Get text from current element in autoplay carousel using javascript

I'm using Wow carousel in WordPress, and I want to get the text in the current element in the slider.
In Wow Carousel, the current slide takes the class center
My problem with the autoplay slider, the value stored in my variable doesn't change automatically
How can I fire the function when the class center is added automatically every time?
My code
<div id="testimonial-slider-5781" class="owl-carousel owl-loaded owl-drag">
<div class="owl-item active" style="width: 235.333px; margin-right: 15px;"><div class="testimonial-5781">
<h3> text </h3>
</div>
<div class="owl-item active" style="width: 235.333px; margin-right: 15px;"><div class="testimonial-5781">
<h3> text </h3>
</div>
<div class="owl-item active center" style="width: 235.333px; margin-right: 15px;"><div class="testimonial-5781">
<h3> text </h3>
</div>
<div class="owl-item" style="width: 235.333px; margin-right: 15px;"><div class="testimonial-5781">
<h3> text </h3>
</div>
</div>
jQuery(document).ready(function() {
function myFunction() {
let title = jQuery( "#testimonial-slider-5781 .center .testimonial-5781 h4" ).text();
jQuery("#service-title h3").text(title);
}
jQuery('.owl-prev').click(function(){
myFunction();
});
jQuery('.owl-next').click(function(){
myFunction();
});
});

You can listen to translated.owl.carousel event since it's triggered everytime carousel is translated, that would mean it's also triggered when class center is added to current slide.
Here is an example, do adapt to your own code as appropriate.
jQuery(document).ready(function() {
function myFunction() {
let title = jQuery("#testimonial-slider-5781 .center .testimonial-5781 h3").text();
jQuery("#service-title h3").text(title);
}
jQuery("#testimonial-slider-5781").on("translated.owl.carousel", function() {
myFunction();
});
});

scroll to next div by js

I know there are lots of same examples, but their code don't work. Please Help! So I have arrow Image at the bottom of container block. The content of container are flex( if it is important to know?!) And when i click on arrow, it should move down by next container.
$("#arrow").click(function() {
var $target = $('.container.active').next('.container');
if ($target.length == 0)
$target = $('.container:first');
$('html, body').animate({
scrollTop: $target.offset().top
}, 'slow');
$('.active').removeClass('active');
$target.addClass('active');
});
.container {
height: 100%;
margin: 0px;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="container first active" id="first">
///not important content
<button class="next">
<img src="arrow.png" id="arrow" alt="down">click
</button>
</div>
<div class="container second" id="second">
<div class="arrow">
<img src="arrowup.png" alt="up">
</div>
<div class="arrow">
<img src="arrow.png" alt="arrow">
</div>
</div>

You can simply use anchor tag and pass id of div you want to focus. Below is an example for that.
.container {
height: 100%;
margin: 0px;
}
.second, .first{
border : 1px solid black;
height : 500px;
width:100%
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="container first active" id="first">
<!-- not important content -->
<a href="#second">
<img src="arrow.png" id="arrow" alt="down">click
</a>
</div>
<div class="container second" id="second">
<a class="arrow" href="#first">
<img src="arrowup.png" alt="up">
</a>
<div class="arrow">
<img src="arrow.png" alt="arrow">
</div>
</div>

https://jsfiddle.net/w7duthsa/ Try this. U should be careful where arrow event fires. It is in icon. u have to click to icon to run. Button doesn't down.
$("#arrow").on("click", function(e) {
$(document).scrollTop($(this).parent().parent().next().offset().top);
return false; // prevent anchor
});
If u want to give up down to button then give arrow id to button and use function below https://jsfiddle.net/w7duthsa/1/
$("#arrow").on("click", function(e) {
$(document).scrollTop($(this).parent().next().offset().top);
return false; // prevent anchor
});

How to get link from an element and add to all elements of parent element using JavaScript

I have many divs with a class and every div contains diferent elements including a link.
what I want is to get the link and add it to all Elments of parent div such as img, headline etc. (using JavaScript)
Ex:
.myClass{
background-color:red;
display:inline-block;
width:150px;
overflow:hidden;
}
<div class="myClass">
<div></div>
<div></div>
<div><h1>test</h1></div>
<div><img src="https://scx1.b-cdn.net/csz/news/800/2019/2-nature.jpg" alt="">
Link1
</div>
</div>
<div class="myClass">
<div></div>
<div></div>
<div><h1>test</h1></div>
<div><img src="https://scx1.b-cdn.net/csz/news/800/2019/2-nature.jpg" alt="">
Link2
</div>
</div>

This is the fastest
Note I use function where I want to get at this or $(this)
$(function() { // on page load
$(".ecs-event").on("click", function() { // click any ecs-event container
location = $(this).find("a[rel=bookmark]").attr("href"); // find the bookmark
})
});
.myClass {
background-color: red;
display: inline-block;
width: 150px;
overflow: hidden;
}

how can I show a div based on content in another div jQuery

I have multiple divs in html such:
<div class="litter">
<div class="litter-1">
<div class="status">Available</div>
<div class="available"><img /></div>
</div>
<div class="litter-2">
<div class="status">Available</div>
<div class="available"><img /></div>
</div>
</div>
The status text will vary based on user input. If the status is available the available class should not show. But if the status is unavailable then it should. The image is present all the time but only displaying if the status changes.
I can get the jQuery to either hide all of the images, or show them all, but not based on the html value of the status.
jQuery
if($('.litter > .status').html()==="Available") {
$(this).next('.available').hide();
} else {
$('.available').show();
}
Any help?

