Question

我有一个JSON结构;

{ 
  books: [ 
    {"id": "book1", "title": "Book One"}, 
    {"id": "book2", "title": "Book Two"} 
  ] 
}

代表;

function BookList() {
    this.books = new Array();
}

BookList.prototype.addBook = function(b) {
    this.books[this.books.length] = b;
}

function Book(id, title) {
    this.id = id ||   ;
    this.title = title ||   ;
    this.chapters = new Array();
}

Book.prototype.addChapter = function(c) {
    this.chapters[this.chapters.length] = c;
}

在图书管理员内部创建各种图书物体的最佳方式是什么?

凭借 j,你只能使用<代码>$.parseJSON(jsonData).books,指定书记官阵列,并自动拥有财产价值,但并不创造具有原型功能的必要物体。

Is the only way to iterate over the JSON array and create each Book object individually? This question covers creating a particular prototyped object from JSON: Parse JSON String into a Particular Object Prototype in JavaScript.

我认为,这可以延伸到具有适当频率的图书管理员,并从那里适用于图书标的章节。

在初始转让之后,是否可以将物体类型改为$.parseJSON?

var json = { 
  books: [ 
    {"id": "book1", "title": "Book One"}, 
    {"id": "book2", "title": "Book Two"} 
  ] 
};

var list = new BookList();
list.books = json.books.map(convertToBook);

function convertToBook(book) {
  return new Book(book.id, book.title);
}
