How to trigger a server side code in JS w/o using open()?

[lcs01]

Experts,

I want to implement a web form like this:

Ask a user to enter his/her firstname & lastname, then create an ID for this user. The first choice would be first initial + lastname. But I should check it for the uniqueness before I populate this ID to the user. The uniqueness verification is certainly done on the server side. But I don't know how to trigger a server side code throught a javascript code without calling open().

Your help is highly appreciated.

This is done using AJAX. You may want to google it to see how it works.
