This example calculates the cost of a name plaque. However, once you have grasped the basics, we hope it will continue to be a helpful reference as you create your own scripts.Ĭonsider how you might approach a different type of script. Unless you are already a confident programmer, you will probably find it helpful to read the book from start to finish the first time.
This includes filtering a gallery of images, and re-ordering the rows of a table by clicking on the column headings.Ĭhapter 13 deals with form enhancements and how to validate form entries. Not only will you see a selection of in-depth examples, you will also learn more about the process of designing and writing scripts from scratch.Ĭhapter 10 deals with error-handling and debugging, and explains more about how JavaScript is processed.Ĭhapter 11 shows you techniques for creating content panels such as sliders, modal windows, tabbed panels, and accordions.Ĭhapter 12 demonstrates several techniques for filtering and sorting data. This section brings together all of the techniques you have learned so far, to give you practical demonstrations of how JavaScript is used by professional developers. Along the way you will learn how it is used to create more engaging, interactive, and usable websites.Ĭhapter 1 looks at some key concepts in computer programming, showing you how computers create models of the world using data, and how JavaScript is used to change the contents of an HTML page.Ĭhapters 2-4 cover the basics of the JavaScript language.Ĭhapter 5 explains how the Document Object Model (DOM) lets you access and change a document’s contents while it is loaded into the browser.Ĭhapter 6 discusses how events can be used to trigger code.Ĭhapter 7 shows you how iQuery can make the process of writing scripts faster and easier.Ĭhapter 8 introduces you to Ajax, a set of techniques that allow you to just change part of a web page without reloading the entire page.Ĭhapter 9 covers Application Programming Interfaces (APIs), including new APIs that are part of HTML5 and those of sites like Google Maps.īy this point you will already have seen many examples of how JavaScript is used on popular websites.
The first nine chapters introduce you to the basics of programming and the JavaScript language. Chapter 12: Filtering, Searching & SortingĬhapter 13: Form Enhancement & Validation CORE CONCEPTS
