► Inheritance of Properties and Methods through the Prototype Object Chain Server-Side and Client-Side Web Scripting The output can also be represented with this diagram:ĮCMAScript Language Specification and JavaScript DialectsĬreating, Accessing, and Manipulating Arrays The output of this tutorial example confirms what we learned earlier: ShowObject(Book.prototype, 'Book.prototype') ĭocument.writeln('\n\''+name+'\' properties:') ĭocument.writeln(' '+item+': '+object) Showing the object, constructor, and prototype Var myBook = new Book('JavaScript Tutorials', 'Herong Yang') To inherit the 'price' property from the constructor's prototype object: To demonstrate those rules, I wrote the following tutorial example to allow 'myBook' Each object will inherit properties and methods from its constructor's prototype object.Properties and methods can be added to the constructor's prototype object.The constructor's 'prototype' is an object.
A tutorial example and diagram is provided to show relations of an object, its constructor, and the constructor's prototype object.įrom previous chapters in this book, we learned that: This section provides a quick description of how object inheriting properties and methods from its constructor's prototype object.
