blech75 / external_script_domains.js

Created September 3, 2010 20:12

a little Prototype.js magic for returning the domains of external JS files

	$A(document.getElementsByTagName('SCRIPT')).reject(function(s){
	return !s.getAttribute('src');
	}).map(function(s){
	return s.getAttribute('src');
	}).reject(function(u){
	return u.charAt(0) == "/";
	}).map(function(u){
	return /^https?:\/\/([^/]+)/i.exec(u)[1];
	}).uniq();
