Question

Lets say I have a namespace called ns and ns has to functions on it:

ns = {};
ns.Foo = function(message, fn){
    this.message = message;
    fn.call(this);
};
ns.bar = function() {
    alert('Hello, world!');
};

And I call it like this:

var foo = new Foo('My Message', function() {
    bar();
});

I get an error saying bar() is undefined. But if I call it this way:

var foo = new Foo('My Message', function() {
    this.bar();
});

It works. Is there a way to structure my JavaScript so I can just call bar() without the this?

Thanks!

No. JavaScript is not Java. You need to specify object whose method you’re calling.
