    copied!<p>I putting together a page that will display a set of stored values. I am using mootools and AJAX calls to update the values without needing to refresh the page each time the user selects a new item from the drop down menus.</p> <p>the HTML each line looks something like:</p> <pre><code>&lt;div class="selections"&gt; &lt;input class="checkbox selector" type="checkbox" CHECKED /&gt; &lt;span class="b_name"&gt; &lt;select class="b_n selector"&gt; &lt;!-- options --&gt; &lt;/select&gt; &lt;/span&gt; &lt;span class="b_level"&gt; &lt;select class="b_l selector"&gt; &lt;!-- options --&gt; &lt;/select&gt; &lt;/span&gt; &lt;span class="values"&gt; &lt;!-- the values --&gt; &lt;/span&gt; </code></pre> <p></p> <p>In the head I have set up an event listener like:</p> <pre><code> $$('.selector').addEvent('change', function(event){changeValues(this);}); </code></pre> <p>My problem is that when the "b_name" select changes I have to update the list of options in the "b_level" select. I accomplish that by getting a list of the possible options from my database through a php script on another page and replacing "b_level"'s innerHTML. Once I do that, the event listener attached to "b_l selector" no longer works.</p> <p>I tried to resolve this issue by explicitly attaching an event listener to "b_l selector" each time "b_name" changes like so:</p> <pre><code> row.getElement('.b_l').addEvent('change', function(event){changeValues(row.getElement('.b_l'));}); </code></pre> <p>where 'row' is the html element 'div.selections'.</p> <p>It still isn't working and I have no idea what's going on. Can anyone offer a suggestion as to how I can get this resolved? or perhaps a better way to do what I'm doing.</p> <p>Thanks</p>
