read cookie value in jquery

I have called one php page inside the iframe

I have stored some values in cookies.I want to read that cookies values from that page to other page.

I used jQuery to read cookie.

var value = $.cookie('artname');

'artname' is the cookie name.

But it displaying null value because cookies path is different,path is "/v/abcfile/frontend/".

But the path for the other cookies on the page i am trying to get is "/.

I tried with this: top.jQuery.cookie('artname'); Its still showing me the same.

how can I get value of cookie?
