html - Creat custom alert in JavaScript

Question

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 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) => {

  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;

document.querySelector('.allquotes').addEventListener(

  'click',

  function (e) {

    e.preventDefault();
    

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

      const notify = e.target.nextSibling.closest('.status-copy-alert');

copy alert which alerts you the text is copied but it will not vanish after some seconds.

I hartley thanks for those who answer this question.

Answer 1

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);
