var node = element.getAttributeNode('href');


The example above gets a reference to the href Attr node of an element, then removes it.

So if the element in that example referred to this HTML:

<a href="" rel="me">brothercake</a>

Then the operation would result in this:

<a rel="me">brothercake</a>


attr (Attr) required

The attribute node to remove.


Remove a specified attribute node (a reference to which can be retrieved with getAttributeNode or getAttributeNodeNS). This method is essentially the same as removeAttribute, except that its argument is the attribute node itself, rather than the attribute's name.

If the attribute has a specific default value in this document type, a new node should be created with the default value (and the same namespaceURI, localName and prefix if applicable).

Note: There is no removeAttributeNodeNS

Unlike all the other attribute methods, there is no namespaced equivalent for this one — no method called removeAttributeNodeNS is defined by the DOM1

In Internet Explorer 5.5 in HTML this method is not implemented (it returns undefined).

In Internet Explorer, Firefox, Safari and Opera 9.5 when removing an attribute which has a specific default value in this document type, the attribute is not replaced with the default (only Opera 9.0 gets this right).

In Internet Explorer 6 and 7 in HTML this method does not remove attribute nodes, it merely resets them, according to what type of value IE considers the attribute to have. For an attribute node that IE considers to be boolean true (such as disabled, when defined) the value is reset to false; on a value it considers to be a a number (such as tabindex) the value is reset to zero; on a value it considers to be a function (event-handling attributes such as onclick) the value is reset to null; on a style attribute this method has no effect; for all other (string-type) attributes the value is reset to an empty string.


1 The DOM considers that a removeAttributeNodeNS method is not required; this is noted in the DOM FAQ.
