get data from another page

[Robin]

now i have a text area, when user enter their ID (10 chars),
a script will use the id to use this ID to get the user data,
and fill the form automatically. how can i use javascript to get data
from anther page (JSP generated). as follow

STEP 1: user enter id,

ID: A123456789
NAME : _________
PHONE: _________
ADDR : _________

-> after enter the id (without submit)
-> a javascript will send a request to

http://localhost/getuser?id=A123456789

-> a response will contain the data, and a script will fill the form

==>

ID: A123456789
NAME : dick
PHONE: 123456
ADDR : somewhere

This can be done like this:

Your Page (ID field's onchange event) --submit--> jsp for data --submit-->
Your Page (again)

Your page should be a JSP, which do nothing on a GET request. The page
contains your HTML form, where the ID input field's onchange event will call
JavaScript to submit your form to the JSP page. Make a way so that JSP page
can redirect back to your page (e.g. pass URL along with ID), and in your
page when a POST request is received, retrieve posted data and fill them
into the form (via JavaScript).
