Adding a class to an element without using an ID or existing class in JavaScript

Just starting out... :)

I'm working on this code snippet:

<div class="menu">
  <ul>
    <li></li>
    ...
  </ul>
</div>

I want to add the class "nav" to the <ul> element so it looks like this: <ul class="nav">

Any assistance on how to use "GetElementByClass"? I'm a bit lost.

Answer №1

Here is the solution provided:

const menu = document.querySelector('.menu > ul').classList.add('nav');
<div class="menu">
  <ul>
    <li></li>
    ...
  </ul>
</div>

The approach taken was to target the specific <ul /> element using CSS and then apply a class using Javascript's classList API.

Answer №2

If the first unordered list is the only one on the page, you can implement this snippet

document.querySelector('ul').classList.add("nav")
