html not appending to the carousel on popover

I Am Trying to make a popover with a bootstrap carousel and where the carousel items are to be generated and appended from a script but I get the carousel but I am unable to append the item. I tried hard but I didn't come up with a solution.
the HTML initialized is as below
HTML:
<div class="popup" data-popup="popup-1">
<div class="popup-inner">
<i class="fas fa-bars"></i>
<div class="frame">
<div id='carousel' class='carousel slide' data-bs-ride='carousel'>
<div class='carousel-inner items-slider1'>
</div>
</div>
</div>
</div>
</div>
the script I have tried was
Javascript:
function findallchord(currentchord , currenttype) {
for (let i = 1; i < 10; i++) {
if (Raphael.chord.find(currentchord ,currenttype,i)) {
Raphael.chord("div3", Raphael.chord.find(currentchord , currenttype,i), currentchord +' ' +currenttype).element.setSize(75, 75);
}
}
}
var getChordRoots = function (input) {
if (input.length > 1 && (input.charAt(1) == "b" || input.charAt(1) == "#"))
return input.substr(0, 2);
else
return input.substr(0, 1);
};
$('.popup').on('shown.bs.popover', function () {
$('.carousel-inner').carousel();
});
$('[data-bs-toggle="popover"]').popover({
html: true,
content: function() {
return $('.popup').html();
}}).click(function() {
var oldChord = jQuery(this).text();
var currentchord = getChordRoots(oldChord);
var currenttype = oldChord.substr(currentchord.length);
findallchord(currentchord , currenttype);
var chordsiblings = $('#div3').children().siblings("svg");
for (let i = 1; i < 10; i++) {
if (Raphael.chord.find(currentchord , currenttype,i)) {
var itemid = "chord" + i;
var theDiv = "<div class='carousel-item"+((itemid=="chord1") ? ' active':'')+" ' id='"+currentchord+''+itemid+"'> "+chordsiblings[i-1].outerHTML+" </div>";
$('.items-slider1').append(theDiv);
}
}
});
I have also tried appendTo also as
$(theDiv).appendTo('.items-slider1');
Please Help to solve this
This is the output I get, the appended elements are not in the carousel
Note: I am using Bootstrap 5

Try instantiating the carousel after you've set it up
/*
$('.popup').on('shown.bs.popover', function () {
$('.carousel-inner').carousel();
});
*/
$('[data-bs-toggle="popover"]').popover({
html: true,
content: function() {
return $('.popup').html();
}}).click(function() {
var oldChord = jQuery(this).text();
var currentchord = getChordRoots(oldChord);
var currenttype = oldChord.substr(currentchord.length);
findallchord(currentchord , currenttype);
var chordsiblings = $('#div3').children().siblings("svg");
for (let i = 1; i < 10; i++) {
if (Raphael.chord.find(currentchord , currenttype,i)) {
var itemid = "chord" + i;
var theDiv = "<div class='carousel-item"+((itemid=="chord1") ? ' active':'')+" ' id='"+currentchord+''+itemid+"'> "+chordsiblings[i-1].outerHTML+" </div>";
$('.items-slider1').append(theDiv);
}
}
$('.carousel-inner').carousel();
});

It was needed to do call the click function first before popover as below
$('[data-bs-toggle="popover"]').click(function() {
var oldChord = jQuery(this).text();
var currentchord = getChordRoots(oldChord);
var currenttype = oldChord.substr(currentchord.length);
findallchord(currentchord , currenttype);
var chordsiblings = $('#div3').children().siblings("svg");
for (let i = 1; i < 10; i++) {
if (Raphael.chord.find(currentchord , currenttype,i)) {
var itemid = "chord" + i;
var theDiv = "<div class='carousel-item"+((itemid=="chord1") ? ' active':'')+" ' id='"+currentchord+''+itemid+"'> "+chordsiblings[i-1].outerHTML+" </div>";
$('.items-slider1').append(theDiv);
}
}
}).popover({
html: true,
content: function() {
return $('.popup').html();
}});

next and previous JSON data with javascript

I' would like to create Next/Previous buttons for json array, but I can't get it to work.
This is the last one I have tried
<div id="text"></div>
<button name="prev">go to previous div</button>
<button name="next">go to next div</button>
<script>
myFunction([
{
"text": "text0"
},
{
"text": "text1"
},
{
"text": "text2"
},
{
"text": "text3"
}
]);
function myFunction(arr) {
var out = "";
var i ;
out = '<p>' + arr[i].text + '</p> <br>';
document.getElementById("text").innerHTML = out;
}
</script>

