    <p>To save me a lot of work editing a number in when adding a document to a site I decided to use javascript to count the number of elements with a class <code>doc</code> .</p> <p>I am two main problems:</p> <ul> <li><p>There is trouble displaying the variable. I initially thought this was because I hadn't added <code>function</code>, however when I tried adding this the variable was still not displayed.</p></li> <li><p>The elements with the class I want to count are on another page and I have no idea how to link to it. For this I have tried <code>var x = $('URL: /*pageURL*/ .doc').length;</code> which hasn't worked. </p></li> </ul> <p>Essentially I want the total elements with said class name and this to be displayed in a span element. </p> <p>Currently I have something similar to what's displayed below:</p> <pre><code> &lt;script&gt; var Items = $('.doc').length; document.getElementById("display").innerHTML=Items; &lt;/script&gt; &lt;span id="display"&gt;&lt;/span&gt; </code></pre> <p>Found an example of something similar <a href="http://en.wikipedia.org/wiki/Special%3aStatistics" rel="nofollow">here</a> where the total numbers of articles are displayed.</p> <p><strong>Edit:</strong> </p> <p>@ian This code will be added to the homepage, domain.net/home.html. I want to link to the page containing this documents, domain.net/documents.html. I've seen this done somewhere before and if I remember correctly they used <code>url:domainname.com/count</code> somewhere in their code. Hope this helps.</p>

    2. COAre you trying to identify elements on a different DOM? I don't think that can be done. Unless you want to use a very complex AJAX solution.

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.
