在继续之前等待按钮单击

Question

我有一个警告弹出询问 "would you like to play" 如果答案是真的它运行一些代码。但是在您单击 "yes" 之后，我希望按下一个按钮，并且我的代码会继续运行而无需等待它被按下。

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>

Answer 1

尝试

if (start == true) {

而不是

while (start) {

Answer 2

您只监听要选择的确认按钮，而不是要点击的按钮。

在下面的代码中，我将 while 更改为检查是否已设置 start 的函数，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>
