function ThingSayFoo() { alert('foo! ' + this + this.location); }
function Thing() { this.location = 'thing'; return this; }
Thing.prototype = { sayFoo: ThingSayFoo }
function Amajig() { this.location = '-a-ma-jig'; return this; }
Amajig.prototype = { sayFoo: ThingSayFoo }
// Called directly, this is the brwoser window, closures at work.
ThingSayFoo()
// Thing is this.
new Thing().sayFoo();
// Amajig is this.
new Amajig().sayFoo();
Didn't see the orginal code, but a refernece to this is not lost. It
is added. And it is added based on how the function is called.
Bind keeps the desired target object in a closure, and calls the
member function "though" the object. Assigning the method directly
means it is called directly.
Cheers.
