public abstract class Attr
extends Node

name

public String name

Returns the name of this attribute. This is a readonly attribute

JavaScript Code Example:

var attr = document.createAttribute('temp');

var output = attr.name;

ownerElement

public Element ownerElement

The Element node this attribute is attached to or null if this attribute is not in use. This is a readonly attribute

Introduced in DOM Level 2

JavaScript Code Example:

var main = document.getElementById('doc');

var attrib = main.getAttributeNode('id');

var output = attrib.ownerElement.nodeName;

specified

public Boolean specified

If this attribute was explicitly given a value in the original document, this is true; otherwise, it is false. Note that the implementation is in charge of this attribute, not the user. If the user changes the value of the attribute (even if it ends up having the same value as the default value) then the specified flag is automatically flipped to true. To re-specify the attribute as the default value from the DTD, the user must delete the attribute. The implementation will then make a new attribute available with specified set to false and the default value (if one exists). In summary:

• If the attribute has an assigned value in the document then specified is true , and the value is the assigned value.
• If the attribute has no assigned value in the document and has a default value in the DTD, then specified is false , and the value is the default value in the DTD.
• If the attribute has no assigned value in the document and has a value of #IMPLIED in the DTD, then the attribute does not appear in the structure model of the document.
• If the ownerElement attribute is null (i.e. because it was just created or was set to null by the various removal and cloning operations) specifiedis true .

This is a readonly attribute.

JavaScript Code Example:

var main = document.getElementById('doc');

var attrib = main.getAttributeNode('id');

var output = attrib.ownerElement.nodeName;

value

public String value

On retrieval, the value of the attribute is returned as a string. Character and general entity references are replaced with their values. See also the method Element.getAttribute(String) on the Element interface.

On the Setting, this creates a Text node with the unparsed contents of the string. I.e. any characters that an XML processor would recognize as markup are instead treated as literal text. See also the method Element.setAttribute(String, String) on the Element interface.

JavaScript Code Example:

var attr = document.createAttribute('temp');

attr.value = 'temporary';

var output = attr.value;
