AJAX Example


To understand how AJAX works, we will create a small AJAX application:

Example

Let AJAX change this text


Try it yourself »


AJAX Example Explained

The AJAX application above contains one div section and one button.

The div section will be used to display information returned from a server. The button calls a function named loadXMLDoc(), if it is clicked:

<!DOCTYPE html>
<html>
<body>

<div id="myDiv"><h2>Let AJAX change this text</h2></div>
<button type="button" onclick="loadXMLDoc()">Change Content</button>

</body>
</html>

Next, add a <script> tag to the page's head section. The script section contains the loadXMLDoc() function:

<head>
<script>
function loadXMLDoc()
{
.... AJAX script goes here ...
}
</script>
</head>

The next chapters will explain how AJAX works.
