    copied!<p>I am trying to render an element and refresh it. So, when a user clicks a button, it calls an ajax function that calls a php function. this function adds data to a database. This all works. But, now I want to re-render the element with the new data. This is what I have so far:</p> <pre><code>public function add_role() { $this-&gt;autoRender = false; if ($this-&gt;request-&gt;data['Role']) { $this-&gt;Role-&gt;create(); if ($this-&gt;Role-&gt;save($this-&gt;request-&gt;data)) { $this-&gt;set('roles', $this-&gt;Role-&gt;find('all')); $this-&gt;render('/Elements/role_table'); }else{ return "Failed Insert"; } } } </code></pre> <p>But this causes the element to just be displayed twice in the page (although the new one is updated). How do I do this correctly or remove the original element?</p> <p>Thanks</p> <p>Edit: added element and jQuery</p> <p>Element:</p> <pre><code>&lt;?php echo' &lt;div style="overflow-y: auto; overflow-x: none; height: 100%; width:350px;" id="roleTable"&gt; &lt;table style=" border:1px solid black; width:300px; "&gt; &lt;tr&gt; &lt;th&gt;Id&lt;/th&gt; &lt;th&gt;Role&lt;/th&gt; &lt;/tr&gt; '; foreach ($roles as $role) { echo ' &lt;tr&gt; &lt;td&gt;'; echo $role["Role"]["id"]; echo ' &lt;/td&gt; &lt;td&gt;'; echo $role["Role"]["role_name"]; echo' &lt;/td&gt; &lt;/tr&gt;'; } echo' &lt;tr&gt; &lt;td colspan="2" style="border-top: 1px solid black;"&gt; Add Role: &lt;/td&gt; &lt;/tr&gt; &lt;tr&gt; &lt;td colspan="2"&gt; &lt;form id="ajaxPostForm"&gt; &lt;input type="text" name="data[Role][role_name]" style="width: 60%" required="required" id="tbRole" &gt; &lt;input value="Save" type="button" onclick="save_role();"&gt; &lt;/form&gt; &lt;/td&gt; &lt;/tr&gt; &lt;tr&gt; &lt;td colspan="2"&gt; &lt;div id="addRoleStatus"&gt; &lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt;&lt;/div&gt;'; </code></pre> <p>jQuery for original insert:</p> <pre><code>function save_role() { var role= $('#tbRole').val(); var base=$('#ajaxPostForm'); var params=base.serialize(); $.ajax({ type: 'POST', url: 'Roles/add_role', data: params, cache: false, dataType: 'HTML', beforeSend: function(){ }, success: function (html){ $('#addRoleStatus').html(html); }, error: function(XMLHttpRequest, textStatus, errorThrown) { alert("Status: " + textStatus); alert("Error: " + errorThrown); } }); } </code></pre>
