Population selectbox based on another select using ajax

Hi,

JSON is not a must to populate the selectbox based on another selectbox option.

I have developed a module and sharing with you all the module in text file.
It contains one ajax,one menu link and a function.

It is very simple and good for the drupal learners.

Please use it. contact me for any queries @ manniter006@gmail.com

Best Regards,
Have a happy drupal
