How to Restore form using Cookie

How to Restore form using Cookie

I am using js cookie plugin to generate json cookie.
  1. Cookies.set('myTestCookie', { cookieData },{ expires: 30 });
I am also able to restive it.
  1. var $recivedCookieData= Cookies.get('myTestCookie');
  2. alert($recivedCookieData);
   I am also getting alert as
  1. {"cookieData":{"country":"uk","state":"england","city":"london","location":"Baker Street", "zip":"W1U"}}
if I have to fill up the form using the cookie data how should I do it?
my form uses post method.

Thank You.
