Javascript, w. CD-ROM (Programmer to Programmer) [Illustriert] [Taschenbuch]

This is a reference, so don't expect it to teach you JavaScript through any sort of tutorial (although reading the object descriptions can be very illuminating). Cliff Wootton has chosen to organise his work alphabetically, like a giant encyclopaedia of objects, reserved words, operators, filters, and other aspects of JavaScript and the DOM standards. As an appendix he includes a cross-reference which associates individual properties, methods, and event handlers with the objects to which they belong. Once you've located the entry you want, you'll have easy access (in the case of an object) to inheritance information, a syntax summary, and plain-English advice on what the object does. Tables provide implementation details for each property, method, and event handler, so you know what versions of which browsers support the language feature you wish to use. There are also references to standards documents and occasional illustrations of how to use the language element in working code. Though rare the illustrations are generally effective in clarifying the significance of language elements and the relationships among objects.

Cool features include Wootton's documentation of common errors and incorrect assumptions. For example, he's included an entry on Bar.visibility, a nonexistent property sometimes assumed to exist in the Netscape Navigator object model. The correct property is Bar.visible, the author points out. Also note that operators and other non-character entries don't appear at the front, before the "A" entries, as is conventional. They've been "transliterated", if that's the word, so you have to look up "Add" in order to find out about the + operator. Overall though, this is a fine JavaScript reference made excellent by its companion CD-ROM, which includes the entire body of printed reference material (plus some extra) in searchable form. --David Wall

This is a reference, so don't expect it to teach you JavaScript through any sort of tutorial (though reading the object descriptions can be very illuminating, indeed). Cliff Wootton has chosen to organize his work alphabetically, like a giant encyclopedia of objects, reserved words, operators, filters, and other aspects of JavaScript and the DOM standards. A cross-reference that associates individual properties, methods, and event handlers with the objects to which they belong appears as an appendix. Once you've located the entry of the object you want, you'll have easy access to inheritance information, a syntax summary, and plain-English advice on what the object does. Tables provide implementation details for each property, method, and event handler, so you know which versions of which browsers support the language feature you want to use. There also are references to standards documents, and, sometimes, illustrations of how to use the language element in working code. Illustrations are rare but generally effective in clarifying the significance of language elements and the relationships among objects.

A cool feature is Wootton's documentation of common errors and incorrect assumptions. For example, he's included an entry on Bar.visibility, a nonexistent property sometimes assumed to exist in the Netscape Navigator object model. The correct property is Bar.visible, the author points out. The book also has some strange ways of doing things: Operators and other non-character entries don't appear up front, before the "A" entries, as is conventional. They've been transliterated, if that's the word, so you have to look up "Add" in order to find out about the + operator.

Topics covered: The JavaScript, JScript, and ECMAScript scripting languages, and their implementations in popular browsers as well as in standards documents. Coverage includes JavaScript through version 1.5, JScript through version 5.5, and ECMAScript through version 3. The DOM1 standard is covered fully and the DOM2 standard is covered to the extent it's implemented in Netscape Navigator 6. Effectively, this means coverage includes Netscape Navigator through version 6.0, Internet Explorer through version 5.5, and Opera through version 5. There's also some coverage of server-side JavaScript under Netscape Enterprise Server.