You could use a loop using jQuery .each():
// change selector to '.litter .status'
$('.litter .status').each(function() {
// loop through each .status element
// get partner img container .available
var imgContainer = $(this).parent().find('.available');
if ($(this).text() === "Available")
{
imgContainer.hide();
}
else
{
imgContainer.show();
}
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/2.1.0/jquery.min.js"></script>
<div class="litter">
<div class="litter-1">
<div class="status">Available</div>
<div class="available"><img src="https://via.placeholder.com/150/" alt="placeholder1" /></div>
</div>
<div class="litter-2">
<div class="status">Other status</div>
<div class="available"><img src="https://via.placeholder.com/150/" alt="placeholder2" /></div>
</div>
</div>

You can toggle a single class, status-available, and combine it with the adjacent sibling combinator to control the display of the image.
<!-- Image will show -->
<div class="status status-available">…</div>
vs.
<!-- Image will not show -->
<div class="status">…</div>
Example
/* Image is hidden by default */
.available > img {
display: none;
}
/* Adjacent sibling combinator in action */
.status-available + .available > img {
display: block;
}
<div class="litter">
<div class="litter-1">
<div class="status status-available">Available</div>
<div class="available">
<img src="http://placekitten.com/150/150" alt="Cute cat" />
</div>
</div>
<div class="litter-2">
<div class="status">Available</div>
<div class="available">
<img src="http://placekitten.com/150/150" alt="Cute cat" />
</div>
</div>
</div>

Ok, so Haldo put me on the right track, but in order to make it all come together with the string. Instead of if ($(this).text() === ("Available") I had to use this if ($(this).text().indexOf('Needs a Forever Home') > -1)
The rest of the code stays the same as Haldo's.

Edit css of "item" when clicking on corresponding "btn"

So I have this
<div class="btns">
<div class="btn1"></div>
<div class="btn2"></div>
<div class="btn3"></div>
<div class="btn4"></div>
</div>
<div class="prevs">
<div class="pre1"></div>
<div class="pre2"></div>
<div class="pre3"></div>
<div class="pre4"></div>
</div>
http://jsfiddle.net/uzpxjukv/
You have btn1, btn2, btn3 and btn4. I'm trying to make it so that when you press btn1, the div with the class pre1 should then get "display: block;" or something to make it visible. Then when btn2 is clicked, pre1 turns invisible again and pre2 turns visible.

Maybe something like this? If there will be more buttons, it should be more optimalized.
$('.btns').find('div').click(function(){
$('.prevs').find('div').eq($(this).index()).toggle();
});
$('.btns').find('div').click(function(){
$('.prevs').find('div').eq($(this).index()).toggle();
});
.prevs div:not(.pre1) {
display:none;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="btns">
<div class="btn1">Button 1</div>
<div class="btn2">Button 2</div>
<div class="btn3">Button 3</div>
<div class="btn4">Button 4</div>
</div>
<div class="prevs">
<div class="pre1">Previews 1</div>
<div class="pre2">Previews 2</div>
<div class="pre3">Previews 3</div>
<div class="pre4">Previews 4</div>
</div>

JSFIDDLE DEMO -> http://jsfiddle.net/uzpxjukv/5/
$('.btns div').click(function() {
var classNumber = this.className.slice(-1);
$('.prevs div').hide();
$('.pre' + classNumber).show();
});
On click of the button div, first hide all the pre divs and then show only the relevant div.

Try it
$('.btns > div').on('click', function() {
var numberOfDiv = $(this).attr('class').slice('-1'),
prevs = $('.prevs');
prevs.find('> div').hide();
prevs.find('.pre' + numberOfDiv).show();
});
This example is with your html code, if is possible to change it, you can get a better code.

See the fiddle
I have changed your HTML a little bit..Changed the class attribute of the prevs divsti ids.
HTML
<div class="btns">
<div class="btn1" id="1" onClick="reply_click(this.id)"></div>
<div class="btn2" id="2" onClick="reply_click(this.id)"></div>
<div class="btn3" id="3" onClick="reply_click(this.id)"></div>
<div class="btn4" id="4" onClick="reply_click(this.id)"></div>
</div>
<div class="prevs">
<div id="pre1"></div>
<div id="pre2"></div>
<div id="pre3"></div>
<div id="pre4"></div>
</div>
JS
function reply_click(id) {
document.getElementById("pre" + id).style.display = "block";
}

Provided that you know what naming system the divs use, you could use something along these lines. (To see properly working, view using developer tool)
$('.btns div').on('click', function() {
var currClass = $(this).attr('class').slice(-1); //get end of number of div clicked
$('.prevs div').css('display', 'none'); //reset all divs to being hidden
$('.pre' + currClass).css('display', 'inline-block'); //show desired div
});
.btns div {
background-color: gray;
}
.btns div, .prevs div {
width: 2em;
height: 2em;
display: inline-block;
padding-right: 0.2em;
}
.prevs div {
background-color: red;
display: none;
}
