7,255 PointsWhy is my down button not working?
I cant fix it
const toggleList = document.getElementById('toggleList'); const listDiv = document.querySelector('.list'); const descriptionInput = document.querySelector('input.description'); const descriptionP = document.querySelector('p.description'); const descriptionButton = document.querySelector('button.description'); const listUl = listDiv.querySelector('ul'); const addItemInput = document.querySelector('input.addItemInput'); const addItemButton = document.querySelector('button.addItemButton');
listUl.addEventListener('click', (event) => { if (event.target.tagName == 'BUTTON') { if (event.target.className == 'remove') { let li = event.target.parentNode; let ul = li.parentNode; ul.removeChild(li); } if (event.target.className == 'up') { let li = event.target.parentNode; let prevLi = li.previousElementSibling; let ul = li.parentNode; if (prevLi) { ul.insertBefore(li, prevLi); } } if (event.target.className === 'down'){ let li = event.target.parentNode; let nextLi = li.nextElementSibling; let ul = li.parentNode; if(nextLi){ ul.insertBefore(li,nextLi); } } } });

if (event.target.className == 'down'){
let li = event.target.parentNode;
let nextLi = li.nextElementSibling;
let ul = li.parentNode;
if(nextLi){
ul.insertBefore(li,nextLi); //<--------reversed
}
}
It should be
ul.insertBefore(nextLi, li);
