目录结构如下：

本节教程我会带大家使用 HTML 、CSS和 JS 来制作一个 2048网页版小游戏

本节示例将会实现如下所示的效果：

HTML源码

使用<header></header>添加头部2048标题

复制
<header>
    <div class="container">
        <h><span>2</span><span>0</span><span>4</span><span>8</span></h1>
        <p class="inspired">by <a href="https://blog.csdn.net/qq_" rel="external nofollow"  target="_blank">海拥✘</a></p>
    </div>
</header>

效果：

添加一个 container 容器

复制
<div class="container">
</div>

添加游戏的主体部分

复制
<div class="directions">
        <p id="haiyong" class="haiyong"><strong>如何玩：</strong> 使用键盘方向键键移动数字方块。相邻的两个方块数字相同，它们可合并成一个！</p>
    </div>
    <div class="scores">
        <div class="score-container best-score">
            历史最佳:
            <div class="score">
                <div id="bestScore"></div>
            </div>
        </div>
        <div class="score-container">
            分数:
            <div class="score">
                <div id="score"></div>
                <div class="add" id="add"></div>
            </div>
        </div>
    </div>
    <div class="game">
        <div id="tile-container" class="tile-container"></div>
        <div class="end" id="end">游戏结束<div class="monkey">🙈</div><button class="btn not-recommended__item js-restart-btn"
             id="try-again">再试一次</button></div>
    </div>

效果：

重新启动游戏

复制
<div class="not-recommended">
        <button class="btn not-recommended__item js-restart-btn" id="restart">重新启动游戏</button>
        <span class="not-recommended__annotation"></span>
    </div>

底部导航栏

复制
<footer>
  <span class="author">Created by <a href="https://haiyong.site/about" rel="external nofollow" >Haiyong</a></span>        
  <span class="center"></span>        
  <span class="opposite">更多游戏:<a href="https://code.haiyong.site/moyu" rel="external nofollow" >摸鱼</a></span>
</footer>

JS 源码

js 代码较多，这里提供部分

复制
function handleKeypress(evt) {
  var modifiers = event.altKey || event.ctrlKey || event.metaKey || event.shiftKey;
  var whichKey = event.which;
 
  var prevGame = [].concat(game);
 
  if (!modifiers) {
    event.preventDefault();
    switch (whichKey) {
      case:
        game = shiftGameLeft(game);
        break;
      case:
        game = shiftGameUp(game);
        break;
      case:
        game = shiftGameRight(game);
        break;
      case:
        game = shiftGameDown(game);
        break;
    }
    game = game.map(function (tile, index) {
      if (tile) {
        return _extends({}, tile, {
          index: index
        });
      } else {
        return null;
      }
    });
    addRandomNumber();
    updateDOM(prevGame, game);
    if (gameOver()) {
      setTimeout(function () {
        endDiv.classList.add('active');
      },);
      return;
    }
  }
}
 
function newGameStart() {
  document.getElementById('tile-container').innerHTML = '';
  endDiv.classList.remove('active');
  score =;
  scoreDiv.innerHTML = score;
  initGame();
  drawBackground();
  var previousGame = [].concat(game);
  addRandomNumber();
  addRandomNumber();
  updateDOM(previousGame, game);
}
 
newGameStart();
