Javascript String camelize()

String.prototype.camelize = function() {
  var parts = this.split('-'), len = parts.length;
  if (len == 1) return parts[0];

  var camelized = this.charAt(0) == '-'
    ? parts[0].charAt(0).toUpperCase() + parts[0].substring(1)
    : parts[0];/*from  w w  w . ja va2s.com*/

  for (var i = 1; i < len; i++)
    camelized += parts[i].charAt(0).toUpperCase() + parts[i].substring(1);

  return camelized;

// TODO: Strip all but [a-zA-Z]

String.prototype.camelize = function () {
  return this.replace(/(?:^\w|[A-Z]|\b\w|\s+)/g, function (match, index) {
    if (+match === 0) {
      return '';
    }// or if (/\s+/.test(match)) for white spaces
    return index === 0 ? match.toLowerCase() : match.toUpperCase();
  });
};

// Extend String prototype
String.prototype.camelize = function camelize(){

    result += Math.random().toString(36).substr(2).substr(0, 10);
  }
  return result.substr(0, length);

 *  String#camelize() -> String
 *
 *  Converts a string separated by dashes into a camelCase equivalent. For
 *  instance, `'foo-bar'` would be converted to `'fooBar'`.
 *
 *  Prototype uses this internally for translating CSS properties into their
 *  DOM `style` property equivalents.
 *
 *  ##### Examples
 *
 *      'background-color'.camelize();
 *      // -> 'backgroundColor'
 *
 *      '-moz-binding'.camelize();
 *      // -> 'MozBinding'
