    <p>Here's my situation:</p> <p>I've got a site that will cover 4 different subjects. I start out with 4 divs that each have the title of those subjects. For example,</p> <pre><code>&lt;div&gt;&lt;p&gt; Physics &lt;/p&gt;&lt;/div&gt; &lt;div&gt;&lt;p&gt; Chemistry &lt;/p&gt;&lt;/div&gt; &lt;div&gt;&lt;p&gt; Biology &lt;/p&gt;&lt;/div&gt; &lt;div&gt;&lt;p&gt; Math &lt;/p&gt;&lt;/div&gt; </code></pre> <p>When I click on the 'physics' div, I'd like another div to appear that elaborates on some physics problem or something. Another click causes the 'elaboration div' to disappear. I've got that working with one 'subject' here:</p> <p><a href="http://jsfiddle.net/yfrNn/2/" rel="nofollow">http://jsfiddle.net/yfrNn/2/</a></p> <p>This is the jQuery code I am using to accomplish this. </p> <pre><code>$(document).ready(function () { $(".phys").click(function () { if ($(".phys:last").css("visibility") == "visible") { $(".phys").css("visibility", ""); } else { $(".phys").css("visibility", "visible"); } }); });` </code></pre> <p>I could write this function 4 different times, once for each of the subjects I'm using, but would like a cleaner solution. I am wondering whether I can declare all of the divs in the following manner:</p> <pre><code>&lt;div class="subject phys"&gt;&lt;p&gt; Physics &lt;/p&gt;&lt;/div&gt; &lt;div class="subject chem"&gt;&lt;p&gt; Chemistry &lt;/p&gt;&lt;/div&gt; &lt;div class="subject bio"&gt;&lt;p&gt; Biology &lt;/p&gt;&lt;/div&gt; &lt;div class="subject math"&gt;&lt;p&gt; Math &lt;/p&gt;&lt;/div&gt; </code></pre> <p>And then have a certain click() function run whenever a "subject" div is clicked, have the code recognize which subject this particular div is referring to, and display the appropriate "elaboration div". </p> <p>I believe I could potentially do this with subclassing:</p> <pre><code>/* CSS */ div.subject{} .subject.phys{} .subject.chem{} .subject.bio{} .subject.math{} </code></pre> <p>Any thoughts? Is there a distinctly better way to implement something like this? </p> <p><strong>Edit</strong></p> <p>Here's an updated fiddle, with the HTML roughly as it will be in the implementation:</p> <p><a href="http://jsfiddle.net/yfrNn/6/" rel="nofollow">http://jsfiddle.net/yfrNn/6/</a></p>

    1. COYou can, but it would be better to instead use a data attribute in my opinion to store the target additional content element rather than a class,that way you don't have to parse through the classNames of the title element or have an if elseif elseif statement. Or, better yet, use an anchor tag since this is indeed a click event and store the id of the target element as the href of the anchor.

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.
