如何使用OR||逻辑运算符验证用户输入的ID，是石头，纸张还是剪刀？

问题描述

我如何使获胜者的代码打印结果和控制台的计数器？ 代码的顶部现在可以正常运行。我当前的挑战是代码不会通过if / else条件，并且不会打印到控制台/代码的条件部分似乎没有运行。 我已经尝试过==和===，但没有一个起作用。我错过了什么吗？

    //get computer choices
    comChoices = ["rock","paper","scissors"]; 

    function playRound() {
    //get user input
    userInput = prompt("please enter rock,paper or scissors"); 
    //verify its in lowercase
    userInput = userInput.toLowerCase(); 

    if (
        userInput === "rock" ||
        userInput === "paper" ||
        userInput === "scissors"
    ) {
        function comrand() {
        // function selects a random computer choice
        randomChoice = comChoices[Math.floor(Math.random() * 
        comChoices.length)];
        return randomChoice;
        }
        window.alert(comrand());
    } else {
        // veirfy user input
        window.alert("please enter rock,paper or scissors or check your 
    spelling");
        playRound();
    }
    }

    //initialize count default
    userWin = 0;            
    comWin = 0;
    draw = 0;


    //conditionals to determine winners
    if (userInput == "rock" && randomChoice == "scissors"){               
        userWin++;
        console.log("You win!!! (rock crushes scissors)");
    } else if(userInput  == "scissors" && randomChoice =="rock"){
        comWin++;
        console.log("Computer wins!!!(rock crushes scissors)");
    } else if(userInput == "scissors" && randomChoice == "paper"){
        userWin++;
        console.log("You win!!! (Scissors cuts paper)");
    } else if(userInput == "paper" && randomChoice == "scissors"){
        comWin++;
        console.log("Computer win!s!! (Scissors cuts paper)");
    } else if(userInput == "paper" && randomChoice == "rock"){
        userWin++;
        console.log("You win!!! (paper covers rock)");
    } else if(userInput == "rock" && randomChoice == "paper"){
        comWin++;
        console.log("Computer win!s!! (paper covers rock)");
    } else {
        draw++;
        console.log("game is a draw");
    }
     
    

    if (userWin === 5){                                              // 
    conditions to determines the overall winner
        console.log("User wins the game");
    } else if (comWin === 5){
        console.log("computer wins the game");
    } else {
        console.log("the game is a draw");
    }

    playRound();
