So I want to know how do I get count of parent child child childs for example:
const parent = document.querySelectorAll('.parent'); parent.forEach(el => { const ul = el.querySelector('.child3-child'); const div = document.createElement('div'); div.textContent = ul.childNodes.length; el.append(div); });
<div class="parent"> <div class="child1"> text </div> <div class="child2"> text </div> <div class="child3"> <ul class="child3-child"> <li> some text... </li> <ul> </div> </div>
And now I want count how many <ul class="child3-child">
has child elements in this case it has only 1 li
.
children
instead of childNodes
. The former includes HTML Elements while the latter includes text nodes.</ul>
tag properly or else the borwser will think it's opening a nested element. const parent = document.querySelectorAll('.parent'); parent.forEach(el => { const ul = el.querySelector('.child3-child'); const div = document.createElement('div'); div.textContent = ul.children.length; el.append(div); });
<div class="parent"> <div class="child1"> text </div> <div class="child2"> text </div> <div class="child3"> <ul class="child3-child"> <li> some text... </li> </ul> <!--- This wasn't properly closed --> </div> </div>
