Documentation for this section has not yet been entered.
Type Reason Org.W3c.Dom.DOMException WRONG_DOCUMENT_ERR: Raised if newAttr was created from a different document than the one that created the element.
NO_MODIFICATION_ALLOWED_ERR: Raised if this node is readonly.
INUSE_ATTRIBUTE_ERR: Raised if newAttr is already an attribute of another Element object. The DOM user must explicitly clone Attr nodes to re-use them in other elements.
NOT_SUPPORTED_ERR: May be raised if the implementation does not support the feature "XML" and the language exposed through the Document does not support XML Namespaces (such as []).
Adds a new attribute. If an attribute with that local name and that
namespace URI is already present in the element, it is replaced by
the new one. Replacing an attribute node by itself has no effect.
Per []
, applications must use the value null as the
namespaceURI parameter for methods if they wish to have
no namespace.
