    <p>Ok, I have now a big headache and trying to solve this for a few days but no success. I have an Ajax function that is within the setInterval and pulls in a new data from database every 2 seconds.</p> <p>The Ajax creates a 'div' with the dynamic data coming from database as some numbers. Now, what i would like to implement is that when the new data is pulled or the text or value in DOM changes I want that particular div to do some animation.</p> <p>Let's say it will change the background color to red and then reverse to the default color or the div border will flickr for three times, etc.. Somehow I cannot get this work. And i tried different Event listeners but no luck.</p> <p>Here's my code for Ajax:</p> <pre><code>$(document).ready(function () { //function the get data from database function getRealData() { $.ajax({ url: 'test_api.php', data: "", dataType: 'json', success: function (rows) { var text = ''; var text2 = ''; for (var i in rows) { var row = rows[i]; var timeRespons = row[4]; text+= '&lt;div class="square"&gt;&lt;h4&gt;Time Response: '+ timeRespons+'&lt;/h4&gt;'; text += '&lt;/div&gt;'; } $("#journey").html(text); } }); } //this refreshes data every 2seconds setInterval(getRealData, 2000); //call the function to display data getRealData(); }); </code></pre> <p>and here's the output:<img src="https://i.stack.imgur.com/c2vHq.png" alt="enter image description here"></p> <p>So let's say if the time response change, then make the background red for 2 seconds and then reverse it back. Many thanks for your help :)</p>

    1. COWell, you are already creating the new div inside the ajax.success callback and that is the perfect place to check for any conditions for your animation. If you decided that you should animate just apply the animation to the div you just created.

    2. COYes, but my Ajax function is constantly creating the div. So your solution would always animate the div even though there is no change in the value. I would like to animate the div only if the value has changed otherwise no animation.

    3. CONo my solution wouldn't always animate the div. Like I said "... ajax.success callback is the perfect place **to check** for any **conditions** for your animation. **If you decide that you should animate** just apply the animation to the div you just created".

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.
