object Key in javascript class/dictionary?

I have a Javascipt object which I use as dictionary

var obj={

           xxx:'1'

           yyy:'2'

        }

However - xxx and yyy should be a jQuery object .

something like :

var obj =

          { 

             $('#div1'):'1' , 

             $('#div2'):'2'

           }

is it possible ?

also, How can I get the " value " for key $('#div2') ?

p.s. I the $.data cant help me here since its also a key value and i need in the key - object Type also.
