JavaScript: Visual QuickStart Guide, 9th Edition

This is the Chinese edition of the ninth edition of JavaScript: Visual QuickStart Guide, a long-bestselling introductory JavaScript tutorial. The original book has been continuously revised since the 1990s and has sold more than a million copies worldwide. Organized around a "task-driven + step-by-step illustrated" approach, the book begins with concepts such as "what JavaScript is and why it is not Java," then guides readers through the language basics—variables and operators, functions and loops, arrays and strings, event handling—and applies that knowledge to specific webpage effects: image rollovers, looping ad banners and slideshows, pop-up windows and frame control, form validation, regular expressions, cookies and state memory, adding/removing/replacing DOM nodes, and practical examples such as dynamic dates, countdowns, and collapsible menus. The ninth edition has been fully rewritten: all sample code follows W3C HTML5 standards and is compatible with IE 9 and later, Firefox, Safari, Chrome, Opera, and other modern browsers and mobile devices; several new chapters cover using the jQuery framework to quickly add interactivity to pages (including jQuery UI effects, table sorting, autocomplete, and drag-and-drop), and a dedicated chapter explains mobile scripting with touch events, screen orientation, and device geolocation, along with a chapter introducing lightweight extensions such as bookmarklets. The appendices provide the evolution of JavaScript versions, a reserved-word list, a CSS reference, and further learning resources. The book has 18 chapters and about 700,000 words; it is suitable as a first JavaScript book for complete beginners studying on their own, and as an introductory textbook for university web development courses.
