自动完成所需的 AngularJS 多个范围

Question

我有一个这样的数组结构。

[
  {
    "id": "1",
    "name": "John",
    "city": "NY"
  },
  {
    "id": "2",
    "name": "Gerold",
    "city": "LA"
  },
  {
    "id": "3",
    "name": "Stuart",
    "city": "Boston"
  }  
]

我需要像下面这样的 $scope 来进行自动完成搜索。

$scope.name=["john","Gerold","Stuart"];
$scope.city=["NY","LA","Boston"];

任何人都可以使用 angularjs Controller 帮助获得它。提前致谢!

Answer 1

使用 map

$scope.users = [
  {
  "id": "1",
  "name": "John",
  "city": "NY"
  },
 {
  "id": "2",
  "name": "Gerold",
  "city": "LA"
 },
 {
   "id": "3",
  "name": "Stuart",
  "city": "Boston"
 }  
];

$scope.cities = $scope.users.map(function(obj){ 

 return obj.city;
});

console.log($scope.cities);
