我有一个关于子原型的问题.
例如,我想做一些事情:
var Foo = function() { this.Bar.prototype.Foo = this.Baz.prototype.Foo = this };
Foo.prototype.is = "foo";
Foo.prototype.Iam = function() { return this.is };
Foo.prototype.Bar = function() {};
Foo.prototype.Bar.prototype.is = "bar";
Foo.prototype.Bar.prototype.Iam = function() { return this.Foo.is + this.is };
Foo.prototype.Baz = function() {};
Foo.prototype.Baz.prototype.is = "baz";
Foo.prototype.Baz.prototype.Iam = function() { return this.Foo.is + this.is };
var foo = new Foo();
var bar = new foo.Bar();
var baz = new foo.Baz();
console.log(foo.Iam()); // output: foo
console.log(bar.Iam()); // output: foobar
console.log(baz.Iam()); // …
