Question

What is the JavaScript code snippet to find all container elements with class “reveal”?

(a) var elements = document.getElementsByClassName(“reveal”);

(b) var elements = document.getElementByClassName(“reveal”);

(c) var elements = document.getElementByName(“reveal”);

(d) var elements = document.getElementsClassName(“reveal”);

I have been asked this question in an online quiz.

This interesting question is from JavaScript in Web Browsers in division Server-Side and Client-Side Scripting of JavaScript

Answer 1

Correct choice is (a) var elements = document.getElementsByClassName(“reveal”);

The best I can explain: The getElementsByClassName() method returns a collection of all elements in the document with the specified class name, as a NodeList object. The above code snippet finds all container elements with class “reveal”.
