Definition and Usage
The removeAttributeNode() method removes the specified attribute from an element, and returns the removed attribute, as an Attr Node object.
The difference between this method and the removeAttribute() method, is that the removeAttribute() method removes the attribute with the specified name, while this method removes the specified Attr object. The result will be the same. Also, the removeAttribute() method has no return value, while this method returns the removed attribute, as an Attr object.
Tip: Use the getAttributeNode() method to return an attribute node of an element.
Tip: Use the setAttributeNode() method to add an attribute node to an element.
