Attr class

The interface represents one of an element's attributes as an object. In most situations, you will directly retrieve the attribute value as a string (e.g., Element.getAttribute()), but certain functions (e.g., Element.getAttributeNode()) or means of iterating return instances. The core idea of an object of type is the association between a name and a value. An attribute may also be part of a namespace and, in this case, it also has a URI identifying the namespace, and a prefix that is an abbreviation for the namespace. The name is deemed local when it ignores the eventual namespace prefix and deemed qualified when it includes the prefix of the namespace, if any, separated from the local name by a colon (:). We have three cases: an attribute outside of a namespace, an attribute inside a namespace without a prefix defined, an attribute inside a namespace with a prefix:

Attribute Namespace name Namespace prefix Attribute local name Attribute qualified name

myAttr none none myAttr myAttr

myAttr mynamespace none myAttr myAttr

myAttr mynamespace myns myAttr myns:myAttr

Note: This interface represents only attributes present in the tree representation of the Element, being a SVG, an HTML or a MathML element. It doesn't represent the property of an interface associated with such element, such as HTMLTableElement for a <table> element. (See this article for more information about attributes and how they are reflected into properties.)
