The attr() method sets or returns attributes and values of the selected elements.

When this method is used to return the attribute value, it returns the value of the FIRST matched element.

In case you want to return the attribute value of all matched elements, you must use iterate() together. See start.md for more information.

When this method is used to set attribute values, it sets one or more attribute/value pairs for the set of matched elements.

The removeAttr() method removes one or more attributes from the selected elements.
