Description
In essence, it reminds me of how I learned to work on the web in the first place: careful examination of other people�??s work. At its best, this book is a clearly annotated view source of Koch�??s projects. It�??s a comprehensive exploration of Koch�??s thoughts about the problems he�??s run into (problems that you�??ll run into, too), how he approached them, and ultimately how he�??s solved them." -- Mike West, Managing Editor, Digital Web Magazine
Présentation de l'éditeur
This is the eBook version of the printed book.
Whether you're an old-school scripter who needs to modernize your JavaScripting skills or a standards-aware Web developer who needs best practices and code examples, you'll welcome this guide from a JavaScript master.
Other JavaScript books use example scripts that have little bearing on real-world Web development and are useful only in the chapter at hand. In contrast, Peter-Paul Koch's book uses eight real-world scripts he created for real-world clients in order to earn real-world money. That means the scripts are guaranteed to do something useful (and sellable!) that enhances the usability of the page they're used on.
The book's example scripts include one that sorts a data table according to the user's search queries, a form validation script, a script that shows form fields only when the user needs them, a drop-down menu, and a data retrieval script that uses simple Ajax and shows the data in an animation.
After an overview of JavaScript's purpose, Peter-Paul provides theoretical chapters on the context (jobs for JavaScript, CSS vs. JavaScript), the browsers (debugging, the arcana of the browser string), and script preparation. Then follow practical chapters on Core, BOM, Events, DOM, CSS Modification, and Data Retrieval, all of which are explained through a combination of theoretical instruction and the taking apart of the relevant sections of the example scripts.
