rather than a simple link to the prototype. Calling the method should magically
call the corresponding method on the prototype chain. The concept is illustrated in
Listing 7.36.

method
"test super should call method of same name on protoype":
function () {
function Person(name) {
this.name = name;
}
Person.prototype = {
constructor: Person,
getName: function () {
return this.name;
},
speak: function () {
return "Hello";
}
};
function LoudPerson(name) {
Person.call(this, name);
}
LoudPerson.inherit2(Person, {
getName: function () {
return this._super().toUpperCase();
},
speak: function () {
return this._super() + "!!!";
}
});
var np = new LoudPerson("Chris");
assertEquals("CHRIS", np.getName());
assertEquals("Hello!!!", np.speak());
}
In this example we are using
Function.prototype.inherit2
to estab-
lish the prototype chain for the
LoudPerson
objects. It accepts a second argument,
