Question

我有一个问题，我怎么能在一个阵列中混洗这个？请帮助我。我非常感谢你们帮助你们，非常感谢你们！

我想要做的是在一个阵列中洗牌。

    // ______________________________________________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;
}

// ______________________________________________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;

};

这里是其他代码，我认为这里存在的问题是否存在？：

// ______________________________________________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));

}

将此用于随机播放功能：

o.sort(function() {return 0.5 - Math.random()})
