Add target blank and track in Google Analytics to outgoing links

gistfile1.js

// Add target blank and track outgoing links in Google Analytics

// Method 1 (recommended): Event delegation. Track as Event.
// 'click'
// element and class names (i.e. a.button)
// href value clicked
$('body').on('click', function( e ) {
	var target = $(e.target);
	if ( target.tag == 'A' )
	{
		_gaq.push([
			'_trackEvent',
			'click',
			target.tagName + '.' + target.className.replace( ' ', '.' ),
			target.getAttribute('href')
		]);
	}
});

// Method 2a: Inline. Track as Event
$("a").attr('onclick', "javascript:_gaq.push(['_trackEvent', 'Click', $(this).tag+'.'+$(this).className.replace(' ', '.'), $(this).getAttribute('href')]);");

// Method 1b: Inline. Track as Pageview
$("a[href^='http:']").not("[href*='"+document.domain+"']").attr('target','_blank').attr('onclick', "javascript:_gaq.push(['_trackPageview', '/external/'+$(this).attr('href')]);");

// Method 3: Event based (worse performance)
$("a").on('click', function() {
	a = attr('href');
	if (a.match(/:\/\//)) && a.indexOf(document.domain) !== -1) {
		$(this).attr('target', '_blank');
		_gaq.push(['_trackPageview', '/external/'+$(this).attr('href')]);
	}
});
