Lab - Ajax

1. Base it on the demo of JavaScript calling a server-side program in background.
2. You will get this working on student.computing.dcu.ie
3. Copy my HTML to a HTML file in your public_html.
4. Copy my JS to a JS file in your public_html.
5. The URL of your HTML file will be something like: https://student.computing.dcu.ie/~userid/file.html

6. Edit a new PHP file in your public_html. This will be the server-side program it calls.
7. The URL of your PHP program will be something like: https://student.computing.dcu.ie/~userid/prog.php

8. Change the JS from calling my PHP program on my server to calling your PHP program on student.computing.dcu.ie
   • Note in the JS how you should remove the "http://server" part of the URL. This is Same origin policy. (In fact, depending on browser, leaving "http://server" in may work, but only if same-origin.)

9. Your PHP program does something with the argument.
