get the second child element using javaScript

Alright, I am working on a school assignment where I have 4 containers. When you click a button in a container, a popup shows the image and heading of the container you clicked on. I have figured out how to get the image to display, but I'm struggling with getting the heading, which is the second child element in the container. Unfortunately, I can only use HTML, CSS and JavaScript for this assignment. I'm new to this, so please be patient and kind. Here is my code, any help would be greatly appreciated.

document.getElementById('bigImage').src = 
this.parentNode.firstElementChild.src;

document.getElementById('title').textContent = 
this.parentNode.secondElementChild.textContent;
javascripthtmlcss

Answer №1

let mainElement = document.getElementById('largePic');
let parentEl = mainElement.parentNode;
parentEl.children[0]; // <- the first child
parentEl.children[1]; // <- the second child

Answer №2

This task does not require any coding on your part.

this.parent().nextElementSibling

Unfortunately, the above code is incorrect. Please take some time to review and understand NonDocumentTypeChildNode.nextElementSibling to determine its relevance to your issue.

Answer №3

Using JavaScript to Target and Modify the Second Element in an Unordered List

document.querySelector('ul').children[1].innerHTML = "Description";

Keep in mind that adjusting the index number within the children array will allow you to target different elements.
