accessing methods outside the constructor using javascript?

Question

Im trying to access a method outside of the constructor by using this for example:

var Garage = function(location){
    this.someRandomMethod = function(){
      alert("I am a method");
    }

    // car object
    var Car = function(make,model){
      this.model = model;
      this.make  = make;

      var accessRandom = function(){
         this.someRandomMethod(); // the problem!
       }
    }
}

But I am getting function is not defined on the console.

See [How to access the correct `this` / context inside a callback?](http://stackoverflow.com/q/20279484/218196) . However, `Car` should probably not be defined inside `Garage` anyway. — Felix Kling, Jan 04 '15 at 20:13

The this is referring to the Car, not the Garage. Try assigning the outer this to a variable:

var Garage = function(location){
    this.someRandomMethod = function(){
      alert("I am a method");
    }

    var garage = this;

    // car object
    var Car = function(make,model){
      this.model = model;
      this.make  = make;

      var accessRandom = function(){
         garage.someRandomMethod();
       }
    }
}

*"The `this` is referring to the `Car`"* I assume you mean instance of `Car` (not the function `Car`), but even then, we don't know that. We don't know how `accessRandom` is called. – Felix Kling Jan 04 '15 at 20:14
