How to select an element inside another element | JavaScript

var el = document.getElementById("search-field");

This will give you an element with the id attribute set to "search-field".

Let's say that you have a div with a div inside. This div has multiple divs inside it and you want to select some of them.

var products = document.getElementById("products-wrapper").querySelectorAll(".product");
