Overview of this book

<p>There is no doubt that the superior rendering power of HTML5, thin-to-thick client transition and REST style communication created a new era in web development, replacing the outdated approach based on browser plugin technologies. Backbone.js allows developers to write lightweight, modular, and scalable JavaScript applications.<br /><br />Backbone.js Cookbook contains a series of recipes that provide practical, step-by-step solutions to the problems that may occur during frontend application development using an MVC pattern. You will learn how to build Backbone applications utilizing the power of popular Backbone extensions and integrating your app with different third party libraries. You will also learn how to fulfill the requirements of the most challenging tasks.<br /><br />The first chapter of the book introduces you to the MVC paradigm and teaches you how to architect rich Internet applications operating with basic concepts of Backbone.js. During the reading of this book you will learn how to solve challenging problems leveraging Backbone objects such as models, collections, views, routers, and so on.</p> <p><br />You learn how to use forms, layouts, templating engines, and other Backbone extensions, which will help you to complete specific features of your application. You will understand how to bind a model to a DOM element. You will see how perfectly Backbone.js integrates with third party libraries and frameworks such as jQuery, Zepto, Underscore.js, Require.js, Mustache.js, Twitter Bootstrap, jQueryMobile, PhoneGap and many others. This book will guide you in how to optimize and test your applications, create your own Backbone extensions, and share them with the open source community.</p> <p><br />With the help of Backbone.js Cookbook, you will learn everything you need to know to create outstanding rich Internet applications using the JavaScript programming language.</p>

Creating undo points to store/restore a model's state


Sometimes, you may need to manage the states of a model in your application. This can be useful in one of the following cases:

  • Your application requires an undo/redo feature

  • You want to implement transactions

  • Your application emulates some process

  • You want to change a model temporarily and then restore it

Typically for all of the previous cases developers often use the Memento pattern. There is an implementation of this pattern in Backbone, which is available in the Backbone.Memento extension. This extension allows developers to store or restore a model's state and provides a stack for operating with multiple states.

Getting ready

You can download the Backbone.Memento extension from the GitHub page https://github.com/derickbailey/backbone.memento. To include this extension into your project, save the backbone.memento.js file into the lib folder and include a reference to it in index.html.

Note

Including a Backbone extension into your project is...
