I need to enter customers by name to form field (input type=text):

1. User will type some first letters of customer name

2. If an attempt is move out from name field, a call to Webserver is made Sample of such call is at www.ashleyit.com/rs/rscookie.txt.
This call returns 30 matching customer names and customer IDs . Those names are displayed to
user in separate pop-up window. If user makes selection,
field contents should be replaced by customer name. Selected Customer ID must be saved to hidden form field.

3. If no match, an error message should be displayed and name field
will not lose focus.

Are there any samples how to implement this using Internet Explorer in client side ?
