Avoid All Capital Letters in Guestbook

#1 July 20th, 2005, 02:13 PM

Hello!

People go to sign my guestbook and wrote all text in capital letters.
Did you know any script that shows an window alert when one types the
second capital letter?

Best regards,

Carlos

It shouldn't be that hard. Keep a global boolean variable that switches
to true on upper case and false otherwise (hint: bool_var = object.value
== object.value.toUpperCase()). If it's already true, then show a
warning. However, it would be better to check it all on submission (to
allow for initialisms, acronyms, emphasis, etc).

As usual, use JS for convenience only. Redundant checking must be
performed on the server side, if possible.

Perhaps?

This version only warns the user when "two consecutive capital letters" are
entered but allows them to continue entering characters. In some cases,
"two consecutive capital letters" may be allowed.

And what about acronyms?

The proper way to prevent people from writing only in uppercase
is a RegExp instead of an iterating function. For example:

if (/^([A-Z]{10,}[] -@^-`\{-~[]*)+$/.test(sInput))
{
alert("Don't CRY, baby! ;-)");
}

This matches uppercased text longer than nine letters [1],
optionally followed by any number of spaces and punctuation
characters.

But keep in mind that you can never solve problems on layer 9 technically.

that besides ROTFLBTCDICAJTTWADBSISWTRHITSBKABAYB :)
