html - Creat custom alert in JavaScript

Hey am new Web developer and am working on a quote website.

To understand clearly this question just visit my CodePen project below and just once click any copy button in the project. https://codepen.io/Akash11166666/pen/JjRzqzp

Did see my CodePen. As you can see I have created a custom copy alert which alerts you the text is copied but it will not vanish after some seconds.

I have tried many ways to solve this problem but none of them were useful.

My CodePen project for reference

My Javascript

<script>
const resultEl = document.querySelector('.allquotes');
const pageSize = document.querySelector('select[name="page-size"]');
const pageCurr = document.querySelector('input[name="page-curr"]')
const resultCount = document.querySelector('.result-count')
const pageNoCurr = document.querySelector('.page-no-curr');
const pageNoCount = document.querySelector('.page-no-count')
const btnFirst = document.querySelector('.page-btn-first');
const btnPrev = document.querySelector('.page-btn-prev');
const btnNext = document.querySelector('.page-btn-next');
const btnLast = document.querySelector('.page-btn-last');

let results = [];

const getResultCount = () => results.length;
const getPageSize = () => +pageSize.value;
const getCurrPage = () => +pageCurr.value;
const getPageCount = () => Math.ceil(getResultCount() / getPageSize());

const pageResponse = (records, pageSize, page) =>
  (start => records.slice(start, Math.min(records.length, start + pageSize)))
  (pageSize * (page - 1));

const main = async() => {
  btnFirst.addEventListener('click', navFirst);
  btnPrev.addEventListener('click', navPrev);
  btnNext.addEventListener('click', navNext);
  btnLast.addEventListener('click', navLast);
  pageSize.addEventListener('change', changeCount);

  results = await retrieveAllQuotes();
  updatePager(results);
  redraw();
};
const redraw = () => {
  resultEl.innerHTML = '';
  const paged = pageResponse(results, getPageSize(), getCurrPage());
  const contents = document.createElement('div');
  contents.innerHTML = paged.map(record => `<div class='latestatus'><p class='copytxt'>${record.quotes}</p><div> <button class="copystatus btn">Copy</button><span class="status-copy-alert hidden">Copied</span></div></div>`).join('');
  resultEl.append(contents);
};

const navFirst = (e) => {
  pageNoCurr.textContent = 1;
  pageCurr.value = 1;
  redraw();
}

const navPrev = (e) => {
  const pages = getPageCount();
  const curr = getCurrPage();
  const prevPage = curr > 1 ? curr - 1 : curr;
  pageCurr.value = prevPage;
  pageNoCurr.textContent = prevPage;
  redraw();
}

const navNext = (e) => {
  const pages = getPageCount();
  const curr = getCurrPage();
  const nextPage = curr < pages ? curr + 1 : curr;
  pageCurr.value = nextPage;
  pageNoCurr.textContent = nextPage;
  redraw();
}

const navLast = (e) => {
  pageNoCurr.textContent = getPageCount();
  pageCurr.value = getPageCount();
  redraw();
}

const changeCount = () => {
  updatePager();
  redraw();
};

const updatePager = () => {
  const count = getPageCount();
  const curr = getCurrPage();
  pageCurr.value = curr > count ? 1 : curr;
  pageNoCurr.textContent = curr > count ? 1 : curr;
  pageNoCount.textContent = count;
  resultCount.textContent = getResultCount();
};

const retrieveAllQuotes = async function() {

  // write your asynchronous fetching here

  return[{
      quotes: "1The cat is better than dog."
    },
    {
      quotes: "2Google is a open source library."
    },
    {
      quotes: "3Cats are better than ferrets."
    },
    {
      quotes: "4Love books."
    },
    {
      quotes: "5Life is short make it possible."
    },
    {
      quotes: "6The cat is better than dog"
    },
    {
      quotes: "7Google is a open source library."
    },
    {
      quotes: "8Cats are better than ferrets."
    },
    {
      quotes: "9Love books."
    },
    {
      quotes: "10Life is short make it possible."
    },
]; 
}
document.querySelector('.allquotes').addEventListener(

  'click',

  function (e) {

    e.preventDefault();
    

    if (e.target && e.target.matches('.copystatus')) {

        const quote = e.target.parentNode.closest('.latestatus')

            .childNodes[0].textContent;
      
      const notify = e.target.nextSibling.closest('.status-copy-alert');
      
      notify.classList.toggle('hidden');

        const textArea = document.createElement('textarea');

        textArea.value = quote;

        document.body.appendChild(textArea);

        textArea.select();

        document.execCommand('Copy');

        textArea.remove();

    }

  },

  false

);
main();

You are showing a tooltip (or "alert" as you call it) by removing (or actually toggling) its hidden class. You can hide it again by adding the hidden class back. You can do that after some time, e.g. 3 seconds, by using setTimeout().

notify.classList.toggle('hidden');

// New code below:

setTimeout(() => {
  notify.classList.add('hidden');
}, 3000);
