Question

Greetings, I want to capitalize each word in a script, for this I have came up with a such method:

//Word Capitalization
function wordToUpper(val) {
        newVal = '';
        val = val.toLowerCase().split(' ');
        for(var c=0; c < val.length; c++) {
                newVal += val[c].substring(0,1).toUpperCase() + val[c].substring(1,val[c].length) + ' ';
        }
        return newVal;
}

Now it works for regular words starting after and emtpy char ” “.

However I also want to make sure it fails for such strings:

wordToUpper('hello my name is Hellnar.it doesnt work.') -> Hello My Name Is Hellnar.it Doesnt Work. “it” had to be capital.

wordToUpper('hello my name is (hellnar).') -> Hello My Name Is (hellnar). “Hellnar” had to capital.

Regards

Answer 1

The following will handle all Unicode letters, unlike any solution using \w, \b or [a-z] etc. Admittedly the regular expression is rather large. Character lists taken from Steve Levithan’s excellent XRegExp library.
