Question

Quick question about JSON in general, say I had:

var foo = {
  a: null,
  init: function() {
    this.a = document.getElementById(...);
  }
}

This will give have a with null. Is there anyway to go outside this scope and get the document element other than doing it externally via foo.a = document.getElementById(…)?

EDIT: Changed title more appropriately.

I am calling foo.init(), but when I do this, say I have:

and then I call init.foo() which contains this.a = document.getElementById(‘test’) it seems to return NULL, perhaps I am doing something wrong.

Answer 1

This works fine:

var foo = {
  a: null,
  init: function() {
    this.a = document.getElementById('test');
  }
}

foo.init();
console.log(foo.a);
