    <p>I'm new to JQuery, and Javascript, and I am using the JQueryUI ProgressBar, and every time somebody clicks on a button, then the progress bar animates and fills up. Is there a way to keep track of which buttons are already pressed to prevent the buttons from triggering the event again?</p> <p>Current HTML: </p> <pre><code> &lt;ul&gt; &lt;li&gt;&lt;a href="left/section1.html" target="leftcontainer" onClick="updateBar();window.presentation.location.href='right/section1/page1.html';;return true;"&gt;overview&lt;/a&gt;&lt;/li&gt; &lt;li&gt;&lt;a href="left/section2.html" target="leftcontainer" onClick="updateBar();window.presentation.location.href='right/section1/page1.html';;return true;"&gt;key features&lt;/a&gt;&lt;/li&gt; &lt;li&gt;&lt;a href="#" onClick="updateBar()"&gt;customers&lt;/a&gt;&lt;/li&gt; &lt;li&gt;&lt;a href="#" onClick="updateBar()"&gt;accessories&lt;/a&gt;&lt;/li&gt; &lt;!--&lt;li&gt;&lt;a href="#"&gt;nav5&lt;/a&gt;&lt;/li&gt; &lt;li&gt;&lt;a href="#"&gt;nav6&lt;/a&gt;&lt;/li&gt; --&gt; &lt;/ul&gt; </code></pre> <p>Current JQuery/JavaScript:</p> <pre><code>var percentage = 0; function updateBar() { percentage += 25; $('.ui-progressbar-value').stop().animate({ width: percentage+"%" }, 500) $('.middle').progressbar('option','value', percentage); if(percentage &gt; 100) { $('ui-progressbar-value').stop().animate({ width: "100%"}, 500); } } $(function() { $('.middle').progressbar({ value: percentage, complete: function() { alert('The progress bar is full'); } }); </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.
