    <p>The only advantage that I can think of to using <code>javascript:void(0)</code> is that it will be supported even by the oldest browsers. That said, I would use one of the other <em>unobtrusive</em> approaches you have mentioned:</p> <ul> <li>For most uses, <code>event.preventDefault()</code> and <code>return false</code> can be used interchangeably.</li> <li><code>event.preventDefault()</code> will prevent the page from reloading, as desired, but will allow the click event to bubble up to the parent. If you want to stop the bubbling, you can use it in conjunction with <code>event.stopPropagation</code>.</li> <li><code>return false</code> will additionally stop the event from bubbling up to the parent.</li> </ul> <p>I say 'interchangeably' in the first point above because much of the time we do not care whether or not an event bubbles up to the parent(s). However, when <em>do</em> we need some fine-tuning, we should consider points two and three.</p> <p>Consider the following example:</p> <pre><code>&lt;div&gt;Here is some text &lt;a href="www.google.com"&gt;Click!&lt;/a&gt;&lt;/div&gt;​ $("a").click(function(e) { e.preventDefault(); }); $("div").click(function() { $(this).css("border", "1px solid red"); }); ​ </code></pre> <p>Clicking on the anchor will prevent the default action of the event from being triggered, so the browser will not redirect to www.google.com. However, the event will still 'bubble up' and cause the div's click event to fire, which will add a border around it. Add <code>e.stopPropagation()</code> <em>or just</em> <code>return false</code> and the div's click event will not fire. You can mess with it here: <a href="http://jsfiddle.net/cMKsN/1/" rel="noreferrer">http://jsfiddle.net/cMKsN/1/</a></p>

    1. COOut of interest: is calling `event.precentdefault()` at the top of your handler effective if an exception occurs after that in your handler code?

    2. CO@sje397 Yeah, if you have `event.preventDefault(); someFunction();` and something breaks with someFunction(), the default event is still stopped.

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).
