There is no DOCTYPE and there is no closing html </html> element. This is also an
issue in downloaded examples.

first dynamic example

The first dynamic example, the one with the "Click Here!" link that displays a bunch of property
information about the event that triggered the dynamic display, does not work on IE6.

Dynamic Behavior in a Blink example code

There seems to be some code missing. The example isn't very clear and the code as
written on these two pages doesn't run. It seems like some "br" html codes were
left out or actually interpreted on the published page as line breaks.

code sample at top of page still not correct after reading errata

There is errata for this code, but it doesn't address this. The line:
$("sandbox").innerHTML = Clicked at " + new Date() + ". Event: " + ev + ";

should be:
$("sandbox").innerHTML = "<p>Clicked at " + new Date() + ". Event: " + ev + ". </p><hr />";

if you want it to appear like the screenshot in the book.

php code

On my php5 installation I am required to use <?php to start php start blocks. I
"think" this is a php5 convention and since php5 is a requirement you might consider
using <?php.

Missing call after clearTimeout

Continued code elements from previous page

A whole range of resource links that support this book are now dead.

In this case the ajaxCaller.js script is no longer accessible. This type of problem is repeated with various other resources throughout the book. This is a critical issue for two reasons:

1. The code snippets that are in the book cannot be relied upon due to typo and truncating errors (see other errata).

2. Even if the code snippets were correct they are not complete.

The book's useability is directly linked to the availability of the historic online resources; please re-instate.

7nd paragraph

"If absolute, the coordinates are relative to the top-left of the entire document."

This is wrong. If positioning is set to absolute, the containing block is set to the
nearest ancestor with a positioning other than static.

9th paragraph

<quote>Positioning is set with standard CSS styles:

message.style.left = "150px"</quote>

should be changed to something like

<quote>Positioning is set with standard CSS styles:

message.style.positioning = "absolute"</quote>

Either the ellipses should be moved to the last line or the function call should be
closed with something like

6th paragraph

On page 98/99 it says that the content type header should be "text/xml". Here it says
that the content type header should be "text/html". I think this should be
clarified. Can it be both or is one statement incorrect?

"Content-Type" header for XML response should be "text/xml" and not "text/html".

2nd code snippet

I believe the line:

should read:
event = ev || window.event;

Can you confirm this?

the bold line

The sentence beginning "That's not possible" makes little sense.

Now that IE7 supports XMLHttpRequest() directly, it makes no sense to do the "new
XMLHttpRequest()" last instead of first.

I think you meant this paragraph to be about version-dependent behavior. It would
make much more sense if it does.

document.getElementById("board") should not be done repeatedly within the loop.
The line beginning "the last 4 args" should be a comment.
