Today, jQuery is used by over half of the 10,000 most-visited web sites, and jQuery is one of the technologies that every web developer should master. The trouble is that jQuery is difficult to learn, especially for programming novices. Now, this new book makes it easier than ever to learn jQuery, jQuery UI (User Interface), and jQuery Mobile. In essence, sections 2 and 3 of this book present all of the jQuery and jQuery UI skills that you need for developing professional jQuery applications. With those skills, you will be able to add all of the popular jQuery applications to your web pages: image swaps, image rollovers, collapsible panels, slide shows, accordions, tabs, carousels, and more. Beyond that, though, you will have all the skills that you need for developing unique jQuery applications of your own. But that's just two of the five sections in the book. Because you need to know JavaScript in order to use jQuery, section 1 presents the least you need to know about JavaScript to get the most from jQuery. This is essential for programming novices, but this is also valuable for experienced programmers who may not remember how a specific JavaScript statement or method works. In short, this section makes this book a complete reference for jQuery programmers. In contrast, section 4 takes jQuery to a new level by showing you how to use Ajax and JSON to get data from a web server and add it to a web page without reloading the page. It also shows how to use Ajax and JSON with the APIs for popular web sites like Blogger, YouTube, Twitter, Flickr, and Google Maps. These are powerful skills for enhancing a web site. To complete this package, section 5 presents a complete course in jQuery Mobile, which offers an exciting, new way to develop web sites for mobile devices. Today, the best web sites are available in both full and mobile versions, so this section also shows how to use a JavaScript plugin to redirect a mobile device from the full version of a web site to its mobile version.

Ruby is the fastest growing and most exciting dynamic language out there. If you need to get working programs delivered fast, you should add Ruby to your toolbox. This book is the only complete reference for both Ruby 1.9 and Ruby 2.0, the very latest version of Ruby. 2013 marks the 20th anniversary of the Ruby language. We're proud that throughout its history, we've continued to cover the latest version of Ruby. Would you like to go from first idea to working code much, much faster? Do you currently spend more time satisfying the compiler instead of your clients or end users? Are you frustrated with demanding languages that seem to get in your way, instead of getting the work done? Are you using Rails, and want to dig deeper into the underlying Ruby language? If so, then we've got a language and book for you! Ruby is a fully object-oriented language, much like the classic object-oriented language, Smalltalk. Like Smalltalk, it is dynamically typed (as opposed to Java or C++), but unlike Smalltalk, Ruby features the same conveniences found in modern scripting languages such as Perl and Python. The combination of the power of a pure object-oriented language with the convenience of a scripting language makes Ruby a favorite tool of intelligent, forward-thinking programmers. The Pickaxe contains four major sections: * An acclaimed tutorial on using Ruby. * The definitive reference to the language. * Complete documentation of all built-in classes, modules, and methods. * Complete descriptions of all 97 standard libraries. This is the reference manual for Ruby, including a description of all the standard library modules, a complete reference to all built-in classes and modules (including all the new and changed methods introduced by Ruby 1.9, 1.9.2, 1.9.3, and 2.0). It also includes all the new and changed syntax and semantics introduced since Ruby 1.8. Learn about the new parameter passing rules, local variable scoping in blocks, fibers, and the new block declaration syntax, among other exciting new features. About Ruby 2.0 Ruby 2.0 is a minor update to Ruby 1.9, unlike the more major updates from Ruby 1.8 to Ruby 1.9. The major language changes in Ruby 2.0 are the addition of keyword arguments and the change to use UTF-8 as the default source file encoding. There are a number of additions to the standard library, including: * @Enumerator::Lazy@, which adds support for lazy access to potentially infinite lists. * Refinements allow you to encapsulate changes to third-party classes, and scope their application to individual source files, preventing your changes from polluting the global application. You'll also find that Ruby 2 is faster, and has memory management improvements that make it more server-friendly. All told, there are over 110 sections of the book that have been flagged and cross-linked to indicate 2.0 content. What You Need * This book assumes you have a basic understanding of object-oriented programming. * In general, Ruby programmers tend to favor the the command line for running their code, and they tend to use text editors rather than IDEs.

One of the most useful features of today's modern browsers is the ability to store data right on the user's computer or mobile device. Even as more people move toward the cloud, client-side storage can still save web developers a lot of time and money, if you do it right. This hands-on guide demonstrates several storage APIs in action. You'll learn how and when to use them, their plusses and minuses, and steps for implementing one or more of them in your application. Ideal for experienced web developers familiar with JavaScript, this book also introduces several open source libraries that make storage APIs easier to work with. Learn how different browsers support each client-side storage API Work with web (aka local) storage for simple things like lists or preferences Use IndexedDB to store nearly anything you want on the user's browser Learn how support web apps that still use the discontinued Web SQL Database API Explore Lockr, Dexie, and localForage, three libraries that simplify the use of storage APIs Build a simple working application that makes use of several storage techniques

Learn how to advance your skill level of Haskell, and use this language for practical web development. This book uses a direct, no nonsense approach, so you no longer need to spend extra time reading the documentation, blog posts, and forums to understand how to use Haskell - all that knowledge is provided in one coherent resource. You'll start by reviewing how multiple facets of web development are done in Haskell, such as routing, building HTMLs, interacting with databases, caches, and queues, etc. You'll then move on to using notable libraries, such as "scotty" for routings, "digestive-functor" for input validation, and "postgresql-simple" for interacting with databases. In the later chapters, you'll learn how all of these libraries can be used together by working on a fully functioning project deployed on Heroku. What You'll Learn Set up a productive Haskell development environment Review basic tasks that are encountered when building web applications. Explore how to interact with external systems, such as databases, queues, and RESTful APIs. Build a RESTful API, website, building views and form validation. Who This Book Is For Software developers familiar Haskell and would like to apply the knowledge on real world applications and software developers new to Haskell.

Learn and master the new features in the new Eclipse Jakarta Faces (formerly JavaServer Faces or JSF) web framework in this definitive guide written by two of the driving forces of the Faces project and the co-creators of the OmniFaces library. Authors Bauke Scholtz and Arjan Tijms take you through real-world examples that demonstrate how these new features are used with other APIs in Jakarta EE. You'll see the new and exciting ways Jakarta Faces applications can use to communicate between a client and a server, such as using WebSockets, invoking bean methods directly from Ajax, executing client-side JavaScript when Ajax calls complete, and more Along the way you'll broaden your knowledge of Faces components and web APIs best practices, and learn a great deal about the internals of Faces and the design decisions that have been made when building the Faces API. For example, you'll see what artefacts are now CDI injectable, how CDI changed Faces internally, and what some of the caveats are when working with the CDI versions of a Faces artefact. Furthermore, you'll build an example application from scratch. After reading The Definitive Guide to Jakarta Faces in Jakarta EE 10, you'll be ready to build your own efficient and secure web applications. What You Will Learn Leverage the new features in Jakarta Faces in Jakarta EE in your existing applications Integrate Faces and CDI Use the brand new Component Search Expression framework, which enables you to more easily locate components from your template Extend the Component Search Expression framework with your own search operators Work with the different ways of mapping requests to Faces, make your application use extension-less URLs, and programmatically inspect which resources are present in your application Master the best practices for web application development and see which are obsolete Who This Book Is For Existing JSF or Java developers who need to create a web UI. No prior knowledge of Faces is required, but the book does skew towards the more experienced developer. Concepts such as dependency injection and MVC are assumed to be known, as is a general knowledge about HTML, HTTP and other web standards.
