如何将其他对象添加到 Javascript 中的数组

Question

我想了解如何按照我创建的构造函数将一个对象添加到具有多个现有对象的数组中。

//constructor function
function Bookdes(title, author, pages, current_page, available){
    this.title = title;
    this.author = author;
    this.pages = pages;
    this.current_page = current_page;
    this.available = available;
}
//array of books
var bookarrays = [
    new Bookdes("Fast Cars", "John Burns", 205, 43, "true"),
    new Bookdes("Slow Cars", "Joe Fast", 70, 32, "false" ),
    new Bookdes("Big Cars", "Darla Jean", 234, 42, "true"),
    new Bookdes("Small Cars", "Dema Jones", 214, 34, "false"),
    new Bookdes("Cars", "Alex Best", 235, 41, "true")
];

//Add two more books
bookarrays.push("Gasoline Car", "Johnny Walker", 200, 31, "true");
bookarrays.push("Natural gas car", "James Dean", 150, 21, "true");
console.log(bookarrays);

谢谢，

问题是你没有调用构造函数。正确的调用是：

bookarrays.push(new Bookdes("Gasoline Car", "Johnny Walker", 200, 31, "true"));
