\//, '') && location.hostname == this.hostname) {
var target = $(this.hash);
//Comment the following line if you don't want to see the anchor in the url
//target = target.length ? target : $('[name=' + this.hash.slice(1) + ']');
if (target.length) {
$('html, body').animate({
scrollTop: target.offset().top
}, 1000);
return false;
}
}
});
});

For reasons explained here position:sticky (Bootstrap sticky-top) doesn't provide an indication of when it's "stuck".
Therefore, you need to use JS to conditionally change the Navbar color/style.
One way is using an IntersectionObserver. You can use this on the #nav-anker which is the element immediately before the sticky-top Navbar.
(new IntersectionObserver(function(e,o){
if (e[0].intersectionRatio > 0){
document.documentElement.removeAttribute('class');
} else {
document.documentElement.setAttribute('class','stuck');
};
})).observe(document.querySelector('#nav-anker'));
So when the Navbar becomes sticky, the stuck class is added to it. You can have CSS styles that change when it's stuck...
/* style for when sticky is applied */
.stuck .sticky-top {
background: #000;
}
Demo: https://www.codeply.com/go/psiFbB6Ro6

You can simply override the color of all "nav" styles.
Even tho it's not recommended to use "!important", this will work here.
Otherwise you will need to set up the style of all parents till the nav bar ancestor or pass an ID to the nav bar.
EDIT: By checking the offset of the element to the topside (which is 0 if it is sticky) you can change the opacity to whatever value you want.
So if the offset to top is 0 you lower the opacity and if the offset is greater than 0 you simply revert the opacity back to 1.

Justify paragraphs by changing the word-spacing

Is there a smart way to justify paragraphs inside a fixed-width div tag without wrapping and only changing the word-spacing? See link below.
Cheers
https://jsfiddle.net/TheCoder/zhL895x9/embedded/result/
<style>
div {
border: 1px solid black;
width: 800px
}
p {
font-size:20px;
white-space: nowrap;
}
#par1 {
word-spacing: -21px;
}
#par2 {
word-spacing: 31px;
}
#par3 {
word-spacing: 10.5px;
}
</style>
<div>
<p id="par1">Lorem ipsum dolor sit amet, consetetur sadipscing elitr, sed diam nonumy eirmod tempor invidunt ut labore et dolore magna aliquyam erat, sed diam voluptua.</p>
<p id="par2">At vero eos et accusam et justo duo dolores et ea rebum.</p>
<p id="par3">Stet clita kasd gubergren, no sea takimata sanctus est Lorem ipsum dolor sit amet.</p>
</div>

from
#par1 {
word-spacing: -21px;
}
to
#par1 {
white-space:pre-line;
}
