• 2 If the code works as intended, it's better asked on Code Review. – Jongware Commented Oct 27, 2014 at 8:36
• @Sergey -- just be careful with recursive functions, they are limited depending the browser you use. In fact wouldnt it be better to just send that list server side to handle it with PhP? – kockburn Commented Oct 27, 2014 at 8:38
