Hi all, how are you today? This article explains how to load data on demand or load data when the user scrolls. Here we will do this in a simple manner, I hope you enjoy it.

Background

A few days ago one of my colleagues asked me how to load data into the UL when we do scroll. I could help him on that time itself. But here I am writing this article for his future reference. In this way we can do this very easily.

Using the code

Since we will load the data on a scroll, we need to fire the window events. So I suggest include a jQuery plugin in your page as in the following:
[js]
<script src=“jquery-2.1.4.min.js”></script>
[/js]

Once you are done, you are ready to go!

Our next step is load some initial or static data.
[html]
<div id=“myScroll”>
<p>
Contents will load here!!!.<br />

</div>
[/html]

Now we need some styles, right?

[css]
<style>
#myScroll {
border: 1px solid #999;
}
p {
border: 1px solid #ccc;
padding: 5px;
text-align: center;
}
.loading {
color: red;
}
.dynamic {
background-color:#ccc;
color:#000;
}
</style>
[/css]

What is next? Shall we run it and see our page now?

So now we have loaded the static data. Now it is time to fire the scroll event.
[js]
$(window).scroll(function () {
if ($(window).scrollTop() == $(document).height() – $(window).height()) {
appendData();
}
});
[/js]

In the preceding code, I am calling the scroll event and when the condition $(window).scrollTop() == $(document).height() – $(window).height() is satisfied, I am calling a function. You can see the function below.
[js]
function appendData() {
var html = ”;
for (i = 0; i < 10; i++) {
html += ‘<p class=”dynamic”>Dynamic Data : Life treats you in the same way, how you treat your life.Follow your passion, be prepared, do not let anyone limit your dreams. My Passion towards my life !!! – See more at:<a href=”http://sibeeshpassion.com/”>http://sibeeshpassion.com/</a> </p>’;
}
$(‘#myScroll’).append(html);
}
[/js]

Here I am populating 10 records dynamically and appending the created data to our main element. Once you are done, you can see the output as in the following.
