Is it possible to get an object of an object if I have a reference to a property?

Question

I have a reference to an object property in a variable, is it possible to access the object to which this property belongs?

Answer 1

var obj = { p1: 1, p2: function(){ return this; }, p3: obj, p4: function() { return obj; } } // v1 is now integer, we cannot get actual `obj` from this `v1` var v1 = obj.p1; // `v2()` returns `window` object (or current context object), // so if `obj` is created only in global context (or current // context which you're calling `v2()`), you can get reference to `obj` var v2 = obj.p2; // as @Ignacio mentioned, you can use `v3` as reference to `obj` var v3 = obj.p3; // `v4()` also reference to `obj` var v4 = obj.p4; 

Answer 2

Unless the property value contains an object reference.
