HTML::DOM::Event::Mutation - A Perl class for HTML DOM mutation event objects

  # ...

This class provides MutationEvent objects for HTML::DOM, which objects are passed to event handlers for certain event types when they are invoked. It inherits from HTML::DOM::Event.

See also those inherited from HTML::DOM::Event.

These are all read-only and ignore their arguments.

relatedNode

This holds the parent node for DOMNodeInserted and DOMNodeRemoved events, and the Attr node involved for a DOMAttrModified event.

prevValue

The previous value for DOMAttrModified and DOMCharacterDataModified events.

newValue

The new value for the same two event types.

attrName

The name of the affected attribute for DOMAttrModified events.

attrChange

initMutationEvent ( $name, $propagates_up, $cancellable, $rel_node, $prev_value, $new_value, $attr_name, $attr_change_type )

This initialises the event object. See initEvent in HTML::DOM::Event for more detail.

init ( ... )

Alternative to initMutationEvent that's easier to use:

  init $event
      type => $type,
      propagates_up => 1,
      cancellable => 1,
      rel_node => $node,
      new_value => $foo,
      prev_value => $bar,
      attr_name => $name,
      attr_change_type => HTML::DOM::Event::Mutation::REMOVAL,
  ;

The following constants are exported upon request, either individually or with the ':all' tag. They indicated the type of change that a DOMAttrModified event represents.

• ADDITION
• MODIFICATION
• REMOVAL
