parseUrl.js

function parseUrl(url) {
  var urlRegex = /^(?:([A-Za-z]+):)?(\/{0,3})([0-9.\-A-Za-z]+)(?::(\d+))?(?:\/([^?#]*))?(?:\?([^#]*))?(?:#(.*))?$/;
  
  var result = urlRegex.exec(url);
  return {
    href: result[0], protocol: result[1], slashes: result[2],
    hostname: result[3], port: result[4], pathname: result[5],
    query: result[6], hash: result[7]};
}
