Question

How can I do inheritance with this example.

I’m trying to create an object literal that functions as a singleton. Within this I’d like to extract my classes. Next to that, these classes should inherit from each other when applicable.

Like so:

var Singleton = {

    car: function() {
        this.engine= true;
    },

    ford: function() {
        this.color = 'red';
    }
};

I’d like to let ford inherit from bar, but I can’t do this:

    ford: function() {
        this.color = 'red';
        this.prototype = new this.car();
    }

Any ideas?

Answer 1

var Something = {

    foo: function() {
        this.greet = 'hello';
    },
    bar: function() {
        this.color = 'blue';
    }
};

Something.bar.prototype = new Something.foo();
alert((new Something.bar()).greet)

Here is a primer on inheritance
