Js function to extract urls from text (with silly regexp)

detectUrls.js

var detectUrls = function(text) {
  var pattern = /(?:^|[\s\n\r])((?:https?:\/\/|www\.)[^\s\n\r]+)/ig,
      urls = [],
      matches;
  while ((matches = pattern.exec(text)) !== null) {
    urls.push(matches[1]);
  }
  return urls;
};
