<p>I have the following jQuery Code:</p> <pre><code>$("#menu span").click(function() { var url = this.getAttribute("data-url"); var mobile = this.getAttribute("data-mobile"); var facebook = this.getAttribute("data-facebook"); if (url) { } if (mobile) { } if (facebook) { } }; </code></pre> <p>But it is a little glitchy. Is there an alternative I can use to see if this data attribute exists? Instead of using <code>if (url) { }</code></p> <p>My HTML will be something like this:</p> <pre><code><ul> <li><span data-mobile="1" data-url="http://url.com">Site #1</span></li> <li><span data-url="http://site2.com" data-facebook="http://fblink">Site #2</span></li> <li><span data-url="http://site3.com">Site #3</span></li> </ul> </code></pre> <p>So not everyone will have all of the data attributes. </p> <hr> <p><strong>Edit:</strong> How do I clear everything once the span is clicked again?</p> <p>For example:</p> <pre><code>if (data.mobile) { $(".mobile").attr("data-link", data.mobile); $(".mobile").attr('class', 'icon mobile on'); } </code></pre> <p>So by default, the class is loaded with <code>icon mobile off</code>. Then when the span is clicked, it runs through the functions, and if it has mobile assigned to it, then it will turn the class to <code>icon mobile on</code> which is perfect for the first view. But then when I go to another span and it does not have a mobile, it still stays ON from before. How can I clear stuff like that on each new click?</p> <pre><code><div class="icons"> <div class="icon website off" data-link=""></div> <div class="icon mobile off" data-link=""></div> <div class="icon fb off" data-link=""></div> </div> </code></pre>

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.
