我創(chuàng)建了一個(gè)非常基本的剪刀石頭布射擊游戲，您可以在其中使用 JavaScript 函數(shù)與計(jì)算機(jī)對(duì)戰(zhàn)。我有一個(gè)非?；镜?HTML 框架，其中有一個(gè)按鈕。我試圖在按下時(shí)啟動(dòng)提示（游戲）。提示按我想要的方式工作，但一旦我打開(kāi)窗口它就會(huì)啟動(dòng)腳本。我試圖僅在按下 html 上的按鈕時(shí)啟動(dòng)腳本。當(dāng)我按下按鈕時(shí)，控制臺(tái)出現(xiàn)錯(cuò)誤getPlayerChoice 未在 HTMLButtonElement.onclick 中定義這是我的代碼：let playerWinCount = 0;let computerWinCount = 0;let roundCount = 0;function playRound() {function computerPlay() {    let arr = ["Rock", "Paper", "Scissors"];    let compChoice = arr[Math.floor(Math.random() * arr.length)];        return compChoice;}//function getPlayerChoice() {    var str = prompt("What is your selection for this round?");    if (!str) {        return;}    let newStr = str.toLowerCase();    let capStr = newStr[0].toUpperCase() + newStr.slice(1);        if (capStr !== "Rock" && capStr!== "Paper" && capStr !== "Scissors") {        return;} else {        return capStr;    }}//    let playerSelection = getPlayerChoice();    let computerSelection = computerPlay();                    if (playerSelection === computerSelection) {        alert("Try again... You both chose " + playerSelection + "!");        return;} else {        if (playerSelection === "Rock") {        if (computerSelection === "Scissors") {        alert("You win! Rock beats Scissors!");        playerWinCount++;        roundCount++;        console.log("Player wins! Current score: Player-" + playerWinCount + ", Computer-" + computerWinCount);        return;} else if (computerSelection === "Paper") {        alert("You lose! Paper beats Rock!");        computerWinCount++;        roundCount++;        console.log("Computer wins! Current score: Player-" + playerWinCount + ", Computer-" + computerWinCount);        return;    }    } else  if (playerSelection === "Paper") {        if (computerSelection === "Rock") {        alert("You win! Paper beats Rock!");        playerWinCount++;        roundCount++;        console.log("Player wins! Current score: Player-" + playerWinCount + ", Computer-" + computerWinCount);        return;    } 我注釋掉了我的提示功能，因?yàn)槊慨?dāng)程序運(yùn)行時(shí)，它都會(huì)啟動(dòng)無(wú)法關(guān)閉的提示。如果沒(méi)有輸入，我需要一種關(guān)閉提示窗口的方法。
