Do you spend too much time doing repetitive production tasks such as
placing and replacing images, resizing them, dragging them from one
document to another, and preparing images for printing instead of being
creative? Do you use Adobe Photoshop CS2 and have some experience with
scripting? You’re in luck. Since Adobe Creative Suite 2 was created
with built-in support for scripting, virtually every repetitive or
time-consuming task that creative professionals have to do in the Adobe
Creative Suite can be streamlined with the help of a script. This book
describes how to use JavaScript to manipulate and extend Adobe
Photoshop within Adobe Creative Suite 2, and provides reference
information for the JavaScript objects, properties, and functions
defined by Adobe’s applications. Now available in print for the first
time, this scripting reference provides the information experienced
JavaScript users need to create custom scripts for Photoshop, whether
you’re looking to automate Camera Raw options and settings,
automatically resize and export large batches of images into your
page-layout application, or want to automatically add metadata, like a
copyright notice, to selected image files. These are just a few
examples of how you can use Photoshop CS2’s built-in scripting
capabilities to save you from hours of repetitive tasks.

Since the earliest days of Internet scripting, Web developers have considered JavaScript: The Definitive Guide
an essential resource. David Flanagan’s approach, which combines
tutorials and examples with easy-to-use syntax guides and object
references, suits the typical programmer’s requirements nicely. The
brand-new fourth edition of Flanagan’s “Rhino Book” includes coverage
of JavaScript 1.5, JScript 5.5, ECMAScript 3, and the Document Object
Model (DOM) Level 2 standard from the World Wide Web Consortium (W3C).
Interestingly, the author has shifted away from specifying–as he did
in earlier editions–what browsers support each bit of the language.
Rather than say Netscape 3.0 supports the Image object while Internet
Explorer 3.0 does not, he specifies that JavaScript 1.1 and JScript 3.0
support Image. More usefully, he specifies the contents of independent
standards like ECMAScript, which encourages scripters to write
applications for these standards and browser vendors to support them.
As Flanagan says, JavaScript and its related subjects are very complex
in their pure forms. It’s impossible to keep track of the differences
among half a dozen vendors’ generally similar implementations.
Nonetheless, a lot of examples make reference to specific browsers’
capabilities. Though he does not cover server-side APIs, Flanagan
has chosen to separate coverage of core JavaScript (all the keywords,
general syntax, and utility objects like Array) from coverage of
client-side JavaScript (which includes objects, like History and Event,
that have to do with Web browsers and users’ interactions with them.
This approach makes this book useful to people using JavaScript for
applications other than Web pages.

On numerous online forums for JavaScript and DHTML, the majority of
questions begin with “How do I…?” This new Cookbook provides the
answers. After reading thousands of forum threads over the years,
author and scripting pioneer Danny Goodman has compiled a list of
problems that frequently vex scripters of various experience levels. He
has now applied state-of-the-art ECMA and W3C DOM standards and used
best practices to create this extensive collection of practical recipes
that can bring your web pages to life. The JavaScript & DHTML Cookbook
is all about adding value to the content of a web page. The book
focuses on practical and sensible applications of scripting, rather
than flying images and gratuitous color changes. For every problem
Goodman addresses, there’s a solution or “recipe”–a focused piece of
code that web developers can insert directly into their applications.
Yet, rather than just cut-and-paste code, you also get explanations of
how and why the code works, so you can learn to adapt the
problem-solving techniques to your designs. The recipes range from
simple tasks, such as manipulating strings and validating dates in
JavaScript, to entire libraries that demonstrate complex tasks, such as
cross-browser positioning of HTML elements and sorting tables. This
book contains over 150 recipes on the following topics:

• Working with interactive forms and style sheets
• Presenting user-friendly page navigation
• Creating dynamic content
• Producing visual effects for stationary content
• Positioning HTML elements
• Managing browser windows and multiple frames

There is a serious information gap for Webmasters learning
client-side JavaScript skills and trying to solve common Web-related
problems. Knowing the syntax is one thing, being able to build a useful
application is another. And while there are dozens of “how- to”
JavaScript books available, few literally hand the Webmaster a set of
ready-to-go, client-side JavaScript applications with thorough
documentation that enable the reader to fully understand and extend
those applications. By providing such a set of applications, JavaScript Application Cookbook
allows Webmasters to immediately add extra functionality to their Web
sites. This book targets readers with two different skill sets. The
primary target is JavaScript-knowledgeable Webmasters and designers who
can immediately begin constructing their own versions of the
applications. The secondary target is those with little or no
JavaScript experience. The included applications are ready for
immediate use and require little customization. This book explores both
the code and the techniques that are centered around core JavaScript
functionality, a functionality that will not become incompatible or
obsolete. The source file design of most applications and libraries
will help modularize reader Web sites and facilitate easier site
management and coding practices. Chapters are organized by application.
Among the included applications are:

• A client-side search
  engine that will show coders how to build their own search engine and
  get excellent results, all with a client-side tool
• A drag-and-drop greeting application that lets users custom build and send DHTML email greetings
• A GUI image rollover tool that generates cross-browser image rollover code for all versions of JavaScript
• A
  robust client-side shopping cart application that lets shoppers browse
  and shop, while the application keeps a tab of the shopper’s selections
  and a running bill, including tax and shipping
• An online test application that auto-administers, grades, and displays answers to online exams or surveys

Suitable for learning basic programming for Web browsers, Beginning JavaScript is a patient, introductory tutorial on writing scripts successfully. It teaches you how to create client-side scripts (including full coverage of fundamentals like variables and flow control, plus plenty of screen shots.)

JavaScript is a good way to learn programming. It’s powerful, of course, but the book takes small steps, using scripts that work with string and time data first, and then moving to manipulating browser objects like forms and windows. A running case study for a trivia game helps anchor the steps with a practical (and fun) example. There are plenty of tips on debugging your scripts (including how to use the Microsoft Script Debugger tool), and each section includes sample questions. (The book also offers extensive answers in over 80 pages at the end of the book.)

There’s plenty of material on the differences between Internet Explorer and Netscape, especially when it comes to Dynamic HTML (DHTML). Coverage of the Document Object Model (DOM) for browsers helps bring the text up to date on some of the latest standards in Web browsers (including the new Netscape 6). While the focus of Beginning JavaScript clearly is on the client, later sections turn to server-side ASP development (in which the sample trivia game is enhanced with ASPs written in JavaScript using ADO and Microsoft Access.) Reference sections on JavaScript and the browser object model for Internet Explorer and Netscape (through version 4.x) round out the material. In all, with its approachable style and clearly rendered code examples, Beginning JavaScript makes for a worthwhile first book of programming for today’s browsers. Even if you haven’t programmed before, this text can give you the tools you need to bring your static Web pages to life.
