Little javascript method to get initials from a name

stringUtils.js

String.prototype.getInitials = function(glue){
    if (typeof glue == "undefined") {
        var glue = true;
    }

    var initials = this.replace(/[^a-zA-Z- ]/g, "").match(/\b\w/g);
    
    if (glue) {
        return initials.join('');
    }

    return  initials;
};

String.prototype.capitalize = function(){
    return this.toLowerCase().replace( /\b\w/g, function (m) {
        return m.toUpperCase();
    });
};

To use it, very simple, include this javascript anywhere you want (but before calling it), then:

"Tommy Lee Jones".getInitials();

It will return TLJ.

If you prefer to get an array of initials, call "Tommy Lee Jones".getInitials(false);, then it will return an array.

Currently, due to JS regex limitations, it doesn't support well special chars. So it removes special chars to avoid wrong initials.
