JavaScript: Visual QuickStart Guide (8th Edition)

This is the Chinese translation of JavaScript: Visual QuickStart Guide, 8th Edition, a bestselling introductory title from Peachpit Press, co-authored by Tom Negrino and Dori Smith and published in the Turing Program Design Series · Web Development line. The book follows a task-driven, step-by-step illustrated approach. It opens with entry-level questions such as what JavaScript is and how it differs from Java, then moves through the language fundamentals—variables and data types, operators, conditionals and loops, functions, objects, and arrays—before turning to practical use in the browser: manipulating page elements through the DOM, handling images and image rollovers, scripting browser windows, building drop-down menus and ad banners, constraining user input with form validation and regular expressions, saving state with cookies, and exchanging data asynchronously with a server via Ajax. The 8th edition adds two new chapters on the jQuery framework, covering both fundamentals and practical examples, so that readers unfamiliar with programming details can still use JavaScript sensibly on their sites. Throughout, the book advocates unobtrusive scripting—keeping behavior separate from HTML structure and CSS presentation—and is supported by example scripts used across the chapters and a companion website. Appendices provide a syntax reference and further resources. It suits beginners in web development and can also serve as a course textbook.
