JavaScript JavaScript and the DOM (Retiring) Getting a Handle on the DOM Practice Selecting Elements

Posted by nimishhathalia2

Selecting indirect descendant elements from the document.

I need help with the below code.

I've looked at MDN, StackOverflow, W3Schools and other resources, understood how to use multiple CSS selectors using querySelectorAll() method. However, it's still not working.

To test around and see if other methods would work, I tried out parentNode notation and other possibilities, but to no avail.

Please help!

js/app.js 
let navigationLinks = document.querySelectorAll("nav li");
let galleryLinks;
let footerImages;
index.html

The method is fine, but the instructions ask you to "select all links inside the <nav> element" and this code is selecting list items instead.

Links are implemented with anchor (a) elements.

Hi Steven, I can't imagine why I ended up in this situation where I took 'li' as links. This resolved my issue.

Thanks a lot.

Cheers, Nimish.

You might take comfort in knowing that based on other forum questions, this is actually a common mistake. I guess it's because most tag names have letters in common with the names used to describe them. But mistakes are often the best teachers, so you'll most likely remember this exception now!

Happy coding.

Perhaps that more enlightening than comforting! But in retrospect, I still can't believe I did that. It seems so trivial that it's nearly impossible to miss.

Thanks again.
