    <p>I'm trying to use "nth-child(n)" with Prototype, as I do with jQuery. A code example is below...</p> <pre><code>function myFunction() { $$('div.amfinder-horizontal td:nth-child(1) select').simulate('click'); $$('div.amfinder-horizontal td:nth-child(1) select').simulate('change'); } Event.observe(window,"load",myFunction); </code></pre> <p>Unfortunately, this doesn't appear to be selecting the element (as the click and change don't work). When I put the class of the select in there, it does work... but I can't use the class and need to do it via nth-child. I believe :first and :last works, but I have 6 total that I need to do this for.. and even then, it won't always be all 6 of them.</p> <p>If someone could provide an example of nth-child and how it could work with Prototype, that'd be great!</p> <pre><code>&lt;div class="amfinder-horizontal" id="amfinder_529e1406aff23Container"&gt; &lt;table&gt; &lt;tbody&gt; &lt;tr&gt; &lt;td&gt; &lt;div class="dropdown-title"&gt;Year&lt;/div&gt; &lt;div class="dropdown-element active"&gt; &lt;select name="finder[424]" id="finder-72--424" style="width: 101px;" class="active"&gt;

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.
