创建对象的实例与创建相同类型的对象相同吗？

Question

我必须创建一个对象，三个对象和数组实例。

创建具有以下属性的巡航对象：
巡航日期，
游轮目的地，
巡航说明，
Cruise URL，
船名，
船舶描述，
发货地址， 价

制作三个巡航物体实例 创建三个实例的数组。

根据我的理解，我创建了一个包含所有属性的巡航对象，我必须再创建三个对象实例。

我做了以下事情。创建实例是否意味着创建相同类型的对象？

    function Cruise(cruise_Date, cruise_Destination, cruise_URL, ship_Name, ship_Description, ship_url, price ) {
        this.cruise_Date = cruise_Date;
        this.cruise_Destination = cruise_Destination;
        this.cruise_URL = cruise_URL;
        this.ship_Name = ship_Name;
        this.ship_Description = ship_Description;
        this.ship_url = ship_url;
        this.price = price
  }


    var myCruise = new cruise("16 March 2018", 

        '<a href="#">4 Night Bahmas cruise </a>', 
        "You know the name, the laid-back attitude and where to find them, but you’ll just have to visit The Bahamas to truly appreciate this classic cruise destination. On this 700-strong string of sun-splashed islands dotting the blue Atlantic, the living’s easy. (And it’s not bad on a Bahamas cruise either!) The central port of Nassau is the bustling capital of the country — bustling is a relative term, of course — while Freeport is all chill, all the time. And nothing is as delightfully desolate as Half Moon Cay and Princess Cays: pure private-destination paradise",

    var myCruise2 = new cruise("Cruise_Date", "Cruise_Destination", "Cruise_Description", "Cruise_URL", "Ship_Name", "Ship_Description", "Ship_URL", "Price");

    var myCruise3 = new cruise("Cruise_Date", "Cruise_Destination", "Cruise_Description", "Cruise_URL", "Ship_Name", "Ship_Description", "Ship_URL", "Price");



    list = new Array("Departs", "Destination", "Ship", "Price from");
    instances = new Array(myCruise, myCruise2, myCruise3);

    function displayList(the_date, ) {
        // body...
    }

创建对象时的代码存在一些问题。你需要有一个名为cruise（）的对象构造函数来实现它。通常，您将对象构造函数大写。另外，我怀疑他们是否打算给你提供与属性名称相同的每个属性的值。如果你要给出一个巡航物体的实例，你会给它一个真实的目的地，比如＆＃34;巴哈马＆＃34;等等。对象构造函数看起来像这样：

＆＃13;

＆＃13;

function Cruise(date,destination,descr,url,name,price){
  this.cruiseDate = date;
  this.cruiseDestination = destination;
  this.cruiseDescription = descr;
  this.cruiseUrl = url;
  this.cruiseName = name;
  this.cruisePrice = price;
}

＆＃13;

＆＃13;

＆＃13;

至于创建一个对象数组，在用它们的实际值创建对象的实例后，你可以把它们放在一个数组文字中，除非你应该用另一种方式做

var instances = [myCruise，myCruise2，myCruise3];
