First AJAX Application

First AJAX Application

So let’s begin by taking up an example. Create a simple HTML page myAJAX.html as shown below


<form name="myAJAXForm">
Name: <input type="text" name="name" />
Current Date: <input type="text" name="time" />


This HTML page has a two textboxes – one where user will enter his name and the other one displays current date. We will request date data directly from the web server.

Now create a php page date.php which prints out the current date

echo(date("D F d Y",$t));

Once you have done this now we need to add additional code to our HTML page to be able to use AJAX.

<script type="text/javascript">
function setupAJAX()
var xmlhttp;
if (window.XMLHttpRequest)
  // code for IE7+, Firefox, Chrome, Opera, Safari
  xmlhttp=new XMLHttpRequest();
else if (window.ActiveXObject)
  // code for IE6, IE5
  xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
  alert("Sorry, your browser seems to not support XMLHTTP functionality.");

The above code checks to whether the user’s browser supports XMLHTTP or not.
