Try this:

<script type="text/javascript">
function getHeightFromString(str) {
  var parts = str.split(/height/).slice(1,2).join('');
      parts = parts.substring(parts.indexOf('"')+1);
      parts = parts.substring(0, parts.indexOf('"'));
  return parts;
}

str = '<applet codebase ="." archive="twviewer.jar" code="com.easypano.tw.TWViewer.class" name="TWViewer" width="680" height="500" hspace="0" vspace="0"align="left">';
document.write("<p>[" + getHeightFromString(str) + "]</p>");
str = ' height    =   "600" ';
document.write("<p>[" + getHeightFromString(str) + "]</p>");
</script>
