DOM Scripting: Web Design with JavaScript and the Document Object Model (2nd Edition)

This book is the Chinese translation of the second edition of DOM Scripting: Web Design with JavaScript and the Document Object Model, co-authored by longtime web standards advocate Jeremy Keith and web developer Jeffrey Sambells. The book proceeds by first explaining the principles clearly and then putting them into practice: it opens with a review of the history of JavaScript and the DOM, tracing the browser wars and the development of standards; it then explains JavaScript fundamentals in plain language (statements, variables, data types, arrays and objects, conditionals and loops, functions) and systematically introduces the DOM node model—element nodes, text nodes, attribute nodes—along with common methods for getting elements and reading and writing attributes. Building on this, the book advances step by step through a JavaScript image gallery case study, from the initial simple implementation to a complete separation of structure and behavior: it covers a set of core front-end development principles including graceful degradation, progressive enhancement, backward compatibility, object detection, and performance optimization, and demonstrates how to dynamically create markup, enrich document content, read and write styles via CSS-DOM, and create controllable animation with timers. The second edition also adds discussion of HTML5 (Canvas, audio and video, new form features) and JavaScript libraries such as jQuery, and the final chapter ties together the book's knowledge through a complete site project. The book is modest in length but excels at explaining why code is written the way it is, and it is a well-regarded introductory classic among Chinese front-end readers.
