在一个数组中，一个键有多个值，我想删除一个特定的值[重复]

Question

var cards = {
    heart:[2, 3, 4, 5, 6, 7, 8, 9, 10, "joker", "queen", "king", "ace"],
    spade:[2, 3, 4, 5, 6, 7, 8, 9, 10, "joker", "queen", "king", "ace"],
    diamond:[2, 3, 4, 5, 6, 7, 8, 9, 10, "joker", "queen", "king", "ace"],
    king:[2, 3, 4, 5, 6, 7, 8, 9, 10, "joker", "queen", "king", "ace"],
};



function cardSelectionForPlayer(){
    let x = Math.floor((Math.random() * 3) + 0);
    let y = Math.floor((Math.random() * Object.values(cards)[x].length-1) + 0);


    if (y==9 || y==10 || y==11) {
        playerHands.push(10);
    } else if (y==12){
        if ( ((playerHands.reduce((a,b) => a+b, 0))+11) < 21){
            playerHands.push(11);
        } else {
            playerHands.push(1);
        }
    } else {
    playerHands.push(Object.values(cards)[x][y]);2
    }
    delete Object.values(cards)[x][y];
}

我有一副牌，每次玩家随机选择一张牌时，这张牌就会从那副牌中移除。例如，我将如何专门从甲板上删除数字黑桃 3？

感谢您的宝贵时间和回答。

var cards = {
    heart:[2, 3, 4, 5, 6, 7, 8, 9, 10, "joker", "queen", "king", "ace"],
    spade:[2, 3, 4, 5, 6, 7, 8, 9, 10, "joker", "queen", "king", "ace"],
    diamond:[2, 3, 4, 5, 6, 7, 8, 9, 10, "joker", "queen", "king", "ace"],
    king:[2, 3, 4, 5, 6, 7, 8, 9, 10, "joker", "queen", "king", "ace"],
};

var category = "spade";
var value = 3;
var index = cards[category].indexOf(value);

cards[category].splice(index, 1);

console.log(cards);
