Page 17 Figure 1-1

Hello All,

I just bought the book last night and I'm a bit confused about a reference on page 17. It says,
"In Figure 1-1, you see what is probably a pretty common scenario: You have a thumbnail, and you can click to see a bigger version of the thumbnail. This is the kind of thing that JavaScript works well for â giving you the bigger version in a separate pop-up window that doesnât have any controls."

In my book Figure 1-1 is the "JQuery is not loaded" figure.

In addition, the download has does not have any figures for Chapter 1.

Please provide the cited figure.

thanks,

I took a quick look at the book and figure 1-1 is the "jquery not loaded" picture you mentioned. That does appear strange at first sight, as it does not match the words. However I took a look at the HTML and javascript that followed, I figured out what the author was talking - he was talking about the purpose of his code.

With that HTML page, if you click on the "Open Picture" link, a bigger version of the picture pops up. the event handler was not defined in the HTML, but added by the javascript.

Code:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
                      "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">

        <link rel='stylesheet' type='text/css' href='style.css' />
        <script type='text/javascript' src='thumb.js'></script>
    </head>
    <body>
        <p>
            <img src='pumpkin.jpg' alt='Pumpkin' />
            <a href='pumpkin.jpg'>Open Picture</a>
        </p>
    </body>
</html>

The point was that the text did not match printed figures in the book. And the downloads which are supposed to be the full code for the examples and figures were incomplete. Typing in the thumbnails example does result in working code. But the result was not shown in the book as expected.

You are correct. The section of Chapter 1 from Page 8 - Programming Conventions was taken from a different book (a Wrox Blox on the base2 Javascript framework) and it appears that the images and figure count where not updated correctly.

I've attached the image that should have appeared on Page 17 below.
