javascript - 以编程方式构造对象数组

Question

假设我希望对象是这样的:

var Book = {
        title: "the catcher in the rye",
        price: "80.98",
        characters: [{name: "holden caulfield", age: 16, height:"6.2"},
                     {name: "phoebe caulfield",age:13, height: "5"}] 
     };

问题: characters 数组是通过一个字符一个一个地添加来构建的。如何在确保名称、年龄和高度属性如上定义的同时做到这一点。

有什么效果吗？

Book.characters.add({name: "phoebe caulfield",age:13, height: "5"});

我希望能够以编程方式定义它，即向对象添加属性而不是像这样定义它。

这可能吗？

Answer 1

您可以像这样在动态代码(而不是静态声明)中执行此操作:

var Book = {};

Book.title = "the catcher in the rye";
Book.price = "80.98";
Book.characters = [];
Book.characters.push({name: "holden caulfield", age: 16, height: "6.2"});
Book.characters.push({name: "phoebe caulfield", age: 13, height: "5"});
