This page was updated July 18, 2007.

Here's a key to the markup:
	[page-number]: serious technical mistake
	{page-number}: minor technical mistake
	<page-number>: important language/formatting problem
	(page-number): language change or minor formatting problem
	?page-number?: reader question or request for clarification



(xxi)  2nd paragraph;
"His suggestions and technical corrections have make the book clearer and 
more precise."
Should be:
"His suggestions and technical corrections have made the book clearer and 
more precise."


(9)  near bottom of program example;
total.innerHTML = ""
Should be:
total.innerHTML ="";


(106)  para 1 (after chapter heading);
Superfluous comma after "Chapter 3".


(137) first whole paragraph, first sentence;
'rather that as a method'
should be:
'rather than as a method'


(170): Change the 3rd sentence of 9.5.1 so it begins: 
"If you have only one level of subclass, you can simplify the syntax..."

At the end of the last paragraph of 9.5.1, add the following:

     Note however that this trick only works with shallow inheritance
     hierarchies.  If B is a subclass of A and C is a subclass of B, and
     both B and C use this superclass trick, then when you create an
     instance of C, this.superclass will refer to B(), and the B()
     constructor will recurse infinitely.  For anything other than simple
     subclasses, use the construtor chaining technique shown in Example
     9-3.


(143) first sentence;
"The facts that Javascript ..."
should be
"The fact that Javascript ..."


(171): At the end of section 9.5.2 add a new paragraph:

     Again, note that this superclass property can only be used once
     within an inheritance hierarchy.  If a class and a subclass both use
     this trick, it will cause infinite recursion.


(275)  code sample, 3rd block;
  
  var viewportWidth = window.innerWidth;
  var viewportHeight = window.innerWidth;

Should be:
  
  var viewportWidth = window.innerWidth;
  var viewportHeight = window.innerHeight;



(277)  First "if" statement top half of page;
"documentElemnet" should be "documentElement"


(411): Delete the first two sentences of 17.3.2, and replace them with:

     Although the IE event model provides event details in an Event
     object, IE only passes an event object to handlers registered with
     the non-standard <literal>attachEvent()</literal> method (described
     below). Other event handlers are invoked with no arguments.  Instead
     of passing the Event object as an argument to the handler, IE makes
     it available as the <literal>event</literal> property of the global
     Window object.


(412): Insert the following as the second sentence of the second paragraph of 17.3.3:

     An event handler registered with <literal>attachEvent()</literal>
     will be invoked with a copy of the global
     <literal>window.event</literal> event object.


(478) footnote, second sentence;
"repuration" should be "reputation"


(479): Add the following just before the start of 20.1.1:

     The examples in this section and the rest of the chapter are all
     part of one larger module.  They define utility functions in a
     namespace (see Chapter 10) named <literal>HTTP</literal>.  None of
     the examples include the code to actually create this namespace,
     however.  The example download bundle includes a file named http.js
     that includes this namespace-creation code, and you can simply add
     the single line <literal>var HTTP = {};</literal> to the examples
     shown here.


(503): Add the following right before 21.1.1:

     These utility functions are intended to be part of one large module,
     and are all placed in a namespace (see Chapter 10) named XML. The
     examples shown here do not include code to actually create this
     namespace, however.  The example download bundle includes a file
     named xml.js that includes this namespace-creation code, and you
     can simply add the single line <literal>var XML = {};</literal> to
     the examples shown here.


(707)  3rd-to-last line on page
"This provides a useful alternative to String.substring( ) and String.splice( )"
String.splice()
should be
String.slice()


(933)  Title line for XMLHttpRequest;
Internet Explorer 5.0
should be
Internet Explorer 7.0
