How to check if a DOM element has a class

By Flavio Copes

Learn how to check if a DOM element has a class using the contains method of the classList object, which implements the DOMTokenList interface.

~~~

Use the contains method provided by the classList object, which is:

element.classList.contains('myclass')

Technically, classList is an object that satisfies the DOMTokenList interface, which means it implements its methods and properties.

You can see its details on the DOMTokenList MDN page.
