The sessionStorageproperty allows you to access a session Storage object for the current origin.It is two way process first of all stringifyobject before storing to session and second parseto getting back .

     var user = {'name':'John'};
     sessionStorage['user'] = JSON.stringify(user);
     console.log(sessionStorage['user']);
     var obj = JSON.parse(sessionStorage['user']);
     console.log(Object.keys(obj).length);

Here is fiddle.Opening a page in a new tab or window will cause a new session to be initiated. More About session storage.
