Replace from all words, even if seperated with dash, first character with uppercase [more simple way]

I got it working, all variations are displayed Sint-Anna as should be, but I wonder, is there a more simple way to this, since it looks very cluttered?

String.prototype.capitalize = function(){
    var sa = this.replace(/-/g,' ');
    var saa = sa.toLowerCase();
    var sb = saa.replace( /(^|\s)([a-z])/g , function(m,p1,p2){ return p1+p2.toUpperCase(); } );
    var sc = sb.replace(/\s+/g, '-');
    return sc;
};

console.log('sint-anna'.capitalize());
console.log('sint anna'.capitalize());
console.log('sint-Anna'.capitalize());
console.log('Sint Anna'.capitalize());
console.log('SiNt anna'.capitalize());
console.log('SINT ANNA'.capitalize());

Console:

Sint-Anna
Sint-Anna
Sint-Anna
Sint-Anna
Sint-Anna
Sint-Anna

There are no ways that there is a wrong input like Si ntAn na resulting in Si-Ntan-Na.

String.prototype.capitalize = function(){
   this.split('-').map(function(str){
      return str[0].toUpperCase() + str.substr(1).toLowerCase();
   }).join("-")  
};

The above would be more succinct I suppose. It splits on - and then maps, which captializes first letter and lower cases the others and then joins with - using Array.join
