    <p>With the following jQuery code I have created a drop down that updates the page however I believe that when it changes <code>#content</code> with the returned result it is counting it as a <code>change</code> event and pulling the <code>#sidebar</code> info.</p> <pre><code>&lt;script&gt; var get_pages_load_options = { target: '#content', data: {ajaxtype: 'content'}, beforeSubmit: function() { console.debug('beforeSubmit'); }, success: function() { console.debug('successful'); } }; $("#content").on('change','.get_pages',function(){ var submit_page = $(this).attr('rel'); var form_url = $("#"+submit_page).attr('action'); console.debug(submit_page+" &amp; "+form_url); $("#"+submit_page).ajaxForm(get_pages_load_options); $.ajax({ type: "POST", url: form_url, data: {ajaxtype: "side"}, success: function(data) { console.debug(data); $("#sidebar_menu").html(data); } }); }); &lt;/script&gt; </code></pre> <p>The HTML is as follows for <code>#content</code>:</p> <pre><code>&lt;div id="content" class="content"&gt; &lt;h1&gt;Game Updates&lt;/h1&gt; &lt;form action="/gameplay/updates/" id="submit_page" name="submit_page" class="get_pages" method="post"&gt; &lt;select name="year" class="get_pages" rel="submit_page"&gt; &lt;option value="2012"&gt;2012 -- v1.7.0 - v2.0.0&lt;/option&gt; &lt;option value="2011"&gt;2011 -- v1.5.3 - v1.6.0&lt;/option&gt; &lt;option value="2010"&gt;2010 -- v1.3.3 - v1.5.2&lt;/option&gt; &lt;option value="2009"&gt;2009 -- v1.1.4 - v1.3.2&lt;/option&gt; &lt;option value="2008"&gt;2008 -- v0.6.0 - v1.1.3&lt;/option&gt; &lt;option value="2007"&gt;2007 -- v0.1.x - v0.5.5&lt;/option&gt; &lt;/select&gt; &lt;/form&gt; /** Update Logs **/ &lt;br/&gt;&lt;br/&gt; &lt;p&gt; -----------&lt;br /&gt; Thank you,&lt;br /&gt; Admin deth4uall &lt;/p&gt; &lt;/div&gt; </code></pre> <p>Do you know how I can prevent the second firing of change. Thanks!</p> <p>EDIT: I do have a regular version that is default with the above supposed to be overwriting the below functionality:</p> <pre><code>$("#content").on('change','.get_pages',function(){ var submit_page = $(this).attr('rel'); $("#"+submit_page).submit(); }); </code></pre>

    1. COif you are using jQuery 1.3.2+, replace livequery with live. If you are using jQuery 1.4+ replace it with http://api.jquery.com/delegate , and finally, if you are using jQuery 1.7+ replace it with http://api.jquery.com/on . Else, we'll have to look at the documentation for livequery.

    3. COAre you using the correct syntax for a `.on` delegated event? `$("#content").on("change",".get_pages",function(){...});`

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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
