javascript - 如何将数据存储到 AngularJS 数组中

Question

$scope.arrSportData = data.sportdata;

        angular.forEach($scope.arrSportData, function(value, key){
             $scope.associatedSportplayer = value;
         console.log($scope.associatedSportplayer);

        //getting reponse

        /*
        Object { id: "1", user_id: "2", sport_id: "1", position_id: "1"}
        Object { id: "2", user_id: "2", sport_id: "2", position_id: "6"}
        Object { id: "3", user_id: "2", sport_id: "3", position_id: "12"}
        Object { id: "4", user_id: "2", sport_id: "5", position_id: "20"}
        */  

        });

我想将 sport_id 放入数组，即数组 [1,2,3,5]

请提前指导谢谢

Answer 1

var datas = [{
  id: "1",
  user_id: "2",
  sport_id: "1",
  position_id: "1"
}, {
  id: "2",
  user_id: "2",
  sport_id: "2",
  position_id: "6"
}, {
  id: "3",
  user_id: "2",
  sport_id: "3",
  position_id: "12"
}, {
  id: "4",
  user_id: "2",
  sport_id: "5",
  position_id: "20"
}];

var sport_ids = datas.map(function(data) {
  return Number(data.sport_id)
});

alert(sport_ids);

因此，您几乎可以利用 javascript 的 map 函数以一种格式通过管道传输数据数组，然后使用从原始数组中提取的数据将其转换为另一个数组。
