NAME

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

SYNOPSIS

  # ...

DESCRIPTION

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.

METHODS

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

DOM Attributes

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

Other Methods

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,
  ;

EXPORTS

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.
