I want to upload an H5P file to Moodle. I want this file to execute a JS code line (such as alert). Is it possible? What would it look like?
Thanks in advance.

I’m brand new to js, and tried to move every elements with certain class inside a certain div.
I made some research and saw a solution that works with id, but when I tried to change it to classNames it didn’t work anymore.
Is there anything more to write ?

Here is my HTML

<div class="bottom">bottom 1</div>
<div class="bottom">bottom 2</div>
<div id="top">top</div>

and my script so far

document.getElementById('top').appendChild(document.getElementsByClassName('bottom'))
console.log(document.getElementById('top').innerHTML)

I understood that appendChild didn’t work because document.getElementsByClassName(‘bottom’) is an array string instead of a node, but I have absolutely no idea what a node is, neither how to change my code for it to work.

I would really appreciate any help at all !
Thanks.

tester.mjs:

var instance = null;
export default class tester {
  constructor() {
   this.name = null;
  }
  static getInstance(){
    if(!instance){
      console.log("Creating instance")
      instance = new tester();
    }
    return instance;
  }
  
  setName(name) {
   this.name = name
  }
  
  getName() {
   return this.name
  }
}

file1.mjs:

import tester from './tester';
var obj = tester.getInstance();
obj.setName("seetha")

file2.mjs:

import tester from './tester';
var obj1 = tester.getInstance();
console.log(obj1.getName())

I am trying to set the name from file1.mjs and get the name from file2.mjs.First I run file1.mjs then it creates one javascript object for tester.mjs.Second I run file2.mjs then it again creating new javascript object for tester.mjs.But I want to use single javascript object of tester in both file1.mjs,file2.mjs and I want to run file1.mjs and file2.mjs independently.
Can anyone suggest me to achieve this.

My anchor link generated automatically:

<a class="" href="#Heading_3" title=">Heading 3</a>
<a class="" href="#%E3%81%A8%E3%80%81%E3%82%B2%E3" title=">ゲゲームのフ</a>

and anchor to

<h4><span class="" id="Heading_3"></span>Heading 3<span class=""></span></h4>
<h4><span class="" id="#%E3%81%A8%E3%80%81%E3%82%B2%E3"></span>ゲゲームのフ<span class=""></span></h4>

I use Javascrip & JQuery to smooth scrolling.

$('a[href^="#"]').on('click', function (e) {
    e.preventDefault();

    var target = this.hash;
    var $target = $(target);

    $('html, body').stop().animate({
        'scrollTop': $target.offset().top
    }, 900, 'swing', function () {
        window.location.hash = target;
    });
});

So, only heading 3 working ok, but link Japanese not working. How to scroll to link have Japanese smoothly?

In my html file i am passing value for –is-item-status as :-

<ion-label class="textColor label-md black-shade-light" style="--is-item-status: {{item.status}}" >{{item.status | formatEnum | async}}</ion-label>

(Note:- this is populated inside *ngFor condition).

in the browser i am able to see the value getting populated as :-

element.style{ --is-item-status: INVOICE_OPEN }

In my scss file i have code like :-

.textColor {
  @if var(--is-item-status) ==  'INVOICE_OPEN' {
    color: blue;
  } @else if var(--is-item-status) == ('PAYMENT_STATUS_CANCELLED'  or 'INVOICE_CANCELLED' or 'ORDER_CANCELLED') {
    color: red;
  } @else if var(--is-item-status) == ('PAYMENT_STATUS_PARTLY_APPLIED' or 'INVOICE_PARTLY_PAID' or 'ORDER_CLOSED') {
    color: black;
  } @else if var(--is-item-status) == ('PAYMENT_STATUS_APPLIED' or 'INVOICE_PARTLY_PAID' or 'ORDER_INVOICED') {
    color: green;
  }  @else {
    color: yellow;
  }
}

But the if conditions are not getting satisfied. Could someone tell me what am i doing wrong in this ?

I want to print path of object key, dynamically. Here is my code:

   const Tree = ({ data }) => {
     let path = "onboarding";
  
      return Object.keys(data).map((key) => {
        if (Array.isArray(data[key])) {
          path = path + "." + key;
          return (
              <Tree data={data[key]}></Tree> 
          );
        }

        if (typeof data[key] === "object") {
          path = path + "." + key;
          return (
              <Tree data={data[key]}></Tree>
          );
        } else {
          path = path + "." + key;    
          return (
            <input defaultValue={data[key]}
              style={{ fontWeight: "bold" }}
