Chapter 12
Backbone is an extremely popular library for building JavaScript applications, and
this chapter will give you a thorough introduction. We’ll take you through the core
concepts and classes of Backbone, such as models, collections, controllers, and
views. Next, we’ll explore syncing model data with the server using RESTful JSON
queries and how to respond to Backbone appropriately server side. Finally, we’ll
build an example to-do list application that will demonstrate much of the library.
Chapter 13
This chapter explores the JavaScriptMVC library, a popular jQuery-based
framework for building JavaScript web applications. You’ll learn all the basics of
JavaScriptMVC, such as classes, models, and controllers, as well as using client-
side templates to render views. The chapter ends with a practical CRUD list ex-
ample, demonstrating how easy it is to create abstract, reusable, memory-safe
widgets with JavaScriptMVC.
Appendix A
This appendix provides a brief introduction to jQuery, which is useful if you feel
you need to brush up on the library. Most of the book’s examples use jQuery, so
it’s important to be familiar with it. We’ll cover most of the core API, such as
traversing the DOM, manipulating the DOM, and event binding, triggering, and
delegating. Next, we’ll approach jQuery’s Ajax API, making GET and POST JSON
requests. We’ll then cover jQuery extensions and how to use encapsulation to
ensure you’re being a good web citizen. Finally, we’ll take a look at a practical
example: creating a Growl jQuery plug-in.
Appendix B
Appendix B covers Less, a superset of CSS that extends its syntax with variables,
mixins, operations, and nested rules. Less can really reduce the amount of CSS you
need to write—especially when it comes to CSS3 vendor–specific rules. This ap-
pendix covers Less’s major syntax enhancements and how to use the command
line’s tools and JavaScript library to compile Less files down to CSS.
Appendix C
The last appendix is a CSS3 reference. It provides a bit of background on CSS3,
explains vendor prefixes, and then takes you through the major additions to the
specification. Among other CSS3 features, this appendix covers rounded corners,
rgba colors, drop shadows, gradients, transitions, and transformations. It ends with
a discussion about graceful degradation using Modernizr and a practical example
of using the new box-sizing specification.
