jQuery Delegate - Find Delegate Object Inside Event Closure

How can I access a delegated object inside a delegate event handler? Hopefully an example should clarify my vague question.

$parent.delegate('a.some_class', 'click', someHandler);

function someHandler(e) {
  //how do I find $parent here?
}

This is partly down to how I've structured my particular .js file, where declarations are separate from implementation (yeah, old skool I know).

In someHandler, e.target and $(this) refer to the a.some_class object. Does e also have a reference to $parent? If not, what is the recommended way of finding the $parent?

Thanks for any help.

Jens Roland is correct. To add, the e.currentTarget should have given you the $parent where the event is actually handled. There's a bug that explains why currentTarget is not working the way it's supposed to http://bugs.jquery.com/ticket/11756

UPDATE: There is a way to grab the original element - e.originalEvent.currentTarget:

$parent.delegate('a.some_class', 'click', someHandler);

function someHandler(e) {
  var originalParent = $(e.originalEvent.currentTarget);
}

Original answer:

I'd probably do it like this:

$parent.delegate('a.some_class', 'click', someHandler);
function someHandler(e) {
  var parent = $(this).parent();

  // Or if $parent isn't the immediate ancestor of the links:
  var parent = $(this).closest('.parentClass');
}

Stupid me. Should have read the jQuery docs better.

This should do it:

$parent.delegate('a.some_class', 'click', $parent, someHandler);

function someHandler(e) {
  var parent = e.data;
}

e.data (in SomeHandler) always points to eventData, if using this delegate call.

.delegate( selector, eventType, eventData, handler )

Hope this helps someone.
