Override function in JavaScript

javascript, prototype

Solution

Since you are correctly overriding the function on the object itself and not on its prototype, you can still call the prototype function with your object.

reader.getName = function() {
    var baseName = Person.prototype.getName.call(this);
    ...
}

Problem

Possible Duplicate: Calling base method using JavaScript prototype I want to inheritance object that will override function in javascript. From the method I want to call to the base method. In this case I inherit object `reader` from `Person` and now I want to override the function `getName` meaning that in reader first I want to call the function on `Person` and then to do some changes. ``` <script> /* Class Person. */ function Person(name) { this.name = name; } Person.prototype.getName = function() { return this.name; } var reader = new Person('John Smith'); reader.getName = function() { // call to base function of Person, is it possible? return('Hello reader'); } alert(reader.getName()); </script> ```
