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选为数组，即数组[1,2,3,5]

请提前指导谢谢

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);

所以，你几乎可以利用javascript的map函数来管理一种格式的数据，并将其转换为另一个数组，并从原始数组中提取数据。

您可以在$scope：

处推送到空数组

$scope.arrSportData = data.sportdata;
$scope.newArr = [];

angular.forEach($scope.arrSportData, function(value, key){
     $scope.associatedSportplayer = value;
     $scope.newArr.push($scope.associatedSportplayer.sport_id);
});

Answer 3

这可能会帮助您将sport_id放入数组中。

 var tempArr = []; 
   angular.forEach($scope.arrSportData, function(value, key){
       tempArr.push(value.sport_id);
   });

试试这段代码。

var app = angular.module('plunker', []);

app.controller('MainCtrl', function($scope) {

$scope.arrSportData = [ { 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"}];
  $scope.sportId = [];
angular.forEach($scope.arrSportData, function(value, key){
             $scope.associatedSportplayer = value;
         $scope.sportId.push($scope.associatedSportplayer.sport_id);
  
  });
  console.log($scope.sportId);
});

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>

  <body ng-app="plunker" ng-controller="MainCtrl">
    
  </body>

我不确切知道你需要它的位置，但这是一般的想法......

$scope.arrSportData = data.sportdata;
$scope.arrSportID = [];
    angular.forEach($scope.arrSportData, function(value, key){
        $scope.arrSportID.push(value.id);
    }

console.log($scope.arrSportID);

您需要将值存储在对象中，然后将其推送到数组。

$scope.item = {};  
  $scope.addItem = function() {   
      var newItem ={};   
      newItem.name= $scope.item.name;   
      newItem.title=$scope.item.title; 

   $scope.contact.items.push(newItem); 
   console.log( $scope.contact.items); 
  }
