why doesnt this select work on input type='file'

[dc dalton]

Ive used this code a hundred times but today I am working on a photo upload app that (of course) uses <input type='file'> ... and for the strangest reason it no longer works

document.getElementById(fileBoxesTwo[x]).select();

I know Im getting the ids right from the array because the validation is working but the select doesnt work at all and I have no js errors.

Can you NOT do a select on an input type='file' ??

Don't you mean focus()?

It's porbably not supported for security reasons.

No I wanted to use select to "highlight" the field ... see the problem is they can be uploading up 12 images at a time (this damn car thing Im working on) so I wanted to make sure they are sitting there staring at 12 inputs saying "OK, which one is it"

Maybe Ill just change the boxes background color!

IE4+, Netscape 7.0+, and Firefox support changing the background color of <input type="file">, but Opera 7.54 does not.
