you able fetch id of check box na.now compare id's of book check box id , find position.now discount percentage[position]
ex:

<script> var id = event.target.id; var position; var length = percentage.length(); for(var i=0;i<length;i++){ if( id == cardtypeid[i]){ position = i; break; } } var percen = percentage[position]; </script>
