javascript - 等待按钮点击后再继续

Question

我弹出一个警报，询问“你想玩吗”，如果答案为真，它会运行一些代码。但是在您单击"is"之后，我希望按下一个按钮，并且我的代码继续运行而不等待按下它。

这是我的 Javascript:

var start = confirm("Would you like to Play?");
var plays = 0;
var playerScore = 0;
var computerScore = 0;
var userChoice = ""
function choose(buttonChoice) {
    userChoice = buttonChoice;
}

while(start) {

    var pScoreDiv = document.getElementById('pScore');
    pScoreDiv.innerHTML  = playerScore;

    var cScoreDiv = document.getElementById('cScore');
    cScoreDiv.innerHTML  = computerScore;

    console.log(playerScore);
    console.log(computerScore);

    var computerChoice = Math.random();

    if (computerChoice < 0.34) {
        computerChoice = "rock";
    } else if(computerChoice <= 0.67) {
        computerChoice = "paper";
    } else {
        computerChoice = "scissors";
    }
}

<button onClick="choose('rock')">Rock</button>
<button onClick="choose('paper')">Paper</button>
<button onClick="choose('scissors')">Scissors</button>

您只监听要选择的确认按钮，而不是要单击的按钮。

在下面的代码中，我将 while 更改为一个函数，用于检查 start 是否已设置，并在单击按钮时调用。

var start = confirm("Would you like to Play?");
var plays = 0;
var playerScore = 0;
var computerScore = 0;
var userChoice = ""

function choose(buttonChoice) {
  userChoice = buttonChoice;
  play();
}

function play() {
  if (start) {
    var pScoreDiv = document.getElementById('pScore');
    pScoreDiv.innerHTML = playerScore;

    var cScoreDiv = document.getElementById('cScore');
    cScoreDiv.innerHTML = computerScore;

    console.log(playerScore);
    console.log(computerScore);

    var computerChoice = Math.random();

    if (computerChoice < 0.34) {
      computerChoice = "rock";
    } else if (computerChoice <= 0.67) {
      computerChoice = "paper";
    } else {
      computerChoice = "scissors";
    }
  }
}

<button onClick="choose('rock')">Rock</button>
<button onClick="choose('paper')">Paper</button>
<button onClick="choose('scissors')">Scissors</button>
