javascript - names.forEach 不是函数

Question

我正在尝试创建一副纸牌，但在运行 deckOfCards 时出现标题错误。

function deckOfCards() {
    const names = ['A','2','3','4','5','6','7','8','9','10','J','Q','K'];
    const suits = ['Hearts','Diamonds','Spades','Clubs'];
    var deck = new Array(); 

    function card(name, suits) {
        this.name = name;
        this.suits = suits;
    }

    function createDeck() {
        suits.forEach(function (names) {
            names.forEach(function (type) {
                deck.push(new card(type, weight));
            });
        });
    }

    createDeck();
}

Ok, I think this is what you were going for. I changed deckOfCards to be an object. Then fixed the createDeck variable issues.

Javascript:jsFiddler

var deckOfCards = {
    names : ['A','2','3','4','5','6','7','8','9','10','J','Q','K'],
    suits : ['Hearts','Diamonds','Spades','Clubs'],
     deck : []
}

function card(name, suits){
    this.name = name;
    this.suits = suits;
}

function createDeck(){
    deckOfCards.suits.forEach(function (suit) {
        deckOfCards.names.forEach(function (name) {
           deckOfCards.deck.push(new card(name, suit));
        });
    });
}

createDeck();
console.log(deckOfCards.deck);
