    <p>I have been trying to learn ajax and from what I can see my code is correct however it always refreshes the page when it echo's the returned json string. Any help would be greatly appreciated!</p> <pre><code> &lt;script&gt; // Get XML HTTP Type function get_XmlHttp() { var xmlHttp = null; if(window.XMLHttpRequest) { xmlHttp = new XMLHttpRequest(); }else if(window.ActiveXObject) { xmlHttp = new ActiveXObject("Microsoft.XMLHTTP"); } return xmlHttp; } function ajaxSuccess () { alert(this.responseText); } function ajaxrequest(oFormElement) { //Get The Correct XMLHTTP Object var request = new XMLHttpRequest(); request.open(oFormElement.method, oFormElement.action, true); request.setRequestHeader("Content-type","application/x-www-form-urlencoded"); request.send(new FormData(oFormElement)); return false; request.onreadystatechange = function() { if (request.readyState == 4 &amp;&amp; request.status == 200) { alert("done"); document.getElementById('comment_form').innerHTML = request.responseText; } } } &lt;/script&gt; &lt;form action="&lt;?php echo $add_comment; ?&gt;" method="post" enctype="multipart/form-data" id="comment_form" onsubmit="ajaxrequest(this);"&gt; &lt;input name="user_id" type="hidden" value="&lt;?php echo $user_id; ?&gt;"&gt; &lt;input name="user_message_id" type="hidden" value="&lt;?php echo $user_message_id; ?&gt;"&gt; &lt;textarea id="new_comment" name="new_comment" cols="100" rows="5"&gt;&lt;/textarea&gt; &lt;input type="submit" value="post request"/&gt; &lt;/form&gt; </code></pre>

    1. COI could be going blind, but where is the `submitForm()` function ?

    2. COI have actually tried it two ways one as in the example with the submit button and one with a link "<a onclick="submitForm(document.forms['comment_form']);" class="button"><?php echo $button_add_comment; ?></a>"

    3. COThe problem is that your function does nothing to prevent the default action of the form submit button.

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).
