Question

I got this code:

var config = {};
config.knock = {
    self:null,
    init : function(){
       self = this;
       console.log(self)
    }
};

$(document).ready( function(){
     config.knock.init();
});

Firefox (8) tells me self is the config.knock object, but Opera (11.00) tells its Window object. Who’s correct?

Answer 1

self ^[MDN] is a property of the window object. It seems that Opera does not allow to override it.

As you are not declaring your variable with var, this

self = this;

is the same as

window.self = this;

in your case.

You either want var self, or, if you want to refer to config.knock.self, either config.knock.self or this.self.

In Firefox as well as in Opera, this will refer to config.knock.
