Errata

On page 16, topic 8 it's explained how to run a webpage however this doesn't work.

Instead of running you get an error :

Unable to start program 'http://localhost:52780/index.html
The system cannot find the file specified

Searching the web it seems to be an issue for which there's no solution unless using another default browser.

Would be good if it can be explained how to get this working as described in the book (so this means with IE) or what the best solution is atm until Microsof fixes the bug

There's also more information here:

Note from the Author or Editor:
This does indeed appear to be an issue with the Release Candidate of Visual Studio 2012 (it was still called Visual Studio 11 when the book was being written) when using on Windows 8.

Hopefully Microsoft will address the issue soon, though I'm not sure if it's related to Visual Studio or Windows 8. Using one of the workarounds in the link appears to fix the issue. I believe this only applies to the specific combination of the Visual Studio RC and the RTM version of Windows 8, since it obviously worked for me to take the screenshot. :-)

"...in JavaScript everything except numbers, strings, Booleans, undefined, and null are objects."

Aren't numbers and strings objects also?
-------------------------------------------------------
P.52 "...we haven't discussed functions."

Actually you start chapter 3 by discussing functions!

Note from the Author or Editor:
Actually, numbers and strings are not objects. There are Number and String wrapper objects to the primitive types but the data types are primitives.

As to the "we haven't discussed functions" part, you're right. :-) We moved some sections around and that didn't get updated.

If users downloaded the latest version of jQuery - 1.9x then the toggle method no longer works as described. Basically it just hides the #mover div. It was deprecated in 1.8.

To do something similar using the click event
$('#mover').click(function () {
var toggle = $.data(this, 'clickToggle');
if (toggle) {
$('.moveit').appendTo('#mover');
} else {
$('.moveit').appendTo('#movedest');
}
$.data(this, 'clickToggle', !toggle);
});

.toggle(function, function, ... ) removed

This is the "click an element to run the specified functions" signature of .toggle(). It should not be confused with the "change the visibility of an element" of .toggle() which is not deprecated. The former is being removed to reduce confusion and improve the potential for modularity in the library. The jQuery Migrate plugin can be used to restore the functionality.

The code for the space travel demo differs from that in the downloadable companion content. Specifically, the downloadable index.html for Chapter 7 needs to be changed to point to css/StyleSheet1.css. You'll also need the correct theme for jQuery UI. I used ui-lightness which needs to be in the css directory. That may differ depending on your jQuery UI version and theme.

Finally, as pointed out in the book, space.js is the name of the JavaScript file for this demo and that's found in the js folder in the companion content. You'll need to change index.html to js/space.js to reflect that.
