I recently came upon an interesting jQuery article about how you can retrieve all external links within a page, build the address of the site’s favorite icon, and place the favorite icon along side the link. I’ve chosen a different approach which uses CSS to position the favorite icon as a background image.

The CSS

.favicon	{ background-repeat:no-repeat; padding:2px 0 3px 22px; }

This CSS code will provide padding and background image placement for the link.

The MooTools Javascript

/* when the dom is ready... */
window.addEvent('domready',function() {
	/* grab all complete linked anchors */
	$$('a[href^="http://"]').each(function(a) {
		/* if it's not on the davidwalsh.name domain */
		if(!a.get('href').contains(window.location.host)) {
			/* get the favicon */
			var favicon = a.get('href').replace(/^(http:\/\/[^\/]+).*$/, '$1') + '/favicon.ico';
			/* place it in the anchor */
			a.setStyle('background-image','url(' + favicon + ')').addClass('favicon');
		}
	});
});

I’ve chosen to include the favorite icon as a background image as opposed to the jQuery article’s method of injecting an image.

Would you use this method on your website?
