lower case conversion in replace function

[Claude Schneegans]

Hi,

I'trying to use a regExp in Javascript to replace any all upper case word in a string by the same word having only its first letter in upper case.
This expression detects the words:
/([A-ZÄÀÉÈÊËÎÏÔÙÛÜ])([A-ZÄÀÉÈÊËÎÏÔÙÛÜ]+)/g
and backreferences $1 and $2 will contain the first letter and the rest of the word respectively.

Now, how can I convert $2 to lower case in the replace function?
I would need something like:
replace(/([A-ZÄÀÉÈÊËÎÏÔÙÛÜ])([A-ZÄÀÉÈÊËÎÏÔÙÛÜ]+)/g, "$1" + "$2".toLowerCas e())
But this does not work since the toLowerCase() is applied first to the string "$2", THEN the string $2 is replaced by the second match.

Try:

var s = "ABCDE FGHI";
s = s.replace(
/([A-ZÄÀÉÈÊËÎÏÔÙÛÜ]+)/g,
function (w) {
return w.charAt(0).toU pperCase() +
w.substring(1). toLowerCase();
}
);
alert(s);

Is so! :P

Javascript identifiers may contains the letters (a-z, any case),
digits (0-9), underscore (_) and dollar sign ($). The first character
may not be a digit. Read ECMA 262, section 7.6.

The $ is *intended* for mechanically generated code, but there is no
requirements.
