使用原型功能将新创建的整个对象推入数组

Question

I am trying to run a function on the construction of my objects which passes the whole object to a function, which then pushes it to an array.

I can pass one property at a time like this:

    function Item(title, description, price) {
    'use strict';
    this.title = title;
    this.description = description;
    this.getPrice = function (price) {
        var pricestring = "£";
        pricestring = pricestring + price;
        return pricestring;
    };
    this.addToPage(this.title, this.description);
}

But I would like to be able to pass the whole object like this:

this.addToPage(this.Item);

however it always returns undefined.

My addToPage is function is like this:

Item.prototype.addToPage = function (item) {
    'use strict';
    constructedItems.push(item);
};

Is it actually possible to pass the whole object from inside the object? or is there another technique I could use?

您正在寻找this ，它是指正在构造的对象。
