코드가 이렇게 되어 있는데....

필드늘어나는게 싫어서 wr_318이후는 빨간색 부분처럼 분할로 해보려니 잘 안되는군요,,

어떻게 해야 할까요? 도움이 필요해요

var wfm = document.fwrite; var chi_price; var ko_price; function get_inputName(id){      if(id == 'wr_313'){ chi_price = wfm.wr_63; ko_price = wfm.wr_307; }      else if(id == 'wr_314'){  chi_price = wfm.wr_64; ko_price = wfm.wr_308; }      else if(id == 'wr_315'){  chi_price = wfm.wr_65; ko_price = wfm.wr_309; }      else if(id == 'wr_316'){  chi_price = wfm.wr_66; ko_price = wfm.wr_310; }      else if(id == 'wr_317'){  chi_price = wfm.wr_67; ko_price = wfm.wr_311;}      else if(id == 'wr_318'){  chi_price = wfm.wr_68; ko_price = wfm.wr_312;}                  else if(id == 'weight6'){  chi_price = wfm.cny[$i]; ko_price = wfm.krw[$i];}      else if(id == 'weight7'){  chi_price = wfm.cny[$i]; ko_price = wfm.krw[$i];}      else if(id == 'weight8'){  chi_price = wfm.cny[$i]; ko_price = wfm.krw[$i];}           }

function calc_deli_price(exp){        type = 'ems';     disc = $('#cal_disc_ems').val();      var param = 'exp=' + exp + '&type=' + type + '&disc=' + disc;      $.post(board_skin_url + '/cal_delivery_cost.php', param, function(req){        if(req.result != 'success'){ alert('Error'); return;}       else{           deliv_price = 1* req.data + 15;             chi_price.value = deliv_price;           exch_price = Math.round(exch_rate * deliv_price);             ko_price.value = exch_price;       }    }, "json");

}
