Luk knap til Java

Ved ikke om den er lidt tricky men jeg har følgende script som jeg gerne vil have to knapper til en sluk og en tænd, er det muligt ???

          <script language=\"JavaScript1.2\">
  var snowsrc=\"picture/snow.gif\"

  var am, stx, sty;  // amplitude and step variables

  if (ns4up) {
    doc_width = self.innerWidth;
    doc_height = self.innerHeight;
