The description of the Microsoft IE event handling, in chapter 17, is simply wrong. Not typos, just wrong. In my version IE version 6, event handlers registered with addEvent *are* called with the triggering event as an argument, contrary to the text and examples. Specifically, the IE-specific portion of the
"portableEventHandler" code at the bottom of page 411 is never called because "e" is never empty. I wasted far more time than I should have because I relied on this behavior in writing my own event handling code.

Similarly, the "Form Verification Example", on pp 451-455, doesn't work in an xhtml strict environment. In the overly-brief section on the doctype tag (page 366), no mention is made of the impact on javascript of specifying "strict. The various html attributes ("required", "pattern", etc) will properly cause a strict w3c validator to declare a violation.

Although I submitted errata reports to this website, I've received no response and no indication that they were ever received -- never mind acted on.

This is an expensive ($49.99) paperback, and I expect more than I got. Stick with the 4th edition.
