Overview of this book

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. 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. 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. 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. 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.

Binding a collection to a view

In this recipe, we are going to learn how to bind a collection to a view. This can be very helpful if we have different views working with the same collection, or if we want to synchronize data with a REST server.

Let's take an example of the Rendering a model in a view recipe from Chapter 4, Views, where we rendered a collection with subviews and modified it. We are going to add an additional view with the Add and Remove buttons, which will update the collection.

Also, we will bind appropriate callbacks to the model and collection events in our first view, so it is re-rendered automatically when the collection is changed.

When a user clicks on the Add button, he/she is prompted to enter the required information to create InvoiceItemModel.

After the user goes through all the questions, a new model is created and added into a collection, and the corresponding views are updated.

When the Remove button is clicked, the user is promoted to enter the position of the item...
