[object MutationEvent]

This feature has been removed from the Web. Though some browsers may still support it, it is in the process of being dropped. Do not use it in old or new projects. Pages or Web apps using it may break at any time.
  • IE prior to version 9 didn't support the mutation events at all and does not implement some of them correctly in version 9 (Žfor example, DOMNodeInserted)
  • WebKit doesn't support DOMAttrModified (see Žwebkit bug 8191 and Žthe workaround)
  • "mutation name events", i.e. DOMElementNameChanged and DOMAttributeNameChanged are not supported in Firefox (as of version 11), and probably in other browsers as well.
