javascript - 如何将显示所有卡片按钮添加到下面的 javascript 代码中？

转载作者：行者123 更新时间：2023-12-01 17:17:32

我这里有这段代码是用 javascript、HTML 和 CSS 语言编写的，用于内存游戏，我想在这里的代码中添加一个显示所有按钮(点击它会显示所有卡片几秒钟，然后再次翻转)但是它不适合我，我在下面发布了代码，所以如果你能提供帮助，我将不胜感激。提前致谢:D

最佳答案

查看控制台，可以看到如下错误:

index.html:13 Uncaught ReferenceError: shuffleCards is not defined

这意味着您的按钮无法访问函数 shuffleCards，解决此问题的一种方法是在您的 ready() 中获取元素并将其连接到游戏是这样的:

let showAll = document.querySelector(".show-all");
showAll.addEventListener("click", () => {
  game.cardsArray.forEach((card) => card.classList.add("visible"));
});

<button class="show-all">Show All</button>

请检查以下代码段:

class MixOrMatch {
  constructor(totalTime, cards) {
    this.cardsArray = cards;
    this.totalTime = totalTime;
    this.timeRemaining = totalTime;
    this.timer = document.getElementById("timer");
    this.ticker = document.getElementById("flips");
  }

  startGame() {
    this.totalClicks = 0;
    this.timeRemaining = this.totalTime;
    this.cardToCheck = null;
    this.matchedCards = [];
    this.busy = true;
    this.timeRemaining = 0;
    setTimeout(() => {
      this.shuffleCards(this.cardsArray);
      this.countdown = this.startCountdown();
      this.busy = false;
    }, 500);
    this.hideCards();
    this.timer.innerText = this.timeRemaining;
    this.ticker.innerText = this.totalClicks;
  }
  startCountdown() {
    let minute = 0;
    let second = 0;
    return setInterval(() => {
      timer.innerHTML = minute + "mins : " + second + "secs";
      second++;
      if (second == 60) {
        minute++;
        second = 0;
      }
      if (minute == 60) {
        hour++;
        minute = 0;
      }
    }, 1000);

    this.timeRemaining++;
    this.timer.innerText = this.timeRemaining;
  }

  victory() {

    setTimeout(() => {
      card1.classList.remove("visible");
      card2.classList.remove("visible");
      this.busy = false;
    }, 1000);
  }
  shuffleCards(cardsArray) {
    for (let i = cardsArray.length - 1; i > 0; i--) {
      let randIndex = Math.floor(Math.random() * (i + 1));
