Access parent's parent from javascript object

Something like

var life= {
        users : {
             guys : function(){ this.SOMETHING.mameAndDestroy(this.girls); },
             girls : function(){ this.SOMETHING.kiss(this.boys); },
        },
        mameAndDestroy : function(group){ },
        kiss : function(group){ }
};

this.SOMETHING is what I imagine the format is, but it might not be. What will step back up to the parent of an object?

I simply added in first function

parentThis = this;

and use parentThis in subfunction. Why? Because in JavaScript, objects are soft. A new member can be added to a soft object by simple assignment (not like ie. Java where classical objects are hard. The only way to add a new member to a hard object is to create a new class) More on this here: http://www.crockford.com/javascript/inheritance.html

And also at the end you don't have to kill or destroy the object. Why I found here: http://bytes.com/topic/javascript/answers/152552-javascript-destroy-object

Hope this helps

JavaScript does not offer this functionality natively. And I doubt you could even create this type of functionality. For example:

var Bobby = {name: "Bobby"};
var Dad = {name: "Dad", children: [ Bobby ]};
var Mom = {name: "Mom", children: [ Bobby ]};

Who does Bobby belong to?

In this case, you could use life to reference the parent object. Or you could store a reference to life in the users object. There can't be a fixed parent available to you in the language, because users is just a reference to an object, and there could be other references...

var death = { residents : life.users };
life.users.smallFurryCreaturesFromAlphaCentauri = { exist : function() {} };
// death.residents.smallFurryCreaturesFromAlphaCentauri now exists
//  - because life.users references the same object as death.residents!

You might find it helpful to use something like this:

function addChild(ob, childName, childOb)
{
   ob[childName] = childOb;
   childOb.parent = ob;
}

var life= {
        mameAndDestroy : function(group){ },
        kiss : function(group){ }
};

addChild(life, 'users', {
   guys : function(){ this.parent.mameAndDestroy(this.girls); },
   girls : function(){ this.parent.kiss(this.boys); },
   });

// life.users.parent now exists and points to life
