While "Ajax: The Definitive Guide" is certainly exhaustive, it's hard to have confidence in a text so riddled with errors. Other O'Reilly titles I've purchased in the last few years suffer from the same problem: very poor copy editing. In a "Definitive Guide," this is inexcusable.Furthermore, he author's decision to rely on the Prototype framework is misguided. It saves a few lines of code per page, but one expects a "Definitive Guide" to define, explore, and use the actual objects and methods defined by the language itself, not those defined in one of many, many external libraries.It is also somewhat comical to read on page 10 that developers, rather than browser vendors, "are to blame for not adopting standards" and that they are "stuck with the mentality of the 1990s, when browser quirks mode, coding hacks, and other tricks were the only things that allowed code to work in all environments," and then to read on page 191 that "Yes, there are always caveats in the world of standards compliance" and that "Example 7-2 will not work in Internet Explorer because Internet Explorer does not support the CSS2 rules that are used to make this work." And on page 187 that "Internet Explorer does not natively support :hover on elements other than . For this reason, instead of using the CSS that will work for all other browsers, we must use this...."(It's hard not to laugh, too, at a sentence that begins with "To take the file menu example fully to the Web 2.0 level....")By the time all the errata are corrected and a second edition issued, it might be appropriate for the author to wag his finger at developers who can't yet afford to to be totally standards-pure, but by then the faddish jargon will seem very dated.And until O'Reilly starts employing copy editors, I'm not buying the first edition of any title they release.
