Bug 13690 – JavaScript Form Validation issue on Banco do Brasil site

• Status: RESOLVED
• Resolution: FIXED
• Component: Forms

[Rodrigo Recio]

The form field don't validate as expected, in other browsers like firefox it works fine!

Is it possible to verify this issue without having an account in this bank? Could you please provide detailed steps to reproduce?

Most importantly, does this happen with nightly WebKit builds? You can get one from <http://nightly.webkit.org>.

[Rodrigo Recio]

Yes, that's it.. go to the URL above and and try to fill numbers in "Agência" and "Conta" fields, if you type 12345 it should appear 1234-5 (like in other browsers), but in webkit it shows 12345-, and in "Conta" field if you try to use backspace (to delete 12345) it will delete 1234 (not 5). Sorry about the lack of instructions.

Well, this happened with yesterday's nightly build, I see that is a new one this morning! :) 

[Alexey Proskuryakov]

Confirmed with r21427 nightly. Thank you for the additional information!

proposed fix

The behavior of setValue for active text input fields didn't match other browsers, and it has actually regressed for inactive fields (the latter problem didn't affect this particular site, though).

+            cachedSelStart = cachedSelEnd = max;

We normally try to stay away from these multiple assignment statements.
