Flex: Capitalize words in string?

Question

I am trying to do the equivalent of PHP's ucwords() in Flex. I dont want the whole string in uppercase just the first letter of each word. Does anyone know a way?

Thanks!

Answer 1

Try

str.replace(/\b./g,function(m){return String(m).toUpperCase()});

explanation:

the regex /\b./g matches a word boundary followed by any character. All matches will be passed to the anonymous function defined in second parameter of replace method. The function returns the match capitalized.

Answer 2

I made the following changes to get past some errors and warnings:

str.replace(/\b./g,function(m:String):String{return m.toUpperCase()});

but it gave me a strange crash, saying that it had three parameters when only one was expected.

I tried to fix the regex, but my regex-fu is not great. So I punted. This works (at least, for the first word in a string). For multiple words, you'd have to use the split.

str = str.substr(0,1).toUpperCase() + str.substr(1,str.length);

Answer 3

This is the same as Rafael's answer but with no warnings :)

str.replace(/\b./g,function(...m):String{return m[0].toUpperCase()});
