I just tell jQuery what I want, and it works around the implementation differences for me • jQuery is open source When I don’t understand how something works or I don’t quite get the result I expect, I can read through the JavaScript code and, if needed, make changes The genius of jQuery is that it takes something that is a major grind in web development and makes it simple, quicker, and easier I can’t ask for more than that Not everything is perfect, of course, and there are one or two rough edges, which I’ll explain as I get into the details But even with the occasional flaw, I love working with jQuery, and I hope you will find it equally compelling and enjoyable to use Understanding jQuery UI and jQuery Mobile In addition to the core jQuery library, I also cover jQuery UI and jQuery Mobile, which are user interface (UI) libraries built on top of jQuery jQuery UI is a general-purpose UI toolkit intended to be used on any device, and jQuery Mobile is designed for use with touch-enabled devices such as smartphones and tablets Understanding jQuery Plug-ins jQuery plug-ins extend the functionality of the basic library Some plug-ins are so good and so widely used that I have covered them in this book There are a lot of plug-ins available (although the quality can vary), so if you don’t like the plug-ins I describe in this book, you can be confident that an alternative approach is available Chapter ■ Putting jQuery in Context What Do I Need to Know? Before reading this book, you should be familiar with the basics of web development, have an understanding of how HTML and CSS (cascading style sheets) work, and, ideally, have a working knowledge of JavaScript If you are a little hazy on some of these details, I provide refreshers for HTML, CSS, and JavaScript in Chapters 2, 3, and You won’t find a comprehensive reference for HTML elements and CSS properties, though There just isn’t the space in a book about jQuery to cover HTML in its entirety If you want a complete reference for HTML and CSS, then I suggest another of my books: The Definitive Guide to HTML5, also published by Apress What Is the Structure of This Book? This book is split into six parts, each of which covers a set of related topics Part 1: Getting Ready Part of this book provides the information you need to get ready for the rest of the book It includes this chapter and primers/refreshers for HTML, CSS, and JavaScript Later in this chapter, I’ll describe the software that you will need in order to follow along Part 2: Working with jQuery Part of this book introduces you to the jQuery library, starting with a basic example and building up to include each of the core features: element selection, DOM manipulation, events, and effects Part 3: Working with Data and Ajax Part of this book shows how jQuery makes it possible to work with inline or remote data I show you how you can generate HTML content from data, how you can validate data entered into web forms, and how you can use jQuery to perform asynchronous operations, including Ajax Part 4: Using jQuery UI jQuery UI is one of the two user interface libraries that I describe in this book Built on, and integrated with, the core jQuery library, jQuery UI allows you to create rich and responsive interfaces for your web applications Part 5: Using jQuery Mobile jQuery Mobile is the other user interface library that I cover in this book jQuery Mobile is built on top of jQuery and incorporates some basic feature from jQuery UI but has been optimized for creating smartphone and tablet interfaces Fewer UI widgets are available in jQuery Mobile, but those that are supported are optimized for touch interaction and for presentation on smaller displays Part 6: Advanced Features The final part of this book describes some jQuery and jQuery UI features not commonly used but which can be helpful in complex projects These are advanced features that require a better understanding of HTML, CSS, and jQuery itself When reading Chapter 36, a basic knowledge of asynchronous programming is very helpful Chapter ■ Putting jQuery in Context What’s New in This Edition? Since the first edition of this book, jQuery, jQuery UI, and jQuery Mobile have all undergone substantial changes What’s New for Core jQuery? The API for the core jQuery library is remarkably stable Some years ago, the jQuery team starting listing changes that they intended to make, and these were implemented with the release of jQuery version 1.9 Some of these changes are quite substantial and I have indicated the changes in each chapter throughout Part of this book The good news is that these changes are very rare and the API is likely to remain stable for several years That’s not to say that new features won’t be added, but the code that you develop today will continue to work without modification for some time to come The bad news is that the jQuery team did something unusual when they released jQuery 1.9—they also released jQuery 2.0, and thus they split development into two lines of parallel releases: jQuery 1.x and jQuery 2.x Both release lines have the same API but jQuery 2.x doesn’t support versions 6, 7, and of IE The older versions of IE are notorious in their non-standard approach to HTML, CSS, and JavaScript, and removing all of the checks for odd behavior and the associated workarounds makes jQuery 2.x smaller and faster ■■Tip At the time of this writing, the current versions of jQuery are 2.0.2 and 1.10.1 It is important to understand that jQuery 2.0.2 doesn’t supersede version 1.10.1 They are both the latest release and the only difference is that jQuery 1.10.1 preserves support for older versions of Internet Explorer You should use jQuery 2.x if you are sure that none of your users will have Internet Explorer 6, 7, or If that is not the case—or if you are not sure—then you should use jQuery 1.x These versions of IE are still widely used, especially in large corporations, and you should