Is there a shorter/more efficient way of writing this expression?
===

I have a `nav` with some child `a`-elements. I added a click function to those elements, and want to know, which one was clicked. As there can be a `span` inside (but don't have to) the `a`-tag as well I used this code to get the index:

### HTML ###

	<nav>
		<a href=""><span></span>Link text</a>
		<a href=""><span></span>Link text</a>
	</nav>

### JavaScript ###
	var items = $('nav > a');
	
	items.click( function(event) {
		
		var target	= ( $(event.target).is('span') ? $(event.target).parent() : $(event.target) ); 
		var key		= items.index( target );
		
		console.log( key );
		
		event.preventDefault();
	});

So my question is: Is there a better/short/faster way of writing this?
