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>

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


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

function loadXMLDoc()
.... AJAX script goes here ...