think carefully about the effect of using the 2.x line There are no legacy users in the idealized world of programming books, and I’ll be using the jQuery 2.0.2 library throughout most this book—but you can substitute any version of the jQuery 1.x line (from version 1.9 onward) and get the same result and preserve support for the old versions of IE ■■Tip I use jQuery 1.x in Part 4, when I describe jQuery Mobile jQuery Mobile tends to lag behind the main jQuery release and, as I write this, only supports jQuery 1.x What’s New for jQuery UI? jQuery UI has also been updated The API for using the existing user interface widgets has been updated to be more consistent and to work more closely with the HTML elements that underpin them and some new widgets have been added Throughout Part of this book, you will find that I show the important changes at the start of each chapter, just as I did for the changes to jQuery itself in Part What’s New for jQuery Mobile? jQuery Mobile has matured a lot since the previous edition of this book The API has been normalized, new widgets have been added, and the overall developer experience is much more consistent with jQuery and jQuery UI To reflect this maturity, I have completely rewritten Part to bring it in line with the rest of the book There are more examples, reference tables, and demonstrations of specific features Chapter ■ Putting jQuery in Context What Else Is New? From Chapter 12 onward, I use templates to generate HTML elements from data This is an important technique and I use it liberally The library that I used in the previous edition has reached the end of its life and I have chosen a replacement The new library doesn’t come with direct integration into jQuery and so in Chapter 12, I provide a custom plug-in that makes using the template library I selected easy to use with jQuery All of the examples that follow Chapter 12 have been revised to use the new library I changed the toolset that I use for testing mobile applications, preferring to use a cloud-based testing service rather than maintaining my own emulators I explain why I have done this in Chapter 27 Are There Lots of Examples? There are loads of examples One of the nice aspects of jQuery is that almost any task can be performed in several different ways, allowing you to develop a personal jQuery style To show the different approaches you can take, I have included a lot of different examples—so many, in fact, that I include the complete HTML document you are working with only once in some chapters in order to fit everything in The first example in every chapter is a complete HTML document, as shown in Listing 1-1, for example Listing 1-1. A Complete Example Document Example $(document).ready(function () { $("img:odd").mouseenter(function (e) { $(this).css("opacity", 0.5); }).mouseout(function (e) { $(this).css("opacity", 1.0); }); }); Jacqui's Flower Shop Aster: Daffodil: Chapter ■ Putting jQuery in Context Rose: Peony: Primula: Snowdrop: Place Order This listing is taken from Chapter Don’t worry about what it does; just be aware that the first example in each chapter is a complete HTML document, similar to the one shown in Listing 1-1 Almost all of the examples are based around the same basic HTML document, which displays a simple flower shop It isn’t the most exciting example, but it is self-contained and includes all of the things we are interested in when working with jQuery For the second and subsequent examples, I only show you the elements that change This is generally just the script element, which is where your jQuery code lives You can spot a partial listing because it starts and ends with ellipsis ( ), as shown in Listing 1-2 Listing 1-2. A Partial Listing jQuery(document).ready(function () { jQuery("img:odd").mouseenter(function(e) { jQuery(this).css("opacity", 0.5); }).mouseout(function(e) { jQuery(this).css("opacity", 1.0); }); }); Listing 1-2 is a subsequent listing from Chapter You can see that just the script element appears, and I have highlighted a number of statements This is how I draw your attention to the part of the example that shows the jQuery feature I am using In a partial listing like this, only the element I show has changed from the complete document shown at the start of the chapter Chapter ■ Putting jQuery in Context I have kept the examples in this book very focused on individual features This is to give you the best coverage of how jQuery operates But in doing this, you can lose sight of how different features fit together, so at the end of each part of the book, there is a short chapter in which I refactor the example document to incorporate all of the topics in the previous chapters and present a joined-up view of what’s possible Where Can I Get the Example Code? You can download all the examples for all the chapters in this book in the Source Code/Download area of the Apress web site (www.apress.com) The download is available without charge and includes all of the supporting resources that are required to re-create the examples without having to type them in (including images, JavaScript libraries, and CSS style sheets) You don’t have to download the code, but it is the easiest way of experimenting with the examples and cutting and pasting techniques into your own projects ■■Tip Even though I list just the changes in a lot of the code listings in the chapters, each example in the source code download is a complete HTML document that you can load directly into your browser What Software Do I Need for This Book? To follow the examples in this book, you will need various pieces of software, as described in the following sections Getting jQuery The very first thing you need is the jQuery library, which is available from http://jquery.com There is a download button right on the front page of the web site and an option to choose either the production or development release, as shown in Figure 1-1 Figure 1-1.
