Acess To This From Subobject In JavaScript

How do I get access to the properties or method of the main object, from sub-obiect level two (sub3). If possible I would like to avoid solutions chaining return this. Obj = functi

Solution 1:

With your current syntax, you can't. Because for sub2 and sub3, the this variable is Obj.prototype.subobject.

You have multiple choice:

• The obvious one: don't use a suboject.

• Create subobject, sub2 and sub3 in the constructor

  Obj = function() {
      var self = this;
  
      this.subobject = {
          sub1: function() { console.log(self); }
      }
  }
  

• Use bind at each call:

  o.subobject.sub2.bind(o)();
