我目前在使用 javascript 时遇到问题。请帮助我如何在数组中随机播放这个。我真的很感激任何帮助。太感谢了！

    // ______________________________________________Function to declare our var -> deck of cards

function getDeck() {

    var deck = [
        {suit: "H", face: "A"},
        {suit: "H", face: "2"},
        {suit: "H", face: "3"},
        {suit: "H", face: "4"},
        {suit: "H", face: "5"},
        {suit: "H", face: "6"},
        {suit: "H", face: "7"},
        {suit: "H", face: "8"},
        {suit: "H", face: "9"},
        {suit: "H", face: "10"},
        {suit: "H", face: "J"},
        {suit: "H", face: "Q"},
        {suit: "H", face: "K"},
        {suit: "C", face: "A"},
        {suit: "C", face: "2"},
        {suit: "C", face: "3"},
        {suit: "C", face: "4"},
        {suit: "C", face: "5"},
        {suit: "C", face: "6"},
        {suit: "C", face: "7"},
        {suit: "C", face: "8"},
        {suit: "C", face: "9"},
        {suit: "C", face: "10"},
        {suit: "C", face: "J"},
        {suit: "C", face: "Q"},
        {suit: "C", face: "K"},
        {suit: "D", face: "A"},
        {suit: "D", face: "2"},
        {suit: "D", face: "3"},
        {suit: "D", face: "4"},
        {suit: "D", face: "5"},
        {suit: "D", face: "6"},
        {suit: "D", face: "7"},
        {suit: "D", face: "8"},
        {suit: "D", face: "9"},
        {suit: "D", face: "10"},
        {suit: "D", face: "J"},
        {suit: "D", face: "Q"},
        {suit: "D", face: "K"},
        {suit: "S", face: "A"},
        {suit: "S", face: "2"},
        {suit: "S", face: "3"},
        {suit: "S", face: "4"},
        {suit: "S", face: "5"},
        {suit: "S", face: "6"},
        {suit: "S", face: "7"},
        {suit: "S", face: "8"},
        {suit: "S", face: "9"},
        {suit: "S", face: "10"},
        {suit: "S", face: "J"},
        {suit: "S", face: "Q"},
        {suit: "S", face: "K"},
    ];

    return deck;
}

这是洗牌代码。我不知道这是否正确，所以请也检查一下。谢谢！

// ______________________________________________Function to shuffle cards

function shuffle(o) { // o is passed-in array

     for (var j, x, i = o.length; i; j = parseInt(Math.random() * i, 10), x = o[--i], o[i] = o[j], o[j] = x);
     return o;

};


// ______________________________________________Function to retrieve our deck of cards & save into localStorage

function getShoe(decks) {

    var shoe = [];
    var deck = getDeck();
    this.decks = decks;

        for (z=1;z<=decks;z++) {
            shoe.push(deck);
        }

    shoe = shuffle(shoe);
    return shoe;


    localStorage.setItem('shoe', JSON.stringify(shoe));

}

你在这里做的是：

var shoe = [];          // create an empty array
var deck = getDeck();   // create a SINGLE deck
this.decks = decks;

    for (z=1;z<=decks;z++) {
        shoe.push(deck);  // insert the SAME deck many times into the array
    }

shoe = shuffle(shoe); // you shuffle the array that contains the same deck many times, not the decks
return shoe;

你可以做：

var shoe = [];
for (var i=0; i<decks; i++){
    shoe.push(shuffle(getDeck()));
}
return shoe;
