在多对象数组中添加键值

Question

Array [ Object, Object, Object, Object ]

Object {
  id : 1,
  name : xyz,
  section : b
},{
  id : 2,
  name : abc,
  section : a
},

$scope.array = Array [ Object, Object, Object, Object ];

          angular.forEach$scope.array, function(value, key){
              $scope.array.push({
                'new_va' : 1
              })
          }

我如何为每个对象添加新的键值请指导我尝试了不同的方法但不起作用提前谢谢

Answer 1

这是我的解决方案：

$scope.array.forEach(function(obj, key){
    obj['new_va'] = 1;
})

Answer 2

使用map和Object.assign

var output = arr.map( s => Object.assign( s, s, { 'new_va' : 1 } ) )

演示

 var arr = [{ id : 1, name : "xyz", section : "b" },{ id : 2, name : "abc", section : "a" }] var output = arr.map( s => Object.assign( s, s, { 'new_va' : 1 } ) ); console.log(output);

Answer 3

尝试这个

 var arr = [{ id: 1, name: 'xyz', section: 'b' }, { id: 2, name: 'abc', section: 'a' }]; arr.forEach(ele => ele.new_va = 1); console.log(arr);
