XUL:Events - MDC
DOMAttrModified
Fired after an Attr has been modified on a node. The target of this event is the Node whose Attr changed. The value of attrChange indicates whether the Attr was modified, added, or removed. The value of relatedNode indicates the Attr node whose value has been affected. It is expected that string based replacement of an Attr value will be viewed as a modification of the Attr since its identity does not change. Subsequently replacement of the Attr node with a different Attr node is viewed as the removal of the first Attr node and the addition of the second.
