When you write your next application, try to consider the web browsers that do not have support for AJAX.
Note: When we say that a browser does not support AJAX, it simply means that the web browser does not support the creation of a JavaScript object.

Writing Browser Specific Code
The easiest way to make your source code compatible with a browser is to make use of a try....catch blocks in your JavaScript.
<html> <body> <script language = "javascript" type = "text/javascript"> <!-- //Browser Support Code function ajaxFunction() { var ajaxRequest; // The variable that makes Ajax possible! try { // Opera 8.0+, Firefox, Safari ajaxRequest = new XMLHttpRequest(); } catch (e) { // Internet Explorer Browsers try { ajaxRequest = new ActiveXObject("Msxml2.XMLHTTP"); } catch (e) { try { ajaxRequest = new ActiveXObject("Microsoft.XMLHTTP"); } catch (e) { // Something went wrong alert("Your browser broke!"); return false; } } } } //--> </script> <form name = 'myForm'> Name: <input type = 'text' name = 'username' /> <br /> Time: <input type = 'text' name = 'time' /> </form> </body> </html>

In the above JavaScript code, we tried three times to make our XMLHttpRequest object. Our first attempt -
- ajaxRequest = new XMLHttpRequest.
It is specifically for Opera 8.0+, Firefox, and Safari web browsers. If it fails, then we try two more times to make the correct object for an Internet Explorer browser with -
- ajaxRequest = new ActiveXObject("Msxml2.XMLHTTP");
- ajaxRequest = new ActiveXObject(Microsoft.XMLHTTP");
If it doesn't work, then we can go for a very outdated web browser that doesn't support XMLHttpRequest, which also means that it does not support AJAX.
Most likely, our variable ajaxRequest will now be set to whatever XMLHttpRequest standard the browser uses and we can start sending data to the server.
