Remove attribute?

[JohnSaunders]

Can someone tell me how to remove an attribute from an element that is dynamically assigned using Javascript? (such as a CSS class)

[hamstu]

obj.removeAttribute(attrName);

(such as a CSS class)

But what if an element belongs to more than one class?

You might want to consider alternatives for removing a class name from an element's class attribute.
