Javascript objects?

Question

JavaScript

Guys, a question in the studio! ;)

var test = {
  getText: function(some) {

  },
  otherSome: function(someOther) {
    this.getText(); // Не работает
    test.getText(); // Работает
  }
}

Why is that?
PS. And how to implement such a thing ...? The one that doesn't work...

Answer 1

Everything is working.

Answer 2

Why is that?

this refers to the context in which the function was called

test.otherSome(); //контекст - test
test.otherSome.call(null); //контекст - null
new test.otherSome(); //контекст - новый объект унаследованный от test.otherSome.prototype
(0, test.otherSome)(); //контекст - undefined (в strict mode) или глобальный объект (не в strict mode)
({ otherSome: test.otherSome }).otherSome(); //контекст - объект который в скобочках

See the examples above, all except the first one will throw an error that either getText cannot be read from null/undefined (2, 3 examples) or that getText is not a function (3, 5 examples)

Answer 3

this is the function inside which this is called
