AJAX implementation with drop down

HI

Currently into my application I perform a normal action for every drop down. For instance I have a page which has 5 drop down so it takes time for every consecutive action. So I am thinking to incorporate AJAX methodology for achieving it. Pls help me 开发者_开发技巧in doing so with an example.

Here's an example using jQuery:

This fills in the second drop-down with data from the server based on the selection in the first drop-down. There are comments to explain some of the jsFiddle specifics.
