queryselectorAll - find an element with more than one matching class

Question

Using the JS queryselectorall method is it possible to select an elemnent of a particular tag name with 2 matching classes.

E.g. I have an element

<a class="classOne classTwo"></a>

using queryselectorall I can select on one classname:

document.querySelectorAll("a.classOne");

how could this be extended so I can find all a tags with classOne AND classTwo?

document.querySelectorAll("a.classOne classTwo"); as expected doesn't seem to work

Thanks in advance

Answer 1

The same way you would in CSS:

document.querySelectorAll("a.classOne.classTwo");

Answer 2

Just add a dot..

document.querySelectorAll("a.classOne.classTwo")
