    <p>There are couple of things I hear in defense of progressive enhancement.</p> <p><strong>Javascript is off or not available.</strong> According to <a href="http://www.w3schools.com/browsers/browsers_stats.asp" rel="nofollow noreferrer">W3School's Javascript statistics</a>, 95% had Javascript enabled January 2008 (2.5 years ago). The trend, based on those stats, seems to be that Javascript enabled browsers are on the rise. Heavy AJAX adoption has probably pushed users to enable even faster. To support text-only or accessibility doesn't make a lot of sense from the business perspective since they probably account for less than &lt;1% of the traffic.</p> <p><strong>Mobile browsers won't work.</strong> I would either way create a mobile version of the site because of the limited screen size and a whole different browsing experience on the mobile devices. One could argue to use different CSS for screen readers/mobile devices, but you won't be able to crank up as much information on a mobile device no matter how tidy you make it look. </p> <p>The original statement isn't even true for the newer generation mobile devices, like the Android and iPhone, which have a total of >200,000 combined <strong>daily</strong> activation rate. Besides, most Javascript eye-candy (like jQuery UI) doesn't make much sense because the website experience on the mobile device is so different (no mouse hover, etc.). I consider mobile devices to be a platform of their own that needs a customized version of the website. Another trend has been creating a "native app" version of the website/service.</p> <p><strong>Spiders won't be able to crawl.</strong> This isn't true either. It's possible to use the DOM as a data container for the Javascript (populate div/input tags with your entities). Also, Google has made efforts to make <a href="http://code.google.com/web/ajaxcrawling/docs/getting-started.html" rel="nofollow noreferrer">AJAX websites crawlable</a>.</p> <p>Similar threads:</p> <ul> <li><a href="https://stackoverflow.com/questions/99748/How-important-do-you-think-Progressive-Enhancement-is-">How important do you think Progressive Enhancement is?</a></li> <li><a href="https://stackoverflow.com/questions/985784/javascript-detection-browser-statistics">JavaScript Detection / Browser Statistics</a></li> </ul> <p>Interesting links:</p> <ul> <li><a href="http://www.quirksmode.org/m/table.html" rel="nofollow noreferrer">Mobile compatibility tables</a> </li> <li><a href="http://code.google.com/web/ajaxcrawling/docs/getting-started.html" rel="nofollow noreferrer">Making AJAX Applications Crawlable</a></li> </ul>

    1. COThose are **not** W3C statistics. They are W3Schools' statistics which are generated from the self-selecting sample of users who want to learn how to build websites but haven't discovered that W3Schools has error prone and security hole ridden tutorials that should be avoided if at all possible.

    2. COFixed. Good catch! It seems hard to find unbiased JS usage statistics.

    3. COThat would be because it is impossible to collect truly unbiased JS usage statistics.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