You can convert json data to string or better say html with $.each like below. as you tagged jQuery, here is jQuery approach:
myFunction([{
"text": "text0"
},
{
"text": "text1"
},
{
"text": "text2"
},
{
"text": "text3"
}
]);
function myFunction(arr) {
$.each(arr, function(i, v) {
$('#text').append('<div>' + v.text + '</div>');
});
}
var divs = $('.mydivs>div');
var now = 0;
divs.hide().first().show();
$("button[name=next]").click(function(e) {
divs.eq(now).hide();
now = (now + 1 < divs.length) ? now + 1 : 0;
divs.eq(now).show();
});
$("button[name=prev]").click(function(e) {
divs.eq(now).hide();
now = (now > 0) ? now - 1 : divs.length - 1;
divs.eq(now).show();
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="text" class="mydivs"></div>
<button name="prev">go to previous div</button>
<button name="next">go to next div</button>

<div id="text">
</div>
<script>
var i = 0;
let arr = [
{
"text": "text0"
},
{
"text": "text1"
},
{
"text": "text2"
},
{
"text": "text3"
}
];
setInterval(function myFunction() {
var out = "";
out = '<p>' + arr[i].text + '</p> <br>';
document.getElementById("text").innerHTML = out;
console.log(out);
if (i < arr.length - 1) {
i += 1;
} else {
i = 0;
}
}, 1000)
</script>

User inputs information into text box which makes allows user to select multiple words and creates different Titles based on the selections

I am gaining user input from four different areas and I want to take those options and convert them to an array which will loop through and display different variations of the words selected. The problem I am having is that the array will not cycle through the variables when passed through it unless they are already pre-defined.

Variable value is not being cleared

This code displays parsed data from php the problem is when I select another set of data which are the parsed the previous data are not being cleared. I have tried emptying the var json but without any positive result.
$(document).ready(function() {
$(".chooseSub").on("click",function(event) {
event.preventDefault();
var display = $(this).attr("title");
var idx = 0;
$.post("includes/learnFunctions.php", {
learnThis:display
}, function(data) {
var json = $.parseJSON(data);
if (json == 0) {
$("#spanQ").html("Nothing to show!");
} else {
workData(json, idx);
}
});
});
function workData(json, idx){
function next() {
if (idx > (json.length - 1)) {
idx = 0;
}
console.log(idx+" next() start");
var text1 = json[idx].question;
var text2 = json[idx].answer;
$("#spanQ").html("<p>" + text1 + "</p>");
$("#spanA").html("<p>" + text2 + "</p>");
console.log(idx,text1,json);
console.log(json );
idx++;
}
$(".test").on("click",function(){
next();
});
}
}); //doc ready

I have tried couple of different approaches but none of them is working for the interval scenario.
$(document).ready(function() {
var idx = 0;
function workData(custVar){
clearInterval(myInterval);
function again(){
if (idx > (custVar.length - 1)) {
idx = 0;
}
text1 = custVar[idx];
$("#spanQ").html("<p>" + text1 + "</p>");
console.log(idx,text1,custVar);
idx++;
}
var myInterval = setInterval(again, 2000);
}
function manStep(custVar){
if (idx > (custVar.length - 1)) {
idx = 0;
}
text1 = custVar[idx];
$("#spanQ").html("<p>" + text1 + "</p>");
console.log(idx,text1,custVar);
idx++;
};
var customVar1 = ["green", "black", "red", "blue", "yellow"];
var customVar2 = ["one","two", "three", "four", "five"];
$("#id1").on("click", function(){
workData(customVar1);
});
$("#id2").on("click", function(){
workData(customVar2);
});
$("#id3").on("click", function(){
clearInterval(interval);
var interval = setInterval(function(){manStep(customVar1);}, 2000);
});
$("#id4").on("click", function(){
clearInterval(interval);
var interval = setInterval(function(){manStep(customVar2);}, 2000);
});
}); //doc ready

