How to remove class attribute from div?

Question

I am using JavaScript and I want to add/remove a Class attribute if a button is clicked. I am able to add the class, but I don\'t know how to remove it. how can I do that?

Answer 1

The nicest way to set classes with Javascript is to use the className property:

// to add
box.className = 'move';
// to remove
box.className = '';
