javascript - Replace variables from the mathematical equation with array values using angularjs? -

i have equation following format

$(5)+$(6) 5 & 6 input ids.

each input id has @ least 100 values array. format follows

var data = [{id : 5, inputs :[{value:10},{value:10},{value:11},...,{value:12}]},{id : 6, inputs :[{value:10},{value:10},{value:11},...,{value:12}]}]; 

what want replace equation variables corresponding values data.

following current code

//tpl $(5)+$(6); $scope.value_replacer = function (tpl, data) {     var re = /\$\(([^\)]+)?\)/g, match;     var valuearray = [];     (var = 0; < data.length; i++) {         while (match = re.exec(tpl)) {             if (match[1] == data[i].id) {                 (var j = 0; j < data[i].inputs.length; j++) {                     tpl = tpl.replace(match[0], data[i].inputs[j].value);                     if (i == data.length - 1) {                         valuearray.push(tpl);                     }                 }                 re.lastindex = 0;             }         }     }     return valuearray; } 

if have 100 data values , resulting array should contain 100 values. getting same values. please me correct values?

update

my equation user defined ie equation may time $(5) - $(6) or $(5)*$(6) that.. want replace 5 , 6 (ie ids)

you can use 2 loops achieve this

var myapp = angular.module('myapp', []);  myapp.controller('ctrl', ['$scope', function($scope) {      $scope.data = [{          id: 5,          inputs: [{              value: 10          }, {              value: 10          }, {              value: 11          }, {              value: 12          }]      }, {          id: 6,          inputs: [{              value: 10          }, {              value: 10          }, {              value: 8          }, {              value: 12          }]      }];      (var = 0; < $scope.data.length; i++) {          sum = 0          (var j = 0; j < $scope.data[i].inputs.length; j++) {              sum += $scope.data[i].inputs[j].value;          }          $scope.data[i].sum = sum;      }      $scope.findind=function(id){       var index = $scope.data.findindex(x=>x.id === id);       return index;      }      $scope.multiply=function(){       var res = 1;       (var = 0; < arguments.length; i++) {          var idsum=$scope.findind(arguments[i]);          res *= parseint($scope.data[idsum].sum);       }       return res;      }      $scope.divide=function(){       var res =$scope.data[$scope.findind(arguments[0])].sum;       (var = 1; < arguments.length; i++) {          var idsum=$scope.findind(arguments[i]);          res /= parseint($scope.data[idsum].sum);       }       return res;       }      $scope.add=function(){       var res = 0;       (var = 0; < arguments.length; i++) {          var idsum=$scope.findind(arguments[i]);          res += parseint($scope.data[idsum].sum);       }       return res;      }      $scope.subtract=function(){       var res = 0;       (var = 0; < arguments.length; i++) {          var idsum=$scope.findind(arguments[i]);          res = parseint($scope.data[idsum].sum)-res;       }       return res;      }      console.log($scope.add(5,6));      console.log($scope.subtract(5,6));      console.log($scope.multiply(5,6));      console.log($scope.divide(5,6));  }]);
