Having a given string, how to put the first letter of each word in large letters (Uppercase)?
For example:
original: 'a música é universal' High: 'A Música É Universal'
but also names like "anna-karin" common in the Nordic countries. In this case, it should be "Anna-Karin" .
Is there a solution for all languages?
The solution I found, which works for most accents in Latin and German languages, was with regex:
string.replace(/([^A-zÀ-ú]?)([A-zÀ-ú]+)/g, function(match, separator, word){
return separator + word.charAt(0).toUpperCase() + word.slice(1);
});
In regex I try to find a character not present in this list [A-zÀ-ú] (optional, hence the ? ) and a word of one or more letters with [A-zÀ-ú]+ , both with capturing group to be able to work within the replace function.
Example:
String.prototype.capitalize = function(){
return String(this).replace(/([^A-zÀ-ú]?)([A-zÀ-ú]+)/g, function(match, separator, word){
return separator + word.charAt(0).toUpperCase() + word.slice(1);
});
}
alert('a anna-karin gosta de música!'.capitalize());Another possibility, created by PHP.JS staff based on PHP ucwords () function:
