IE autocomplete and default button bind

[bc]

Hi,
Is it possible to detect if the IE autocomplete function in a current
context such as a textbox is activated (ie. dropdown with previously
entered info is visible)?

Problem:
I use a script as a basis for binding <enter> in textbox to a button,
BUT <enter> in the dropdown autocomplete generated by IE also triggers
this event.
The script is available below (in .NET context but the idea should
shine through).

Best regards
Brian Christensen

Doesn't anybody have an idea on where to proceed? If there are
alternate groups that might be able to help me out I'd appreciate if
someone post them..

Thanks...

If you want to turn off IE's autocomplete feature, add
autocomplete="off" attribute to the input field that you want to use.

Tnx for suggestion! But I don't want to hack the solution by disabling
functionality, e.g by putting autocomplete="off" on my control, but
instead detect it. Can it be done via javascript?

The best I was able to do was detect if autocomplete was disabled.

In IE 6 at least document.getElementById('name_input').autocomplete
will return "off" if the name_input element contains
autocomplete="off".

If autocomplete isn't disabled then
document.getElementById('name_input').autocomplete just returns
undefined. Maybe you could use that as a basis of some detection code.

Note that in Firefox document.getElementById('name_input').autocomplete
always returns undefined.
