HTML DOM attributes Property

Last Updated : 18 Aug, 2026

The attributes property in HTML DOM returns the group of node attributes specified by NamedNodeMap objects. The NamedNodeMap object represents the collection of attribute objects and can be accessed by index number. The index number starts at 0. 

Syntax

node.attributes

Return Value: It returns the NamedNodeMap object which is the collection of nodes. 

Note: In Internet Explorer 8 and earlier versions, the attributes property will return a collection of all possible attributes for an element that can result in higher value than expected.

  • element.attributes gives you a live collection of all the element’s attribute nodes (Attr objects). Because it is a NamedNodeMap (not a regular array), it does not have Array methods such as map(), filter(), or forEach(). You can still iterate it with for...of or access items by index or by name.
  • The order of attributes in the NamedNodeMap is not standardized and can differ between browsers. You should never rely on a specific order when looping through element.attributes. For a more modern and reliable approach when you only need the names, prefer element.getAttributeNames().
