让JW Player响应

My code

function get_signed_player($videokey,$playerkey) {
  $path = "players/".$videokey."-".$playerkey.".js";
  $expires = round((time()+3600)/300)*300;
  $secret = "xxxxxxxxxxxxxxxxxxxxx";
  $signature = md5($path.':'.$expires.':'.$secret);
  $url = 'http://cdn.jwplayer.com/'.$path.'?exp='.$expires.'&sig='.$signature;
  return $url;
};

echo "<p>Watch this cool video:</p>";
echo "<script type='text/javascript' src='".get_signed_player('xxxxxxx','xxxxxx')."' width=\"100%\"></script>";

It's working fine. But, it's coming in fixed width.

How can I make it full width and responsive?

Can you help, please
