    <p>I have this code in <code>&lt;script&gt;</code> tags at the top of my HTML file.</p> <pre><code> $(document).ready(function() { $('#scrollbar1').tinyscrollbar(); $('a.jqtree_common').click(updateScrollbar()); }); $(function updateScrollbar() { var oScrollbar = $('#scrollbar1'); oScrollbar.tinyscrollbar(); oScrollbar.tinyscrollbar_update(); $('a.jqtree_common').click(updateScrollbar()); }); </code></pre> <p>But for some reason when I run this, it says <code>updateScrollbar()</code> is undefined within <code>(document).ready</code>. When I try to define <code>updateScrollBar()</code> inside of <code>(document).ready</code> then <code>updateScrollBar()</code> gets caught in some kind of endless loop.</p> <p>My question is twofold:</p> <ol> <li>What can I do to make <code>updateScrollBar()</code> defined within the scope of <code>(document).ready</code>?</li> <li>Is there a better way to assign this function to the <code>'a.jqtree_common'</code> elements? They are created dynamically at runtime, and modified as the webpage is used. I want the function to run every time one of them is clicked.</li> </ol> <p>I'm using tiny <a href="http://baijs.nl/tinyscrollbar/" rel="nofollow">scrollbar</a> and <a href="http://mbraak.github.io/jqTree/#jqtree" rel="nofollow">jqtree</a></p> <p>EDIT: I want the <code>$('a.jqtree_common').click(updateScrollbar);</code> assignment to be made every time the scrollbar is updated, since I believe clicking on a <code>'a.jqtree_common'</code> element creates more <code>'a.jqtree_common'</code> elements.</p>

    1. COjust remove the `$(` and `);` surrounding your function. The DOM doesn't need to be ready to declare the function.

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.

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