Introduction
The querySelectorAll() method allows you to find and gather elements in the DOM that match a specified CSS selector. It's like creating a collection of misfit toys, only with HTML elements!
Example 1: Select All the Paragraphs
const allParagraphs = document.querySelectorAll('p');
console.log(allParagraphs);
// Result: A list of all the <p> elements on the page
Now you have a collection of paragraphs, just like a stand-up comedian has a collection of jokes!
Example 2: Grab All the Anchors
const allAnchors = document.querySelectorAll('a');
console.log(allAnchors);
// Result: An array of all the <a> tags in the DOM
These anchors won't be sailing away anytime soon!
Example 3: Find All the Invisible Elements
const invisibleElements = document.querySelectorAll(':hidden');
console.log(invisibleElements);
// Result: A secret list of hidden elements
Shh, it's a secret club for invisible elements! You can't see them, but they're there.
Example 4: Hunt Down Aliens
const aliens = document.querySelectorAll('.alien');
console.log(aliens);
// Result: A list of all elements with class 'alien'
We found them! Turns out, aliens are just HTML elements with a peculiar class name.
Example 5: Locate the Quirkiest Elements
const quirkyElements = document.querySelectorAll('.quirky, #mysterious');
console.log(quirkyElements);
// Result: An eclectic mix of quirky and mysterious elements
This collection includes the quirkiest elements in the DOM, including the mysteriously quirky ones.
