    How can I exit the each function when the conditions was true once?

    This does not work:

      $$('.box div').each(function(e) {
 if(e.get('html') == '') {
    e.set('html', 'test');
    exit;
 }
  });

    Reset to default 14

    Use .some?

      $$('.box div').some(function(e) {
     if(e.get('html') == '') {
        e.set('html', 'test');
        return true;
     } else
        return false;
  });

    But probably you could just use

      arr = $$('.box div[html=""]');
  if (arr.length > 0)
     arr[0].set("html", "test");

    Just throw something and catch it higher:

    try {
  $$('.box div').each(function(e) {
    if(e.get('html') == '') {
      e.set('html', 'test');
      throw "break";
    }
  });
} catch (e) {
  if(e != "break") throw e;
}

    But using a bination of .every and .some would be a far better idea.
