Question

我试图在不使用for循环的情况下创建一副牌。我收到错误“ Uncaught SyntaxError：第189行的意外令牌”第189行是“创建卡”的行

var deck = {
suit: suit = ["Diamond", "Heart", "Club", "Spade"],
name: name = ["Nine", "Ten", "Jack", "Queen", "King", "Ace"],
cards: cards = [],
createcards: for (var i = 0; i < suit.length; i++){
        for (var j = 0; j < name.length; j++){
        deck.cards.push(card(name[j], suit[i]))
    }
},

draw: function (player){
    randnumber = Math.floor((Math.random() * cards.length))
    player.push[cards[randnumber]];

}
};

Answer 1

将cretaecards设置为匿名函数：

createcards: function(){
    for (var i = 0; i < deck.suit.length; i++){
            for (var j = 0; j < deck.name.length; j++){
            deck.cards.push(card(deck.name[j], deck.suit[i]))
        }
    }
},

您必须在文字对象中定义一个函数。

var deck = {
suit: suit = ["Diamond", "Heart", "Club", "Spade"],
name: name = ["Nine", "Ten", "Jack", "Queen", "King", "Ace"],
cards: cards = [],
createcards: function() {
     for (var i = 0; i < suit.length; i++) {
        for (var j = 0; j < name.length; j++) {
           deck.cards.push(card(name[j], suit[i]))
        }
     }
 }
},

Answer 3

您应该将createcards分配给匿名函数，如下所示：

createcards: function () {
    for (var i = 0; i < suit.length; i++) {
        for (var j = 0; j < name.length; j++) {
            deck.cards.push(card(name[j], suit[i]));
        }
    }
}

Answer 4

使用一个函数，如下所示：

var deck = {
suit: suit = ["Diamond", "Heart", "Club", "Spade"],
name: name = ["Nine", "Ten", "Jack", "Queen", "King", "Ace"],
cards: cards = [],
createcards: 
    function() {
        for (var i = 0; i < suit.length; i++){
            for (var j = 0; j < name.length; j++){
                deck.cards.push(card(name[j], suit[i]))
            }
        } 
    },
draw: function (player){
    randnumber = Math.floor((Math.random() * cards.length))
    player.push[cards[randnumber]];

}

};

您可以像这样调用Object中的函数：

deck.createcards();

但我建议您查看以下行：

deck.cards.push(card(name[j], suit[i]))

因为这里没有功能卡......

如何在函数中放置for循环？
