It's Lenny's Fault

Often times on sites it's useful to automatically have any external link open in a new window. This is a very simple solution that just overrides any link that starts with http:// or https:// and forces them to open in a new window. There are obviously other ways to accomplish this but this is the most simple method. This method consists of a simple jQuery function and forces external links to open in a new window. This is useful for any site with unpredictable content when you know you want external links to open in a new window.

$("a[href^='http://'],a[href^='https://']").click(function(){
    window.open($(this).attr('href'));
    return false;
});

The above code can be problematic if your site uses full urls. For example my site has full urls in the navigation (eg http://itslennysfault.com/about) so with the code above those links would open in a new window. To avoid this use the following code and update "goodDomain" to your site's url.

    $("a[href^='http://'],a[href^='https://']").click(function(){
    	var myHref=$(this).attr('href');
    	var goodDomain="http://itslennysfault.com";
    	if(myHref.toLowerCase().substr(0,goodDomain.length)==goodDomain)
    		return true;
    	window.open(myHref);
    	return false;
    });

Obviously, either code should be placed inside a wrapper and loaded after the DOM is ready.
