Question

我正在开发angularjs中的web应用程序。我有一个foreach循环来遍历范围对象。下面是我的js代码。

$scope.details = [];
$scope.apply = function() {
    angular.forEach($scope.screenMap, function(value, key) {
        //$scope.details.push(value.scrn_id, value.Read, value.Write);
        $scope.details.push("ID", value.scrn_id);
        $scope.details.push("Read", value.Read);
        $scope.details.push("Write", value.Write);
    });
    console.log($scope.details);
}

循环后，我总共得到18个条目，共3次迭代。

我期待的是

  ID:1  Read:True  Write: False
  ID:2  Read:False  Write: True
  ID:3  Read:True  Write: False
  ID:4  Read:False  Write: True

我可以知道如何以上述格式获取数组吗？

Answer 1

您必须将值作为对象推送到数组才能实现此目的。

$scope.details = [];
        $scope.apply = function () {
            angular.forEach($scope.screenMap, function (value, key) {
                //$scope.details.push(value.scrn_id, value.Read, value.Write);
                $scope.details.push({"ID":value.scrn_id,"Read":value.Read,"Write":value.Write});
            });
            console.log($scope.details);
        }

试试此代码

$scope.details = [];
$scope.apply = function () {
    angular.forEach($scope.screenMap, function (value, key) {
        var obj = {
            "ID" : value.scrn_id,
            "Read" : value.Read,
            "Write" :  value.Write
        };
        $scope.details.push(obj);
    });
    console.log($scope.details);
}

将其作为对象推送

$scope.details = [];
        $scope.apply = function () {
            angular.forEach($scope.screenMap, function (value, key) {

                $scope.details.push({"ID": value.scrn_id,
                                    "Read": value.Read,
                                    "Write": value.Write});
            });
            console.log($scope.details);
        }

Answer 4

       angular.forEach($scope.screenMap, function (value, key) {

            $scope.details.push({
              "ID": value.scrn_id,
              "Read": value.Read,
              "Write", value.Write
            });
        });

Answer 5

你在一个循环中推动3次，一次两个物体。不要使用逗号来插入键值对（对象名：值）
javascript对象注释如下 var x = {“nameofhe Object1”：object value1， “nameofhe Object2”：对象value2 } 3 * 2 * 3 = 18，这些是单个条目。

创建一个javascript对象并推入$ scope.details

    $scope.details = [];
    $scope.apply = function () {
        angular.forEach($scope.screenMap, function (value, key) {
            //$scope.details.push(value.scrn_id, value.Read, value.Write);
            $scope.details.push({"ID": value.scrn_id,
                                 "Read": value.Read,
                                 "Write": value.Write});
        });
        console.log($scope.details);
    }
