Assign object function preserving "this"

Hi,

I would like to know if this is possible in some way?

var $object1 = {
$id : 1,
test : function()
{
alert(this.$id);
}
};

var $object2 = new function()
{
this.$id = 2;
this.test = function()
{
alert(this.$id);
};
//ASSIGN OBJECT1 WITH THIS INTERNAL FUNCTION
$object1.test = this.test;
};

$object1.test();
$object2.test();

The result I was must be that both $object1 and $object2 alert with the number 2.

Thanks!
