script for applying paragraph and character styles in illustrator

Just in the doc page 240. I just tweaked the sample here:

var main = function() {
  var doc;
  if ( app.documents.length > 0 && app.activeDocument.textFrames.length > 0 ) {
  // Create the color to apply to the words
  wordColor = new RGBColor();
  wordColor.red = 255;
  wordColor.green = 0;
  wordColor.blue = 255;
  // Set the value of the word to look for
  searchWord1 = "myContent";
  // Iterate through all words in the document
  // and color the words that match searchWord
  for ( i = 0; i < app.activeDocument.textFrames.length; i++ ) {
  textArt = activeDocument.textFrames;
  for ( j = 0; j < textArt.words.length; j++) {
  word = textArt.words;
  if ( word.contents == searchWord1 ) {
  //:word.filled = true;
  //word.fillColor = wordColor;
  app.activeDocument.characterStyles.getByName ( "myCharacterStyle" ).applyTo ( word );
  }
  }
  }
  }
}
var u;
main();
