我正在尝试开发一个骰子游戏，其中两个骰子同时滚动，并生成随机数字。在这里，我使用了3-D骰子(不使用骰子图像)，一切都很好。我想再添加一件事:我希望数字出现在屏幕上骰子的正面，例如-“数字是2,3或4，5”。我需要在写这段代码的帮助。

我不知道该从何说起。我想做到这一点使用JavaScript，超文本标记语言，CSS。

function rollDice() {
  const dice = [...document.querySelectorAll(".die-list")];
  dice.forEach(die => {
    toggleClasses(die);
    die.dataset.roll = getRandomNumber(1, 6);
  });
}

function toggleClasses(die) {
  die.classList.toggle("odd-roll");
  die.classList.toggle("even-roll");
}

function getRandomNumber(min, max) {
  min = Math.ceil(min);
  max = Math.floor(max);
  return Math.floor(Math.random() * (max - min + 1)) + min;
}

document.getElementById("roll-button").addEventListener("click", rollDice);

**CSS**

代码可以在this CodePen中找到。你可以看一下骰子。

在骰子停止滚动后，它必须看起来如下所示：

数字是- 2,3

这些数字是基于骰子的正面。

你几乎就有了它，你只需要抓取每个骰子的值并显示它们。

我添加了下面的div，每个骰子值都有一个跨度。我使用is来匹配哪个骰子是哪个。

代码语言：javascript
复制
<div>Your values are <span id="die-1-val"></span> <span id="die-2-val"></span></div>

这是我需要添加的唯一JS，我将它放在forEach中。

代码语言：javascript
复制
document.getElementById(die.id+"-val").innerText = die.dataset.roll;

工作示例...

​

代码语言：javascript
复制
function rollDice() {
  const dice = [...document.querySelectorAll(".die-list")];
  let dice1Val, dice2Val;
  dice.forEach(die => {
    toggleClasses(die);
    die.dataset.roll = getRandomNumber(1, 6);
    document.getElementById(die.id+"-val").innerText = die.dataset.roll;
  });
}

function toggleClasses(die) {
  die.classList.toggle("odd-roll");
  die.classList.toggle("even-roll");
}

function getRandomNumber(min, max) {
  min = Math.ceil(min);
  max = Math.floor(max);
  return Math.floor(Math.random() * (max - min + 1)) + min;
}

document.getElementById("roll-button").addEventListener("click", rollDice);
