<p><a href="https://stackoverflow.com/questions/3057628/how-to-self-identify-the-position-of-a-scripts-tag-in-the-dom">This question of mine</a> (currently unanswered), drove me toward finding a better solution to what I'm attempting.</p> <h2>My requirements:</h2> <p>• Chunks of code which can be arbitrarily added into a document, without an <code>id</code>:</p> <pre><code><div class="thing"> <elements... /> </div> </code></pre> <p>• The objects are scanned for and found by an external script:</p> <pre><code>var things = yd.getElementsBy(function(el){ return yd.hasClass('thing'); },null,document ); </code></pre> <p>• The objects must be individually configurable, what I have currently is identifier-based:</p> <pre><code><div class="thing" id="thing0"> <elements... /> <script type="text/javascript"> new Thing().init({ id:'thing0'; }); </script> </div> </code></pre> <p>• So I need to ditch the identifier (<code>id="thing0"</code>) so there are no duplicates when more than one chunk of the same code is added to a page</p> <p>• I still need to be able to config these objects individually, without an identifier</p> <hr> <p>SO! All of that said, I wondered about creating a dynamic global variable within the script block of each added chunk of code, within its script tag. As each 'thing' is found, I figure it would be legit to grab the innerHTML of the script tag and somehow convert that text into a useable JS object.</p> <p>Discuss.</p> <p>Ok, don't discuss if you like, but if you get the drift then feel free to correct my wayward thinking or provide a better solution - please!</p> <p>d </p>

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.
