JavaScript - Handles encoding and decoding of HTML entities

htmlEntities.js

htmlEntities = {
  // encode special characters to html encoded characters
  encode: function (text) {
    var encodedString = '';
    for (i = 0; i < text.length; i++) {
      if (text.charCodeAt(i) > 127) {
        encodedString += '&#' + text.charCodeAt(i) + ';';
      } else {
        encodedString += text.charAt(i);
      }
    }

    return encodedString;
  },

  // decode html encoded characters to original characters
  decode: function (text) {
    return text.replace(/&#(\d+);/g, function (match, dec) {
      return String.fromCharCode(dec);
    });
  }
};
