Question

我有三个输入，我在两个输入中减去值并在结果输入中结合结果。但我想在按钮点击上添加新行，我尝试在tr中重复使用但不能正常工作

var ReceiptsApp = angular.module('ReceiptsApp', []);

ReceiptsApp.controller('ReceiptsController', function ($scope) {
 $scope.rvm = [{}];
   $scope.addRow1 = function (index) {
        //alert('ss');
       $scope.result = $scope.r.val1 - $scope.r.val2;
        if ($scope.rvm.length == (index + 1)) {
            $scope.rvm.push({
            });
        }

    }


});

ReceiptsApp.controller('ReceiptsController', function ($scope) {
 $scope.rvm = [{}];
   $scope.addRow1 = function (index, r) {
        // pass the particular array object on which you want to perform calculations when the function is called from ng-click and access those particular objects values using r.val1 and r.val2
        //Access particular "rvm" object using index
        $scope.rvm[index].result = r.val1 - r.val2;
        if ($scope.rvm.length == (index + 1)) {
            $scope.rvm.push({
            });
        }

    }

在HTML中

<td>
   <input type="text" lass="input-large" ng-model="r.result" name="res" />
  </td>
 <td>
  <button type="button" class="btn btn-default" ng-click="addRow1($index, r)">Add</button>
 </td>
