Question

假设我有一个简单的模型，如下：

var person = {
    name: "Bob",
    age: "30"
}

但是我如何将新对象插入现有对象？假设我创建了一个新对象：

var pets = [{name: "Lucky", type: "Dog"}, {name: "Paws", type: "Cat"}];

我需要动态生成各种模型并将它们插入到模型的各个部分中。

我的最终模型看起来像这样：

var person = {
        name: "bob",
        age: "30",
        pets: [
            {name: "Lucky", type: "dog"},
            {name: "Paws", type: "Cat"}
        ]
    };

Answer 1

我不确定我是否完全理解您的问题，但我如何理解，您需要做的只是设置person的新属性。

var person = {
        name: "Bob",
        age: "30"
    },
    pets = [{ name: "Lucky", type: "Dog" }, { name: "Paws", type: "Cat" }];

person.pets = pets;

console.log(person); // Object: (String) name, (String) age, (Array) pets;

您也可以使用EMCAScript 5的Object.create()方法。

在person中创建一个数组：

person.pets = [
   {name: "Lucky", type: "dog"},
   {name: "Paws", type: "Cat"}
];

或

var pets = [{name: "Lucky", type: "Dog"}, {name: "Paws", type: "Cat"}];
person.pets = pets;

将对象动态插入现有对象
