Javascript 如何通过数组更新角度子范围

我正在从服务器获取一组数据，并将更新angularJS中的

$scope

初始值为：

$scope.form = {};

我希望动态更新，如下所示：

$scope.form = {"firstname" : "Alex"};

sent.then(function(result) {
  angular.forEach(result.data.test, function(value, key){
    // ** something like this, but it doesn't work :
    var form_child = "{" + value.FieldName + ":" + value.FieldValue "}";
    $scope.form = form_child;
  });
});

firstname

和

alex

都必须通过如下数组进行更新：

$scope.form = {"firstname" : "Alex"};

sent.then(function(result) {
  angular.forEach(result.data.test, function(value, key){
    // ** something like this, but it doesn't work :
    var form_child = "{" + value.FieldName + ":" + value.FieldValue "}";
    $scope.form = form_child;
  });
});

如何执行第**行？

在angular中，您无权访问子作用域，只能访问父作用域。

使用数组语法：

$scope.form[value.FieldName] = value.FieldValue;
