- The Attr node to add to the attribute list.
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.
Adds a new attribute node. If an attribute with that name (
nodeName) is already present in the element, it is
replaced by the new one. Replacing an attribute node by itself has no
effect.
To add a new attribute node with a qualified name and namespace
URI, use the setAttributeNodeNS method.
