Jumpseller Checkout: Connect Payment Method to Shipping method.liquid

<script>  
    var payment_method_id 	= '289171';
    var shipping_method_id 	= '258168';
  
  function cashOnDelivery(){
    if($("#payments_options input:checked").val() == payment_method_id){
      $.each($('#shipping_options input'), function(index, element){ 
        element = $(element)
        if(element.val() != shipping_method_id){
          element.parent().hide()
        }else{
          element.parent().show()
          $('#shipping_options input[value='+shipping_method_id+']').click(); 
        }
      } )
    }else{
      $.each($('#shipping_options input'), function(index, element){ 
        element = $(element)
        if(element.val() != shipping_method_id){
          element.parent().show()
          $('#shipping_options input[value='+$(this).val()+']').click();
        }else{
          element.parent().hide()
        } 
      } )
    }
  };
$(document).ready(cashOnDelivery);
$("#payments_options").click(cashOnDelivery);
</script>

instead of 112994 it's more clear to have:

var payment_method_id = '112994'

and later replace that with a Theme Option.
