howto hidding/overriding history dropdown list of a textbox ?

[didier Belot]

Hi!

If the subject isn't clear:

Modern browsers provide an optional way of remembering user input in
textbox: user begin to type, and a list drop down just under the
textbox showing matching strings already typed.

I just want to provide my own droplist.

Is there an already existing component/script somewhere, and if not,
is there a way of either:
- place some div that cover that builtin list
- feed the builtins list with my own values

Thanks for any help or pointers.

Then instead of a text input, use a select element.

See above.

No.

No.

Yes. There is a good example, the nearest of what I want, at evolt.com:

The problem with only a select is: the list can't be populated before
the user type in some chars; it's about the classical "suggest as you
type" ported to the web, with a distant MySQL server : we don't want to
load a select with 10000+ records, but as soon as we have 3/4 letters,
we can load a smaller list (using either xmlrpc or the iframe technique)
and begin offering suggestions to user...

(...)

No.

last attempt ;-) : disable that builtin list ?
(I guess the answer is... no)

Anyway, thanks for yous answer.

You could get rid of the built-in list by randomly generating the field
name...

And in the process, make it 100 times harder (if not more) to retrieve
the form fields when the form is submitted. Thats a bit like shooting
your foot off to get a splinter out of your toe

If the list is that extensive, then you may want to look into breaking
it down into categories then. Maybe even a dependent select element
situation where the 4th (or so) depends on the 3rd depends on the 2nd
depends on the 1st. And yes, with some solid planning, it could be
implemented without a JS dependency.

You guessed right Its a user preference and js can't override user
preferences (thankfully).

Other than what was suggested in another reply, of giving that text
field a random name. Use the onchange event handler to populate the
actual field before submission. Then you have introduced a needless
dependency on JS and annoyed your users that have the prefs set to show
that list

Anyway, thanks for yous answer.

Welcome.