If you add an event handler with $(".test").on("click", ...), this does not cause any previous handlers to be removed. Instead, every run of workData() registers an additional action to carry out on clicking the .test element. This is why you are seeing as many log outputs as calls to workData() were made.
To get rid of this problem, you should remove any existing "click" event handler before adding a new one. jQuery offers the off() function for this purpose:
var test = $(".test");
test.off("click");
test.on("click", ...);
// or: test.off("click").on("click", ...)

slideUp() all the elements but not the selected ones

All I want to do is:
there are 7 numbers and 7 divs, they are linked to each other (nr 0 it's in a relationship with div 0)
when one of the numbers is clicked, it should collapse all the other divs which are not selected
it can be selected more at one time
To sum up, basically, the page has some labels with numbers and 7 divs which are all displayed by default (the divs), but when one or more of them are chosen by clicking on the numbers, the page should display only the chosen divs.
This is what I've been trying to do:
for(var i = 0; i <= 6; i++) {
if(i != (floors[i])) {
$("#lvl" + floors[i]).slideUp();
}
}
More code:
http://jsfiddle.net/LSjg4/

Try
var floors = [];
var $lvls = $('.lvl'), $nrs = $(".nr");
$nrs.click(function () {
var $nr = $(this), index = $nrs.index($nr), $lvl = $lvls.eq(index);
$lvl.add($nr).toggleClass('active');
if($nr.hasClass('active')){
$lvls.not('.active').slideUp();
$lvl.slideDown();
$nr.css("background-color", "#1b7664");
$nr.css("border-color", "#236959");
floors.push(($nr).text());
} else {
$nr.css("background-color", "#02c099");
$nr.css("border-color", "#13a480");
if($nrs.filter('.active').length == 0){
$lvls.slideDown();
} else {
$lvls.not('.active').slideUp();
}
var text = $nr.text();
floors.splice($.inArray(text, floors), 1);
}
console.log('floors', JSON.stringify(floors))
});
Demo: Fiddle

I corrected a few things in your code. Here is the below working code and link to it in jsfiddle.
There was a data type mismatch(comparing string and int). When matching whether it exists in floors array, the code was checking floors[i] only whereas the i can be any position in floors.
var floors = [];
$(".nr").click(function () {
var state = $(this).data('state');
state = !state;
if (state) {
$(this).css("background-color", "#1b7664");
$(this).css("border-color", "#236959");
floors.push(parseInt($(this).text()));
console.log(floors);
for(var i = 0; i <= 6; i++) {
ret = $.inArray(i, floors);
if(ret==-1) {
$("#lvl" + i).slideUp();
}
else {
$("#lvl" + i).slideDown();
}
}
} else {
$(this).css("background-color", "#02c099");
$(this).css("border-color", "#13a480");
for (var i = 0; i < floors.length; i++) {
if (floors[i] == parseInt($(this).text()))
floors.splice(i, 1);
}
for(var i = 0; i <= 6; i++) {
ret = $.inArray(i, floors);
if(ret==-1) {
$("#lvl" + i).slideUp();
}
else {
$("#lvl" + i).slideDown();
}
}
}
$(this).data('state', state);
});

I believe this is what you're looking for:
$(".nr").click(function () {
$(this).toggleClass('selected');
$('.nr').each(function(){
var $target = $('#lvl'+$(this).text());
if($(this).is('.selected'))
$target.slideDown();
else
$target.slideUp();
});
});
Note that instead of changing the CSS properties I set up a class for the selected elements
Demo fiddle

Try this
$(".nr").click(function () {
//alert($(this).attr("data-select"));
if($(this).attr("data-select") === "1") {
$(this).attr("data-select","0");
} else {
$(this).attr("data-select","1");
}
$(".nr").each(function(){
if($(this).attr("data-select") === "1") {
var id = $(this).text();
$("div#lvl"+id).slideDown();
} else {
var id1 = $(this).text();
$("div#lvl"+id1).slideUp();
}
});
});
