如何在 JavaScript 数组中将两个字符串字段连接为一个？

Question

我有一个看起来像这样的数组：

[
  {"firstName": "john", "lastName": "doe", "linkedInID":"..."},   
  {"firstName": "jane", "lastName": "doe", "linkedInID":"..."},
  {"firstName": "someone", "lastName": "Mc Donald", "linkedInID":"..."},
  ...
]

我希望它合并到：

[
  {"Name": "john doe", "linkedInID": "..."},   
  {"Name": "jane doe", "linkedInID": "..."},
  {"Name": "someone Mc Donald", "linkedInID": "..."},
  ...
]

所有新对象都应该有一个字段Name，它是firstNameand的串联lastName。

我怎样才能做到这一点？

为什么你需要 Angular 呢？一种可能性是使用本机.map()javascript 方法来转换您的输入数组：

var inputArray = [
    {"firstName":"john","lastName":" doe","linkedInID":"..."},   
    {"firstName":"jane","lastName":"doe","linkedInID":"..."},
    {"firstName":"someone","lastName":"Mc Donald","linkedInID":"..."},
    ...
];

var result = inputArray.map(function(item) {
    return {
        Name: item.firstName + ' ' + item.lastName,
        linkedInID: item.linkedInID
    };
});
