    copied!<p>First, you should use the jQuery <code>addClass()</code> method. You don't need to write your own (your addClass() implementation is buggy, by the way).</p> <p>Try this:</p> <pre><code>function selectInList(obj) { $("#circularMenu").children("a").removeClass("highlight"); $(obj).addClass("highlight"); } </code></pre> <p>Then:</p> <pre><code> &lt;ul id="circularMenu"&gt; &lt;a href="#strategy" onclick="selectInList(this);"&gt;&lt;li id="strategy_link"&gt;&lt;h3&gt;Strategy&lt;/h3&gt;&lt;/li&gt;&lt;/a&gt; &lt;a href="#branding"&gt;&lt;li id="branding_link" onclick="selectInList(this);"&gt;&lt;h3&gt;Branding&lt;/h3&gt;&lt;/li&gt;&lt;/a&gt; &lt;a href="#marketing"&gt;&lt;li id="marketing_link" onclick="selectInList(this);"&gt;&lt;h3&gt;Marketing&lt;/h3&gt;&lt;/li&gt;&lt;/a&gt; &lt;a href="#media"&gt;&lt;li id="media_link" onclick="selectInList(this);"&gt;&lt;h3&gt;Media&lt;/h3&gt;&lt;/li&gt;&lt;/a&gt; &lt;a href="#management"&gt; &lt;li id="management_link" onclick="selectInList(this);"&gt;&lt;h3&gt;Management&lt;/h3&gt;&lt;/li&gt;&lt;/a&gt; &lt;/ul&gt; </code></pre> <p>Or even better, keep your html clean and let jQuery simplify things:</p> <pre><code> &lt;ul id="circularMenu"&gt; &lt;a href="#strategy"&gt;&lt;li id="strategy_link"&gt;&lt;h3&gt;Strategy&lt;/h3&gt;&lt;/li&gt;&lt;/a&gt; &lt;a href="#branding"&gt;&lt;li id="branding_link"&gt;&lt;h3&gt;Branding&lt;/h3&gt;&lt;/li&gt;&lt;/a&gt; &lt;a href="#marketing"&gt;&lt;li id="marketing_link"&gt;&lt;h3&gt;Marketing&lt;/h3&gt;&lt;/li&gt;&lt;/a&gt; &lt;a href="#media"&gt;&lt;li id="media_link"&gt;&lt;h3&gt;Media&lt;/h3&gt;&lt;/li&gt;&lt;/a&gt; &lt;a href="#management"&gt;&lt;li id="management_link"&gt;&lt;h3&gt;Management&lt;/h3&gt;&lt;/li&gt;&lt;/a&gt; &lt;/ul&gt; </code></pre> <p>Then, somewhere in your page:</p> <pre><code>$(document).ready(function() { $("#circularMenu").children("a").click(function() { selectInList(this) }); }); </code></pre>
