    <p>Well, you could use the callback you get from your backend file. Try this instead.</p> <p><strong>EDIT:</strong> As Pendo mention below, you should use JSON when returning data from <code>2.php</code>. </p> <p><strong>Edited version</strong></p> <p><strong>Index.php</strong></p> <pre><code>&lt;script type="text/javascript"&gt; $(function(){ // EDIT $('#comment').hide(); $("#submit").click(function(){ var formvalue = $("#content").val(); $.ajax({ type: "POST", url: "2.php", data: 'content='+formvalue, dataType: 'json', // EDIT set dataType to json success: function(ret){ $("#content").val(''); if(ret['success']) { //Fade in $('#comment').html('Insert Success!').fadeIn(1000); //Fade Out setTimeout(function(){ $('#comment').html('').fadeOut(1000); },1500); }else{ // Fade in $('#comment').html('Insert Failed!').fadeIn(1000); // Fade out setTimeout(function(){ $('#comment').html('').fadeOut(1000); },1500); } } }); }); }); </code></pre> <p></p> <pre><code>&lt;textarea name="content" id="content" cols="30" rows="3"&gt;&lt;/textarea&gt; &lt;br /&gt; &lt;input type="button" id="submit" name="submit" value="Add comment" /&gt; &lt;div id="comment"&gt;&lt;/div&gt; </code></pre> <p><strong>2.php</strong></p> <pre><code>&lt;?php $connection = mysql_connect('localhost', 'root' , 'root') or die(mysql_error()); $selection = mysql_select_db('my_content', $connection); $content = $_POST['content']; /* Set return data to false as default */ $json_ret = array('success'=&gt;false); $sql = "INSERT INTO msg (content) VALUES ('".$content."')"; if(mysql_query($sql)) { /* insert success.. add true */ $json_ret['success'] = true; } echo json_encode($json_ret); ?&gt; </code></pre>

    1. COThanks, @user741991, @PENDO, but I still want `insert success` with a `fadein` - `fadeout` effection. such as, when the date first insert, display `insert success`, then 1 seconds later, `insert success` moved from `div#comment`.

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.

SQuiL has stopped working due to an internal error.

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