javascript - 从数组结果中获取两个字段

Question

我的服务给出的结果如下

$scope.ListOfPeople = [
    { PersonID: 10, FirstName: "John", LastName: "Smith", Sex: "Male" },
    { PersonID: 11, FirstName: "James", LastName: "Last", Sex: "Male" },
    { PersonID: 12, FirstName: "Mary", LastName: "Heart", Sex: "Female" },
    { PersonID: 13, FirstName: "Sandra", LastName: "Goldsmith", Sex: "Female" },
    { PersonID: 14, FirstName: "Shaun", LastName: "Sheep", Sex: "Male" },
    { PersonID: 15, FirstName: "Nicola", LastName: "Smith", Sex: "Male" }
];

我需要按如下方式自定义我的数据源

$scope.output= [
    { PersonID: 10, FirstName: "John" },
    { PersonID: 11, FirstName: "James" },
    { PersonID: 12, FirstName: "Mary" },
    { PersonID: 13, FirstName: "Sandra" },
    { PersonID: 14, FirstName: "Shaun" },
    { PersonID: 15, FirstName: "Nicola" }
];

在 angularjs 中执行此操作的最佳方法是什么

Answer 1

您可以使用 map 来实现您的目标。考虑到 map 创建了新数组。

$scope.output = $scope.ListOfPeople.map(function(item){
    return {
        PersonID: item.PersonID,
        FirstName: item.FirstName
    };
});
