Populating the Combo Box using AJAX

[Aravind Prasad]

Dear Ranchers,
I'm doing my project in JSP and MySQL. The project is a lead-time calculation part. In the page I designed, I've 5 combo boxes.

Combo 1 : List all the countries
Combo 2 : List the Ports in the country which i selected after reloading
Combo 3 : List the Destination Place from the Lead time after reloading
Combo 4 : List the details type of transportaion (AIR, SEA or Road)

Textbox : will display the lead time of the shipments coming in mode of transport where country = xxx and port = xxx and destination = xxx

When ever i change the combo box values, I've written a script in onChange() to submit to the same page and it is taking long time for the user, since it is uploaded in the remote server.

I would like to use this in AJAX. I want some sample code for doing this.

Please help me ranchers..

Thanks and Regards

There are examples of doing this all over the web. What part has you stumped?
