Javascript 使用交换机时出现意外令牌？

尝试使用switch语句进行石头剪纸游戏，但不断获得预期的令牌，似乎无法找出原因：/。控制台突出显示了分号，所以我删除了这些，但仍然没有运气

在使用switch语句之前，我在控制台中测试了这个游戏，它似乎工作得很好

const userScore = 0;
const computerScore = 0;
const userScore_span = document.getElementById("user-score");
const computerScore_span = document.getElementById("computer-score");
const scoreBoard_div = document.querySelector(".score-board");
const result_div = document.querySelector(".result");
const rock_div = document.getElementById("r");
const paper_div = document.getElementById("p");
const scissors_div = document.getElementById("s");
const lizard_div = document.getElementById("l");
const spock_div = document.getElementById("k");

function getComputerChoice() {
    const choices = ['r', 'p', 's', 'l', 'k'];
    const randomNumber = Math.floor(Math.random() * 5);
    return choices[randomNumber];
}

function game(userChoice) {
    const computerChoice = getComputerChoice();
    switch (userChoice + computerChoice) {
        case "rs";
        case "rl";
        case "pr";
        case "pk";
        case "sp";
        case "sl";
        case "lk";
        case "lp";
        case "ks";
        case "kr";
            console.log("USER WINS");
            break;
        case "rk";
        case "rp";
        case "ps";
        case "pl";
        case "sr";
        case "sk";
        case "lr";
        case "ls";
        case "kp";
        case "kl";
            console.log("COMPUTER WINS");
            break;
        case "rr"
        case "pp"
        case "ss"
        case "ll"
        case "kk"
            console.log("Its a draw");
    }   
}

function main() {
    rock_div.addEventListener('click', function() {
    game("r")
    })

    paper_div.addEventListener('click', function() {
    game("p")
    })

    scissors_div.addEventListener('click', function() {
    game("s")
    })

    lizard_div.addEventListener('click', function() {
    game("l")
    })

    spock_div.addEventListener('click', function() {
    game("k")
    })
}

    main();

我试着四处搜索，但我发现大多数错误都是由于人们在代码中没有使用swith语句造成的，所以决定发表我自己的帖子。

你需要冒号，而不是分号。参见文档中的示例：
